Description

Technical Field

[0001] The invention relates to the technical field of electrostatic discharge, in particular to an electrostatic discharge protection device for a liquid crystal display. Background Art

[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to generate dots, lines, and surfaces to form a picture with the back light tube. IPS, TFT, and SLCD are all subcategories of LCD. [1] Its working principle is that under the action of the electric field, the arrangement direction of liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used to complete the color reproduction in the time domain and space domain through the three primary color filters of red, green, and blue. Usually, static electricity may be generated in each process of the array substrate during the production process. When the static electricity in the array substrate accumulates to a certain extent, it often causes the pixel area to be damaged due to electrostatic discharge (ESD). When the size of the array substrate is small, its static electricity accumulation is relatively small, and the probability of electrostatic damage caused by ESD is low or can be ignored. However, as the size of the array substrate increases, the electrostatic damage caused by ESD will become more and more serious. Therefore, its ESD electrostatic protection is particularly important.

[0003] When the electrostatic discharge protection device of the liquid crystal display is in use, the static electricity is usually discharged by grounding discharge. However, when the static electricity is discharged by grounding, the weight of the static electricity grounding point cannot be increased. When the static electricity grounding point is easily affected by the weight, the bonding effect of the static electricity grounding point is reduced, thereby affecting the static electricity discharge effect. At the same time, when the electrostatic discharge protection device of the liquid crystal display is in use, the static electricity collection situation cannot be observed. As a result, when the device fails to collect static electricity, people cannot turn off the liquid crystal display in time to reduce the generation of static electricity. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides an electrostatic discharge protection device for a liquid crystal display. The device utilizes the sliding of an adjustment seat and a slide bar to push a plurality of adjustment seats toward the surface of a fitting seat. The device utilizes the fitting of a first rubber pad and a second rubber pad to make the adjustment seat, when moving, not easily slide on the surface of the slide bar by utilizing the friction between the first rubber pad and the second rubber pad. The device utilizes the weight of a weighted seat to make the weight of a grounding seat overall downward, so that the anti-skid pad can fit with the ground under the influence of the weight of the weighted seat, thereby increasing the fit between the grounding seat and the ground. When the grounding seat fits with the ground, the discharge end and the grounding seat can fit with the ground together, so that the grounding wire and the discharge end can conduct the static electricity in the electrostatic collector to the ground for discharge. The weight of the weighted seat makes it difficult for the grounding seat to have a gap with the ground, so that the discharge efficiency of the static electricity can be improved. The movement of the first reflective observation plate and the second reflective observation plate can adjust the distance between the first reflective observation plate and the second reflective observation plate. The cam is adjusted so that when the first reflective observation plate and the second reflective observation plate are tilted, the first angle adjustment movable plate and the second angle adjustment movable plate can be tilted and squeezed according to the tilt angle of the first reflective observation plate and the second reflective observation plate to adjust the distance between the first reflective observation plate and the second reflective observation plate. After the adjustment of the first reflective observation plate and the second reflective observation plate is completed, the movement of the bearing plate can be used to adjust the distance between the baffles, so that the engaging rod can be respectively engaged in the first angle adjustment movable plate and the second angle adjustment movable plate. The elasticity of the spring can be used to increase the diameter of the connection between the engaging rod and the first angle adjustment movable plate and the second angle adjustment movable plate to fix the first angle adjustment movable plate and the second angle adjustment movable plate. The first reflective observation plate and the second reflective observation plate can be used to expand the light displayed on the display, etc., which solves the problems of static grounding discharge effect and inconvenient observation of static electricity collection.
