| description | The utility model provides a liquid crystal display screen testing device, which relates to the technical field of display screens and comprises a testing box main body, the testing box main body is fixedly connected with a placing table, and the placing table is fixedly connected with a first electric-hydraulic push rod. According to the utility model, the second servo motor drives the first screw rod to rotate, the first screw rod drives the first sliding block to slide along the first sliding groove, and the first sliding block drives the second sliding groove and the second sliding block to move back and forth, so that the front-back position of the magnifying lens is adjusted; similarly, a first servo motor drives a second lead screw to rotate, and the second lead screw drives a second sliding block to slide along a second sliding groove, so that a magnifying lens is driven to move left and right, and the light-emitting points at the left and right positions of the display screen body are conveniently in |
