an lcd liquid crystal display

Abstract

The invention relates to an LCD liquid crystal display screen. The LCD liquid crystal display screen comprises a cabinet body and a lifting mechanism, a lifting mechanism is installed in the cabinet body in a sliding fit mode. According to the LCD liquid crystal display screen, the adjustable lifting design concept is adopted to use the LCD liquid crystal screen; the lifting mechanism is adopted to perform mechanical lifting control on the display screen; data lines in the display screen mounting cabinet are sorted by adopting a plurality of structures; a U-shaped plate is adopted to assist infixing the connection part of the data line; the loosening or falling phenomenon is reduced; the use performance of the display screen is further improved; the winding column provided by the invention can play a role in carding and arranging data lines; different data lines are prevented from being wound and knotted, the probability of influence on the movement of the display screen is reduced, the overall cleanliness is improved, and meanwhile, the winding column can automatically rotate in the reverse direction to tighten the data lines by virtue of the rotation force of the torsion spring,so that the data lines are prevented from loosening.

Description

technical field [0001] The invention relates to the field of display screen equipment, in particular to an LCD liquid crystal display screen. Background technique [0002] Liquid crystal is an organic compound composed of long rod-shaped molecules. In the natural state, the long axes of these rod-shaped molecules are roughly parallel. The liquid crystal screen uses liquid crystal material as the basic component, and fills the liquid crystal material between two parallel plates. Change the alignment of molecules inside the liquid crystal material by voltage to achieve the purpose of shading and light transmission to display images of different shades and patches, and only need to add a three-color filter between the two plates The structure of the LCD screen is to place liquid crystals in two parallel glasses. There are many small vertical and horizontal wires in the middle of the two glasses. The rod-shaped crystals are controlled by whether they are energized or not. Molec...

AI Technical Summary

Problems solved by technology

[0003] 1. Common lift-type LCD screens need to be adjusted manually one by one when they are in use. In the case of a large number of LCD screens, it is impossible to ensure that the inclination angle of each LCD screen is consistent, and it is a waste of manpower. The frequency of use of the screen is not high, and dust and other sundries are easy to accumulate on the surface of the screen. At the same time, dust and other sundries accumulate too much and easily enter the gaps on the screen, which affects the performance of the screen;

[0004] 2. There will be many data lines inside the lift-type LCD installation cabinet, and the data lines are prone to entanglement and knotting, making the inside of the installation cabinet in a messy state, which hinders subsequent inspection and maintenance. At the same time, the display During the screen lifting process, random scattered data lines are likely to form a mutual drag phenomenon, which will affect the movement of the display screen and other devices
