The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure.

Fig. 1 is a flowchart illustrating a refresh rate adjustment method applied to a terminal according to an exemplary embodiment, where the refresh rate adjustment method includes the following steps, as shown in fig. 1.
In step 101, technology type information of a screen in the terminal, which is one of screens of different technology types adapted to the terminal, is read.
In step 102, a matching refresh rate corresponding to the technology type information is determined, the technology type information of screens of different technology types corresponding to different matching refresh rates.
In step 103, when the current refresh rate of the screen is not suitable for the matching refresh rate, the current refresh rate is adjusted to the matching refresh rate.
In summary, according to the refresh rate adjustment method provided by the present disclosure, by reading the technical type information of the screen in the terminal, the screen is one of the screens of different technical types adapted to the terminal; determining a matching refresh rate corresponding to the technology type information, wherein the technology type information of screens of different technology types corresponds to different matching refresh rates; when the current refresh rate of the screen is not suitable for the matching refresh rate, the current refresh rate is adjusted to the matching refresh rate, different lowest matching refresh rates can be set for screens of different technical types adapted to the terminal, and then the matching refresh rate matched with the screen actually configured in the terminal is read.
Fig. 2 is a flowchart illustrating a refresh rate adjustment method according to another exemplary embodiment, where the refresh rate adjustment method is applied to a terminal, and as shown in fig. 2, the refresh rate adjustment method takes an example that a current refresh rate of a screen is adjusted to a matching refresh rate, and the matching refresh rate is lower than the current refresh rate, and the refresh rate adjustment method includes the following steps.
In step 201, detecting whether valid data received within a predetermined time period changes, the valid data being data displayed on a screen; when the valid data received within the predetermined time period does not change, the execution of step 202 is triggered.
The effective data refers to image frames displayed in a screen, and one set of effective data is one image frame. The valid data is cached in the display buffer, and the valid data cached in the display buffer in the embodiment is periodically refreshed at a preset refresh rate. That is, the valid data of the screen display is periodically refreshed to the next set of the same or different valid data. The refresh rate may also be referred to as a frame rate, and refers to a frequency of refreshing the image frame.
When the effective data received by the terminal within the preset time length is not changed, the effective data received by the terminal within the preset time length is the same, the effective data displayed after refreshing is the same as the effective data displayed before refreshing, and the terminal can reduce the refreshing rate of the screen so as to save the access power consumption of the memory, the transmission power consumption of the data, the refreshing power consumption of the screen and the like. For example, the refresh rate of the terminal is reduced from 60Hz to 50Hz, and at this time, the terminal changes from displaying 60 image frames for 1 second to displaying 50 image frames for 1 second.
In a possible implementation scenario, the terminal is switched from a dynamic scenario to a static scenario, for example, when the terminal is playing a video originally, a higher refresh rate is required, and when a user triggers a control for pausing the playing, the terminal displays a playing picture during pausing, and a lower refresh rate is required at this time. Alternatively, in another possible implementation scenario, the terminal is in a static scenario, e.g., the terminal reads an e-book, browses a web page, etc., where a lower refresh rate is required.
In step 202, technology type information of a screen in the terminal, which is one of screens of different technology types adapted to the terminal, is read.
When the reduced refresh rate is determined, if the refresh rate is set too low, the screen flickers; if the refresh rate is set to be relatively high, the power consumption of the screen is high, and therefore, the terminal needs to determine the refresh rate according to the technical type of the screen.
The technology type information is used to describe a Thin Film Transistor (TFT) technology for implementing the screen, where the TFT technology may include a Low Temperature Polysilicon (LTPS) technology, a α silicon technology, an Indium Gallium Zinc Oxide (IGZO) technology, and the like.
One type of terminal may be adapted to FHD (Full High Definition) screens of different technology types, such as LTPS (Low Temperature polysilicon) type, α silicon type, IGZO (indium gallium Zinc Oxide) type, etc. therefore, when producing one type of terminal, a manufacturer may configure a part of terminals with LTPS type screens, another part of terminals with α silicon type screens, and the rest of terminals with IGZO type screens.
Generally, when configuring a screen for a terminal, technology type information of the screen may be written in the terminal, and the terminal may directly read the technology type information, which indicates a technology type to which the screen belongs.
In step 203, a matching refresh rate corresponding to the technology type information is determined, and the technology type information of screens of different technology types corresponds to different matching refresh rates.
The determining of the matching refresh rate corresponding to the technology type information includes: and determining leakage current corresponding to the technical type information, and determining a matching refresh rate according to the leakage current, wherein the leakage current and the matching refresh rate have positive correlation.
Since the TFT technology used by the screens of different technology types is different, the leakage current corresponding to the screens of different technology types is different. The leakage current and the dimming speed of the screen are in a positive correlation relationship, namely, the larger the leakage current is, the faster the screen becomes dark; the smaller the leakage current, the slower the screen darkens.
For ease of understanding, the present embodiment is illustrated with a first terminal and a second terminal. If the leakage current of the first terminal is larger than the leakage current of the second terminal, and the refresh rate of the first terminal and the refresh rate of the second terminal are the same as the brightness of the refreshed screen, if the first group of valid data is refreshed by the first terminal and the second terminal at the same time, the brightness of the screen of the first terminal is smaller than the brightness of the screen of the second terminal before the second group of valid data is refreshed, and after the second group of valid data is refreshed, because the brightness of the refreshed screen is the same, the brightness change of the first terminal before and after the refresh is larger than the brightness change of the second terminal before and after the refresh, and the screen of the first terminal is easy to flicker.
In order to ensure that the screen does not flicker before and after refreshing, a higher matching refresh rate needs to be set for the screen with large leakage current, and a lower matching refresh rate needs to be set for the screen with small leakage current. That is, the leakage current is positively correlated with the matched refresh rate. Therefore, when the leakage currents of the screens of different technology types are different, the corresponding matching refresh rates are also different. The matching refresh rate is the lowest refresh rate that ensures that the screen does not flicker.
When the method is implemented, the matching refresh rates corresponding to the screens of different technical types can be determined according to a large number of experiments, so that when the screen refreshes the image frames at the matching refresh rate, the flicker value is smaller than-30 dB, and the flicker value is smaller than-30 dB, so that the screen does not flicker, and the display quality of the image frames is ensured.
Of course, the adjustment can be performed on the basis of the numerical value obtained through the experiment, and the adjusted numerical value is used as the final matching refresh rate, so that the practicability during batch production is ensured. For example, if the value obtained by the experiment is 50Hz, and can be adjusted up to 5% on the basis of the value, the matching refresh rate obtained is 50 × 52.5Hz (1+ 5%). The floating percentage can be set and modified, and the embodiment is not limited.
In step 204, the current refresh rate is adjusted to the matching refresh rate when the current refresh rate of the screen is not compatible with the matching refresh rate.
This embodiment provides two implementations of adjusting the refresh rate, which are described below.
In a first implementation manner, a first transmission rate is determined according to a matching refresh rate, and a current second transmission rate is adjusted to the first transmission rate, where the first transmission rate is a transmission rate of valid data displayed on a screen, and the first transmission rate is lower than the second transmission rate, and the second transmission rate corresponds to the current refresh rate.
Since the terminal will not display until it receives the complete set of valid data, the refresh rate can be reduced by reducing the data transmission rate. For example, the current refresh rate is 60Hz, and the data transmission rate corresponding to 60Hz is aKb/s, and if the matching refresh rate is 30Hz, the data transmission rate corresponding to 30Hz is calculated to be a/2 Kb/s.
In a second implementation, the data is transmitted at a current second transmission rate, the data includes at least two sets of valid data, and at least one set of invalid data is inserted between the at least two sets of valid data, the valid data is data displayed in the screen, the invalid data is data not displayed in the screen, and the second transmission rate corresponds to the current refresh rate.
The terminal only uses the received valid data to refresh the currently displayed valid data, so that invalid data can be inserted between the valid data, and when the terminal receives the invalid data, the invalid data is not used to refresh the valid data, so that the refresh rate is reduced.
Wherein the amount of invalid data inserted is related to the matching refresh rate and the current refresh rate. For example, the current refresh rate is 60Hz, at this time, 60 sets of valid data need to be transmitted within 1 second, if the matched refresh rate is 30Hz, at this time, 30 sets of valid data need to be transmitted within 1 second, and invalid data of 30 can be inserted within the 1 second; if the matching refresh rate is 50Hz, 50 sets of valid data need to be transmitted within 1 second, and 10 sets of invalid data can be inserted within the 1 second.
It should be noted that invalid data may be inserted evenly between valid data. For example, assuming that 30 sets of valid data and 30 sets of invalid data need to be transmitted within 1 second, one set of invalid data may be inserted between every two sets of valid data; assuming that 50 sets of valid data and 10 sets of invalid data need to be transmitted within 1 second, one set of invalid data may be inserted between every five sets of valid data. Of course, the invalid data may also be inserted in other ways, and this embodiment is not limited.
In this embodiment, the idle time between two sets of valid data is referred to as porch, and the second implementation manner may be referred to as increasing the porch value.
In step 205, when valid data different from the valid data displayed in the screen is received, the matching refresh rate is adjusted to the current refresh rate.
When the received valid data is different from the valid data displayed in the screen, the terminal needs to adjust the refresh rate up. The process of adjusting the matching refresh rate to the current refresh rate by the terminal is opposite to the process of adjusting the current refresh rate to the matching refresh rate, for example, the first transmission rate is adjusted to the second transmission rate, or the data is transmitted at the second transmission rate and includes only valid data, which is not described in detail in this embodiment.
In summary, according to the refresh rate adjustment method provided by the present disclosure, by reading the technical type information of the screen in the terminal, the screen is one of the screens of different technical types adapted to the terminal; determining a matching refresh rate corresponding to the technology type information, wherein the technology type information of screens of different technology types corresponds to different matching refresh rates; when the current refresh rate of the screen is not suitable for the matching refresh rate, the current refresh rate is adjusted to the matching refresh rate, different lowest matching refresh rates can be set for screens of different technical types adapted to the terminal, and then the matching refresh rate matched with the screen actually configured in the terminal is read.
In addition, the matching refresh rate is determined according to the leakage current, and the brightness change of the screen can be accurately determined according to the leakage current, so that the matching refresh rate is determined according to the brightness change, and the problem of screen flicker caused by large brightness change can be solved.
