Display control is performed on the display device according to the target display parameter.

Based on the above-mentioned display device, the display control method of this embodiment will be described in detail below with reference to the schematic flowchart shown in FIG. 1 . The method may include the following steps:

Step S10: Obtain environmental information of the environment where the display device is located.

Specifically, the display device may be a TV, a smart screen, a mobile phone, etc. This embodiment takes a TV as an example for description. The acquisition method can be acquired by using sensors, or by processing the acquired data through a dedicated application program. The environmental information can be one or more of season, time, weather, temperature, brightness, etc. Correspondingly, the season and time can be obtained through the built-in time application, and the weather can be obtained through the weather application. It can be obtained directly through the built-in sensor of the TV, and the specific environmental information can be set according to the actual situation. Among them, the way of directly collecting environmental information can obtain more real and accurate data, which can better represent the real environment of the display device; the way of obtaining through the application program can obtain more comprehensive and real-time data, and also The data of the future period can be obtained. For example, in the weather application, the specific time of sunset at the location is generally indicated according to the geographical location. If the current time has not yet sunset, but the time set by the system has already sunset, it will be the same as the sunset. There are actual differences. Therefore, the use of applications to obtain environmental information can be more realistic, more accurate, and more suitable for the real environment; moreover, it can also prepare in advance for the subsequent display control of the display device, that is, in advance. The weather, time and other environmental information of the future time are obtained, so as to obtain the target display parameters of the future time, so that when the future time arrives, the display control can be performed directly with the target display parameters, so as to quickly respond to environmental changes.

Step S30: Searching for a preset adjustment parameter corresponding to the environment information according to a preset lookup table; wherein the preset lookup table includes a correspondence between the environment information and the preset adjustment parameter.

Specifically, a preset look-up table (look-up-table, LUT for short) can be set when the display device is produced, and the preset look-up table includes the correspondence between environmental information and preset adjustment parameters. When the environmental information has only one environmental parameter, the corresponding relationship between the environmental parameter and the preset adjustment parameter can be directly set. When the environmental information has multiple environmental parameters, different combinations of the multiple environmental parameters and the preset adjustment parameter can be set. corresponding relationship. Wherein, the preset adjustment parameter may be one or multiple, and is specifically set according to the display parameter that needs to be adjusted. For example, when it is necessary to adjust the gray-scale brightness of a display device, since the gray-scale and gray-scale brightness change in a curve, the value of the gamma curve, that is, the gamma value, can be directly determined. Correspondingly, the gamma value can be adjusted to determine Different gamma curves enable the display device to control grayscale and grayscale brightness based on the gamma curve for environmental information. The preset adjustment parameter at this time can be set as the amount of change in the gamma value, such as a gain coefficient. When it is necessary to adjust display parameters such as gray-scale brightness, backlight brightness, color temperature, etc. at the same time, preset adjustment parameters including gain coefficient, preset brightness value, preset color temperature value, etc. can be correspondingly set.

Step S50: Determine to obtain target adjustment parameters according to the preset adjustment parameters.

Specifically, the preset adjustment parameter may be one or more than one, and the corresponding obtained target adjustment parameter may also be one or more, which is specifically set according to the display parameter to be adjusted. When the grayscale brightness of the display device needs to be adjusted, the preset adjustment parameter is set as the gain coefficient. At this time, the target adjustment parameter includes the target gamma value. The gamma value is calculated; when it is necessary to adjust display parameters such as grayscale brightness, backlight brightness, and color temperature at the same time, the preset adjustment parameters are set to multiple parameters such as gain coefficient, preset brightness value, and preset color temperature value. The target adjustment parameters may include a target gamma value, a target luminance value, and a target color temperature value.

Step S60: Adjust the real-time display parameters of the display device according to the target adjustment parameters to obtain target display parameters.

Specifically, there may be one display parameter, or multiple display parameters. The adjustment of the display parameter may be to increase or decrease the value, so as to obtain the target value as the target display parameter. For example, the brightness and color temperature of the backlight can be adjusted. Specifically, by comparing The current backlight brightness and the target brightness value, determine whether the brightness value needs to be increased or decreased correspondingly to obtain the target backlight brightness, and by comparing the current color temperature and the target color temperature value, determine whether to increase or decrease the color temperature value correspondingly, and obtain the target color temperature, here The target adjustment parameters include the target brightness value and the target color temperature value. The current brightness and current color temperature can be obtained by the display device before this step, that is, the display device can obtain the real-time display parameters including the real-time backlight brightness and real-time color temperature in real time, here The target display parameters include target backlight brightness and target color temperature. The adjustment of the display parameters may also be to switch the display parameters of the display device based on the target adjustment parameters. For example, the gamma curve of the display device may be switched based on the target gamma value to obtain the target gamma curve. The gamma value and the preset gamma curve are used to determine the preset gamma curve corresponding to the target gamma value, and the preset gamma curve is used to replace the real-time gamma curve of the display device to obtain the target display parameters, where the The target adjustment parameters include target gamma values, and the target display parameters include target gamma curves.

Step S80: Perform display control on the display device according to the target display parameter.

Specifically, after obtaining the target display parameters in step S60, the display device may perform display control according to the target display parameters, that is, adjust the display effect of the display screen of the display device, including cool or warm tones, bright or dark, Different display effects such as bright or soft, so as to achieve the purpose of adjusting the effect of the display screen according to the environment where the display device is located, so as to meet the different needs of users in different environments and increase the user experience.

In the display control method provided in this embodiment, after obtaining the environmental information of the environment where the display device is located, according to a preset look-up table, the preset adjustment parameters corresponding to the environment information are searched, and the target adjustment parameters are determined according to the preset adjustment parameters, Then adjust the parameters according to the target, adjust the real-time display parameters of the display device, obtain the target display parameters, and finally control the display device according to the target display parameters. Effect. When the environment in which the display device is located changes the user's needs and the user's own perception, the display device automatically adjusts the display parameters to show different display effects, which improves the user's viewing experience and allows users to have a better understanding of TV and other display devices. Better user experience.

Embodiment 2

Based on the same inventive concept, a second embodiment of the display control method of the present invention is proposed. The display control method is applied to a display device. In this embodiment, a television set is used as a display device for illustration.

The display control method of this embodiment will be described in detail below. The method may include the following steps:

Step S10: Obtain environmental information of the environment where the display device is located.

Specifically, the environmental information includes at least one of season, weather and time.

Because the main factors affecting people's perception of display devices are the climate changes caused by the change of seasons in spring, summer, autumn and winter, the temperature changes caused by weather changes such as cloudy, sunny, rainy and snow, and the lighting changes caused by the time replacement of morning, middle and night, etc. In different time periods, different weathers and different seasons, people will have different requirements for the display screen of the display device. For example, on a snowy night in winter, they may want the display screen of the display device to be darker and warmer, and clearer in winter. During the day, you may want to display a brighter warm color on the display screen of the device. For example, on a sunny day in summer, you may want to display a brighter cool color on the display screen of the device. On a rainy night in summer, you may want to The display screen of the display device is dark and cool.

In the specific implementation process, only seasonal information, only weather information, or only time information may be acquired, or these information may be arbitrarily combined. Other environmental information can also be added or replaced with other environmental information, such as temperature, humidity, brightness, etc., and even the other environmental information here can be combined with any one or more of the above environmental information, depending on the actual situation. set up. In this embodiment, winter-sunny day-18 o'clock and summer-sunny day-12 o'clock are taken as examples for illustration.

Here, the environmental information is set to season, weather, and time. Compared with the way of directly setting environmental information such as temperature, humidity, and brightness, it combines the characteristics of season and weather, which have a more obvious impact on the user's perception. It can be close to the user's perceived needs, so that the display effect obtained by subsequent display control is more satisfactory to the user.

Further, step S10 may include:

Step S11: Generate a display adjustment instruction when a display adjustment start operation performed on the display device is detected.

Specifically, a corresponding startup button or startup menu can be set on the display device, and the user can actively enable the display adjustment function, that is, the display adjustment startup operation is performed through the startup button or startup menu on the display device, and then the display device is based on the display device. The operation generates display adjustment instructions. The display device can also automatically generate a display adjustment instruction according to the set conditions when the conditions are satisfied.

Based on the situation of this embodiment, the display adjustment start operation on the TV can be selected from the TV menu through the remote control, or can be selected from the TV menu through the buttons set on the TV. After selecting the corresponding start button or start menu, The display device can generate display adjustment instructions.

Step S12: In response to the display adjustment instruction, obtain environmental information of the environment where the display device is located.

Specifically, in response to the display adjustment instruction, the display device obtains the temperature, humidity and brightness of the environment in which it is located through built-in sensors, or obtains the season, weather and time of the environment in which it is located through other applications. Built-in sensors can include temperature sensors, humidity sensors and brightness sensors, etc. Other applications can include weather APP and clock APP, which can be directly connected to the Internet to obtain real-time data or future forecast data.

Further, step S10 may also include:

Step S13: Acquire environmental information of the environment in which the display device is located through an application program of the display device and/or a built-in sensor of the display device.

The display device obtains environmental information through other applications and/or built-in sensors, and the acquisition method is mainly set according to the content of the environmental information. For example, when the environmental information includes weather and temperature, the weather can be obtained through the weather APP, and the built-in temperature sensor to get the temperature.

Step S30: Searching for a preset adjustment parameter corresponding to the environment information according to a preset lookup table; wherein the preset lookup table includes a correspondence between the environment information and the preset adjustment parameter.

Specifically, the preset adjustment parameters corresponding to the environmental information are searched in a preset look-up table; wherein, the preset look-up table includes season, weather, time or a combination of season, weather and time and the preset adjustment parameters respectively. Adjust the correspondence between parameters. When there is one piece of environmental information, the information is directly used as the search condition, and the corresponding preset adjustment parameters are searched in the preset lookup table; when there are multiple pieces of environmental information, different combinations of the multiple pieces of information are used as the search condition , search in the preset lookup table to find preset adjustment parameters corresponding to different combinations. The preset adjustment parameter may be a direct variable of a display parameter or an indirect variable, for example, a color temperature value of a color temperature, or a gain coefficient of a gamma value of a gamma curve.

Step S50: Determine target adjustment parameters according to the preset adjustment parameters.

When the preset adjustment parameter is the direct variable of the display parameter, the preset adjustment parameter can be directly used as the target adjustment parameter; when the preset adjustment parameter is the indirect variable of the display parameter, the corresponding calculation can be performed based on the preset adjustment parameter, The obtained value is used as the target adjustment parameter.

In one embodiment, before step S50, the method may further include:

Step S40: acquiring real-time attribute parameters of the display device;

Correspondingly, the step S50 may include:

Step S51: Determine target adjustment parameters according to the preset adjustment parameters and the real-time attribute parameters.

Specifically, the preset adjustment parameter may include a gain coefficient, and the real-time attribute parameter may include a real-time gamma value; in this case, step S51 may include:

Step S51.1: Obtain a target adjustment parameter according to the gain coefficient and the real-time gamma value; the target adjustment parameter includes a target gamma value.

At present, the gamma value of many display devices is fixed, and the gray-scale brightness is directly adjusted by the gamma curve represented by the gamma value. In this embodiment, a plurality of different gamma values can be set for the display device, each Gamma values represent different gamma curves. As shown in the schematic diagram of the gamma curve as shown in FIG. 3 , in the figure, the horizontal axis represents 0 to 255 gray levels, and the vertical axis represents the brightness ratio. There are four gamma curves in the graph, each with a different gamma value. Because the human eye's perception of brightness is not proportional to physical power, but a power function, and the exponent of this function is the gamma value (Gamma). The smaller the gamma value, the brighter the picture. The gamma curve represented by Gamma1 in the figure is the brightest. The larger the gamma value, the darker the picture. The gamma curve represented by Gamma4 in the figure is the darkest. The brighter the gamma curve, the better the visibility of the bright part in the display screen of the display device, that is, the contrast between the brighter area and the darker area in the display screen will be larger. So that the subjective feeling of the human eye is brighter.

When the display parameter includes a gamma curve, to obtain the target display parameter, that is, the target gamma curve, a gamma value representing the gamma curve needs to be obtained. Therefore, the target adjustment parameter in this embodiment is the target gamma value, and the gamma value is the target gamma value. The value is generally increased according to a certain law, so the preset adjustment parameter here is the gain coefficient.

The display device obtains its own real-time gamma value, and then searches for the corresponding preset adjustment parameters in the preset lookup table according to the obtained environmental information, that is, searches for the corresponding gain coefficient, and then compares the real-time gamma value with the gain. Multiply the coefficients to get the target gamma value. For example, if the current gamma value is 2.0, and the found gain coefficient is 1.1, the target gamma value can be obtained after multiplication is 2.2. Further, a corresponding threshold range can also be set for the target gamma value. When the calculated target gamma value exceeds the threshold range, the maximum value of the threshold range is used as the final target gamma value. When the target gamma value is lower than the threshold range, the minimum value of the threshold range is used as the final target gamma value. For example, if the current gamma value is 2.4, and the found gain coefficient is 1.1, the target gamma value is 2.64. Assuming that the set threshold range is 1.8 to 2.6, at this time, take 2.6 as the target gamma value, For another example, if the current gamma value is 2.0, and the found gain coefficient is 0.8, the target gamma value is 1.6, and the range below the set threshold is 1.8-2.6. At this time, 1.8 is used as the target gamma value. value. When the display device cannot set the gamma value due to the limitation of hardware conditions, it is possible to ensure that the adjustment requirements are met as much as possible, and the use of the display device will not be affected.

When the curve that adjusts the image parameter or screen parameter is used as the display parameter, what this method actually adjusts is only the switching of the curve, and the corresponding variables representing different curves can be used as the target adjustment parameter. Correspondingly, the target adjustment parameter can be changed. The regular coefficient is used as the preset adjustment parameter, and the target value can also be used as the preset adjustment parameter. That is to say, the gain coefficient of the gamma value may be used as the preset adjustment parameter here, or the gamma value may be directly used as the preset adjustment parameter.

In another embodiment, the preset adjustment parameter includes a preset brightness value and/or a preset color temperature value, and the target adjustment parameter includes a target brightness value and/or a target color temperature value; step S50 may include:

Step S52: determining the preset brightness value as the target brightness value; and/or

Step S53: Determine the preset color temperature value as the target color temperature value.

Specifically, the preset adjustment parameter can be a specific value or a value range. When the preset adjustment parameter is a specific value, the specific value can be directly determined as the target adjustment parameter. When the preset adjustment parameter is a value range , the range can be used as the range, and the display parameters can be adjusted automatically or manually within this range to ensure the overall display effect of the display screen. Compared with the specific values, the form of the numerical range has a certain degree of customization. Within this range, set it manually according to your own situation.

In this embodiment, when two display parameters of backlight brightness and color temperature of the TV need to be adjusted, the preset adjustment parameters include preset brightness value and preset color temperature value, and the target adjustment parameter includes target brightness value and target color temperature value. After acquiring the environmental information, the display device searches for the corresponding preset adjustment parameter in the preset lookup table based on the environment information or a combination of the environment information, and directly determines the preset adjustment parameter as the target adjustment parameter.

The following is an example of searching for a preset brightness value corresponding to environmental information such as time in a preset lookup table. At present, the screen brightness in the TV, that is, the backlight brightness is generally related to 100, but in the dark environment at night, it is easy to dazzle and make the eyes uncomfortable. Therefore, different backlight brightnesses are correspondingly set for different time points. To achieve this, it is necessary to set the preset brightness value correspondingly according to the time when setting the preset lookup table. As shown in FIG. 4 , the change curve of the preset brightness value with the time point, the horizontal axis is the time point, and the vertical axis is the preset brightness value. The preset brightness value corresponding to the time information, so that the preset brightness value is determined as the target brightness value.

Dynamically adjust the backlight brightness through time information, so that when the brightness is low in the night environment, the screen brightness can be reduced, and when the brightness is high in the daytime environment, the screen brightness can be increased. By adjusting to different brightness in different time periods, it can meet the user's brightness requirements for different time periods.

The following is an example of finding a preset color temperature value corresponding to a combination of environmental information such as season, weather, and time in a preset lookup table. Due to different time periods, different weathers and different seasons, the color temperature itself is different, as shown in Table 1 for the color temperature under different environmental conditions.

Table 1

Environmental situation Reference color temperature (K) morning glow 3000 dusk 4000 direct sunlight in summer 5800 direct sunlight in summer 6700 Direct sunlight in the morning 6000 direct noon sun 6500 cloudy light 6800-7000 cloudy light 7500-8400 sunny light 10000-20000

The setting of the preset color temperature value can be directly set during the production of the display device, and can be set according to actual needs. For example, when the environmental information is only the seasons of spring, summer, autumn and winter or simple weather conditions such as cloudy, sunny, rainy and snowy, the color temperature can be set to 5 intervals (W1~W5), respectively W1<6500K, 6500≤W2<8000K, 8000≤W3＜12000K, 12000≤W4＜15000K, W5≥15000K. Because there are not many combinations of search conditions, the preset adjustment parameters are set as ranges, which is convenient for users to make subsequent custom adjustments within the range. Here, W1 to W5 can be defined as the warmest color, warm color, standard color, cool color, and coolest color in sequence, and correspondingly, the five intervals can be set as preset color temperature values. Then, based on the reference color temperature corresponding to different weather conditions, under the condition of the combination of environmental information corresponding to the high reference color temperature, the preset color temperature value is set to the cool color temperature range, and the color temperature is set in the reverse direction, which can meet the needs of the user when the temperature is cold. You want warm colors in the day, and you want cool colors in hot days.

In another case, when the environmental information includes more refined parameters such as time, due to the increase of search conditions, correspondingly, a specific value can be used as the setting value for each combination of environmental information, which is convenient for subsequent direct Determined as the target adjustment parameter, so as to directly determine the adjustment value, get the target display parameter as soon as possible, and carry out display control.

It should be noted that steps S40 and S51 can be performed together with steps S52 and S53, that is, when the display parameters include gamma curve, backlight brightness and color temperature, the corresponding target gamma value, target brightness value and target color temperature value are obtained respectively.

Step S70: Adjust the display parameters of the display device according to the target adjustment parameters to obtain target display parameters.

In one embodiment, the display parameter includes a gamma curve; before step S70, the method may further include:

Step S61: Acquire preset attribute parameters of the display device, where the preset attribute parameters include at least two preset gamma values;

Step S62: According to the grayscale and brightness of the display device, draw a gamma curve corresponding to the preset attribute parameter to obtain a preset display parameter, where the preset display parameter includes at least two preset gamma curves;

Step S63: Store the preset display parameters.

During the production of the display device, multiple preset gamma values can be set and stored. For example, in this embodiment, four preset gamma values are set, Gamma1=2.0, Gamma2=2.2, Gamma3=2.4, Gamma1=2.6, according to The relationship between the gray scale and the brightness of the display device is drawn to obtain four gamma curves as shown in FIG. 3 , and the display device can subsequently use any gamma curve to automatically adjust the gray scale brightness. Here, the four gamma curves are stored in the display device for subsequent selection and adjustment for environmental information from the four gamma curves.

Further, step S70 may include:

Step S71: According to the target gamma value and the at least two preset gamma curves, determine a preset gamma curve corresponding to the target gamma value to replace the real-time display parameters of the display device, and obtain: target display parameters; the real-time display parameters include a real-time gamma curve, and the target display parameters include a target gamma curve.

After the target gamma value is acquired in step S51, a preset gamma curve corresponding to the target gamma value is selected from the four gamma curves stored in the display device, and then the preset gamma curve of the display device is replaced by the preset gamma curve. Real-time gamma curve, the preset gamma curve is the target gamma curve of the display device. For example, in this embodiment, when the target gamma value is 2.2, it can be confirmed that the second curve in FIG. 3 (Gamma2 represents The gamma curve) is the grayscale adjustment scheme for this display adjustment. The grayscale and grayscale brightness of the display device will be automatically adjusted according to the change of the curve, and the grayscale brightness will be automatically adjusted according to the gamma curve. technology, which will not be repeated here.

In another embodiment, the display parameters include backlight brightness and/or color temperature; before step S70, the method may further include:

Step S64: acquiring real-time display parameters of the display device, where the real-time display parameters include real-time backlight brightness and/or real-time color temperature;

Correspondingly, step S70 may include:

Step S72: obtaining an adjustment value of the display parameter according to the target adjustment parameter and the real-time display parameter;

Step S73: Adjust the real-time display parameters according to the adjustment values to obtain target display parameters, where the target display parameters include target backlight brightness and/or target color temperature.

The display device obtains its own real-time display parameters, and here obtains its own real-time backlight brightness and real-time color temperature. After obtaining the target brightness value and the target color temperature value in step S50, the difference between the target brightness value and the real-time backlight brightness is calculated, that is, the brightness of the backlight. Adjust the value, and then adjust the backlight brightness according to the adjustment value. When the adjustment value is positive, it indicates that the brightness needs to be increased. The increased brightness value is the absolute value of the adjustment value. When the adjustment value is negative, it indicates that The brightness needs to be reduced, and the reduced brightness value is the absolute value of the adjustment value. In the same way, correspondingly calculate the difference between the target color temperature value and the real-time color temperature to obtain the adjustment value of the color temperature, and then increase or decrease the color temperature of the display device according to the adjustment value to obtain the final backlight brightness and color temperature, which is the target. Backlight brightness and target color temperature.

It should be noted that step S71 and steps S64, S72 and S73 can be carried out separately and independently to switch the gamma curve of the display device and adjust the backlight brightness and color temperature of the display device; it can also be carried out simultaneously. , that is, the gamma curve of the display device is switched, the grayscale brightness of the display device is automatically adjusted with the gamma curve, and the backlight brightness and color temperature of the display device are adjusted.

Step S90: Perform display control on the display device according to the target display parameter.

In step S70, the target display parameters are obtained, for example, after obtaining the target gamma curve, the target backlight brightness and the target color temperature, the display device is controlled according to the above parameters, and the display screen is controlled to be displayed with the target display parameters, and the user can see the adjustment after the display.

Under the current screen of Figure 5(a), the above methods are used to adjust the two environmental conditions respectively, and Figure 5 is obtained. (b) and Figure 5(c). Figure 5(b) is the display screen under the first environmental situation, wherein the first environmental situation is winter-sunny day-18 o'clock, and the determined target display parameters include the target gamma curve, the target backlight brightness and the target color temperature. As can be seen from Figure 5(b), the color temperature of the display screen is warm, the backlight brightness is around 80, and the brighter area is slightly brighter, indicating that the gamma value has decreased.
