Abstract
A testing method and a testing apparatus for splicing screens (1, 2, 3, 4) are provided. The method includes: outputting an image signal to a display screen, wherein the display screen includes a plurality of splicing screens (1, 2, 3, 4), the image signal includes a plurality of testing sub pictures, the testing sub pictures are arranged correspondingly to the splicing screens (1, 2, 3, 4) so as to enable the splicing screens (1, 2, 3, 4) to display the corresponding testing sub pictures, and the testing sub pictures include testing contents (5, 6, 7, 8, 9, 10, 11, 12); and testing the splicing screens (1, 2, 3, 4) through the testing contents (5, 6, 7, 8, 9, 10, 11, 12). Testing on the splicing screens (1, 2, 3, 4) is achieved, and a testing result can be used for regulating the splicing screens (1, 2, 3, 4), so that defects generated in the displaying process of the splicing screens (1, 2, 3, 4) are reduced.
