An upper base board and a lower base board of a resistive film with an x-axis and y-axis cross configuration induction voltage circuit are abutted face to face, and pins are respectively pulled out from the peripheral intermediate positions of the upper base board and the lower base board; the upper base board and the lower base board use the resistive film with the induction voltage circuit of the same structure ad a contact panel, and the single lower layer base board or the single upper layer base board is used for the switchover of voltage. In this way, the space of a driving mode can be increased, and the present invention is not constrained by the single driving mode; in addition, the present invention is provided with a plurality of groups of checking circuits, which can increase the selectivity of the checking circuits and avoid the inoperative situation because of the damage of a single circuit.
Description
Technical field
The present invention is relevant a kind of contact panel, refers to the contact panel of many detectings of a kind of tool circuit especially.
Background technology
Because science and technology progresses greatly day by day, the more and more diversification of input media of products such as drive information, communication, electronics, the contact panel of brand-new input media-hommization has an opportunity to become another necessity, contact panel (Touch Panel) is the face glass that utilizes electro-conductive glass and conductive film to constitute, and shows that with touch control manner required image is in the input media of screen by the control IC of winding displacement and circuit board.
Contact panel is with the input interface characteristic of its hommization, needs any instruction, study hardly, can directly click requiredly according to the indication of the function on the picture with finger or pointer etc., and range of application is very extensive.Main range of application comprises:
(1) portable communication, consumer electronics and information products: as PDA(Personal Digital Assistant), palmtop computer (Palm-Sized PC), electronic dictionary, hand input device, information household appliances (Information Appliance), numerical digit wideband mobile phone of new generation (containing 3G and GPRS mobile phone etc.), stock market information display (as Info Touch of E-TEN Corp);
(2) finance/commercial use: as drawing/ticket sale system, marketing system, long-range video conference, terminal set system;
(3) health care purposes: follow the trail of as hospital registration system, operating table monitoring, medical science;
(4) industrial use: as factory automation control system, long-range/central monitoring system, workstation operating system, management information system (MIS);
(5) public information purposes: airport guide system, historical relic introducing system, administrate affairs of the utilization and requisition of land information query system; And
(6) teaching/electronic game purposes: the table of game player in the recreation center, child's computer-aided instruction etc.
Contact panel market accounts for maximum ratio with industrial use at present, is followed successively by the guide to visitors purposes, sells purposes such as the point of checking out, medical treatment and electronic game.Following with products such as PDA, IA, mobile phone employing contact panel, portable communication, consumption electronic products purposes will account for the contact panel critical role.
Contact panel can be divided into according to the manner of execution difference: resistance-type, condenser type, acoustic wave, optical guided wave formula, loading varying type ... etc., but wherein the most extensively used with resistance-type again, can be divided into different structures such as four lines, five lines, six lines again according to each producer's design difference.
Wherein, the most general design of resistive technologies (Film On Glass) is used, its know-why is respectively according to X with transparent conducting glass (ITO Glass) and transparent conductive film (ITO Film), the Y-axis wiring, be provided with interlayer (dot spacer) in the top and the bottom transparency electrode, with finger, pen or other medium are exerted pressure to upper electrode, make top and the bottom electrode indirect flows, produce potential difference (PD), the way interleave place promptly forms a switch (Switch) up and down, push and produce promptly that conducting (ON)/by (OFF) effect, the coordinate position at the place that exerts pressure is further calculated in conducting (ON)/pass to controller via winding displacement again by (OFF) signal to handle.
Touch Screen can be divided into four-wire type (4Wire), five-line (5Wire) and eight line formulas (8Wire) again according to wiring mode.Four-wire type is the most general distribution pattern, and its touch-control principle is promptly formed by each 2 X-axis Y-axis of top and lower electrode.Its shortcoming impressed voltage of contact panel is for this reason done switching at upper and lower two interlayers, easily produces and disturbs; And the circuit on the space of a whole page then can cause linear bad once cut damage.
Five-line is that a bottom electrode is formed by 4 X-axis Y-axis, and upper electrode is controlled by another distribution, so the anti-resistance of upper electrode is higher, and is more not fragile.Its shortcoming contact panel for this reason only has a kind of type of drive, and detects circuit and also have only a circuit, once this circuit damage just can't be moved.
Eight line formulas are the most general distribution pattern, and its touch-control principle is promptly formed by each 4 X-axis Y-axis of top and lower electrode.Its shortcoming impressed voltage of contact panel is for this reason done switching at upper and lower two interlayers, easily produces and disturbs; And the circuit on the space of a whole page then can cause linear bad once cut damage.
Summary of the invention
Fundamental purpose of the present invention is to solve above-mentioned traditional defective, avoid defective to exist, the present invention utilizes the resistive film of the induced voltage circuit of two-layer use same structure up and down as contact panel, can increase the space of type of drive, be not subjected to the constraint of single drive mode, have many group detecting circuits in addition, can increase the selectivity of detecting circuit, can avoid situation about can't use because of the uniline corrupted; Can strengthen the using method of four-wire type and eight line formula contact panels as the switching of voltage with single lower floor or top substrate layer.
In this way, in order to achieve the above object, the present invention proposes a kind of contact panel, mainly be to have the upper substrate of resistive film of X-axis and Y-axis cross-over configuration induced voltage circuit and infrabasal plate with towards applying, and the contact position that makes this two resistive film become the Quadratic Finite Element coordinate figure obtain to detect in the contact panel of output, it is characterized by and pull out pin A, B, C, D, E, F, G, H in the centre position on upper substrate and infrabasal plate four limits respectively; When detecting the X-axis coordinate time, at the right and left pin E, the G of infrabasal plate (or upper substrate A, C), add 5V and 0V voltage, use as detecting by upper substrate (infrabasal plate) this moment, the signal of four detecting circuits of acquisition resistive film, this signal that is captured is the X-axis signal;
Then add 5V and 0V voltage at the both sides up and down of infrabasal plate (upper substrate) pin F, H (or B, D), as detecting usefulness, capture the signals of four detecting circuits of resistive film by above-mentioned upper substrate this moment, and this signal that is captured is the Y-axis signal.
