TFT liquid crystal display screen lightening test fixture

Abstract

The invention discloses a TFT liquid crystal display screen lightening test fixture, which comprises a fixture base, a TFT test board, a fixture platform, an adapter plate and a placement assembly forcarrying out a fixing test, wherein the fixture platform is arranged above the fixture base, the TFT test board used for testing a display screen is installed between the fixture platform and the fixture base, the TFT display screen is placed at the end of the fixture platform, an installation groove is formed in the end face, where one side of the TFT display screen is located, of the fixture platform, an installation base is arranged in the installation groove, and the adapter plate is arranged above the installation base. The test fixture is in contact with a TFT liquid crystal display screen connector through a probe for testing. The rotary buckling mode is very convenient during connection. Moreover, the probe is not liable to be damaged during testing and can be continuously used, the testing efficiency is greatly improved, and the labor cost is saved. Meanwhile, a pushing plate can be buckled along with the adapter plate to protect the product connector, so that a good dustproof effect is achieved, the testing of the display screen is not affected at the same time, and the practical effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of TFT display screen testing, in particular to a lighting test fixture for a TFT liquid crystal display screen. Background technique [0002] TFT refers to thin-film transistor, which means that each liquid crystal pixel is driven by a thin-film transistor integrated behind the pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved, and it is currently the best LCD color One of the display devices, its effect is close to the CRT display, and it is the mainstream display device on notebook computers and desktops. Each pixel of the TFT is controlled by the TFT integrated on itself, which is an active pixel. Therefore, not only the speed can be greatly improved, but also the contrast and brightness are greatly improved, and the resolution has also reached a very high level.

AI Technical Summary

Problems solved by technology

[0003] At present, the TFT LCD screens on the market need to be tested many times during the production and assembly process, and because there are too many pins, the corresponding connector has a small PIN space, whether it is a board-to-board connector or a flip-up connector. During the test, the connection is difficult, the efficiency is low, and the test buckle is very easy to damage, and the dust falling on the connection seat will also cause the product to be mis-tested, and the test buckle is damaged. Professional welding personnel are required to replace it , sent out for repair, which leads to the trouble of using no test fixture
