Embodiment Construction

[0068] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0069] First, explain the meaning of some terms in this article.

[0070] The term "pixel", also known as pixel, is the basic unit of image display, translated from English "pixel", pix is ​​a common abbreviation of the English word picture, and the English word "element" is added to get pixel, so "pixel" means Means "picture element". Each pixel can have its own color value, so there is a corresponding concept of "sub-pixel". Four sub-pixels of magenta, yellow and black (CMYK color gamut, common in the printing industry and printers), or four sub-pixels of red, green, blue and white (RGBW color gamut), or more primary colors.

[0071] The term "primary color" (also called "primary color") refers to each color in a repeating group of sub-pixels, ...

Abstract

A display panel, a display apparatus and a sub-pixel rendering method. The display panel is constituted by repeating pixel groups. Each pixel group is composed of a pre-determined number of pixels arranged in a row, and each pixel is constituted by arraying sub-pixels of at least two different primary colors in different orders, wherein adjacent sub-pixels between adjacent pixels in each pixel group or adjacent sub-pixels between adjacent pixel pairs in each pixel group have an identical color. The adjacent sub-pixels having the identical color increase the saturation of a displayed color, so that a colored display screen has a higher color saturation, the displayed color is brighter, and levels are richer. One or more pairs among pairs constituted by the adjacent sub-pixels, having the identical color, of the adjacent pixels in each pixel group and pairs constituted by the adjacent sub-pixels, having the identical color, of the adjacent pixels between the pixel groups can be combined into a super sub-pixel, there is no black gap in the super sub-pixel, and the brightness of the super sub-pixel is greater than that of any one of the combined original sub-pixels having the identical color. The configuration of the super sub-pixel improves the utilization rate of a light source, reduces power consumption and also takes high pixel density into account.

Description

technical field [0001] The present invention relates to a display panel and a display device, which can be used as a color display panel and a display device for various devices such as mobile phones, tablet computers, notebook computers, monitors, and televisions, and also relates to a sub-pixel rendering method of the display device. Background technique [0002] Various color display screens currently widely used, such as cathode ray tube (Cathode Ray Tube, CRT) display screen, light-emitting diode (light-emitting diode, LED) display screen, organic light-emitting diode (Organic LightEmitting Diode, OLED) display screen, A liquid crystal display (LCD), etc., is formed by arranging pixels. A color display screen contains multiple pixels, such as 640x480, 1024x768, 1920x1080 pixels, etc. Each pixel includes two or three or more sub-pixels of different colors. The more common one is that each pixel has three sub-pixels, that is, a red sub-pixel, a green sub-pixel, and a bl...
