Description
Technical field
The utility model relates to a kind of touch-screen, in particular a kind of improvement of touch screen base plate electrode structure.
Background technology
The touch-screen full name that is commonly called as should be transparent touch panel (Transparent Touch Panel), is called for short T/P.Generally place on the picture such as liquid crystal and play the transparent switch effect, touch picture and then can directly import.It has simply, makes things convenient for, saves advantages such as space as input equipment.
The touch-screen kind is a lot, resistance-type, capacitor induction type, infrared type, surface acoustic wave type or the like are arranged, advantage such as resistance-type is simple in structure because of it, and low in energy consumption, cost is low, occupied the principal market on the handheld devices such as PDA and mobile phone, wherein main is 4 wire resistance type touch-screens.
As shown in Figure 1, resistive touch screen is mainly by upper electrode 110, lower electrode 120, and 3 basic structures such as connector 130 grades are formed.Upper electrode 110: the general PET film that ITO (indium oxide) film is arranged that adopts.Lower electrode 120: can adopt PET film, glass or the plastics of ITO film, the well-regulated insulation kick 121 of printing above it.Connector 130: insert being connected between being heat fused in TTP between the electrode of upper and lower and installing.Layers of two-sided 140: on the power that sticks with glue is fixing, lower electrode and make the upper and lower part electrode keep certain intervals.ITO (indium oxide) film: nesa coating; Extremely thin, promptly transparent conduction again.
Resistive touch screen is a multi-layer compound film, by one deck glass, plastics or PET Film (PET film) as basic unit, the surface scribbles the conductive layer (ITO, indium oxide) of layer of transparent, is stamped one deck outside surface cure process, smooth scratch resistant PET Film above again.Its inside surface also scribbles one deck ITO, has the transparent isolating points of many tiny (less than mils) that they are separated insulation between two conductive layers.When finger 200 contact screens, a contact point conducting appears in two-layer ITO conductive layer, thereby realizes the touch operation function, as shown in Figure 2.
The ITO (indium oxide) that plays the conducting effect at resistive touch screen is the weakly conducting body, and characteristic is to drop to 1800 dust (dust=10 when thickness
-10Can become transparent suddenly when promptly 1/10000000000th meter in rice) following, transmittance is more than 80%.So can work as touch display screen conduction usefulness, but easy brittle failure when relatively thinner of ITO film, and be coated with to such an extent that too thickly can reduce printing opacity and form the sharpness that internal reflection reduces display screen.The touch display screen of prior art is added the thin plastic protective layer of one deck though adopt outside the ITO film, still destroyed by sharp keen object easily; And owing to often be touched, the ITO film fine cracks can occur after using certain hour, even distortion, be damaged and rupture as outer ITO wherein, just lose effect as electric conductor, the touch display screen of prior art that Here it is has been used frequent appearance of a specified duration and has been touched malfunctioning reason, as abnormal conditions such as fly line occur.
And the touch-screen of prior art plays the ITO (indium oxide) of conducting effect because design is unreasonable, the situation of ITO layer short circuit can occur making, causes touch-screen response entanglement, can't normally use.
Therefore, prior art has yet to be improved and developed.
