Abstract

The present invention provides a display device and a color adjustment method. The display device comprises a storage unit for storing an original coordinate and a color parameter of a reference point in a color space which has been subjected to color correction in advance; a display unit for displaying an adjusting interface which is used for shifting the reference point so as to generate a shifting coordinate of the reference point; and a processing unit coupled to the storage unit and the display unit. The processing unit obtains a color conversion matrix according to the original coordinate of the reference point, the shifting coordinate of the reference point and the color parameter, and the processing unit adjusts the output percentage of the RGB according to the color conversion matrix. According to the display device and the color adjustment method of the invention, the display device can automatically calculate the color conversion matrix through the shifting reference point of the adjusting interface, adjust the output percentage of the RGB through the color conversion matrix, and then update the current color into the color adjusted by a user in real time.

Description

technical field [0001] The invention relates to the display field, in particular to a display device and a color adjustment method. Background technique [0002] With the higher and higher requirements for resolution, the application of high-end displays is becoming more and more extensive. High-end displays have higher requirements for color accuracy. At present, most of the colorimeters used to calibrate the color of the display use the CIE1931 coordinate system to measure the chromaticity of the display. However, the CIE1931 coordinate system is not suitable for the comparison calculation of human eye color vision, resulting in the problem of metamerism between different monitors even after color correction, so that users need to fine-tune the color after the monitor leaves the factory to obtain a consistent color. color output. In the prior art, the user adjusts the color by adjusting the gain and / or offset of RGB. However, this adjustment method will additionally af...
