Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
The capacitive touch screen of the utility model embodiment; by the liquid crystal 103 between array base palte 101, color membrane substrates 102 and array base palte 101 and color membrane substrates 102, formed as shown in Figure 1; at the back side of color membrane substrates 102, be to be formed with electrostatic protection touch layer 104 on the another side of the black matrix layer of making of color membrane substrates; described electrostatic protection touch layer 104, for realizing the effect of electrostatic protection and touch sensible, is made by transparent metal oxide material.
Electrostatic protection touch layer 104 forms by touching array pattern and electrostatic protection discharge pattern; between electrostatic protection discharge pattern and described touch array pattern, mutually insulated is not connected mutually; the gap of the shape of electrostatic protection discharge pattern and described touch array pattern is complementary; touch array pattern and be used for realizing touch sensing function, touch array pattern and the shape electrostatic protection discharge pattern complementary with it and jointly realize electrostatic protection function.
In the present embodiment; together with electrostatic protection layer has been produced on touch sensitive layer; not only reduce the thickness of touch-screen and saved material; also eliminated the electric capacity producing between electrostatic protection layer and touch sensitive layer in prior art; thereby improved the sensitivity of touch-screen; electrostatic protection touch layer can be made by a step masking process, thereby has reduced the fabrication processing of touch-screen, has improved the production efficiency of equipment.
Concrete; the structure of electrostatic protection touch layer as shown in Figure 2; electrostatic protection touch layer is divided into electrostatic protection Petting Area 201 and binding district 202; by touching array pattern and electrostatic protection discharge pattern 203, form, touch mutually insulated between array pattern and described electrostatic protection discharge pattern 203 and be not mutually connected.The multiple row touch unit 204 that touch array pattern is arranged side by side by interval forms, and multiple row touch unit 204 is mutually insulated each other, and the gap between the shape of electrostatic protection discharge pattern 203 and multiple row touch unit 204 is complementary.
Wherein, having drawn four groups and touched array patterns and electrostatic protection discharge pattern of signal only in Fig. 2, the columns and the length that touch array pattern can arrange according to the size of touch-screen.
Touch unit comprises that charging pattern 205 and a plurality of signal receive pattern 206, charging pattern 205 is comb pattern, it is " recessed " font pattern that signal receives pattern 206, the projection 207 of charging pattern 205 is inserted the groove 208 that signal receives pattern, the pattern that charges at interval of a projection 207, insert a described signal and receive pattern 206, described charging pattern 205 and described signal receive between pattern 206 mutually insulated and do not interconnect.Charging pattern 205 and each signal receive pattern 206 and are respectively arranged with charging pattern and are connected cabling 209 and receive pattern with signal and is connected cabling 210, and the charging pattern of charging pattern and signal reception pattern is connected cabling 209 and is connected cabling 210 with signal reception pattern and extends to and bind district 202.
