Description

technical field [0001] The invention relates to the field of display module testing, in particular to a system and method for automatically measuring optical data of a liquid crystal display module. Background technique [0002] In the production process of liquid crystal display modules, it is necessary to test the brightness, uniformity, color coordinates, contrast, color saturation, Gamma, Crosstalk, afterimage test and other parameters of the liquid crystal display module. Most of the measurements are usually performed manually by the operator, which is inefficient. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The object of the present invention is to overcome the deficiencies of the prior art and provide a system and method for automatically measuring optical data of a liquid crystal display module. [0005] The technical scheme of the present invention is as follows: the present invention provide...
