Description
Technical field
The utility model relates to LCDs technical field, particularly relates to a kind of Anti-static liquid crystal display screen.
Background technology
Along with the development of display technique, touch display screen is applied in various with on the equipment of Presentation Function more and more widely.LCD screen is as principal display device, be widely used in the numerous areas such as national defence, industry, family expenses, communal facility, current display requires more and more higher: the operating temperature range that volume is little, wider as far as possible, low-power consumption, wider angular field of view, show various word.Traditional liquid crystal display, adopt SMT structure, need controller IC, memory IC, driver IC, DC/DC power-switching circuit IC, bias circuit, temperature-compensation circuit etc., in production or use procedure, all be very easy to assemble electric charge, and produce electrostatic, electrostatic potential can reach several kilovolts, electrostatic potential can form larger electrostatic induction electric field between LCD screen two panels glass substrate, liquid crystal ordered state under the effect of electrostatic induction electric field can change, and then there is the improper display of pen section (i.e. electrostatic display), even damage LCDs.Electrostatic the opto-electronic industry such as microelectronics and the LCD producer can be described as hundred evil and none is sharp.China is every year because electrostatic cannot use statistics far away in the loss of the opto-electronic industry such as microelectronics and LCD.Cause photoelectron display industry cost thus to remain high, product fraction defective is high, the adverse consequences that the defective products scrappage in semi-manufacture is high.
In order to prevent electrostatic charge on the impact of LCDs, usually on common liquid crystals display screen basis, the conductive ion adding trace in originally common liquid crystal molecule material, when the external world occurs with high-tension static charge buildup, conductive ion in liquid crystal molecule can in and positive and negative charge, offset a large amount of gathering of static charge and produce higher voltage appearance, thus there is certain antistatic effect.But the antistatic agent added in its liquid crystal material of the product of said structure can affect the display effect of LCDs; And antistatic effect is limited, the ability of institute's electrostatic prevention but can only reach about 8KV at most, can not meet the product demand of high request.
Utility model content
The purpose of this utility model overcomes above-mentioned deficiency of the prior art, provides a kind of structure simple, possess the LCDs of good antistatic effect.
The purpose of this utility model is achieved through the following technical solutions:
A kind of Anti-static liquid crystal display screen, comprise surface glass substrate, end glass substrate and the sealed plastic box be arranged between surface glass substrate and end glass substrate, sealed plastic box is by face, surrounding between end glass substrate seals, make face, end glass substrate and sealed plastic box sealing form sealed internal chamber, it is characterized in that: in described sealed internal chamber, be filled with electrostatic prevention liquid crystal molecule, the inner side of described surface glass substrate is coated with the ITO conducting film as electrode wires, the outside of described surface glass substrate is provided with the 2nd ITO conducting film be connected with shell, the inner side of end glass substrate is coated with the 3rd ITO conducting film as electrode wires.
Concrete, described Anti-static liquid crystal display screen also comprises face polaroid, end polaroid, and face, end polaroid fit in face, end glass substrate respectively.
Preferably, the thickness of described glass substrate is 0.4 ~ 1.2 millimeter.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model inside and outside both sides on the surface glass substrate of conventional LCD device are all coated with ITO conducting film, ito film wherein in liquid crystal cell is used as electrode wires, full wafer ITO conducting film outside liquid crystal cell has electric action, can be dispersed by the ITO conducting film of full wafer when extraneous static lotus assembles in a large number, be unlikely to accumulation and produce high voltage at a certain position, thus play and greatly reduce electrostatic interaction, when LCD is assembled on complete machine, the full wafer ITO conducting film of surface glass substrate is connected with shell and plays evacuation charge effect, there is good antistatic effect, ± the electrostatic capacity of 15KV can be resisted after tested, antistatic effect significantly promotes.
2, the LCD of said structure is in normal use procedure, can't affect its display effect, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
