By setting an inclined panel, a sealing frame, an elastic fixing component and a limit frame, a display screen is placed in the limit frame, and the display screen is positioned so that the display screen is placed in the sealing frame and the color difference of the display screen can be detected by a color difference detection device. Moreover, continuous detection operation can be achieved by alternately switching positions of two limit frames in the sealing frame. However, when the LED display screen color difference detection device is detecting the display screen, it is necessary to manually push the handle to transport the limit frame into the sealing frame for color difference detection, and manually pull out and then take the display screen out from the inside, which increases the manual workload and reduces the work efficiency. At the same time, the display screen color difference detection device is embedded and installed inside the support table. If the detection device fails, it is not convenient to repair it.
