Abstract
A kind of metal grill capacitance type touch-control panel; comprise base plate glass layer, indium tin oxide layer, metal level, protective seam, printed layers successively from top to bottom; capacitance type touch-control panel comprises base plate glass layer, wire netting compartment, protective seam, printed layers from top to bottom successively, is connected between layers by cementing agent.The utility model is by replacing indium tin oxide layer and metal level with wire netting compartment; take turns doing up-protective layer, printed layers again; this novel capacitance-type contact panel can reduce sheet resistance 20%-30%; improve touch-control reaction velocity 10%-20%; and save cost 10-15%, and middle large touch panel can be widely used in.
Description
Technical field
The utility model relates to a kind of metal grill capacitance type touch-control panel, belongs to Optical touch screen technology field.
Background technology
Capacitance type touch-control panel is the capacitance variations utilizing the electrostatical binding of asking of transparency electrode and human body to produce, from produced its coordinate of induction electro-detection.Principle of induction acts on four corners of screen induction zone with voltage and forms a stationary electric field, when finger touches screen, electric field can be made to cause electric current, measure, according to the difference of current distance four angle ratios, can calculate contact position by controller.
Its structure of conventional condenser contact panel process recipes is that base plate glass takes turns doing indium tin oxide layer and metal level, protective seam, printed layers.Cost due to tin indium oxide is higher and only rest in minority Japanese trader hand, and the conductive layer that tin indium oxide is made can not be satisfied with the demand for development of middle large size capacitive touch screen because sheet resistance is too high, so find a kind of low square resistance and the low material of cost becomes a kind of trend to replace tin indium oxide.
Utility model content
For the problems referred to above, the utility model provides a kind of metal grill capacitance type touch-control panel, its object is to: while cost-saving, can reduce the sheet resistance of conductive layer, the reaction velocity of large touch screen in raising, in the development of large-sized capacitance type touch control screen provide conveniently.
Technical solution of the present utility model:
A kind of metal grill capacitance type touch-control panel; comprise base plate glass layer, indium tin oxide layer, metal level, protective seam, printed layers successively from top to bottom; it is characterized in that: described capacitance type touch-control panel comprises base plate glass layer, wire netting compartment, protective seam, printed layers from top to bottom successively, is connected between layers by cementing agent.
Described wire netting compartment is that film is connected with base plate glass layer by screen painting mode, and described film is connected with protective seam by light blockage coating mode.
Described wire netting compartment is silver, copper metal material or oxide, and its lowest resistance value can reach 0.1 ohm-sq inch.
Described protective seam is that photoresist mainly plays the effect preventing electrostatic, and printed layers is strippable colloidal materials, mainly plays the effect of protection.
The beneficial effects of the utility model:
The utility model is by replacing indium tin oxide layer and metal level with wire netting compartment; take turns doing up-protective layer, printed layers again; this novel capacitance-type contact panel can reduce sheet resistance 20%-30%; improve touch-control reaction velocity 10%-20%; and save cost 10-15%, and middle large touch panel can be widely used in.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Wherein: 1 base plate glass layer 2 wire netting compartment 3 protective seam 4 printed layers.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
A kind of metal grill capacitance type touch-control panel as shown in Figure 1, described capacitance type touch-control panel comprises base plate glass layer 1 from top to bottom successively, wire netting compartment 2, protective seam 3, printed layers 4, connected by cementing agent between layers, described wire netting compartment 2 is connected with base plate glass layer 1 by screen painting mode for film, described film is connected with protective seam by light blockage coating mode, the material of described wire netting compartment 2 is the silver that resistivity is very little, the metal materials such as copper, the tin indium oxide resistivity used than tradition is much lower, so better electric signal can be transmitted, improve touch-control reaction sensitivity, in large-sized contact panel due to can touch-control area greatly for electric signal transmission speed require higher, so it is more obvious to be applied in advantage on middle large touch panel, described protective seam 3 is that photoresist mainly plays the effect preventing electrostatic, printed layers 4 is strippable colloidal materials, mainly play the effect of protection.
This novel capacitance-type contact panel as from the foregoing, sheet resistance is low, touch-control reaction is sensitiveer, and the cost of material is low, is applied in advantage on middle large touch panel more obvious.
The utility model is by replacing indium tin oxide layer and metal level with wire netting compartment; take turns doing up-protective layer, printed layers again; this novel capacitance-type contact panel can reduce sheet resistance 20%-30%; improve touch-control reaction velocity 10%-20%; and save cost 10-15%, and middle large touch panel can be widely used in.
To sum up, the utility model accomplishes the end in view.
