Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0017] figure 1 The flowchart of the method for increasing the display color gamut of the LED display screen provided by the embodiment of the present invention is shown.

[0018] The method includes the following steps:

[0019] In step S101, determine the range of three color wavelengths;

[0020] In step S102, an orange-yellow LED with a wavelength of about 580nm is added to each pixel;

[0021] In step S103, DVI recalculates to generate the data of four colors of red, green, yellow and blue;

[0022] In step S104, a group of data signals of red, green, yellow and blue is assigned, and the four-...

Abstract

The invention belongs to the technical field of display screen manufacturing and provides a method for increasing the display color gamut of an LED display screen. On the basis of determining the range of tricolor wavelength, an orange-yellow LED of which the wavelength is about 580nm is added at each pixel; then recalculation is carried out through a DVI to generate data of red, green, yellow and blue; and finally, a group of data signals is given to each of the four colors: red, green, yellow and blue, and the data signals of the four colors are scattered to red, green, yellow and blue lamps for display. According to the method, the orange-yellow LED of which the wavelength is about 580nm is added so that the color gamut which can be displayed by the LED display screen is a quadrangle. Compared with an LED display screen adopting the trichromatic theory, the display color gamut is increased by 10%, the display effect of the LED display screen is greatly improved, the production and use costs are low, and the method has strong popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of display screen manufacturing, and in particular relates to a method for increasing the display color gamut of an LED display screen. Background technique [0002] Existing LED TV sets adopt the principle of three primary colors, which is the basis of color TV technology. According to the visual characteristics of the human eye, the image is reproduced in the TV equipment. It is not required to completely reproduce the spectral components of the reflected or transmitted light of the original scene. It only needs to imitate the three cone cells of the human eye. Choose three primary colors (three primary colors Must be independent of each other, any one primary color cannot be obtained by mixing the other two primary colors). By combining them in different proportions, most colors in nature can be obtained. The three kinds of monochromatic light with these characteristics are called primary color light. Th...
