detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The method for adjusting the display screen provided by the embodiment of the present invention is applied to terminals, and the terminals include electronic devices such as smart phones, tablet computers, smart wearable devices, digital audio and video players, e-readers, handheld game consoles, and vehicle-mounted electronic devices. . In the embodiment of the present invention, the display screen configured on the terminal is an OLED display screen, and the OLED display screen is a display screen made of organic light-emitting materials, wherein the organic light-emitting materials can emit colored light when electrified.

It should be understood that the OLED display screen is formed by an array of light-emitting pixels, and each light-emitting pixel is formed by three organic light-emitting materials of red (R), green (G) and blue (B). Different colors can be obtained by mixing green and blue according to different grayscale ratios. It should also be understood that the greater the driving current flowing through the organic light emitting material, the higher the brightness of the organic light emitting material. However, as time goes by, the organic light-emitting material gradually decays and ages, and its impedance increases, so that under the same driving voltage, the driving current becomes smaller, resulting in a decrease in brightness, thereby causing display errors of the OLED display.

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

S101. Divide the display screen into a plurality of unit display areas.

Specifically, the terminal divides the display area of the display screen into multiple unit display areas. Optionally, the way the terminal divides the unit display area can be any of the following ways:

① Divide the display screen into multiple unit display areas in the form of a matrix array. Wherein, the number of rows and the number of columns of the matrix array may be preset, which is not specifically limited here. For example: please refer to Figure 5, as shown in the figure, the terminal can divide the display screen into 9 unit display areas in the form of a 3X3 matrix array.

②Dividing 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 icons, signal icons, battery icons, etc.), the virtual button bar is used to display virtual button icons (such as menu button icons, home button icons, return button icons, etc.), and the main display The area is the display area except the status bar and the virtual key bar. For example: please refer to Figure 6, as shown in the figure, the terminal can divide the display screen into three unit display areas, area 1 is the status bar, area 2 is the main display area, and area 3 is the virtual button bar. It should be pointed out that the attenuation and aging speed of organic light-emitting materials in different functional areas is different. The status bar and virtual button bar are generally displayed for a long time, and the organic light-emitting materials in their positions are consumed faster, while the main display Since the display content of the area changes over a long period of time, the consumption rate of the organic light-emitting material at the location is relatively slow, 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 embodiment of the present invention, and it should be understood that the embodiment of the present invention should not be limited to this example.

As an optional implementation manner, if the preset calibration picture is a calibration picture or a calibration animation, the terminal may execute step S102 after acquiring a display screen calibration instruction input by a user. For example: after the user clicks on the display screen calibration option in the system settings, the terminal executes step S102.

As another optional implementation manner, if the preset calibration screen is a startup animation, the terminal executes step S102 during each startup process.

Optionally, the terminal only increases the drive current of any unit display area when it determines that the difference between the reference current value set corresponding to any unit display area and the drive current value of the unit display area is greater than or equal to a preset threshold. The reason is that when the driving current value of the unit display area is not much different from the corresponding reference current value, the brightness is also not much different, and the user cannot distinguish the brightness difference with the naked eye, and there is no need to increase the driving current at this time.
