A kind of electronic equipment, the touch-screen that adopts the utility model embodiment to be provided.
Touch-screen that the utility model embodiment provides and electronic equipment, the composite membrane that will have touch sensor is arranged on the viewing area, around simultaneously in the viewing area conducting film is set, this conducting film is except the signal transmission interface part, can cover a week on every side in the viewing area, when there is undesired signal in the external world, can be by this conducting film shielding part, and the conducting film among the utility model embodiment is by the earthing of casing, thereby the electric current that will shield the undesired signal generation directly is conducting to earth point.So, can reduce the interference that touch sensor is subjected to behind employing the utility model embodiment.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the vertical view of the utility model embodiment touch-screen;
Fig. 2 is the side schematic view of the utility model embodiment touch-screen.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of touch-screen, this touch-screen comprises display device, for convenience of description, among the utility model embodiment the one side that presents picture to the user on the display device is called display surface, as shown in Figure 1, be provided with composite membrane 11 in the viewing area of described display surface 10 with touch sensor, be provided with the signal transmission interface 12 of described composite membrane among the utility model embodiment in the part of described viewing area side, the signal wire 13 of touch sensor all is connected to signal transmission interface 12, can transmit the touch signal that touch sensor receives by this signal transmission interface 12, so that handle.
In order to shield external interference signals to prevent the operate as normal of electrostatic influence to touch sensor, the utility model embodiment is equipped with conducting film 14 on every side in the viewing area except described signal transmission interface 12 parts, and the housing contacts (referring to Fig. 2) of described conducting film 14 and described display device can be with conducting film ground connection by described shell 15.
When there is undesired signal in the external world, can be by a part of undesired signal of this conducting film 14 shieldings, and the conducting film among the utility model embodiment 14 is by the earthing of casing, thus the electric current that will shield the undesired signal generation directly is conducting to earth point.So, can reduce the interference that touch sensor is subjected to behind employing the utility model embodiment.
The display device of being mentioned among the utility model embodiment can be any display device, as liquid crystal panel, Plasmia indicating panel or the like.As shown in Figure 2, when display device is liquid crystal panel, this liquid crystal panel comprises tft array substrate 17, color membrane substrates 16 and the liquid crystal 18 that instils between tft array substrate 17 and color membrane substrates 16, the lateral surface of color membrane substrates 16 is a display surface, around color membrane substrates 16 viewing areas, be provided with conducting film 14, the shell of above-mentioned described display device then is the housing 15 of liquid crystal panel, as can be seen from Figure 2 conducting film has touched the housing 15 of liquid crystal panel, and the housing 15 of liquid crystal panel generally is a ground connection, thereby can be with conducting film 14 ground connection.
