Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail. It should be appreciated that detailed description of the invention described herein is merely to illustrate and explains the present invention, it is not limited to the present invention.
The present invention provides a kind of display base plate, and provides its embodiment. Fig. 1 is the schematic diagram of display base plate in embodiment of the present invention; Fig. 2 is the schematic diagram of static discharge unit. As shown in Figures 1 and 2, in the present embodiment, described display base plate 1 includes multiple static discharge unit 2, and described static discharge unit 2 includes the first conductive pattern 21 and the second conductive pattern 22 being oppositely arranged.
Specifically, it is shown that display base plate 1 can for the array base palte of display panels or to box substrate (colored filter at display panels is typically prepared to time on box substrate, also referred to as color membrane substrates). The electric conductor arranged on array base palte is more, such as can there be grid line (grid of thin film transistor (TFT) can be considered a part for grid line and be included in the present embodiment), data wire (source electrode of thin film transistor (TFT) and drain electrode can be considered a part for data wire and be included in the present embodiment), public electrode wire and the electric conductor such as pixel electrode, public electrode, when there is Electro-static Driven Comb, it is easily caused short circuit etc., causes the damage showing bad or display floater. To box substrate is also equipped with electric conductor, such as black matrix, when there is Electro-static Driven Comb, will also result in adverse consequences.
When display base plate 1 produces electric charge, and when gathering, existence due to the first conductive pattern 21 and the second conductive pattern 22, described electric charge is easily transferred on the first conductive pattern 21 and the second conductive pattern 22, thus the electric charge that other regions reduced on display base plate are gathered, reduce the probability that Electro-static Driven Comb occurs in other regions of display base plate.Again owing to the first conductive pattern 21 and the second conductive pattern 22 are oppositely arranged, it is transferred to the electric charge on the first conductive pattern 21 and the second conductive pattern 22 easily to discharge between the first conductive pattern 21 and the second conductive pattern 22 and consume, so that the overall electric charge gathered reduces on display base plate, the final purpose realizing the electrostatic defending to display base plate. Even and if a certain region on display base plate, because there is Electro-static Driven Comb and short circuit between first conductive pattern 21 and second conductive pattern 22 of one static discharge unit, cause that this static discharge unit lost efficacy, but the quantity of the static discharge unit owing to arranging on display base plate is multiple, other static discharge unit not lost efficacy still are able to provide electrostatic defending to display base plate.
Preferably, the first conductive pattern 21 of described static discharge unit 2 is identical with the area of the second conductive pattern 22. According to experiments show that, it is easier to discharge between two conductive patterns that area is close, therefore, in the present embodiment, it is identical with the area of the second conductive pattern 22 that the first conductive pattern 21 in static discharge unit 2 is set, the probability that generating occurs between the first conductive pattern 21 and the second conductive pattern 22 can be improved, be more beneficial for realizing consuming electrostatic charge this purpose on display base plate.
Specifically, described static discharge unit 2 is arranged on the marginal area (region that namely dotted line institute frame goes out in Fig. 1) of described display base plate 1. On the one hand, when exterior static electric charge enters in display base plate 1, need to through marginal area, at this moment it is easy for being arranged on the first conductive pattern 21 of marginal area and the second conductive pattern 22 absorbs, without entering into the interior central area of display base plate 1, it is possible to effectively protect holding wire and the electrode etc. of interior central area do not occur because of Electro-static Driven Comb bad or damage; On the other hand, marginal area is not used in display, for non-display area, arranges the first conductive pattern 21 and the second conductive pattern 22 without influence on display.
Distance between described first conductive pattern 21 and second conductive pattern 22 of each static discharge unit 2 is not more than 10 microns. The distance being appreciated that between the first conductive pattern 21 and the second conductive pattern 22 is more little, more easily discharges therebetween; Distance between first conductive pattern 21 and the second conductive pattern 22 is more big, is less susceptible to therebetween electric discharge. The distance arranged between the first conductive pattern 21 and the second conductive pattern 22 is not more than 10 microns, it is possible to avoid the first conductive pattern 21 and the second conductive pattern 22 therebetween because occurring apart from the excessive situation being difficult to discharge.
Specifically, described first conductive pattern 21 and the second conductive pattern 22 all include base portion a and on described base portion a spaced multiple teeth portion b; As in figure 2 it is shown, the base portion a of the base portion a of described first conductive pattern 21 and the second conductive pattern 22 is relative, multiple teeth portion b of the first conductive pattern 21 and multiple teeth portion b of the second conductive pattern 22 are crisscross arranged. Structure according to Fig. 2, area relative to each other between the first conductive pattern 21 and the second conductive pattern 22 is bigger, it is possible to make to be easier to discharge between the first conductive pattern 21 and the second conductive pattern 22.
It should be noted that, in the present embodiment, shown display base plate is possible not only to into the array base palte of display panels or to box substrate, in addition, shown display base plate can also be AMOLED display base plate, based on principle same as described above, it is arranged on the static discharge unit on described AMOLED display base plate and can provide electrostatic defending to AMOLED display base plate.
In sum, the display base plate that embodiment of the present invention provides, it is transferred on the first conductive pattern 21 and second conductive pattern 22 of static discharge unit 2 by the electrostatic charge being produced inside or externally entering, and between the first conductive pattern 21 and the second conductive pattern 22, form electric discharge, thus electrostatic charge is consumed; Electrostatic charge in final display base plate reduces, and the release of electrostatic occurs between the first conductive pattern 21 and second conductive pattern 22 of static discharge unit 2 rather than occurs in other regions of display base plate, such that it is able to the short circuit avoiding the occurrence of the electric conductor such as holding wire and electrode in other regions of display base plate and the adverse consequences caused therefrom.
