[0002] As a multimedia display terminal, the display effect of LED display is an important indicator to measure its quality, among which the uniformity of brightness display is the top priority. Due to the discreteness and attenuation of light-emitting diodes, LED display screens often have the problem of uneven brightness display, which seriously affects the display effect. In order to overcome this problem, the point-by-point brightness correction technology of LED display screens came into being and developed rapidly, greatly improving the display quality. At present, the industry often uses imaging colorimeter body to detect and correct the brightness of LED display screens.
