Passive liquid crystal display screen with built-in touch function

Abstract

The invention relates to the technical field of liquid crystal display screens, in particular to a passive liquid crystal display screen with a built-in touch function. The passive liquid crystal display screen comprises a liquid crystal display, wherein a fixing mechanism is arranged on the liquid crystal display, two locking mechanisms are arranged in the fixing mechanism, two supporting mechanisms are arranged on the fixing mechanism, two clamping mechanisms are mounted in the fixing mechanism, a take-up mechanism is mounted on the fixing mechanism, and a limiting mechanism is arranged in the take-up mechanism. According to the invention, the fixing mechanism is used for fixedly mounting the liquid crystal display under the action of the locking mechanisms, so the liquid crystal display is protected; and a cable used by the liquid crystal display is conveniently rolled and stored under the action of the take-up mechanism, and the length of the cable is conveniently adjusted under the action of the limiting mechanism, so connection with external equipment and use of the passive liquid crystal display screen are facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display screens, in particular to a passive liquid crystal display screen with a built-in touch function. 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, and it is more convenient to operate by installing a touch screen function. , In the factory production, it is necessary to use the touch-sensitive liquid crystal display to facilitate the display of the functional structure and production method of the product through videos and pictures, thereby improving the quality of production. [0003] However, traditional liquid crystal displays are borderless displays that are relatively thin, and are prone to bumps during factory use, causing damage to the corners of the disp...

AI Technical Summary

Problems solved by technology

[0003] However, traditional liquid crystal displays are borderless displays that are relatively thin, and are prone to bumps during factory use, causing damage to the corners of the display, which affects the use of the display. At the same time, it is inconvenient to adjust the length of the wire when connecting the wires. At the same time, the cables are not easy to store and store, and the wires are easy to leak, and the staff are easy to stumble, fall, pull and damage when walking back and forth, which is likely to cause safety hazards
