S101: acquiring the gray scale number of a target pixel and the maximum brightness of a display area pixel; the target pixel is any one of a plurality of pixels included in the arc angle area; the arc angle area is an area in the display area after pixels are removed along an arc line.
It should be noted that, each pixel in the display area is not required to be covered by a metal wiring, and each pixel in the display area is the same, so that the maximum brightness of the pixel in the display area can be obtained according to the screen parameters, and the maximum brightness of the pixel in the display area can also be obtained through equipment measurement. And can be 500nit, 800nit and 1000nit generally, the application is not limited in particular herein, and the application is determined according to practical situations.
The arc angle area is an area of the display area after the pixels are removed along the arc line, and comprises a grooved area, a punching area and a reverse arc angle area.
S102: and determining the target brightness of the target pixel according to the gray scale number of the target pixel and the maximum brightness of the display area pixel.
Specifically, the determining the target brightness of the target pixel according to the gray scale number of the target pixel and the maximum brightness of the display area pixel specifically includes: determining a target brightness of the target pixel according to the formula l= [ (X/255) ×γ ] ×l max; wherein L is the target brightness of the target pixel, X is the gray scale number of the target pixel, γ is a preset gamma value, and L max is the maximum brightness of the display region pixel.
It should be noted that, since the luminance recognizable by the human eye does not have a linear relationship with the actual luminance, the preset gamma value may be 2.2,1.8 or 1.0, and when the gamma value is 2.2, the human eye recognizes that the progressive process of each gray-scale luminance is equidistant. In order to achieve the best visual effect, the preset gamma value is set to be 2.2, but the application is not limited to the gamma value of 2.2, and the gamma value can be adjusted according to actual conditions and is within the protection scope of the application.
Specifically, as shown in fig. 4, the curve is a curve of gray scale and brightness, where X is the gray scale of a pixel, L is the brightness of the pixel, the curve includes three curves of gamma value 2.2,1.8 and 1.0, the opening area of the pixel in the arc angle area is finally assigned according to the curve, that is, the target brightness of the target pixel is determined according to the curve, and then the opening area of the target pixel is determined, so that the processed pixel looks more natural to the human eye without abrupt change.
S103: and acquiring the actual brightness of the target pixel.
It should be noted that, the arc angle area pixels of the screen body and the display area pixels keep the same design, and before the arc angle area pixels are not processed, the arc angle area pixels and the display area pixels have the same pixel size and the same pixel brightness.
Specifically, the actual brightness of the target pixel can be obtained through measurement by the device, and the actual brightness of the target pixel can also be obtained according to the device parameters because the pixels in the arc angle area of the screen body and the pixels in the display area keep the same design.
S104: and determining the opening area of the target pixel according to the target brightness and the actual brightness.
Specifically, determining the opening area of the target pixel according to the target brightness and the actual brightness specifically includes: judging whether the actual brightness is equal to the target brightness; and if the actual brightness is not equal to the target brightness, acquiring a target opening area corresponding to the target brightness, and taking the target opening area corresponding to the target brightness as the opening area of the target pixel.
Specifically, obtaining the target opening area corresponding to the target brightness includes: acquiring a pre-stored mapping table of pixel brightness and opening area; and inquiring the mapping table of pixel brightness and opening area by using the target brightness to obtain a target opening area corresponding to the target brightness.
It should be noted that, in this embodiment of the present application, the mapping table of pixel brightness and opening area includes an opening area corresponding to each pixel brightness, and the opening area corresponding to each pixel brightness may be obtained by continuously adjusting the opening area of the pixel for testing. After the target brightness of the pixel is determined, the opening area of the pixel can be obtained through looking up a table, so that the opening area of the pixel after the adjustment is the same as the opening area of the target brightness through adjusting the coverage area of the metal wiring on the pixel, the actual brightness of the pixel after the adjustment is adjusted to the target brightness, and saw teeth and color edges are reduced.
S105: determining the coverage area of the metal wire on the opening of the target pixel according to the opening area of the target pixel to obtain the target pixel covered with the metal wire; wherein the coverage area of the metal wire on the opening of the target pixel is inversely related to the opening area of the target pixel.
It should be noted that, the coverage area of the metal wire on the opening of the target pixel is inversely related to the opening area of the target pixel, that is, the more the metal wire coverage area is, the less the opening area of the target pixel is, and the coverage area of the metal wire is related to the opening area of the pixel.
Specifically, determining a coverage area of a metal wire on an opening of the target pixel according to the opening area of the target pixel to obtain the target pixel covered with the metal wire, which specifically includes: determining the coverage area of the metal wire on the opening of the target pixel according to the target opening area corresponding to the target brightness; covering the opening of the target pixel by using the metal wire according to the coverage area of the metal wire on the opening of the target pixel, so as to obtain the target pixel covered with the metal wire; the opening area of the target pixel covered with the metal wire is equal to the target opening area corresponding to the target brightness.
It should be noted that, when designing the minimum unit sensor of the TP, the Touch screen (Touch Panel, TP) pulls the metal trace onto the pixel opening at the sawtooth position of the arc corner area, and blocks part of the pixel openings to reduce the light output amount, thereby achieving the effect of eliminating sawtooth and color edge display.
