Problems solved by technology

However, because the colored light emitted by the three-color sub-pixels is produced through the color filter, the color filter filters the white light emitted by the light source on the back panel to generate colored light. Only a small part of the light that sees through, so the efficiency is not good
[0003] For this, as Figure 1b As shown in , an RGBW color liquid crystal display composed of four sub-pixels of red sub-pixel 11, blue sub-pixel 12, green sub-pixel 13 and brightness sub-pixel 14 has been developed, and this type of display is used in most It can have good image quality in any display state, but it can't show high-brightness solid color

Embodiment Construction

[0033] See figure 2 , is a functional block diagram of the display system developed in this case to improve the lack of conventional means, which mainly includes a display unit 2, which has a plurality of display pixels (not all shown in the figure), for example, a 1920*1080 A liquid crystal display panel displaying pixels. Any display pixel 20 in the display pixels has M sub-pixels displaying the first color component to the Mth color component and a mixed color sub-pixel. Taking the common configuration of M=3 as an example, the display pixel 20 has respectively A first sub-pixel 201 , a second sub-pixel 202 , a third sub-pixel 203 displaying three colors, and a fourth sub-pixel 204 which is different from the above three colors but is a mixed color. Common examples are red sub-pixels, green sub-pixels, blue sub-pixels and luminance sub-pixels for enhancing or compensating luminance, such as white sub-pixels or other high-luminance color mixing sub-pixels. For the conveni...

Abstract

The invention relates to a display system and a display unit control method. The display system comprises a plurality of display pixels, each display pixel comprises M sub-pixels which can form a color space and a color mixing sub-pixels in the color space, and the method comprises the steps of using the display system to carry out s first operation according to N color component values in a color component value set to thereby obtain a brightness component value representing brightness; using the display system to receive the color component value and the brightness component value to carry out a second operation to thereby generate a first set of color values and a second set of color values respectively, finally generating a control signal according to the first or second set of color values and outputting the control signal to the display unit to control the display pixels to display.

Description

【Technical field】 [0001] The invention relates to a display system and a display unit control method, in particular to a display system with a backlight source and a display unit control method. 【Background technique】 [0002] like Figure 1a As shown in FIG. 1 , each pixel (pixel) 1 in a conventional color liquid crystal display is composed of three subpixels: a red subpixel (subpixel) 11 , a blue subpixel 12 and a green subpixel 13 . In this traditional way, to display a white block, the three-color sub-pixels in each pixel in the block must be turned on to the brightest. On the contrary, if a black block is to be displayed, the three-color sub-pixels in each pixel in the block should be All must be closed. However, because the colored light emitted by the three-color sub-pixels is produced through the color filter, the color filter filters the white light emitted by the light source on the back panel to generate colored light. Only a small part of the light that sees th...
