Integrated black liquid crystal display module testing tool

Abstract

The invention discloses an integrated black liquid crystal display module testing tool which comprises a rack and an operation table, the operation table is horizontally arranged over the rack, the size of the operation table is larger than that of the rack, a damping support is fixedly installed between the rack and the operation table, a testing table and a lifting base are arranged on the operation table, and the lifting base comprises an L-shaped rack. A fixing plate is fixedly installed on the rack, an adjusting plate is arranged at one end of the fixing plate, the adjusting plate and the fixing plate are rotatably installed through a rotating shaft, a baffle is vertically and fixedly installed at the other end of the rack, an electric telescopic rod is fixedly installed on the inner side of the baffle, and a supporting push plate is connected to the tail end of the electric telescopic rod and movably installed with the adjusting plate. A sliding groove is integrally formed in the rack, the supporting push plate is installed in the sliding groove in a sliding mode through a sliding block, the lifting base comprises a sleeve fixedly installed on the testing table and a lifting rod movably installed in the sleeve, an equipment bin is arranged below the rack, and heat dissipation holes are formed in the portions, on the two sides of the equipment bin, of the side wall of the rack.

Description

technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an integrated black liquid crystal display module testing tool. Background technique [0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses current to stimulate liquid crystal molecules to generate points, lines, and surfaces to form a picture with the back lamp tube. IPS, TFT, and SLCD are all subcategories of LCD. Its working principle is that under the action of an electric field, the alignment direction of the liquid crystal molecules is changed to change (modulate) the light transmittance of the external light source to complete the electro-optical conversion, and then use the different excitations of the R, G, and B three primary color signals , through the red, green, and blue three primary color filter films, the color reproduction in the time domain and space domain is completed. LCD (L...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of integrated black liquid crystal display module testing tool, to solve the problem that the production of the liquid crystal display proposed in the above-mentioned background technology must first use the liquid crystal display module testing tool to check its quality on the production line before leaving the factory. Inspection, the traditional LCD module test tooling has a simple structure, most of which are fixed structures, it is inconvenient to operate, and it is difficult to meet the actual test needs, and the traditional LCD module test tooling has a single function and a relatively small scope of application.
