Can quicken the electrostatic prevention liquid crystal display screen of electrostatic dissipation

Technical field

The utility model relates to the LCDs technical field, relates in particular to a kind of electrostatic prevention liquid crystal display screen that quickens electrostatic dissipation.

Background technology

Advantage such as that LCDs has is in light weight, thin thickness, volume are little has been widely used on the various electronic equipments.General LCDs is mainly by two glass substrates that are parallel to each other, be provided with envelope frame glue around between the two sheet glass substrates, two sheet glass substrates and the sealing of envelope frame glue form airtight inner chamber, be filled with liquid crystal in the airtight inner chamber, the medial surface of two sheet glass substrates is provided with ITO (the Indium Tin Oxides that is used for the display pixel pattern, the nano indium tin metal oxide) walks line electrode, after the electrifying electrodes between two sheet glass substrates, can form electric field between two sheet glass substrates, and then influence the arrangement of liquid crystal, cause covering or reversing of light, realize corresponding display effect.

Because glass substrate is usually located at the outermost of LCDs and the characteristic of the manufactured materials of glass substrate own, make the glass substrate of LCDs, in production or use, all be very easy to assemble electric charge, and generation static, electrostatic potential can reach several kilovolts, electrostatic potential can form bigger electrostatic induction electric field between two sheet glass substrates, liquid crystal ordered state under the electrostatic induction effect of electric field can change, and then influence display frame (being that static shows), even damage LCDs.The electrostatic prevention liquid crystal display screen of prior art, be in liquid crystal, to add some antistatic agent or adopt antistatic material mostly, though this way can reduce the generation of static, but can't thoroughly eliminate static, static still can be residual than the long time, LCDs is caused certain infringement, and antistatic agent or antistatic material cost an arm and a leg usually, the production cost of LCDs is greatly increased.

The utility model content

The purpose of this utility model is to provide at the deficiencies in the prior art the electrostatic prevention liquid crystal display screen of low the quickened electrostatic dissipation of a kind of production cost.

The purpose of this utility model realizes by following technical measures: a kind of electrostatic prevention liquid crystal display screen that quickens electrostatic dissipation, it includes two glass substrates that are parallel to each other, be provided with envelope frame glue around between the two sheet glass substrates, two sheet glass substrates and the sealing of envelope frame glue form airtight inner chamber, be filled with liquid crystal in the airtight inner chamber, the medial surface of two sheet glass substrates is provided with the ITO that is used for the display pixel pattern and walks line electrode, the white space of the medial surface of described two sheet glass substrates is filled with the ITO conducting block of the static that is used to dissipate, and ITO conducting block and ITO walk and be provided with the gap between the line electrode.

The lateral surface of described two sheet glass substrates all is fitted with polaroid.

Described two sheet glass substrates and the sealing of envelope frame glue form in the airtight inner chamber and are filled with sark.

Described ITO walks line electrode and is connected with conductive electrode.

The thickness of described glass substrate is 0.3～1.1 millimeter.

The utility model beneficial effect is: the utility model includes two glass substrates that are parallel to each other, be provided with envelope frame glue around between the two sheet glass substrates, two sheet glass substrates and the sealing of envelope frame glue form airtight inner chamber, be filled with liquid crystal in the airtight inner chamber, the medial surface of two sheet glass substrates is provided with the ITO that is used for the display pixel pattern and walks line electrode, the white space of the medial surface of two sheet glass substrates is filled with the ITO conducting block of the static that is used to dissipate, and ITO conducting block and ITO walk and be provided with the gap between the line electrode; Because the white space of the medial surface of glass substrate, the zone that ITO walks line electrode promptly is not set, expose, be easy to assemble electric charge, produce static, and the very difficult mobile and dissipation of the electric charge of assembling, and the ITO conducting block that the utility model is filled at these white spaces, can rapidly the gathering electric charge be led away and dissipate, reach the purpose of electrostatic prevention.Therefore, the utility model can quicken the dissipation of static, and anti-static effect is good, production cost is low.
