Abstract

The invention provides a WRGB color saturation enhancing method. The method comprises the following steps of, firstly, inputting original RGB (red, green and blue) signals; secondly, converting the original RGB signals into an HSV (hue, saturation and value) color space; thirdly, transforming S and V to obtain a new HS'V' color space and to enhance the color saturation; fourthly, converting the HS'V' color space obtained in the third step to obtain R'G'B' signals; fifthly, converting the R'G'B' signals obtained in the fourth step to obtain W'R'G'B' signals; sixthly, outputting the W'R'G'B' signals. The WRGB color saturation enhancing method can enhance the color saturation of a liquid crystal display panel, achieve brighter display effects and higher picture quality and solve the problems of gray scale transition unsmoothness, watermarks in certain gray scales and the like in existing WRGB technologies.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for improving WRGB color saturation. Background technique [0002] Flat panel display devices such as Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) have gradually replaced CRT displays and become mainstream products in today's market. The display panel is an important part of flat panel display devices such as LCD and OLED. For LCD, the structure of its liquid crystal display panel is generally composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a configuration on the two substrates Its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on the two glass substrates, and refract the light provided by the backlight module to generate images.
