Problems solved by technology

Since the structure of the pixel units in the display area of ​​the display screen is mostly arranged in a rectangular array structure, for the non-special-shaped display screen with a rectangular shape as a whole, the sub-pixels in the pixel unit are distributed regularly and the edges are even, while for the special-shaped display screen, The arc design of the special-shaped cutting area will cause the sub-pixels to be distributed in a stepped manner at the arc cutting line, resulting in obvious jaggedness near the arc cutting line

Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0027] In one embodiment, such as figure 1 As shown, a display control method for edge display is provided, which can be applied to a control device, and the method includes the following steps:

[0028] S110: Determine an arc cutting line, the arc cutting line cuts at least part of the edge sub-pixels of the display screen, and the light-emitting area of ​​each edge sub-pixel passed by the arc cutting line is divided into a first area and a second area.

[0029] Among them, the arc cutting line is the contour line of the display screen, which is located at the arc edge o...

Abstract

The invention relates to a display screen edge display control method and device, and a display device. The display screen edge display control method comprises the steps that an arc cutting line is determined and cuts at least part of edge sub pixels of a display screen, and a light-emitting area of each edge sub pixel penetrated by the arc cutting line is divided into a first area body and a second area body; under a two-dimensional coordinate system of a plane where the sub pixels of the display screen are located, all vertex coordinates of the edge sub pixels, the radius of a circle wherethe arc cutting line is located, and the circle center coordinate of the circle where the arc cutting line is located are obtained; according to all the vertex coordinates, the circle center coordinate and the radius of the circle where the arc cutting line is located, area proportion coefficients of the edge sub pixels are calculated; according to the area proportion coefficients and the preset brightness value of the edge sub pixels, the optimized brightness value smaller than the preset brightness value is obtained; and the edge sub pixels conduct displaying through the optimized brightnessvalue. By adopting the display screen edge display control method, the display effect of the display screen can be optimized.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for controlling edge display of a display screen, a control device and a display device. Background technique [0002] With the development of display technology, "full screen" devices are gradually emerging. A full-screen device refers to a device with a screen-to-body ratio close to 100%. In order to achieve a full-screen display, it is inevitable to perform special-shaped cutting in the display area of ​​the screen. Generally, the cut edges are rounded and chamfered. For example, chamfer the four top corners of the display screen, and the four top corners of the display screen are rounded. Grooves with straight lines connecting arcs. [0003] The display screen that is cut in a special shape is a special-shaped display screen, and the edge line of the arc-shaped chamfer obtained by cutting is the arc cutting line of the special-shaped display screen. ...
