Embodiment Construction

[0024] Hereinafter, the present invention will be described with reference to the drawings and examples.

[0025] figure 1 It is a flow chart of an embodiment of the RGBW display method of the present invention. Such as figure 1 As shown, the RGBW display method of the present invention includes:

[0026] Step S101, partitioning the color gamut of the RGBW display device;

[0027] In this step, the color gamut of the RGBW display device is divided into multiple color gamut areas, and the W value of each color gamut area is set.

[0028] Here, the plurality of color gamut areas include a high chroma area and a low chroma area, the W value of the high chroma area is set as the minimum or lower limit value of the RGB values ​​of the areas, and the low chroma The W value of the degree area is set to the maximum value or the upper limit value of the RGB values ​​of the area. Among them, the high chroma area refers to the area where a single pixel value is very high and the oth...

Abstract

The invention provides a red, green, blue and white (RGBW) display method. The RGBW display method comprises the steps that a color gamut of an RGBW display device is divided into a plurality of color gamut regions, and in addition, the W value of each color gamut region is set; images are divided into a rough image region and a detain image region according to the RGB value of images to be displayed; the W value of pixels in the rough image region is set as the maximum value or the upper limit value of the RGB value of the pixels, and the W value of pixels in the detail image region is set according to the W value of each gamut region; and the images are displayed according to the RGB value and the W value. In addition, the corresponding RGBW display device is provided. The RGBW display technology can give consideration to both of the color gamut and the transmittance of the RGBW display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to an RGBW display method and an RGBW display device. Background technique [0002] The principle of RGBW LCD screen technology is to add a white (W) sub-pixel to the traditional RGB pixel composed of red (R), green (G) and blue (B), and then apply the corresponding sub-pixel Pixel imaging technology better aligns those sub-pixels in the way humans see images. This ensures that display power and brightness sources are not lost when generating images that cannot be seen by the human eye. PenTile sub-pixel imaging technology addresses each sub-pixel individually, and adds a white (clear) sub-pixel to the arrangement pattern to form an RGBW pixel design, which is better than the traditional RGB pixel design display Brighter and higher resolution. Because more backlight can emit light through the larger and semi-transparent W sub-pixels, rather than being blocked by th...
