Static discharge protector for liquid crystal screen

Abstract

Disclosed is a static discharge proof device on liquid crystal screen which comprises: a liquid crystal display module which is placed on a metal covering of tip with toothing-type flange and is packaged with shell body. Wherein, the metal covering of toothing-type tip can prevent statistic charge accumulation and release large amount of suddenly incoming statistic charge to prevent statistic charge from entering into liquid crystal screen via slit on electronic device, also, prevent electromagnetic wave from interfering liquid crystal display module and related circuits.

Description

technical field [0001] The present invention relates to an electrostatic discharge protection device related to a liquid crystal display, in particular to an electronic device including a liquid crystal display using a flange design of an additional metal cover to prevent static electricity from accumulating or releasing a large amount of sudden intrusion of external static electricity. Background technique [0002] Electrostatic discharge is the flow of an accumulated electrostatic charge from an area of ​​high electrostatic charge concentration to an opposite or low charge concentration area. The screen and driving components of the LCD screen module itself may be damaged or affected by static electricity. Electrostatic discharge damages the LCD screen module, such as screen defects, metal wiring is dissolved or evaporated, component resistance changes, oxide layer is destroyed or broken down, etc., and affects electronic circuits or controllers centered on microprocessors...

AI Technical Summary

Problems solved by technology

[0005] As a result, the resolution of the display screen of the mobile phone is required to be increased, which will lead to smaller indium tin oxide (ITO) wires of the liquid crystal display screen, and relatively weaken the protection ability of the mobile phone against electrostatic discharge.

Generally speaking, electrostatic discharge mostly intrudes into the ITO wire through the seam of the mobile phone mechanism, causing damage or crash of the LCD module.

[0006] In particular, the upper board of mobile phones usually includes a surface lens, and the edge of the surface lens is mostly coated with a metal layer. When the electrostatic discharge reaches the metal plating layer of the surface lens, it is easy to damage the overall liquid crystal display through the ITO on the liquid crystal panel. panel

[0007] Therefore, the existing technology includes adding capacitance or antistatic components on the glass, but this method often has the problem of glass breaking when bonding components.
