Problems solved by technology

Take the white screen as an example, such as figure 2 As shown, visually, it changes directly from high-brightness white to black. The contrast between pure white and pure black is high, and the jaggedness will be more obvious, resulting in poor display effect and affecting the look and feel.

Abstract

The invention provides a special-shaped display device, which relates to the field of liquid crystal display and comprises a main display area and an auxiliary display area positioned at the edge of the main display area, the main display area and the auxiliary display area are respectively provided with a plurality of repeatedly arranged pixel units, and each pixel unit is provided with m (m is equal to 3 or 4) sub-pixels; the display driving circuit is arranged in the auxiliary display area and is correspondingly matched with each sub-pixel, wherein the nth (n > = 1, and n is an integer) sub-pixel of the ith pixel unit (i is an integer greater than or equal to 1 and less than or equal to m) of the sub-display area corresponds to the nth display driving circuit, and the nth display driving circuit shares a data line of the ith sub-pixel of the pixel unit on the outermost side of the main display area; and after an adjustable dimming duty ratio signal is input, the display driving circuit controls the brightness of the sub-pixels, so that the brightness of the pixel units in the auxiliary display area is gradually reduced compared with the brightness of the pixel units on the outermost side of the main display area.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a special-shaped display device. Background technique [0002] Traditional display screens are generally rectangular. With the development of technology, special-shaped display screens have appeared on the market, which we call special-shaped screens. [0003] In order to avoid abnormal display color of the picture presented at the irregular edge of the main display area of ​​the special-shaped screen, there are usually multiple sets of complete RGB three sub-pixels at the irregular edge, so that the spatial pixel units between each row The arrangement is not smooth but jagged. When the screen is displayed, it will feel that the edges are jagged, such as figure 1 shown. [0004] When the brightness of the edge of the main display area is brighter, there will be a more obvious difference in brightness from the black outer frame outside the main display area. T...
