Abstract

The invention discloses a method and a device for testing a splice liquid crystal display. The method comprises the following steps: outputting an image signal to a display screen comprising a plurality of splice liquid crystal display, wherein the image signal comprises a plurality of testing sub-images which are arranged corresponding to the splice liquid crystal displays so as to enable the splice liquid crystal displays to display the corresponding testing sub-images, and the testing sub-images comprise testing contents; and testing the splice liquid crystal displays by the testing contents. By the technical scheme, the splice liquid crystal displays are tested, and the testing result can be applied to adjusting the splice liquid crystal displays, so that badness generated in the display process of the splice liquid crystal displays is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a testing method and testing device for a splicing screen. Background technique [0002] The splicing screen is a complete display unit, which can be used as a display alone or spliced ​​into a large screen. According to different usage requirements, the display screen formed by the splicing of the splicing screen can realize the ever-changing function of becoming larger or smaller. The display screen is a complete finished product, ready to use, and the installation is as simple as building blocks. The splicing and installation of single or multiple splicing screens are very simple, which meets the needs of customers for various sizes of display screens. [0003] In the prior art, the splicing screen is put into use after splicing to form a display screen, and no test is performed on the splicing screen in the display screen before it is put into use, resulting in various disp...
