Method for improving edge display effect of circular display screen

Abstract

The invention discloses a method for improving the edge display effect of a circular display screen. The method includes: determining the edge area and the central area of the circular display screen; dividing the edge area of the circular display screen into display areas of n brightness levels along a direction pointing from the geometrical center to the edge area; adjusting pixels in the edge area to corresponding target brightness according to the display brightness of pixels in the central area and the brightness levels of the display areas. By the method, the brightness of the pixels in the edge area is allowed to be lower than that of the central area, the brightness of the pixels in the display areas in the edge area sequentially decreases along the direction pointing from the central area to the edge area, and the problems of edge aliasing, color edges and bright edges of the circular display screen are improved.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to a method for improving the display effect of the edge of a circular display screen. Background technique [0002] With the wide application of display screens in various electronic devices, in order to meet the needs of different application scenarios, the shape of display screens is no longer limited to rectangles, and special-shaped display screens, especially circular display screens, have gradually become a research hotspot. [0003] In the prior art, a circular display screen includes a plurality of pixels arranged in rows. In order to adapt to the curved edge, pixels in adjacent rows have a step transition at the edge of the circular display screen. Since most of the pixels are rectangular, such a step transition is prone to edges. Aliasing. In addition, due to the relatively fixed arrangement of red pixels, green pixels, and blue pixels, the phenomenon of co...

[0003] In the prior art, a circular display screen includes a plurality of pixels arranged in rows. In order to adapt to the curved edge, pixels in adjacent rows have a step transition at the edge of the circular display screen. Since most of the pixels are rectangular, such a step transition is prone to edges. sawtooth phenomenon

In addition, due to the relatively fixed arrangement of red pixels, green pixels, and blue pixels, the color fringing at the edge of the circular display is more serious

On the other hand, the Mach band effect will also cause the brightness of the edge of the circular display screen to be larger when the human eye watches it, that is, the bright edge problem of the circular display screen will appear.
