Embodiment Construction
[0021] The specific implementations of the method and system for compensating local brightness and chromaticity of a display device according to the present invention will be described in detail below with reference to the accompanying drawings.
[0022] see figure 1 , figure 1 It is a flow chart of a method for compensating local brightness and chroma of a display device according to an embodiment.
[0023] A method for compensating local brightness and chromaticity of a display device, comprising the following steps:
[0024] Step S101: select several pixel points of the display device as specified points, adjust the brightness reference value Z of the four-color RGBW of each specified point, and obtain the adjusted brightness reference value Z R1 , brightness reference value Z G1 , brightness reference value Z B1 , brightness reference value Z W1 ; Wherein, the brightness reference value Z includes the brightness reference value Z R , brightness reference value Z G ,...

The invention provides a method and a system for locally compensating the brightness and the chrominance of display equipment. The method comprises the following steps of selecting a plurality of pixel points of the display equipment as specified points, adjusting the brightness reference value Z of four colors RGBW (red, green, blue and white) of each specified point, and calculating to obtain a target brightness reference value of each color according to the brightness reference value ZR1, the brightness reference value ZG1, the brightness reference value ZB1 and the brightness reference value ZW1 which are obtained through adjustment; according to the target brightness reference value of each color of RGB (red, green and blue), the maximum value and the minimum value of the semaphore of each color, and the maximum value and the minimum value of the target brightness reference value of each color, calculating to obtain the semaphore corresponding to each color of the RGB of the specified points; according to the semaphores of the RGB of the specified points, calculating through an interpolation algorithm to obtain the corresponding semaphore of each pixel point of the display equipment. Due to the fact that when uniformity adjustment is performed during local brightness and chrominance compensation by only adjusting the size of the brightness reference value Z of the pixel points, the uniformity correction operation on the display equipment is relatively simple.
Description
technical field [0001] The present invention relates to the field of display device display technologies, in particular to a method for compensating local brightness and chroma of a display device and a system for compensating local brightness and chroma of a display device. Background technique [0002] At present, display devices are widely used, including handheld terminals, personal use terminals, etc. At the same time, display devices of different sizes and types can also be used in a wide range of occasions such as public exhibitions and performances. The display effect of the display device is the part that people are most concerned about in actual use, and the brightness and chromaticity uniformity of the display device greatly affect the display effect of the user, so one of the current development trends of the display device is to improve the uniformity of the display At present, there are many uniformity adjustment methods, but the uniformity correction operation...
