Abstract
The invention relates to a capacitive touch screen. The capacitive touch screen is connected with a main panel through a circuit, at least one part of the circuit is bridged on a panel, and a silver paste circuit is bridged on an OGS (One Glass Solution) panel, so that an FPC (Flexible Printed Circuit) space can be saved, the designing space of the whole machine can be greater expanded, the connecting technology between the FPC and the touch screen can be simplified, the number of connecting pins can be reduced, the manufacturing requirements of the FPC can be reduced, and the production efficiency and yield of the FPC can be improved.
Description
Technical field
The present invention relates to touch-screen field, be specifically related to a kind of capacitive touch screen.
Background technology
Screen is touched in electric capacity touch, and man-machine conversation is carried out in available finger touch operation, is generally used in touch-screen mobile phone, touch-screen PDA, and panel computer, in automatic navigator and other industrial control equipments.
Along with scientific and technical development, capacitive touch screen has become the operation interface that the electronic equipment such as mobile phone, notebook is new.Its circuit bridging of existing capacitance touch screen is all realized on FPC.Like this, require FPC to have very large design space, restricted greatly the structure of terminal complete machine, and the pin being connected with touch-screen is too many, greatly affected production efficiency and the yield of touch-screen connection technique.In addition, such connected mode requires also suitable height to the making of FPC, has restricted production efficiency and the yield of FPC.
Summary of the invention
For addressing the above problem, the invention provides a kind of capacitive touch screen of a part of circuit bridging on panel that have at least.
For achieving the above object, technical scheme provided by the invention is: the invention provides a kind of capacitive touch screen, have a part of circuit bridging at least on cover.
Further, above-mentioned touch-screen cover is OGS panel.
Further, the circuit of above-mentioned bridge formation on panel by silver slurry printing and ITO etching in conjunction with wiring.
Further, above-mentioned circuit can some be built bridge on FPC.
Further, on the circuit of above-mentioned bridge formation on FPC, can stick on and control IC chip.
Adopt the beneficial effect of the technical program to be: by technical scheme of the present invention, have the capacitance touch screen technology of a part of circuit bridging on panel at least, farthest save FPC space, larger expansion the design space of complete machine, simplify the be connected technique of FPC with touch-screen, reduce connecting pin quantity, reduced the making requirement of FPC, and improved the production efficiency of FPC.
