摘要： A method, a device and a system of detecting uniformity of thickness of a display screen are provided. The detecting method includes extracting preset brightness curves for each of moire stripes when the display screen displays a monocolour picture; calculating an average position coordinate in a preset direction for each of the preset brightness curves; calculating a deviation value of a position coordinate in the preset direction of discrete points on each of the preset brightness curves with respect to the average position coordinate; for each of the preset brightness curves, when the deviation value exceeds a preset allowable deviation range, determining a thickness abnormal position of the display screen according to the coordinates of the discrete points corresponding to the deviation values. By this detecting method, a thickness abnormal position of a display screen can be accurately detected, and the controllability of the products can be improved.
