Image display method

Abstract

The invention relates to a screen display method. The invention is characterized in that each pixel comprises a red sub-pixel, a green sub-pixel, a blue sub-pixel and a mixed color sub-pixel that is mixed by any two sub-pixels from red, green and blue sub-pixels. The color filter device chooses the materials with excellent color saturation as the sub-pixels to upgrade color range and keeps white balance status by adjusting the area of the sub-pixels and matching a specific arithmetic simultaneously.

Description

technical field [0001] The invention relates to a picture display method, in particular to a picture display method for calculating sub-pixel output values ​​of a color filter device. Background technique [0002] With the advancement of science and technology, in recent years, most electronic devices are light, thin and small as the main appeal. Among them, liquid crystal display is not only mature in technology but also has many participating manufacturers, so its market share has an absolute advantage. However, since the liquid crystal molecules in the liquid crystal display do not have luminous properties, a backlight and a color filter must be used to enable the display to display color images. [0003] Each pixel of a conventional color filter is composed of three sub-pixels of R, G, and B. Therefore, when light sources of different intensities pass through these sub-pixels and mix colors, the pixels can display different colors and brightness. However, the color filt...

In addition, since the pixel penetration area is proportional to the brightness, when the area of ​​G is smaller than B, the direction of color gamut expansion will deviate from the blue area instead of linear expansion.
