A Passive Matrix Driven Liquid Crystal Display

Abstract

The invention relates to the technical field of liquid crystal display equipment, and discloses a passive matrix driven liquid crystal display, which includes a base, an adjustment box is fixedly installed on the top of the base, a first motor is fixedly installed at one end inside the adjustment box, and The output end of the first motor is fixedly connected to one end of the worm, and the two ends of the worm are movable connected to the top of the support rod I fixedly installed inside the regulating box. The middle part of the worm meshes with the outside of the worm gear, and The middle part of the worm gear is fixedly connected with a support rod II. The passive matrix driven LCD display, through the joint action of the worm and the worm gear, makes it easy to adjust the angle of the LCD display, which can meet the different angles of people watching videos and improve the practicality of the LCD display. At the same time, the worm and the worm gear mesh with each other. The self-locking function prevents the LCD monitor from rotating randomly after being adjusted to a certain angle, improving the stability of the LCD monitor.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display devices, in particular to a passive matrix driven liquid crystal display. Background technique [0002] Liquid crystal display is a kind of flat-panel display, which is used for the screen display of televisions and computers. The advantages of this display are low power consumption, small size, and low radiation. The liquid crystal display uses two polarized materials A liquid crystal solution through which an electric current will rearrange the crystals for imaging purposes. [0003] The currently used liquid crystal display does not have an automatic cleaning function. For long-term use of the liquid crystal display, a large amount of dust is adsorbed on the surface of the liquid crystal display, which affects the cleanliness and viewing effect of the liquid crystal display. Moreover, the angle of the existing liquid crystal display can only be in the vertical direction. If you ...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a passive matrix driven liquid crystal display, which has the advantages of good cleaning effect, convenient cleaning and angle adjustment, and solves the problem that the currently used liquid crystal display does not have an automatic cleaning function, and the surface of the liquid crystal display is used for a long time due to electrostatic adsorption. Dust affects the cleanliness and viewing effect of the liquid crystal display, and the angle of the existing liquid crystal display can only be adjusted in the vertical direction. If you want to adjust the angle in the horizontal direction, you need to move the entire liquid crystal display, which is difficult to operate. It is cumbersome, and the fasteners need to be loosened and locked before and after the existing angle adjustment. The wear after long-term use leads to insufficient locking force of the fasteners, which reduces the stability of the LCD display.
