Description
Technical field
The present invention relates to single-layer double-side metal electrode array capacitive touch screen.
Background technology
Touch-screen, according to the difference of principle of work and transmission medium, can be divided into resistance-type, condenser type, ultrasonic type, induction and infrared type.Wherein capacitance touch screen is high because of accuracy, easily realizes multi-point touch and is widely used.
Capacitance touch screen comprises display screen and thin-film conductor layers, and thin-film conductor layers exists the problem of sensitivity, therefore in prior art, thin-film conductor layers be arranged on display screen before, so just can reach the function of touch-control.But, what thin-film conductor layers was arranged on to display screen above will inevitably bring following shortcoming: 1,, because thin-film conductor layers is generally to have two transparent bases of transverse electrode and longitudinal electrode to be sticked to form by etching respectively, two transparent bases are located at display screen front and can shine into light loss; 2, there is moir Lou Lou patterns phenomenon; 3, two transparent bases fit together by optical cement, have optical skew, affect visual effect; 4, when user closely watches display screen, see the grid in thin-film conductor layers, affect visual effect; 5, there is the circuit of contact conductor due to the surrounding of transparent base, need to be covered with frame.
Summary of the invention
The object of the present invention is to provide a kind of single-layer double-side metal electrode array capacitive touch screen that can improve transmitance, reduce light loss.
For achieving the above object, the present invention is by the following technical solutions:
A kind of rear-mounted dual-layer, single-sided metal electrode array capacitive touch screen, it comprises display screen, and the back of described display screen is pasted with conducting film, and described conducting film comprises transparent base, the front of transparent base is provided with lateral metal electrode configuration array, and the back side is provided with longitudinal metal electrod-array; Described lateral metal electrode configuration array be parallel to each other by many and linearly the transverse metal bus of type form, described longitudinal metal electrod-array be parallel to each other by many and linearly the longitudinal metal bus of type form; Described transverse metal bus and longitudinal metal bus are all by etch-forming or printing moulding; The lead end of the lead end of described transverse metal bus and longitudinal metal bus is all parallel-connected to signal processor by grouping.
Described metal material is copper, aluminium, gold or silver-colored.Because copper, aluminium, gold, silver electric conductivity are better, the sensitivity that can greatly improve touch-screen.
The live width of described transverse metal bus and longitudinal metal bus is 0. 03-15mm, and thickness is 2-10 μ m; The spacing of adjacent two transverse metal buss is 0. 3-10mm, and the spacing of adjacent two longitudinal metal buss is 0. 3-10mm.Such structure, can improve the resolution of touch-screen.
The thickness of described display screen is 3-8mm.
Described transparent base is by PET or TAC forming materials.
The thickness of described transparent base is 20-200 μ m.
Described display screen is bendable display screen.
Transverse metal bus of the present invention and longitudinal metal bus adopt the metal material moulding of high conductivity, its surface resistance is less than 0.15-3 Ω, the sensitivity of touch-screen is high, when user's finger touch display screen, the lateral metal electrode configuration array of conducting film and longitudinal metal electrod-array can sense across display screen the electric field of human finger, thereby make to form a coupling capacitance between finger and the lateral metal electrode configuration array of conducting film and longitudinal metal electrod-array, because the electric capacity of finger present position changes, in lateral metal electrode configuration array and longitudinal metal electrod-array, there will be the induction current that flows to contact, thereby calculate faradic power and accurately calculate the position of contact by signal processor.
The present invention has the following advantages compared to existing technology:
1, the transverse metal bus on transparent base and longitudinal metal bus are all by etching or printing moulding, therefore transverse metal bus and the rule of longitudinally conducting electricity all can be carried out streamline etching or printing, improve production efficiency, and conducting film size is unrestricted, can do very greatly, therefore the size of touch-screen just can maximize, and touch-screen size minimum of the present invention can be accomplished 3 cun, maximum can be accomplished 130 cun, is widely used;
2, conducting film is arranged on to the back of display screen, can improves transmittance, reduce light loss, do not exist user to see the grid on moir Lou Lou patterns phenomenon and conducting film, greatly improved visual effect.
3, without with frame, the circuit of contact conductor being covered.
4, display screen adopts bendable display screen, because conducting film is attached to display screen back, thereby can realize the touch controllable function of bendable display screen.
