Description
Technical field
The present invention relates to a kind of touch panel structure providedly, relate in particular to the two-sided touch-control panel structure of a kind of combined resistance and capacitance touching control panel.
Background technology
The application of touch panel in recent years can be said so more and more widely, consumption electronic products are as portable type electronic products such as mobile phone, notebook, PDA(Personal Digital Assistant), Global Positioning System (GPS) (GPS), super mini-computer (UMPC), MP3 players, the numerous and confused touch panel technology that adopts, make the more friendly man-computer interface of product trend, using many known technologies at present has resistance-type and capacitive touch control techniques.
Existing electric resistance touch-control panel structure mainly is made up of two-layer ITO conductive layer up and down, general top conductive layer is an ITO film (ITO Film), and the bottom is an ito glass (ITO Glass), and stamp silver electrode so that voltage to be provided at the edge, and the centre separates with a separation material (Dot spacer), when finger or pointer when pushing ITO film (ITO Film), film can cave in and contact with the ito glass (ITO Glass) of lower floor and produce change in voltage, and then detects the position that object is exerted pressure.Electric resistance touch-control panel is applicable to than the electronic product of small size and the input of degree of precision, and the variation but general ITO film (ITO Film) meets with stresses for a long time has the problem of scratch to exist easily.
And the capacitance type touch-control panel technology can be divided into two kinds of surface capacitance type (surface capacitive) and projected capacitives (projective capacitive).Wherein the structure of surface capacitance type is to utilize glass substrate or PET to go up to arrange transparent electrode, to set up uniform electric field; Projecting type capacitor then is to see through ITO to handle, and forms that two-layer (X, ITO array Y) when finger or conductor touch panel, can produce a capacitance variations in moment, detect electric current constantly via control circuit and change, and determine to point or the touch position of conductor.Capacitance type touch-control panel can be imported with finger, so have the convenience of operation, in addition, skin in structure is a sclerosis protective seam, have outside scratch resistance, the durable advantage, the technology of surface capacitance type contact panel is only made electrode on monolithic glass or PET, need not add ITO film (ITO Film) or other material, therefore transmittance is high, all is confined to 6 but shortcoming is the conventional surface capacitance type touch-control panel " above medium-and-large-sized size product; And the projecting type capacitor contact panel has the technology of multi-point touch, means that this kind device possesses the usefulness of control tasks, thereby can be used in the control operation of high-order.But capacitance type touch-control panel produces noise effect easily, and produces misoperation in the process that detects electric current because static is arranged contact point.
Therefore demand a kind ofly touch panel structure providedly having this two kinds of advantages urgently.
