Problems solved by technology

However, the whiteness of the RGB mixed color of the traditional RGBW display panel is different from the whiteness of the W sub-pixel, resulting in the need for more complex color adjustment calculations to achieve the RGBW white balance, thereby improving the white light color cast problem

Abstract

The invention provides a display device including a display panel, an input image signal unit and a sub-pixel imaging unit. The display panel includes a plurality of repetitive units, each including at least eight sub-pixels. The sub-pixels include two first color sub-pixels, two second color sub-pixels, two third color sub-pixels, at least one first white sub-pixels and at least one second white sub-pixels. The chromaticity of the first and the second white sub-pixels are different and the first and the second white sub-pixels are in different lines. The input image signal unit is used for receiving image signals. The sub-pixel imaging unit is used for sub-pixel imaging treatment for image signals, such that sub-pixels on the display panel can produce presentation values. The display device provided by the utility model can have good pixel opening rate and image vision resolution.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device capable of improving white light color shift and having good pixel aperture ratio and image visual resolution. Background technique [0002] With the advancement of science and technology, people have higher and higher requirements for display devices, such as thin and light display devices, high image quality, and low power consumption. Especially, for portable display devices, low power consumption and high brightness are the focus of attention. Therefore, in recent years, RGBW (red, green, blue and white) display panels capable of increasing the transmittance of the backlight and reducing energy consumption of the backlight have been developed. The RGBW display panel has sub-pixels of four colors: red, green, blue, and white, and the brightness of the display panel is improved through the high transmittance of white pixels. However, the whiteness of the RGB mixed ...
