Novel jig facilitating detection of liquid crystal display screen

Abstract

The invention discloses a novel jig facilitating detection of a liquid crystal display screen. The jig comprises a flip cover and base, wherein a connecting seat is fixedly mounted at the bottom of the flip cover; a mounting block is fixedly mounted on one side of the base; an upper groove is formed in one side, close to the base, of the flip cover; a lower flange is arranged on the front face ofthe side, close to the flip cover, of the base; the lower flange and the upper groove are used in cooperation; a PCB is fixedly installed between the upper groove and the lower flange; a positioning block is fixedly installed on the edge of the front face of the base, and installation holes are formed in one side of the base and a corresponding side of the flip cover. According to the novel jig facilitating detection of the liquid crystal display screen, through mutual cooperative use of the upper groove, the lower flange, a positioning guide column, the positioning hole and the positioning block, the situation that a detector senses the position of a connector manually in the detection process of the device is avoided; the accuracy of connection between the connectors is ensured, meanwhile, the overall production efficiency of the device is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display detection, in particular to a new fixture for convenient detection of liquid crystal display. Background technique [0002] Liquid Crystal Display (LCD) A type of display used in digital clocks and many portable computers. An LCD display uses two sheets of polarized material with a solution of liquid crystals between them. Passing an electric current through the liquid causes the crystals to rearrange so that light cannot pass through them, therefore, each crystal is like a shutter, which can not only allow light to pass through but also block light. Liquid crystal display (LCD) current scientific and technological information products are all moving towards light, thin, short and small goals. Development, display products with a long history in computer peripherals are no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT imag...

[0002] Liquid Crystal Display (LCD) A type of display used in digital clocks and many portable computers. An LCD display uses two sheets of polarized material with a solution of liquid crystals between them. Passing an electric current through the liquid causes the crystals to rearrange so that light cannot pass through them, therefore, each crystal is like a shutter, which can not only allow light to pass through but also block light. Liquid crystal display (LCD) current scientific and technological information products are all moving towards light, thin, short and small goals. Development, display products with a long history in computer peripherals are no exception. Under the premise of being easy to carry and transport, traditional display methods such as CRT image tube displays and LED display panels, etc., are limited by excessive size or Due to factors such as huge power consumption, the actual needs of users cannot be met, and the development of liquid crystal display technology is just in line with the current trend of information products. Whether it is a right-angle display, low power consumption, small size, or zero radiation, etc. Allow users to enjoy the best visual experience

[0003] Existing liquid crystal display inspection fixtures mainly rely on on-site inspection personnel to manually perceive the position of the PCB interface on the screen, and then connect the detection PCB interface to it. This detection method requires high proficiency of the inspection personnel and low detection efficiency. And there is an unstable connection of the detection interface, resulting in no improvement in production efficiency, and even increased production costs and product failure rates. Therefore, we propose a new type of fixture that is convenient for liquid crystal display detection.
