Embodiment Construction

[0018] The specific implementation of the method for customizing the light source color of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 A flow chart of a method for customizing light source colors in an embodiment is shown, including the following steps:

[0020] Step S10: collecting the chromaticity and brightness of each color of each display unit of the multi-screen display device.

[0021] In one embodiment, the color of each display unit of the multi-screen display device is measured and collected by using a color measuring instrument (such as a wireless spectrometer), and the collected data includes the color values ​​of R, G, B, W, Y, C, and M colors. The color gamut range of the multi-screen display device can be determined through the above parameters.

[0022] Step S20: Calculate the customized luminance values ​​corresponding to the target chromaticity and luminance for displaying the R, G...

Abstract

The invention discloses a light source color custom method and a light source color custom system. The light source color custom method includes the following steps: the chromaticity and the brightness of each color of each display unit of a multi-screen display unit are acquired; custom brightness values corresponding to target chromaticity and brightness displayed by light sources of R, G and B of each display unit are calculated according to the chromaticity and the brightness; custom current values corresponding to the light sources of R, G and B of each display unit are calculated according to the custom brightness values and a relation model between the brightness of the light sources of R, G and B and current; and colors of the light sources of R, G and B of each display unit are customized according to the custom current values. Due to the technologies, the custom of the colors of the light sources of the multi-screen display unit is achieved, color uniformity of each display unit is improved, and the display effect of the multi-screen display unit is promoted.

Description

technical field [0001] The invention relates to color correction technology, in particular to a method and system for customizing the color of a light source. Background technique [0002] A multi-screen display device (such as a splicing wall) is a large-screen display system composed of multiple display units and image controllers. It is generally used for super-large screen display of one screen and multi-window display of multiple screens. Due to the differences in the color parameters (luminance, chromaticity) of the R, G, and B light sources of different display units, and the different duty cycles of the R, G, and B light sources of different display units, different display units on the multi-screen display device There are large differences in the color attributes of R (red), G (green), B (blue), M (magenta), C (cyan), Y (yellow), and W (white), which reduces the display effect. Contents of the invention [0003] Based on this, it is necessary to provide a method...
