Abstract
The utility model discloses a high-sensitivity capacitive touch screen which comprises a panel layer, a working layer and a shielding layer, wherein the working layer is arranged below the panel layer; the shielding layer is located below the working layer; the working layer is an ITO (indium tin oxide) circuit, and is electrically connected with a touch control IC (integrated circuit); the shielding layer comprises an ITO circuit layer and a thin film layer; the thin film layer is located below the ITO circuit layer, and used for laying the ITO circuit layer; continuous bulges are arranged on the edge of the shielding layer of the high-sensitivity capacitive touch screen; the working layer is embedded into a space defined by the bulges; and the shape and the size of the space defined by the bulges are adaptable to those of the working layer. The high-sensitivity capacitive touch screen is lighter and thinner in size and higher in sensitivity.
Description
Technical field
The utility model relates to a kind of high sensitivity capacitance touch screen.
Background technology
Existing highly sensitive capacitance touch screen, thickness is thicker, and sensitivity does not also reach the desirable state of people comparatively speaking.
The utility model content
Technical problem to be solved in the utility model is on original technical foundation, provide a kind of more volume more frivolous, and a kind of like this high sensitivity capacitance touch screen that sensitivity is higher realizes that the technical scheme of above-mentioned purpose is as follows:
The high sensitivity capacitance touch screen, comprise panel layer, working lining, screen layer, working lining is below panel layer, screen layer is positioned at the below of working lining, working lining is one deck ITO circuit, working lining electrically connects touch-control IC, screen layer comprises ITO line layer, thin layer, thin layer is positioned at the below of ITO line layer, be used for laying the ITO line layer, it is characterized in that: the edge of screen layer has continuous projection, and the space that projection surrounds is embedded in working lining, and the shape size of the space that projection surrounds and working lining adapts.
Further, the lower surface of panel layer has groove, and groove is embedded in working lining, and shape, the size of groove and working lining adapt.
Further, the height of projection of screen layer is equal to or less than half of working lining height.
Further, the degree of depth of the groove of panel layer is less than or equal to half of working lining height.
The utility model volume is more frivolous, and sensitivity is higher.
Description of drawings
Fig. 1 is the utility model synoptic diagram
Figure number explanation: panel layer 1, working lining 2, screen layer 3, groove 4, ITO circuit 5, ITO line layer 6, thin layer 7, projection 8
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Among the figure, the high sensitivity capacitance touch screen, comprise by panel layer 1, working lining 2, the multi-layer compound structure that screen layer 3 is formed, and it is not shown with the touch-control IC(of working lining electric connection, those skilled in the art can be easy to understand according to existing technology), the material of panel layer 1 is selected glass or other transparent high molecular polymers usually for use, working lining 2 is below panel layer 1, screen layer 3 is below working lining 2, working lining 2 is one deck ITO circuit, the lower surface of panel layer 1 has groove 4, place ITO circuit 5 in the groove 4, the shape of groove 4, size adapts with the ITO circuit, the depth of groove 4 can arrange according to the technology that the ITO circuit adopts, because the working lining upper and lower surface is all surrounded by groove, therefore, the height of projection of screen layer is less than half of working lining height, in like manner the degree of depth of the groove of panel layer also is to be less than or equal to half of working lining height, screen layer 3 comprises ITO line layer 6, the below of ITO line layer 6 has thin layer 7, the edge of screen layer 3 upper surfaces has continuous projection 8, the shape that is equivalent to groove, place working lining in the space that projection surrounds, the shape size of the space that projection surrounds and working lining adapts, projection on the screen layer also can be to utilize its screen layer body, namely directly set out groove on the surface of screen layer, just do not need the fixing of optical cement between such arrangement works layer and the screen layer.
Working lining is embedded in the panel layer in the utility model, has directly dwindled the anode-cathode distance between finger and the working lining in fact, has reached the purpose that increases described inductance capacitance, effectively improves touch-control sensitivity.
The laying method of ITO circuit is same as the prior art.
It below only is the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
