Specific embodiment
Further to illustrate the present invention to reach technological means and effect that predetermined purpose is taken, below in conjunction with accompanying drawing and preferred embodiment, the present invention is described in detail as after.
The touch LCD display that the present invention is provided, improves the efficiency of mobile phone assembling, and improves the service life of mobile phone.Touch LCD display of the invention and its all parts will be described in detail belows.
First embodiment
As depicted in figs. 1 and 2, the touch LCD display of the present embodiment includes mainboard 2, cover plate 1, upper polaroid 3, colored filter 7, thin film transistor (TFT) and down polaroid 11.
As shown in Figure 2：Mainboard 2 and cover plate 1 are oppositely arranged, and down polaroid 11, thin film transistor (TFT), color filer and upper polaroid 3 are sequentially stacked and placed on cover plate 1 from top to bottom, and between mainboard 2 and cover plate 1, form overlapping unit.Fig. 1 is that terminal is buckled in front view when being tested on testing stand, thus in fig. 2 cover plate 1 in bottom, mainboard 2 is in the top.Wherein, upper polaroid 3 is grounded, and the side of overlapping unit is provided with conductive strips 4 from upper polaroid 3 to thin film transistor (TFT).The side of overlapping unit can be the front side or rear side shown in left side or right side, or figure shown in figure, as long as conductive strips 4 can be provided with from upper polaroid 3 to thin film transistor (TFT) in the side of overlapping unit.
The electrostatic 12 that interior of mobile phone is imported from the external world, to conductive strips 4 are set between thin film transistor (TFT), can be imported the earth by the present invention in upper polaroid 3, increased the area of the release of electrostatic 12, improve the efficiency of the release of electrostatic 12.
Second embodiment
As shown in Fig. 2 on the basis of first embodiment, the touch LCD display also includes IC chip 5, and the IC chip 5 in figure is arranged between thin film transistor (TFT) and cover plate 1, and the side of the overlapping unit where conductive strips 4 is towards IC chip 5.Namely conductive strips 4 are set towards IC chip 5, and in time by the electric capacity C2 of 3 pairs of the earth of upper polaroid, and the electric capacity of 2 pairs of the earth of mainboard is released.As can be seen that conductive strips 4 can be preferably discharged by the electrostatic 12 of IC chip 5, the impact to IC chip 5 is reduced.
3rd embodiment
As shown in Fig. 2 on the basis of first embodiment and second embodiment, the conductive strips 4 in the touch LCD display of the present embodiment are also electrically connected with colored filter 7.Thus conductive strips 4 will import the earth not only through thin film transistor (TFT) by the electrostatic 12 of IC chip 5, and the earth will be also promptly imported by the electrostatic 12 on colored filter 7, reduce 12 pairs of infringements of the part touched in transistor including colored filter 7 of electrostatic.
Fourth embodiment
As shown in Fig. 2 the present embodiment is on the basis of above three embodiment, the conductive strips 4 in the touch LCD display of the present embodiment are the silver slurry layer for being coated on overlapping unit side.Silver slurry layer is formed in the side of overlapping unit using the technique of coating, on the premise of electrostatic 12 is imported into the earth rapidly, using coating processes preferably attaching film transistor, colored filter 7 and upper polaroid 3, it is ensured that electrostatic 12 promptly imports the earth in time.
By the explanation of specific embodiment, should to the present invention for reach technological means that predetermined purpose is taken and effect be able to more deeply and it is specific understand, but appended diagram is only to provide and refers to and purposes of discussion, not for being any limitation as to the present invention.
