Pixel structure, display panel and display device

Abstract

The invention provides a pixel structure, a display panel and a display device and belongs to the technical field of display. The pixel structure comprises a plurality of pixel units, wherein each pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel which are arrayed in sequence along a first direction; the first sub-pixels, the second sub-pixels and the third sub-pixels are rectangular; the length directions of the first sub-pixels, the second sub-pixels and the third sub-pixels are a second direction vertical to the first direction; each pixel unit further comprises a rectangular white sub-pixel; pixel groups formed by the first sub-pixels, the second sub-pixels and the third sub-pixels and the white sub-pixels are arrayed in the second direction; and the length directions of the white sub-pixels are the first direction. With the adoption of the technical scheme provided by the invention, the transmittance of the display panel can be improved, and the resolution ratio of RGB (Red, Green and Blue) sub-pixels in the arraying direction is not influenced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure, a display panel and a display device. Background technique [0002] Among flat panel display technologies, liquid crystal displays are widely used in real life due to their low power consumption, relatively low manufacturing cost and low radiation. The existing liquid crystal display is mainly composed of a display panel, a driving circuit and a backlight source, wherein the display panel is mainly composed of a color filter substrate, a liquid crystal layer, and a TFT (Thin Film Field Effect Transistor) substrate. The traditional color filter substrate is mainly composed of red, green and blue (R / G / B) filter layers. Each pixel unit of the display panel contains RGB sub-pixels. Deflection, changing the transmittance of light passing through each sub-pixel, affecting the brightness of light in each sub-pixel, and then forming different patterns and col...

Problems solved by technology

[0003] However, after the light emitted by the backlight passes through the color filter substrate, nearly 2 / 3 of the visible light is absorbed by the red, green and blue filter layer, and only about 1 / 3 of the visible light passes through the color filter substrate, resulting in a low utilization rate of visible light. , in order to make the display device reach the required brightness, it is necessary to increase the brightness of the backlight, which increases the power consumption of the display device

In order to reduce the power consumption of the display device and increase the transmittance of the display panel, the prior art introduces white sub-pixels into the pixel unit, which greatly improves the transmittance of the display panel, but in the existing pixel unit, Generally, red sub-pixels, green sub-pixels, blue sub-pixels and white sub-pixels are arranged sequentially in the same direction, which affects the resolution of RGB pixels in this arrangement direction.
