Display device, preparation method thereof and method for converting color gamut standard of display device

Abstract

The invention provides a display device, a preparation method thereof and a method for converting a color gamut standard of the display device. The display device comprises a display panel, wherein the display panel comprises a display substrate and a plurality of pixel units, the pixel units are arranged on the first surface of the display substrate, each pixel unit comprises a plurality of sub-pixels, the sub-pixels comprise variable sub-pixels, and the variable sub-pixels are used for emitting light in at least one preset color according to the preset color gamut standard. Therefore, the color cast phenomenon of the display device can be improved by the light, emitted by the variable sub-pixels, in the preset color, then the displaying smoothness degree, color purity, the color gamut and various optical characteristics of images of the display device are improved, the display device can meet the requirements of different color gamut standards, and the situation that the displaying smoothness degree, the color purity, the color gamut and various optical characteristics of the images are reduced due to different color gamut standards is avoided.

Description

technical field [0001] The invention relates to the display field, in particular, to a display device, a manufacturing method thereof and a method for converting the color gamut standard of the display device. Background technique [0002] RGBW pixel arrangement liquid crystal display technology is widely used in 4K (UHD) and above high-resolution and large-size display devices. On the basis of small colorimetric characteristics, the transmittance of the panel is greatly improved. However, compared with products with traditional RGB pixel arrangement, due to the addition of W pixels, various optical characteristics such as the fineness of the picture performance, color purity, and color gamut have been reduced, such as red is not red enough, blue is not blue enough, and green is not enough Green and so on. [0003] Therefore, the research on the liquid crystal display device still needs to be deepened. Contents of the invention [0004] The present invention aims to sol...

Problems solved by technology

However, compared with products with traditional RGB pixel arrangement, due to the addition of W pixels, various optical characteristics such as the fineness of the picture performance, color purity, and color gamut have been reduced, such as red is not red enough, blue is not blue enough, and green is not enough Green etc.

[0003] Therefore, research on liquid crystal display devices still needs to be deepened.
