In the description of the present application, "/" means or, for example, a/B may mean a or B, and "and/or" herein is merely an association relationship describing an association object, means that three relationships may exist, for example, a and/or B, and it may mean that a alone exists, while a and B exist, and B alone exists, unless otherwise stated.

It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

Before explaining the temperature raising method of the streaming media rearview mirror provided by the embodiment of the application, the structure of the streaming media rearview mirror related to the embodiment of the application is explained in detail.

For example, fig. 1 is a schematic structural diagram of a streaming media rearview mirror according to an embodiment of the present application. Referring to fig. 1, the streaming media rearview mirror includes a display screen module 101, a dimming glass 102, and a cover glass 103.

When the streaming media rearview mirror is horizontally placed as shown in fig. 1, the dimming glass 102 covers over the display screen module 101, and is used for adjusting the light transmittance of the display screen module 101. The light control glass 102 is a glass whose transparency can be changed by electric control (voltage). Specifically, the light transmittance of the light-adjusting glass 102 is generally directly related to the voltage applied thereto, that is, in the absence of the voltage, the light-adjusting glass 102 is in an opaque state, the light transmittance is very low and is close to zero, and as the voltage increases, the light transmittance of the light-adjusting glass 102 increases.

The cover glass 103 covers over the dimming glass 102 for protecting the dimming glass 102 and the display screen module 101 from damage.

In general, for a dimming glass that can adjust light transmittance and reflectance, it may include electrochromic glass, suspended particle device, liquid crystal dimming glass, thermochromic dimming glass. In the embodiment of the application, the dimming glass may be liquid crystal dimming glass. Which can change the transmittance and reflectance by changing the arrangement of liquid crystal molecules by a voltage.

As an example, the dimming glass 102 may employ a LC lens (Liquid CRYSTAL LENS ) with adjustable reflectivity. The LC lens includes a polarizer, a liquid crystal glass and an RPM film (REFLECTIVE POLARIZATION MODULATION, polarizing reflective film).

For example, fig. 2 is a schematic diagram of an operating principle of a streaming media rearview mirror according to an embodiment of the present application. Referring to fig. 2, the streaming rearview mirror includes a display screen module 201 and an LC lens 202. The LC lens 202 includes a polarizer 203, a liquid crystal-sandwiched glass 204, and an RPM film 205, among others.

In an embodiment of the application, the streaming rearview mirror comprises a streaming display mode and a reflecting mirror mode. The streaming media display mode is a mode in which an image of the rear of the vehicle is displayed by the display screen module 201. The mirror mode is a mode that reflects the environment behind the vehicle by the principle of optical reflection.

It should be noted that, the user may manually switch the two modes through a physical button disposed on the rearview mirror of the streaming media, or manually switch the two modes through a virtual button disposed on a central control screen of the vehicle, which is not limited in the embodiment of the present application. In addition, the vehicle may automatically switch between the two modes according to the vehicle state (for example, reverse, high-speed running, etc.).

As shown in (a) of fig. 2, in the case where the display module 201 is energized, the liquid crystal in the liquid crystal-sandwiched glass 204 is simultaneously energized to be turned over so that the transmittance of the LC lens 202 is maximized and the reflectance is minimized, and after the incident light passes through the polarizer 203, the reflectance is 50% and after continuing through the RPM film 205, the reflectance is 10%.

In this case, the streaming rearview mirror is in a streaming display mode, that is, a mode in which an image of the rear of the vehicle is displayed through the display screen module 201. The reflectivity through the LC lens 202 is the lowest and the transmittance is the highest, so that the image displayed by the display module 201 can be seen by the user through the LC lens 202.

As shown in fig. 2 (b), in the case where the display module 201 is not powered on, that is, in the case where the display module 201 is turned off, the alignment state of the liquid crystal in the liquid crystal-sandwiched glass 204 is not changed, so that the light transmittance of the LC lens 202 is small and the reflectance is large. In this case, the streaming rearview mirror is in a mirror mode, that is, a mode of reflecting the environment behind the vehicle by the principle of optical reflection. By increasing the reflectivity of LC lens 202, the light transmittance is reduced such that after light from the vehicle rear environment enters LC lens 202, reflection may be performed to further reflect light into the user's eyes so that the user may see the vehicle rear environment.

The following describes a display module in a streaming media rearview mirror.

For example, fig. 3 is a schematic structural diagram of a display screen module according to an embodiment of the present application. Referring to fig. 3, the display module may include a backlight 301 and a liquid crystal layer 302 (i.e., a liquid crystal display).

The backlight 301 is used for providing backlight for the display screen module, and the brightness of the backlight 301 is adjusted to enable a user to clearly see the picture displayed by the display screen module under different illumination conditions. Alternatively, the backlight 301 may be positioned on top of the display screen module to provide light to the display area below. Of course, the backlight 301 may also be located at the bottom, left side or right side of the display screen module, which is not limited in the embodiment of the present application.

As an example, the backlight 301 may be any one of a Light Emitting Diode (LIGHT EMITTING Diode), an Organic Light-Emitting Diode (OLED), or a Micro Light Emitting Diode (Micro LIGHT EMITTING Diode), but of course, the backlight may be other types of lamps, which is not limited thereto according to the embodiment of the present application.

The liquid crystal layer 302 is used for displaying pictures, and can realize the function of the streaming media rearview mirror by displaying pictures acquired by a camera at the rear of the vehicle.

The core of the development of the liquid crystal layer is "the alignment direction of the liquid crystal molecules changes", that is, the movement of the liquid crystal molecules. However, the liquid crystal material is very sensitive to the temperature of the environment, and the lower the temperature is, the slower the liquid crystal molecule overturning speed is, which means that the response time of the liquid crystal display screen is prolonged, namely, the smear phenomenon can occur, and the display effect is affected.

Therefore, the embodiment of the application provides a streaming media rearview mirror temperature rising method which can be applied to a scene of the streaming media rearview mirror in a preset temperature environment.

Specifically, the temperature of the streaming media rearview mirror is detected, and when the streaming media rearview mirror is detected to be in a preset temperature environment, the streaming media rearview mirror is controlled to start a mirror mode, namely, the streaming media rearview mirror is normally used by reflecting the image behind the vehicle through an optical reflection principle. And then the power of the backlight is increased so as to heat the streaming media rearview mirror by the heat emitted by the backlight. After the power of the backlight is increased, the use effect of the reflector mode is poor, so that the display screen module is controlled to display a preset picture, and light emitted by the backlight is shielded through the preset picture.

Therefore, when the temperature of the streaming media rearview mirror is raised through the heat emitted by the backlight, the preset picture shields the light emitted by the backlight, so that the temperature of the streaming media rearview mirror is raised through the backlight under the condition that the normal use of the rearview mirror by a user is not influenced. Therefore, the problem of smear of the streaming media rearview mirror in a special temperature environment can be solved, and the user experience is improved.

The method for heating the streaming media rearview mirror provided by the embodiment of the application is explained in detail below.

Fig. 4 is a flowchart of a temperature rising method of a streaming media rearview mirror according to an embodiment of the present application. The method may be applied to a vehicle configured with a streaming rearview mirror and may be applied to a streaming rearview mirror controller (Rearview Mirror Controller, RMC) of the vehicle. Referring to fig. 4, the method includes the following steps 401 and 402.

Step 401, under the condition that the streaming media rearview mirror is in a preset temperature environment, controlling the streaming media rearview mirror to start a reflecting mirror mode, wherein the streaming media rearview mirror comprises a display screen module, the display screen module comprises a backlight, and the reflecting mirror mode is a mode for reflecting the environment behind a vehicle through an optical reflection principle.

The streaming rearview mirror may be the streaming rearview mirror shown in the embodiment of fig. 1. The display module may be the display module shown in the embodiment of fig. 3, which includes a backlight.

The preset temperature environment may be predefined by a technician, for example, the technician may predefine a temperature range within which the streaming rearview mirror is located, i.e., the preset temperature environment. In the embodiment of the present application, the preset temperature environment may be a low temperature environment. For example, the temperature range set by the technician may be a temperature range in which the streaming rearview mirror is deactivated at a low temperature, and then the streaming rearview mirror may be considered to be in a low temperature environment when the streaming rearview mirror is in the temperature range.

In this case, when the streaming rearview mirror is in the preset temperature environment, it is indicated that the liquid crystal in the display screen module of the streaming rearview mirror may be deactivated due to low temperature, so that the response is slower, and then the phenomenon of low temperature smear may occur in the streaming rearview mirror. When the streaming media rearview mirror has low-temperature smear, the observation of a user on the rear situation of the vehicle can be influenced, so that the user experience can be reduced.

In the mirror mode, the liquid crystal does not need to turn over, so that the mirror mode is not affected by the activity of the liquid crystal when the streaming media rearview mirror is in a preset temperature environment, and the streaming media rearview mirror can be controlled to be in the mirror mode.

Under the condition that the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror is controlled to start a reflecting mirror mode, so that the working mode of the streaming media rearview mirror is that the environment behind a vehicle is reflected by an optical reflection principle. Therefore, the normal use of the streaming media rearview mirror by a user is not affected, and the user experience is further improved.

Specifically, the operation of controlling the streaming media rearview mirror to start the mirror mode may be to adjust the light transmittance of the dimming glass to a first light transmittance and adjust the reflectivity of the dimming glass to a first reflectivity.

The light-adjusting glass may be the light-adjusting glass shown in the embodiment of fig. 1, and the light-adjusting glass covers the display screen module. Alternatively, the dimming glass may be an LC lens with adjustable reflectivity.

The first light transmittance is the minimum light transmittance of the light-adjusting glass, and the first reflectivity is the maximum reflectivity of the light-adjusting glass. For example, the first light transmittance is 10% and the first reflectance is 100%. It will be appreciated that when the dimming glass is at its minimum light transmittance and maximum reflectance, i.e. the power to the dimming glass is turned off, i.e. no voltage is applied to the dimming glass at this time.

In the embodiment of the application, the light transmittance and the reflectivity of the dimming glass can be adjusted within a certain range. The larger the light transmittance of the dimming glass is, the clearer the picture display of the display screen module is. The smaller the light transmittance of the light-adjusting glass is, the less light rays of the picture displayed by the display screen module passes through the light-adjusting glass, and the more blurred or less the picture displayed by the display screen module is. The smaller the reflectivity of the dimming glass, the less the dimming glass reflects incident light, i.e., the less the environment behind the vehicle. The greater the reflectivity of the privacy glass, the more the privacy glass reflects incident light, i.e., the more the environment behind the vehicle.

Since the mirror mode reflects the environment behind the vehicle by the principle of optical reflection, the display screen module can be omitted. Therefore, the light transmittance of the dimming glass can be adjusted to be the lowest, so that the transmittance of the picture displayed by the display screen module is the lowest. In addition, the reflectivity of the light adjusting glass is adjusted to be the highest, so that the light adjusting glass can realize the basic reflection principle, and the environment behind the vehicle can be reflected.

In this case, the light transmittance of the light-adjusting glass is adjusted to the first light transmittance, and the reflectivity of the light-adjusting glass is adjusted to the first reflectivity, so that the light-adjusting glass can not penetrate through the screen display of the display screen module, and can reflect the environment behind the vehicle, so that the opening of the reflector mode can be realized.

It should be noted that, before step 401, it may also be determined whether the streaming rearview mirror is in a preset temperature environment.

Optionally, acquiring a target temperature of the streaming media rearview mirror, determining that the streaming media rearview mirror is in a preset temperature environment when the target temperature is smaller than a first temperature threshold, and determining that the streaming media rearview mirror is not in the preset temperature environment when the target temperature is greater than or equal to the first temperature threshold.

The target temperature is the temperature of the streaming media rearview mirror acquired at the current moment.

In the embodiment of the application, a temperature sensor, such as a thermistor sensor, can be configured in the streaming media rearview mirror. For example, the temperature sensor can be attached to the display screen module to detect the temperature, so that the temperature of the rearview mirror can be detected more accurately.

The first temperature threshold may be set in advance, and the first temperature threshold may be set smaller. In an embodiment of the present application, the first temperature threshold may be set according to the activity of the liquid crystal at different temperatures, and as an implementation manner, the first temperature threshold may be a critical temperature when the liquid crystal is deactivated. For example, the first temperature threshold is-12 degrees celsius (celsius).

When the target temperature is smaller than the first temperature threshold, the target temperature is smaller, or the target temperature is smaller than the temperature when the liquid crystal is deactivated, so that the liquid crystal in the streaming media rearview mirror may respond slowly when the power is on, and the streaming media rearview mirror may have a phenomenon of low-temperature smear, so that the streaming media rearview mirror is determined to be in a preset temperature environment.

When the target temperature is greater than or equal to the first temperature threshold, the target temperature is greater, or the target temperature is greater than the temperature when the liquid crystal is deactivated, that is, the target temperature is the temperature when the liquid crystal is normally active, so that the problem of low-temperature smear does not occur, and therefore it is determined that the streaming media rearview mirror is not in the preset temperature environment.

Step 402, power of the backlight is increased, and the display screen module is controlled to display a preset picture, so that the temperature of the streaming media rearview mirror is increased by heat emitted by the backlight, and light emitted by the backlight is shielded by the preset picture.

In the embodiment of the application, the preset picture is a picture capable of shielding light emitted by the backlight. The preset screen may be preset, and as an embodiment, the preset screen may be set to a solid-color screen, for example, the preset screen may be a solid-black screen.

The power of the backlight is increased, so that the backlight emits stronger light, and the emitted heat is increased. Therefore, the power of the backlight is increased, and the temperature of the streaming media rearview mirror can be increased by the heat emitted by the backlight.

Since the brightness of the backlight will be higher after the power of the backlight is turned up. The minimum light transmittance (e.g., 10%) of the light-adjusting glass is not transparent, and some light is transmitted, so that the stronger the light emitted from the backlight, the stronger the light transmitted through the light-adjusting glass, which affects the normal use of the reflector mode by the user, i.e., the reflected environment behind the vehicle cannot be seen clearly. Therefore, the power of the backlight lamp is increased, and the display screen module can be controlled to display a preset picture.

Therefore, the streaming media rearview mirror can be heated through the backlight under the condition that the streaming media rearview mirror is not normally used by a user, so that the problem of smear of the streaming media rearview mirror in a low-temperature environment can be solved under the condition that the streaming media rearview mirror is normally used, and the user experience is further improved.

It should be understood that when the display screen module is controlled to display the preset picture, the display of the picture acquired by the camera behind the vehicle is paused.

Alternatively, the operation of powering up the backlight may be achieved in two possible ways as follows.

In a first possible implementation, the power of the backlight is adjusted to the first power.

The first power is the maximum power of the backlight.

In this case, that is, the power of the backlight is adjusted to the maximum power that the backlight can withstand in a short time, that is, the backlight is put in a high power consumption mode in a short time. Therefore, the backlight lamp can emit more heat in a short time, and the streaming media rearview mirror can be heated up rapidly.

Therefore, the power of the backlight lamp is adjusted to the first power, so that the temperature of the streaming media rearview mirror is quickly increased, the temperature rise time of the streaming media rearview mirror can be shortened, and the temperature rise efficiency of the streaming media rearview mirror is improved.

In a second possible implementation manner, in response to a start instruction of the streaming media display mode, determining a target brightness of the display screen module based on the target temperature, determining a second power of the backlight based on the target brightness, and adjusting the power of the backlight to the second power.

The streaming media display mode is a mode capable of displaying an image behind the vehicle, that is, the streaming media display mode shown in the embodiment of fig. 2 described above. In the streaming media display mode, an image of the rear of the vehicle is collected through a camera of the rear of the vehicle, and then the image of the rear of the vehicle collected through the camera is displayed through a display screen module, so that a user can observe the condition of the rear of the vehicle.

The start instruction of the streaming media display mode is used for indicating to start the streaming media display mode, and optionally, the start instruction of the streaming media display mode may be triggered by a user. For example, the user may trigger the start instruction of the streaming media display mode through a click operation, a sliding operation, a somatosensory operation, a voice operation, or the like. As an implementation manner, a switch for starting the streaming media display mode may be configured on the streaming media rearview mirror, and when a user clicks the switch, a start instruction for the streaming media display mode may be triggered.

The target brightness is larger than the rated brightness of the display screen module, and the rated brightness is matched with the current environment of the streaming media rearview mirror. At present, the streaming media rearview mirrors all have a brightness self-adaptation function, that is, the brightness of the streaming media rearview mirrors can be self-adaptively adjusted according to the environment, so as to provide a user with proper display brightness. In this case, the rated brightness may be the brightness determined according to the current environment where the streaming media rearview mirror is located after being started. When the streaming media rearview mirror does not have the brightness self-adapting function, the rated brightness can be the default brightness when the streaming media rearview mirror starts.

The second power is larger than the power of the backlight lamp of the display screen module at rated brightness.

In this case, when the user needs to forcibly turn on the streaming media display mode, the display screen module does not perform normal brightness, but adopts higher brightness to accelerate heating, that is, the purpose of heating the streaming media rearview mirror is achieved by increasing the brightness of the display screen module. Therefore, the temperature of the streaming media rearview mirror can be raised, and the requirement of a user on the streaming media display mode can be met, so that the user experience can be improved.

The operation of determining the target brightness of the display screen module based on the target temperature may be that the target brightness of the display screen module is obtained from the first corresponding relationship based on the target temperature.

The first corresponding relation is the corresponding relation between the temperature of the rearview mirror and the brightness of the display screen module. The first corresponding relation comprises a plurality of temperatures and a plurality of brightnesses, wherein the temperatures and the brightnesses are in one-to-one correspondence, namely, for any one of the temperatures, each temperature corresponds to one brightness.

For example, table 1 below is an example of the first correspondence relationship, see table 1, in which a plurality of temperatures and a plurality of brightnesses are included in table 1. The plurality of temperatures are different temperature environments where the display screen module is located, and the plurality of brightnesses are the brightnesses which are required to be displayed under different temperature environments in order to enable the streaming media rearview mirror to heat the display screen module. For example, the target temperature of the streaming media rearview mirror is-25 ℃, and the target brightness of the display screen module is rated brightness +50nit (nit) can be obtained from the first corresponding relation shown in the following table 1.

TABLE 1

Temperature (temperature)	Brightness of light
		-30°C	Maximum brightness (e.g. 500 nit)
-25°C	Rated brightness +50nit
		-20°C	Rated brightness +30nit
-10°C	Rated brightness (e.g., 300 nit)

The embodiment of the present application will be described by taking table 1 as an example only to illustrate the first correspondence relationship, and is not limited to the embodiment of the present application.

In the first correspondence, the lower the temperature of the streaming rearview mirror, the more severe the smear of the streaming rearview mirror, and the higher the brightness corresponding to the first correspondence may be set so as to raise the temperature as soon as possible by highlighting. When the temperature of the streaming media rearview mirror is low, the smear is not obvious at the moment, and the temperature can be raised by slightly brightening on the basis of rated brightness.

Therefore, the brightness of the display screen module is determined according to the temperature of the streaming media rearview mirror, so that the temperature of the streaming media rearview mirror is ensured to be raised, and meanwhile, the electric energy is saved.

The operation of determining the second power of the backlight based on the target brightness may be determining a required luminous flux based on the target brightness and a screen area of the display screen module, obtaining a light efficiency of the backlight, and dividing the required luminous flux by the light efficiency of the backlight to obtain the second power of the backlight.

The second power of the backlight is the power required by the display screen module to reach the target brightness.

For example, the target brightness is 500nit, the screen area of the display screen module is 0.01m ², and the light efficiency of the backlight is 50.

The required luminous flux is 500 x 0.01=5 and the subsequent calculation yields a second power of the backlight of 5/50=0.1W (watts).

Optionally, in the temperature rising process of the rearview mirror, reminding information can be output in a superimposed mode on a preset picture so as to remind a user that the temperature of the rearview mirror is too low at present, and display can be restored later.

It should be noted that, after step 402, the following operation may be further performed, where the target time period for the streaming rearview mirror to rise from the target temperature to the second temperature threshold is determined based on the target temperature, and the streaming rearview mirror is controlled to highlight the target reminding information on the preset screen.

The second temperature threshold value can be preset, and the second temperature threshold value can be set larger, so that the problem of smear cannot occur after the temperature of the streaming media rearview mirror rises to the second temperature threshold value. In an embodiment of the application, the second temperature threshold is greater than or equal to the first temperature threshold. For example, while the first temperature threshold may be set at-12 ℃, the second temperature threshold may be set at-10 ℃.

The target reminding information comprises target duration or target temperature and target duration.

In this case, the time for the streaming media rearview mirror to return to the normal temperature can be displayed in the heating process, or the low temperature of the streaming media rearview mirror and the time for the streaming media rearview mirror to return to the normal temperature can be displayed. Therefore, the user can know how long the streaming media rearview mirror can be restored to the normal temperature, and the streaming media display mode can be used after how long, so that the user experience is improved.

In addition, as the light transmittance of the dimming glass is lower after the power is off, the highlighted bright characters can pass through the dimming glass, but the black background with darker color is not easy to penetrate, so that the target reminding information can be highlighted on the preset picture. Therefore, the target reminding information is highlighted on the preset picture by controlling the streaming media rearview mirror, so that a user can clearly see the displayed target reminding information.

The operation of determining the target time length of the streaming media rearview mirror from the target temperature to the second temperature threshold based on the target temperature may be that the target time length is determined from the second corresponding relation based on the target temperature.

The second corresponding relation is a corresponding relation between the temperature of the streaming media rearview mirror and the temperature recovery time length, namely the time length of the streaming media rearview mirror from different temperatures to a second temperature threshold value. The second corresponding relation comprises a plurality of temperatures and a plurality of time periods, wherein the plurality of temperatures refer to different temperature environments where the streaming media rearview mirror is located, and the plurality of time periods refer to time periods when the streaming media rearview mirror is recovered from the corresponding low temperature to the second temperature threshold value. The plurality of temperatures are in one-to-one correspondence with the plurality of time durations, that is, any one of the plurality of temperatures has a time duration corresponding to the temperature.

In the embodiment of the present application, the second corresponding relationship may be obtained by calibration in advance. That is, a technician may control the streaming media rearview mirror to be in different temperature environments in an experimental manner, and execute the operation in the step 402 at different temperatures to heat the streaming media rearview mirror, and record the time period when the streaming media rearview mirror is raised from different temperatures to the second temperature threshold, so as to obtain the second corresponding relationship.

For example, table 2 below is an example of the second correspondence, see table 2, including a plurality of temperatures and a plurality of durations in table 2. Wherein the plurality of temperatures and the plurality of time durations are in one-to-one correspondence. For example, the target temperature of the streaming rearview mirror is-25 ℃, and the target duration is 12 minutes from the second correspondence shown in the following table 2.

TABLE 2

Temperature (temperature)	Duration of temperature recovery
		-30°C	15min
-2°C	12min
		-20°C	8min
......	......

The embodiment of the present application will be described by taking the table 2 as an example only to illustrate the second correspondence relationship, and is not limited to the embodiment of the present application.

Optionally, the streaming media rearview mirror may be controlled to display the target reminding information within the display duration.

The display duration can be preset, and the display duration can be set larger.

Under the condition, the target reminding information is displayed in the display time by controlling the streaming media rearview mirror, so that the user can see the target reminding information.

In the embodiment of the present application, after the streaming media rearview mirror is controlled to highlight the target reminding information on the preset screen, the following steps (1) - (2) may be further executed in the process of heating the streaming media rearview mirror.

(1) And detecting the temperature of the streaming media rearview mirror in the process that the streaming media rearview mirror is increased from the target temperature to the second temperature threshold.

In the process that the streaming media rearview mirror is raised from the target temperature to the second temperature threshold value, the temperature of the streaming media rearview mirror can be always detected through the temperature sensor so as to acquire the real-time temperature in the temperature raising process, and whether the temperature of the streaming media rearview mirror is recovered to the normal temperature is determined according to the real-time temperature.

Optionally, the operation of the step (1) may be that the temperature of the streaming media rearview mirror is detected every preset time period during the process that the streaming media rearview mirror is raised from the target temperature to the second temperature threshold.

The preset time period can be preset, and the preset time period can be set to be far smaller than the target time period. For example, the target time period is 10 minutes, and the preset time period may be set to 10 seconds.

(2) And/or displaying a temperature rising progress bar based on a temperature ratio between the detected temperature of the streaming media rearview mirror and a second temperature threshold.

The temperature rising progress bar is used for indicating the temperature rising progress of the streaming media rearview mirror.

In the step (2), the detected temperature of the streaming media rearview mirror is displayed, so that a user can know the real-time temperature of the streaming media rearview mirror in time in the process of heating the streaming media rearview mirror, and the user experience is improved. In addition, through the temperature rising progress bar, the user can know the temperature rising progress of the streaming media rearview mirror in time, so that the user experience is improved.

Alternatively, the detected temperature of the streaming media rearview mirror may be displayed by means of an alarm prompt or a temperature icon.

For example, the detected temperature of the streaming media rearview mirror can be displayed in a blinking manner at the target frequency, so that a user can pay more attention to the real-time temperature of the streaming media rearview mirror, the real-time temperature of the streaming media rearview mirror can be obtained more timely, and further user experience is improved.

For example, fig. 5 is an interface schematic diagram of a display screen of a streaming media rearview mirror according to an embodiment of the present application. Referring to fig. 5, fig. 5 includes a streaming rearview mirror 501, wherein the streaming rearview mirror 501 includes a temperature display area 502 and a temperature rising progress bar 503, and the temperature display area 502 is used for displaying the detected temperature of the streaming rearview mirror. Therefore, the user can know the temperature rising progress of the current streaming media rearview mirror and the real-time temperature of the streaming media rearview mirror by seeing the temperature and the temperature rising progress bar displayed on the display screen.

Optionally, a time duration countdown may also be displayed during the rise in the temperature of the streaming media rearview mirror.

The time length countdown is used for indicating how long the temperature of the streaming media rearview mirror remains to be restored to the normal temperature, namely, the remaining restoration time length of the temperature of the streaming media rearview mirror.

In this case, by counting down the display duration, the user can more intuitively know how long the temperature of the streaming rearview mirror can be raised to the normal temperature after how long, so that the streaming display mode of the streaming rearview mirror can be used after how long. In addition, because the user pays more attention to the time factor relative to the temperature, the user requirement can be met through displaying the time length countdown, and therefore the user experience is improved.

It should be noted that, through the steps 401 and 402, the backlight can emit heat to heat the streaming rearview mirror, so that the temperature of the streaming rearview mirror is recovered to the normal temperature. In the embodiment of the application, after the temperature of the streaming media rearview mirror is recovered to the normal temperature, the streaming media rearview mirror can be controlled to start the streaming media display mode.

Specifically, under the condition that the temperature of the streaming media rearview mirror rises to a second temperature threshold, the display screen module is controlled to display a target picture, the light transmittance of the dimming glass is adjusted to be the second light transmittance, and the reflectivity of the dimming glass is adjusted to be the second reflectivity.

The target picture is a picture acquired by a camera at the rear of the vehicle.

The second light transmittance is the maximum light transmittance of the light-adjusting glass, and the second reflectivity is the minimum reflectivity of the light-adjusting glass.

In this case, the control display module displays the image captured by the camera behind the vehicle. The light-adjusting glass in the reflector mode has the highest reflectivity and the lowest light transmittance, so that the image displayed by the display screen module cannot be transmitted. In order to transmit the picture displayed by the display screen module, the reflectivity of the light-adjusting glass can be adjusted to the lowest and the light transmittance of the light-adjusting glass can be adjusted to the highest, namely, the light transmittance of the light-adjusting glass is adjusted to the second light transmittance, and the reflectivity is adjusted to the second reflectivity.

It should be noted that, in the embodiment of the present application, power may be supplied to the display screen module, so that the light transmittance of the dimming glass is the highest, and the reflectivity is the lowest, that is, the streaming media display mode is turned on.

For easy understanding, an exemplary description will be made of a temperature rising method of a streaming media rearview mirror according to an embodiment of the present application with reference to fig. 6. Fig. 6 is a flowchart of another temperature rising method of a streaming media rearview mirror according to an embodiment of the application. Referring to fig. 6, the following steps 601-609 are included in fig. 6.

And 601, acquiring the target temperature of the streaming media rearview mirror.

Step 602, determining whether the target temperature is less than a first temperature threshold. And executing a step 603 when the target temperature is smaller than the first temperature threshold value, and continuously maintaining the current working mode when the target temperature is larger than or equal to the first temperature threshold value.

And 603, controlling the streaming media rearview mirror to start a mirror mode.

Step 604, power of the backlight is increased, and the display screen module is controlled to display a preset picture.

And 605, highlighting the target reminding information on a preset picture.

Step 606, detecting the temperature of the streaming media rearview mirror in the process of heating the streaming media rearview mirror.

Step 607, determine whether the temperature of the streaming media rearview mirror reaches a second temperature threshold. If the temperature of the streaming mirror reaches the second temperature threshold, step 609 is performed, and if the temperature of the streaming mirror does not reach the second temperature threshold, step 608 is performed.

Step 608, displaying the temperature of the streaming media rearview mirror and/or displaying a temperature rising progress bar.

Step 609, controlling the streaming media rearview mirror to start a streaming media display mode.

In an embodiment of the application, the streaming media rearview mirror comprises a display screen module, and the display screen module comprises a backlight. When the streaming media rearview mirror controller detects that the streaming media rearview mirror is in a preset temperature environment, the streaming media rearview mirror controller can firstly control the streaming media rearview mirror to start a reflecting mirror mode, wherein the reflecting mirror mode is a mode of reflecting the environment behind a vehicle through an optical reflection principle, namely when the streaming media rearview mirror has a low-temperature smear problem, a user can observe the reflected environment behind the vehicle in the reflecting mirror mode. And then, the power of the backlight is increased, and the display screen module is controlled to display a preset picture. Since the brightness of the backlight is higher after the power of the backlight is increased, the light of the backlight is transmitted through the display module to affect the normal use of the reflector mode. Therefore, the power of the backlight lamp can be increased, and the display screen module can be controlled to display a preset picture, such as a pure black picture. Therefore, when the temperature of the streaming media rearview mirror is raised by the heat emitted by the backlight lamp, the light emitted by the backlight lamp is shielded by the preset picture, and the temperature of the streaming media rearview mirror is raised by the heat emitted by the backlight lamp under the condition that the normal use of the rearview mirror by a user is not influenced. Therefore, the problem of smear of the streaming media rearview mirror in a special temperature environment can be solved, and the user experience is improved.
