Embodiment Construction
[0011] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0012] This specific embodiment adopts the following technical solution: by controlling the different brightness ratios of the red, green and blue LED lamp beads on the LED display screen, thousands of changing colors can be obtained. In the application of LED display, according to the principle of color mixing, the brightness (LvW) of the white light obtained by mixing red, green and blue colors is the sum of the brightness of red, green and blue colors (LvR, LvG, LvB), and the CIE1931 of white light The color coordinates are determined by the tristimulus values (X, Y, Z) of red, green, and blue, and the relationship is as follows:
[0013] …………(1)
[0014] The relationship between color coordinates and tristimulus values is as follows: ...
