METHOD AND DEVICE FOR TESTING SPLICED SCREEN

摘要

A method and device for testing a spliced screen (1, 2, 3, 4). The method comprises: outputting an image signal to a display screen, wherein the display screen comprises a plurality of spliced screens (1, 2, 3, 4), the image signal comprises a plurality of testing sub-pictures, the testing sub-pictures are arranged corresponding to the spliced screens (1, 2, 3, 4) for the spliced screens (1, 2, 3, 4) to display the corresponding testing sub-pictures, and the testing sub-pictures comprise testing content (5, 6, 7, 8, 9, 10, 11, 12); and the spliced screens (1, 2, 3, 4) are tested by the testing content (5, 6, 7, 8, 9, 10, 11, 12). The spliced screens (1, 2, 3, 4) are tested, and a testing result can be applied to the adjustment of the spliced screens (1, 2, 3, 4), thereby reducing poor quality occurring in the display process of the spliced screens (1, 2, 3, 4).
