Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The chromatic aberration detection method provided by the embodiment of the present invention is applied to a terminal, and the terminal includes electronic equipment such as a smart phone, a tablet computer, a smart wearable device, a digital audio and video player, an electronic reader, a handheld game console, and an in-vehicle electronic device. In the embodiment of the present invention, the display screen configured by the terminal is an OLED display screen, and the OLED display screen is a display screen composed of organic light-emitting materials, wherein the organic light-emitting materials can emit colored light when powered on.

FIG. 1 is a schematic flowchart of a method for detecting a display screen in an embodiment of the present invention. As shown in the figure, the flow of the detection method of the display screen in this embodiment may include:

S101, dividing the display screen into a plurality of unit display areas.

Specifically, the terminal divides the display area of the display screen into a plurality of unit display areas. Optionally, the manner in which the terminal divides the unit display area may be any one of the following manners:

① Divide the display screen into multiple unit display areas in the form of a matrix array. The number of rows and columns of the matrix array may be preset, which is not specifically limited here. For example, please refer to Figure 6. As shown in the figure, the terminal can divide the display screen into 36 unit display areas in the form of a 6X6 matrix array.

② Divide the display screen into a plurality of unit display areas according to functional areas, wherein the functional areas include a status bar, a main display area and a virtual key bar. Among them, the status bar is used to display status icons (such as operator icon, signal icon, battery icon, etc.), the virtual button bar is used to display virtual button icons (such as menu button icon, home button icon, return button icon, etc.), the main display The area is the display area other than the status bar and virtual key bar. For example, please refer to Figure 7. As shown in the figure, the terminal can divide the display screen into 3 unit display areas, area 1 is the status bar, area 2 is the main display area, and area 3 is the virtual key bar. It should be pointed out that the decay and aging speed of organic light-emitting materials in different functional areas is different. The background color of the status bar and virtual key bar is generally fixed to black for a long time, that is, it is not displayed. The organic light-emitting material in its location consumes faster than However, since the main display area is displayed for a long time, the organic light-emitting material at its location consumes faster, so the advantage of this division method is that it is easier to detect the aging area.

Of course, the above two division manners are only examples provided by the embodiments of the present invention, and it should be understood that the embodiments of the present invention should not be limited to the examples.

S102, recording the lighting time of each of the unit display areas within a preset time period.

As an optional implementation manner, a timer is set for each unit display area to record the lighting time of the respective unit display area respectively.

Wherein, the preset time period may be preset by the equipment manufacturer, or may be preset by the user, which is not limited here. Preferably, the preset time period is the time from the first lighting time to the current time . Specifically, the terminal records the lighting time accumulated from the moment when each unit display area is first turned on to the current moment. For example, the display screen of the terminal is lit for the first time after leaving the factory, and the user has purchased and used it until now. During this period, the terminal records the accumulated lighting time of each unit display area in the display screen.

S103 , by comparing the lighting time of each of the unit display areas with a preset time threshold, detect a unit display area with a color difference in the display screen.

The preset time threshold is preset by the equipment manufacturer, and the equipment manufacturer continuously lights up the same type of display screen, so that the organic light-emitting material of the display screen continues to be consumed. When there is a color difference that can be recognized by the human eye on the display screen, this time is used as the preset time threshold.

Specifically, when the terminal determines that the lighting time of any unit display area is greater than the preset time threshold, it determines that it is a unit display area with a color difference in the display screen. For example: refer to Figure 6, assuming that the preset time threshold is 4800 hours, and the accumulated lighting time of the 22nd unit display area in the display screen is 4852 hours, then the terminal determines that the 22nd unit display area is the unit display with color difference area. Another example: referring to Figure 7, assuming that the preset time threshold is 5200 hours, and the accumulated lighting time of the second unit display area in the display screen is 5268 hours, then the terminal determines that the second unit display area is a unit with color difference Display area.

Further, after detecting the unit display area with color difference in the display screen, the terminal performs brightness compensation on the unit display area with color difference.

Specifically, the manner in which the terminal performs luminance compensation on the unit display area with chromatic aberration can be implemented by the following steps:

Step 1: Calculate the time difference between the lighting time of the unit display area with color difference and a preset time threshold.

For example: refer to Figure 6, assuming that the 22nd unit display area in the display screen is an area with chromatic aberration, the preset time threshold is 4800 hours, and the accumulated lighting time of the 22nd unit display area is 4852 hours, then the terminal The calculated time difference is 52 (=4852-4800) hours.

Step 2: Determine the brightness compensation value corresponding to the time difference value, wherein a corresponding relationship is pre-established between the time difference value and the brightness compensation value.

For example: Assuming that the brightness corresponding to the maximum brightness level of the display screen is X, the following correspondence can be established: the time difference is 0 to 100 hours, and the corresponding brightness compensation value is X/100; the time difference is 100 to 200 hours , the corresponding brightness compensation value is X/100*2; the time difference value is 200-250 hours, and the corresponding brightness compensation value is X/100*3, and so on.

Step 3, according to the brightness compensation value, increase the brightness of the unit display area with chromatic aberration.

For example: refer to Figure 6, assuming that the brightness corresponding to the maximum brightness level of the display screen is X, the 22nd unit display area in the display screen is an area with color difference, the time difference value is 52 hours, and the corresponding brightness compensation value is X/100, then the terminal increases the brightness of the 22nd unit display area by X/100.

It should be pointed out that after increasing the brightness of the unit display area with chromatic aberration, the brightness of the unit display area should be restored to normal brightness, or the difference between the restored brightness and the normal brightness is indistinguishable with the naked eye.

Specifically, the manner in which the terminal increases the brightness of the unit display area with color difference may be realized by increasing the driving current or driving voltage of the area.

In the embodiment of the present invention, the display screen is first divided into a plurality of unit display areas, and then the lighting time of each unit display area within a preset time period is recorded, and then the lighting time of each unit display area and the preset time are recorded. The threshold value is compared to determine the unit display area with chromatic aberration, so as to detect the area with chromatic aberration in the display screen.

For example, please refer to Figure 6. As shown in the figure, the terminal can divide the display screen into 36 unit display areas in the form of a 6X6 matrix array.

② Divide the display screen into a plurality of unit display areas according to functional areas, wherein the functional areas include a status bar, a main display area and a virtual key bar. Among them, the status bar is used to display status icons (such as operator icon, signal icon, battery icon, etc.), the virtual button bar is used to display virtual button icons (such as menu button icon, home button icon, return button icon, etc.), the main display The area is the display area other than the status bar and virtual key bar. For example, please refer to Figure 7. As shown in the figure, the terminal can divide the display screen into 3 unit display areas, area 1 is the status bar, area 2 is the main display area, and area 3 is the virtual key bar. It should be pointed out that the decay and aging speed of organic light-emitting materials in different functional areas is different. The background color of the status bar and virtual key bar is generally fixed to black for a long time, that is, it is not displayed. The organic light-emitting material in its location consumes faster than However, since the main display area is displayed for a long time, the organic light-emitting material at its location consumes faster, so the advantage of this division method is that it is easier to detect the aging area.

For example: refer to Figure 6, assuming that the preset time threshold is 4800 hours, and the accumulated lighting time of the 22nd unit display area in the display screen is 4852 hours, then the terminal determines that the 22nd unit display area is the unit display with color difference area. Another example: referring to Figure 7, assuming that the preset time threshold is 5200 hours, and the accumulated lighting time of the second unit display area in the display screen is 5268 hours, then the terminal determines that the second unit display area is a unit with color difference Display area.

S204: Calculate the time difference between the lighting time of the unit display area with color difference and the preset time threshold.

For example: refer to Figure 6, assuming that the 22nd unit display area in the display screen is an area with chromatic aberration, the preset time threshold is 4800 hours, and the accumulated lighting time of the 22nd unit display area is 4852 hours, then the terminal The calculated time difference is 52 (=4852-4800) hours.

S205: Determine a brightness compensation value corresponding to the time difference value, wherein a corresponding relationship is pre-established between the time difference value and the brightness compensation value.

For example: Assuming that the brightness corresponding to the maximum brightness level of the display screen is X, the following correspondence can be established: the time difference is 0 to 100 hours, and the corresponding brightness compensation value is X/100; the time difference is 100 to 200 hours , the corresponding brightness compensation value is X/100*2; the time difference value is 200-250 hours, and the corresponding brightness compensation value is X/100*3, and so on.

S206, according to the brightness compensation value, increase the brightness of the unit display area with color difference.

For example: refer to Figure 6, assuming that the brightness corresponding to the maximum brightness level of the display screen is X, the 22nd unit display area in the display screen is an area with color difference, the time difference value is 52 hours, and the corresponding brightness compensation value is X/100, then the terminal increases the brightness of the 22nd unit display area by X/100.

It should be pointed out that after increasing the brightness of the unit display area with chromatic aberration, the brightness of the unit display area should be restored to normal brightness, or the difference between the restored brightness and the normal brightness is indistinguishable with the naked eye.
