Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal display detection equipment, in particular to an LCD liquid crystal display electrical performance detection equipment. Background Technique

[0002] A liquid crystal display screen, abbreviated as LCD in English, is a type of flat panel display. It is used for the screen display of televisions and computers. The advantages of this display screen are low power consumption, small size, and low radiation. Liquid crystal display screens (LCDs) are a type of display used in digital watches and many portable computers. Currently, when producing liquid crystal display screens, detection equipment is required to detect the conductive performance of the liquid crystal display screens.

[0003] The existing Chinese patent with the publication number CN218825030U discloses a liquid crystal display screen detection device. The key points of its technical solution are as follows: including a base, a support seat, a fixture, and a cylinder. The support seat is installed at one end of the base. One end of the cylinder is detachably installed on the support seat, and the other end is fixedly connected to the fixture. For the above-mentioned liquid crystal display screen detection device, through the cooperative setting of the fixture and the cylinder, the liquid crystal display screen to be detected is placed in the fixture, and the cylinder controls the telescopic rod to move towards the fixture, applying pressure to the top of the fixture, so that the top of the fixture presses the joint part of the liquid crystal display screen and the conductive rubber strip to test the conductive performance of the liquid crystal display screen. By automatically pressing the conductive part of the liquid crystal display screen with the cylinder, manual pressing is avoided, the testing efficiency is improved, and the labor cost is saved.

[0004] The above-mentioned existing technical solution has the following defects. Although the above-mentioned technical solution avoids manual pressing through the automatic pressing of the conductive part of the liquid crystal display screen by the cylinder, improves the testing efficiency, and saves the labor cost, in the above-mentioned technical solution, when pressing the liquid crystal display screen on the fixture with the cylinder, the pressure is relatively large, which is likely to damage the liquid crystal display screen during the detection process, thus easily reducing its use effect.
