Claim:
1. A luminance-chrominance calibration production line system of LED display module, comprises: a rail; a plurality of stations, disposed along the rail and comprising a plurality of first darkroom stations; a plurality of image acquisition apparatuses, respectively disposed in the plurality of first darkroom stations and configured for respectively capturing different color images sequentially displayed by a to-be-calibrated LED display module loaded on the rail in a pipelined manner so as to acquire color image data and thereby each of the plurality of image acquisition apparatuses capturing one type of the different color images; and a rail computer system, configured for controlling a transport movement on the rail and for controlling the to-be-calibrated LED display module to display the different color images, and being signally connected with the plurality of image acquisition apparatuses to obtain the color image data; wherein a time length from the rail being stopped from transporting the to-be calibrated LED display module entering each of the plurality of first darkroom stations to the rail being started for transporting again serves as an image capturing time of the first darkroom station, and the image capturing times of the plurality of first darkroom stations are set to be equal; and wherein the plurality of stations further comprise a warming up station set disposed before the plurality of first darkroom stations, a number of warming up stations in the warming up station set is determined by a time of the to-be-calibrated LED display module being needed to be warmed up, a transport time between neighboring warming up stations and the image capturing time, so as to ensure each the to-be-calibrated LED display module has a same warming up time.
