Embodiment
For technical matters, technical scheme and advantage that embodiments of the invention will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiments of the invention provide a kind of horizontal electric field mode display panels, display device, the antistatic effect of the electric field patterns of can improving the standard display panels for the problem of display panels electrostatic prevention ITO imperfect earth in the prior art.
The embodiment of the invention provides a kind of horizontal electric field mode display panels, comprises color membrane substrates and array base palte, is provided with transparency conducting layer on the described color membrane substrates, and described transparency conducting layer is connected with earth point on the described array base palte by conductive structure.
Technical scheme of the present invention is applicable to existing horizontal electric field mode display panels, and the structure of color membrane substrates is not limited.
Further, described color membrane substrates comprises the black Matrix Pattern that is formed on the substrate, and described transparency conducting layer is between described substrate and described black Matrix Pattern.
Further, described conductive structure can comprise the conductive projection that is arranged on the described color membrane substrates, and this conductive projection is connected with earth point on the array base palte.Preferably, the position of conductive projection earth point on the position on the color membrane substrates and array base palte is corresponding, and conductive projection can directly be connected with earth point like this.
Further, conductive projection can also be connected with earth point by the ground wire that is arranged on the array base palte, conductive projection is can be not in the position on the color membrane substrates not corresponding with the position of earth point on the array base palte like this, has improved the dirigibility that the conductive projection position arranges.Particularly, ground wire can be via Driver IC(driving circuit) be connected to the GND(earth point on the printed circuit board (PCB)).
Further, in the such scheme, in order not affect display effect, conductive projection preferably is arranged on outside the viewing area of display panels.
Further, because in display panels, corner areas is to accumulate easily static, carries out the position of static discharge, therefore, described conductive projection preferably is arranged on the corner areas of display panels.
The horizontal electric field mode display panels of present embodiment, be provided for the transparency conducting layer of release electrostatic at color membrane substrates, this transparency conducting layer is near array base palte, and be connected with earth point on the array base palte by conductive projection, effectively avoided the problem of display panels electrostatic prevention ITO imperfect earth in the prior art, thereby improved the antistatic effect of display panels, can realize eliminating fully static, improve the picture quality of liquid crystal display, improved the yields of liquid crystal display.The present invention is applicable to the liquid crystal display of horizontal electric field mode, has broad application prospects.
