Problems solved by technology
[0004] However, the color analyzer is not only expensive, but also the product model of the color analyzer is greatly constrained in the process of display Flicker value adjustment, P-gamma correction adjustment, and De-Mura, which is reflected in the short working distance between the color analyzer and the display screen , to be measured against the light-emitting surface of the display
The inability to work remotely makes the measurement process must be strictly serial: first adjust the Flicker value, then adjust the P-gamma correction, and then perform the photographing and repairing of the De-Mura process. The serial adjustment operation process is for the shooting equipment to adjust on the display The improvement of efficiency has brought about a bottleneck, which reduces the efficiency of display adjustment

The embodiment of the present application discloses a method for generating a brightness measurement model of a display screen and a related device, which are used to improve the adjustment efficiency of a display screen. The method in the embodiment of the present application includes: setting the working parameters and the calibration environment; controlling the spherical integral standard light source to output the light source, and using the camera and the color analyzer to take pictures; calculating the average gray value; according to the first calibration gray average value data and Refer to the brightness value data for fitting; generate a shooting distance set according to the initial shooting distance and moving step; control the spherical integral industrial light source to output the distance brightness value set; control the shooting camera to move according to the shooting distance set and shoot the spherical integral industrial light source ;Calculate the gray average value of the second calibration shooting image set; calculate the target attenuation coefficient according to the second calibration gray scale average value data and the shooting distance set; generate the second photometry of the shooting camera according to the target attenuation coefficient and the first photometry model Model.
Description
technical field [0001] The embodiments of the present application relate to the field of display screens, and in particular to a method for generating a brightness measurement model of a display screen and related devices. Background technique [0002] The brightness measurement of the display screen is a professional optical conversion process, and the measurement results need to be compared with the corresponding international standards of CIE. Therefore, professional luminance measuring instruments are all strictly calibrated special optical instruments. Among them, the color analyzer is an instrument that plays an important role in each testing process of the display screen. In the mass production process, most display screens usually go through Flicker value adjustment, P-gamma correction adjustment, and De-Mura process. The testing equipment for these processes are all assembled on a shooting device, which includes a color analyzer . [0003] Taking the P-gamma corre...
