本申请涉及显示领域，特别是涉及一种显示面板及曲面显示装置。The present application relates to the display field, in particular to a display panel and a curved display device.
背景技术Background technique
液晶显示器(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，在平板显示领域中占主导地位。A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, and no radiation, etc., has been widely used, and occupies a dominant position in the field of flat panel display.
近年来，随着液晶显示技术的发展，各大厂商陆续的推出了曲面(Curved)液晶显示器，整体而言，曲面液晶显示装置从边缘到边缘都能提供最佳的观看效果，而普通的液晶显示装置在屏幕边缘方面的呈现能力一直相对不太理想，存在色偏等问题。而曲面液晶显示装置的弧形设计，可提供宽阔的全景影像效果，不论是在屏幕中央还是边缘四周，都能够带来良好的视觉享受，并且在近距离观看时还减少了离轴观看的失真度。此外，曲面液晶显示装置会让用户的观赏距离拉长，达到更好的观赏体验。因此，相比于普通的液晶显示装置，曲面液晶显示装置有着很大的优势。In recent years, with the development of liquid crystal display technology, major manufacturers have introduced curved liquid crystal displays one after another. Generally speaking, curved liquid crystal display devices can provide the best viewing effect from edge to edge, while ordinary liquid crystal displays The rendering ability of the display device at the edge of the screen has been relatively unsatisfactory, and there are problems such as color shift. The curved design of the curved liquid crystal display device can provide a wide panoramic image effect, whether it is in the center of the screen or around the edge, it can bring good visual enjoyment, and it also reduces the distortion of off-axis viewing when viewed at a close distance Spend. In addition, the curved liquid crystal display device can lengthen the viewing distance of the user to achieve a better viewing experience. Therefore, compared with common liquid crystal display devices, curved liquid crystal display devices have great advantages.
对于曲面液晶显示装置而言，其所采用的像素电极通常需要在普通的液晶显示装置的基础上做变形设计，以有利于液晶显示装置的弯曲，把普通的“米”字型像素电极沿着其竖直中心线一分为二，再把右侧的部分像素电极连接到左侧的像素电极的下方，这样可以保证LCD在弯曲时各个区域内的像素偏移程度相同，保证显示效果，由于曲面显示装置的曲面设计，两基板的相对移动量从中间往两边是逐渐增大，液晶面板的中心区无相对移动量，液晶面板的中心区上的子像素内的像素电极不偏移或，而液晶面板左右两侧区域上的子像素内的像素电极发生偏移，形成暗纹区，这样就会造成中心区和暗纹区有明显的亮度差异，使得面板出现暗纹的现象。For curved liquid crystal display devices, the pixel electrodes used usually need to be deformed on the basis of ordinary liquid crystal display devices to facilitate the bending of liquid crystal display devices. Its vertical center line is divided into two, and then part of the pixel electrodes on the right are connected to the bottom of the left pixel electrodes, which can ensure that the pixel offset in each area of the LCD is the same when it is bent, and the display effect is guaranteed. In the curved surface design of the curved surface display device, the relative movement of the two substrates gradually increases from the middle to both sides, there is no relative movement in the central area of the liquid crystal panel, and the pixel electrodes in the sub-pixels on the central area of the liquid crystal panel are not offset or, However, the pixel electrodes in the sub-pixels on the left and right sides of the liquid crystal panel are shifted to form a dark stripe area, which will cause a significant difference in brightness between the central area and the dark stripe area, resulting in dark stripes on the panel.
