Abstract
The utility model discloses a colored membrane foundation plate of a liquid crystal display device through a plurality of implementation methods. The colored membrane foundation plate comprises a glass foundation plate, wherein, colored resin is deposited on one surface of the glass foundation plate, transparent electrode indium-tin oxide is deposited on the other surface of the glass foundation plate, and a static electricity discharging layer with the conductivity factor higher than the conductivity factor of the transparent electrode indium-tin oxide is deposited in the edge area of the glass foundation where the transparent electrode indium-tin oxide is deposited. The static electricity discharging layer adopts a metal layer, and the material adopts Al, Cu, Au or Ag. The width of the static electricity discharging layer is 50 um. The utility model adopts the implementation methods that generated static electricity current can be quickly and uniformly diffused toward the periphery through the static electricity discharging layer with the conductivity factor higher than the conductivity factor of the indium-tin oxide when the ESD phenomenon emerges. Therefore, the implementation methods of the utility model not only eliminates the impact caused by the ESD, but also ensures a liquid crystal display panel to resume the normal working status immediately.
Description
Technical field
The utility model relates to a kind of transverse electric field mode LCD (Liquid Crysta1 Display, hereinafter to be referred as LCD) color membrane substrates, particularly a kind of have an elimination static discharge (ElectrostaticDischarge, hereinafter to be referred as ESD) the color membrane substrates of transparency electrode tin indium oxide (Indium Tin Oxide is hereinafter to be referred as ITO).
Background technology
In the module group procedure of fringe field switching technology (Fringe Fie1d Switching, be called for short FFS) mode LCD, because public electrode is on array base palte, and do not have public electrode on the color film, so color membrane substrates then is in the unprotect state, promptly can't eliminate ESD.
In order to make color membrane substrates be in guard mode; the scheme of prior art is that the antarafacial (one side that glass substrate deposits color resin is called the front of glass substrate, and another side is called the antarafacial of glass substrate) of the glass substrate in color membrane substrates is provided with ITO with the diffusion electrostatic induced current that ESD was produced.When the ESD phenomenon took place, the ITO on the color membrane substrates was by the independent release electrostatic electric current of ground structure of the frame (Bezel) at module edge, to eliminate the influence that ESD was produced.But, can not produce potential difference (PD) between ITO on the color membrane substrates of said structure and the ITO, can not rapid diffusion fall the static of accumulation.When the ESD phenomenon occurred in the FFS pattern, vertical by force electric field saw through substrate and disturbs original transverse electric field, causes the liquid crystal arrangement confusion.Liquid crystal is got back to original ordered state in this case needs for a long time, has caused display panels not work on immediately, promptly needs several minutes surge time in order to return to normal operating conditions.
The utility model content
The purpose of this utility model provides a kind of color membrane substrates of LCD, behind the electrostatic induced current that can snap-out release ESD phenomenon be produced, makes display panels return to normal duty immediately.
The utility model provides following technical scheme by some embodiments: the color membrane substrates that a kind of LCD is provided, described color membrane substrates comprises glass substrate, the one side of described glass substrate deposits color resin (Co1or Resin), the another side of described glass substrate deposits transparency electrode ITO, and the fringe region that deposits the described glass substrate of transparency electrode ITO deposits the electrical conductivity static releasing layer higher than the electrical conductivity of transparency electrode ITO.
Realize embodiment of the present utility model by the high static releasing layer of depositing electrically conductive coefficient ratio transparency electrode ITO around transparency electrode ITO, when the ESD phenomenon occurring, the electrostatic induced current that is produced can spread fast and equably towards periphery.Therefore, realize that embodiment of the present utility model not only can eliminate the influence that ESD caused, and make display panels can return to normal operating conditions immediately.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Embodiment
As shown in Figure 1, be the structural representation of the color membrane substrates embodiment of the utility model LCD.The color membrane substrates of present embodiment comprises glass substrate 10, the one side of glass substrate 10 deposits color resin 11, the another side of glass substrate 10 deposits transparency electrode ITO 12, and the fringe region that glass substrate 10 deposits the one side of transparency electrode ITO deposits the electrical conductivity static releasing layer 13 higher than transparency electrode ITO 12.Because static releasing layer 13 is nontransparent material, so be arranged on the fringe region of glass substrate 10, above-mentioned fringe region belongs to the noneffective display area territory.
In the present embodiment, static releasing layer 13 can be metallic aluminium (A1) layer than high tens of times of the electrical conductivity of transparency electrode ITO, the critical size of inspection eventually (Final Inspection CriticalDimension is called for short FICD) of A1 layer is that width is 50 μ m, as shown in Figure 2.
1 layer of the metal A of the antarafacial fringe region deposition of the above-mentioned embodiment of the color membrane substrates of the utility model LCD by its glass substrate, according to A1 and ITO difference to the electric current rate of propagation, produce potential difference, make the transparency electrode ITO middle part electrostatic induced current that ESD produced to discharge fast and equably.
In addition, the static releasing layer in the present embodiment can also can reach above-mentioned effect equally for metallic copper (Cu), metallic gold (Au) layer or argent (Ag) layer.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned embodiments, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment is put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
