Embodiment Construction

[0017] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, Features and their functions are described in detail below.

[0018] An embodiment of the present invention provides a method for improving the display effect of the edge of a circular display screen, the method comprising:

[0019] determining the edge area and central area of ​​the circular display;

[0020] dividing the edge area of ​​the circular display screen into n brightness level display areas along the direction in which the geometric center of the circular display screen points to the edge area;

[0021] adjusting the pixels in the edge area to the corresponding target brightness according to the display brightness of the pixels in the central area and the brightness levels of the n brightness level display areas;

[0022] Wherein, along the direction in which the geometric center of t...

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...
