It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
The embodiment of the application provides a display method which is applied to a terminal. The terminal may be an electronic device such as a mobile phone and a tablet computer, and the specific terminal is not limited in the embodiment of the present application.
It should be noted that, in the embodiments of the present application, the terminal includes a display screen, and the display screen includes a light-transmitting display area and a normal display area. The brightness decay speed of the light-transmitting display area is higher than that of the normal display area.
It will be appreciated that in embodiments of the present application, the display screen may be divided into two regions, a transmissive display region and a normal display region. The light-transmitting display area is actually the display area corresponding to the front camera. The front camera is arranged below the transparent display area, the number of pixels arranged in the transparent display area is small, and the pixel density is low, so that incident light penetrating through gaps among the pixels in the transparent display area can be received by the front camera to form images. Since the transparent display area has fewer pixels and low density, and the normal display area has more pixels and high density, the brightness attenuation speed is higher than that of the normal display area, as shown in fig. 1, which is a contrast graph of brightness attenuation of displaying a pure white picture under the same brightness of the normal display area and the transparent display area.

I.e. uniformity and reliability of the display screen is guaranteed. This is the physical basis for correcting for brightness decay.
Based on the description of the display screen, the display method will be described in detail below.
Fig. 4 is a schematic flowchart of a display method according to an embodiment of the present application. As shown in fig. 4, in the embodiment of the present application, the display method mainly includes the following steps:
s101, under the condition that signal data of a display screen are transmitted to a DDIC of a terminal, the signal data are used for respectively converting a first use duration of a light-transmitting display area and a second use duration of a normal display area under standard brightness.
The Display method provided by the embodiment of the application is applied to a scene that a Display Driver Integrated Circuit (DDIC) of a terminal performs brightness compensation on signal data of a Display screen.
In the embodiment of the application, the display screen includes the light-transmitting display area and the normal display area, so the signal data includes first signal data corresponding to the light-transmitting display area and second signal data corresponding to the normal display area.

Specifically, in the DDIC, at least one first low gray scale luminance used in the light-transmitting display region is obtained according to the first signal data; the using time length of each first low gray scale brightness in the at least one first low gray scale brightness of the light-transmitting display area is obtained, and at least one first historical time length is obtained.
It should be noted that, in the embodiment of the present application, the terminal may continuously monitor the low gray-scale luminance of the transparent display area, so as to be able to obtain each used low gray-scale luminance of the transparent display screen, and determine each used low gray-scale luminance as a first low gray-scale luminance. In addition, the terminal can continuously count the use duration of different low gray scale brightness in the process of historical use of the light-transmitting display area, and each use duration is determined as a first historical duration, so that at least one first historical duration is obtained.

It is understood that, in the embodiment of the present application, the standard brightness may be a preset brightness, and specifically, may be the highest brightness that can be achieved by the display screen. When a user uses the terminal daily, the light-transmitting display area is not always under the standard brightness, and may be under various brightness conditions, so that the historical use duration under different brightness conditions needs to be converted to obtain the use duration under the standard brightness.
It should be noted that, in the embodiment of the present application, the terminal may multiply each of the at least one first historical time duration by a corresponding weighting coefficient of the at least one weighting coefficient to obtain a corresponding one of the first standard time durations, and then add all the at least one first standard time durations to obtain the first usage time duration, that is, convert the usage time duration of the transparent display screen at the standard brightness.
In the embodiment of the application, under the condition that the terminal transmits the signal data of the display screen to the DDIC of the terminal, in the DDIC of the terminal, at least one second historical duration corresponding to at least one second low gray scale brightness is determined according to the second signal data; wherein the at least one second low gray scale luminance is a low gray scale luminance already used in the normal display region; then, converting at least one second historical time length into at least one second standard time length under standard brightness; the sum of the at least one second standard time duration is determined as the first usage time duration.
Specifically, in the DDIC, at least one second low gray-scale luminance used in the normal display area is acquired according to the second signal data; and acquiring the use time of each second low gray scale brightness in the at least one second low gray scale brightness of the normal display area to obtain at least one second historical time.

It should be noted that, in the embodiment of the present application, a manner of converting the first using duration of the transparent display area at the standard brightness by using the first signal data corresponding to the transparent display area by the terminal is completely the same as a manner of converting the second using duration of the normal display area at the standard brightness by using the second signal data corresponding to the normal display area, and details are not repeated here.
S102, determining the brightness difference between the light-transmitting display area and the normal display area based on the brightness attenuation information in the DDIC, the first using time length and the second using time length.
After the first using time length of the light-transmitting display area of the display screen and the second using time length of the normal display area are converted, the terminal determines the brightness difference between the light-transmitting display area and the normal display area based on the brightness attenuation information, the first using time length and the second using time length in the DDIC.
In the embodiment of the application, brightness attenuation information is built in a DDIC of a terminal, first brightness attenuation information corresponding to a first use time length and second brightness attenuation information corresponding to a second use time length are respectively determined from the brightness attenuation information in the DDIC, and then, according to the first brightness attenuation information and the second brightness attenuation information, a brightness difference between a light-transmitting display area and a normal display area is determined.
In the embodiment of the present application, the brightness attenuation information embedded in the DDIC includes brightness attenuation information of the transparent display area and brightness attenuation information of the normal display area, where the brightness attenuation information of the transparent display area is brightness attenuation information corresponding to different use durations of the transparent display area at standard brightness, and the brightness attenuation information of the normal display area is brightness attenuation information corresponding to different use durations of the normal display area at standard brightness. After the terminal obtains the first use duration and the second use duration, the terminal obtains first brightness attenuation information from the brightness attenuation information of the light-transmitting display area and obtains second brightness attenuation information from the brightness attenuation information of the normal display area.
In the embodiment of the present application, the difference between the first luminance attenuation information and the second luminance attenuation information is determined as the luminance difference between the transmissive display area and the normal display area.
Further, after the first brightness attenuation information and the second brightness attenuation information are obtained, the terminal also judges the attenuation degree of the normal display area, and under the condition that the second brightness attenuation information reaches the preset brightness attenuation, the terminal multiplies the gray scale of the normal display area by a coefficient to reduce the brightness of the normal display area, so that more adjustment spaces can be provided for the transparent display area in a high gray scale area, at the moment, the terminal redetermines the brightness difference between the light-transmitting display area and the normal display area, and obtains a new compensation value from the compensation data table according to the redetermined brightness difference to realize the brightness compensation of the light-transmitting display area based on the new compensation value.
S103, according to the brightness difference, a compensation value is determined from a compensation data table in the DDIC.
In the embodiment of the application, the terminal further sets a preset difference threshold, after the terminal determines the brightness difference, the terminal compares the brightness difference with the preset difference threshold, and determines the compensation value from the compensation data table in the DDIC according to the brightness difference when the brightness difference exceeds the preset difference threshold.
In the embodiment of the application, a compensation data table is preset in the DDIC, wherein compensation values corresponding to different brightness differences are stored, and the terminal determines the compensation values corresponding to the brightness differences from the compensation data table.
And S104, compensating the signal data by using the compensation value to obtain compensated signal data, and controlling a display screen to display by using the compensated signal data.
In the embodiment of the application, after the terminal determines the compensation value, the terminal compensates the signal data of the display screen by using the compensation value to obtain compensated signal data, and then controls the display screen to display by using the compensated signal data.
Specifically, the compensation value is used for compensating first signal data corresponding to the light-transmitting display area to obtain compensated first signal data, then the DDIC of the terminal outputs the compensated first signal data, and the compensated first signal data and second signal data of the normal display area are used for controlling the display screen to display.
It should be noted that, in this embodiment of the application, the DDIC of the terminal adds the compensation value to the voltage of the first signal data to assign the high gray scale current value to the low gray scale, so as to implement the process of brightness compensation on the transparent display area, specifically, the gamma curve of the transparent display area and the gamma curve of the normal display area are stored in the FLASH memory, the gamma curves represent normalized brightness information under different gray scales, and the gamma curve of the transparent display area approaches to the gamma curve of the normal display area by adjusting the voltage value of the first signal data of the transparent display area by using the compensation coefficient.
In the embodiment of the application, the DDIC outputs the compensated signal data, so as to dispatch a new gray scale and realize the brightness compensation process of the transparent display area.
Illustratively, as shown in fig. 5, for an exemplary schematic diagram of implementing luminance compensation on a transparent display area in a DDIC provided by an embodiment of the present application, a terminal inputs first signal data of the transparent display area and second signal data of a normal display area into the DDIC,
1. respectively carrying out service life calculation on first signal data of the transparent display area and second signal data of the normal display area by utilizing a pixel feedback accumulation algorithm built in the DDIC to obtain first service time of the transparent display area under the standard brightness and second service time of the normal display area under the standard brightness;

3. determining a difference value between the first brightness attenuation information and the second brightness attenuation information as a brightness difference between the transparent display area and the normal display area;
4. based on the brightness difference, searching a compensation value from a compensation data table in the DDIC;
5. adding the compensation value to the first signal data to obtain compensated first signal data;
6. and outputting the compensated first signal data and second signal data from the DDIC, controlling the transparent display area to display by using the compensated first signal data, and controlling the normal display area to display by using the second signal data.
It can be understood that, in the embodiment of the present application, the terminal controls the display of the display screen by using the compensated signal data, and since the compensated signal data is the screen display signal that has undergone the brightness compensation process with respect to the image area corresponding to the transparent display area, the image displayed on the display screen will have the effect of no brightness difference, that is, visually, the user can see that the brightness of each area of the image displayed in the transparent display area and the normal display area is the same.
It can be understood that, in the embodiment of the present application, the terminal may control the driving circuit to correspondingly supply power to different pixels in the display screen according to the compensated signal data, so as to display an image on the display screen. The compensated signal data is substantially identical to the on-screen display signal content represented by the signal data input to the DDIC, except that the display is performed in accordance with the compensated signal data, and the luminance effects displayed in the transmissive display region and the normal display region are identical.
It should be noted that, in the embodiment of the present application, in step S102, after the terminal determines the brightness difference between the transparent display area and the normal display area, the brightness difference may not exceed the preset difference threshold, and therefore, after the terminal determines the brightness difference between the transparent display area and the normal display area based on the first duration of use and the second duration of use, the method further includes: and under the condition that the brightness difference does not exceed the preset difference threshold value, stopping the brightness compensation process of the light-transmitting display area, and directly controlling the display screen to display by using the signal data of the display screen.
It can be understood that, in the embodiment of the present application, since the luminance decay rate of the display screen itself is relatively slow, the display correction of the light-transmitting display area does not need to be performed in real time, and the correction is performed when the luminance difference is selected to a certain extent.
