According to above-mentioned, embodiment two layers of driving electrodes of proposition and one layer of sensing electrode, using the drive as touch-control module
Moved end and receiving terminal.In embodiment, by first electrode layer 231/331/431 (first driving electrodes A1, A2, A3, A4 ... An) and
The second electrode lay 233/333/433 (second driving electrodes B1, B2, B3, B4 ... Bm) respectively exports a discernible signal, the 3rd electrode
Layer 235/335/435 (sensing electrode C) can then receive each driving electrodes A1, A2, A3, A4 ... An and driving electrodes B1, B2,
B3, B4 ... Bm value.When touch-control occurs, signal at its touch-control can with not in contact with when signal have notable difference, control
Device recognizes touch point by having in the signal of drop again.For example, during not in contact with touch-control module, first driving electrodes A1, A2, A3,
A4 ... An, second driving electrodes B1, B2, B3, B4 ... Bm export one first signal and a secondary signal respectively, when single-point or multiple spot
When contacting touch-control module, first, second signal changes, via first, second signal of change, a logical operation list of controller
Member via analysis and computing it is convertible go out the single-point or multiple spot position coordinate, and then recognize touch point.
In one embodiment, driving electrodes A1, A2, A3, A4 ... An and driving electrodes B1, B2, B3, B4 ... Bm recognizable letter
Number be, for example, single or several pulse (pulse), frequency (freq), phase (phase), string ripple, triangular wave or modulating signals or
The signal (such as orthogonal code ...) of one mathematical combination.This exposure is not specially limited.For example, it detects mode such as A1 signals as frequency
Rate Freq-A1, B2 signal is frequency Freq-B2, and in non-touch-control, its signal intensity detected is AmpA1, AmpB2, and is worked as
When touch-control occurs, and the Strength Changes of A1 signals and B2 signals are AmpA1 ', AmpB2 ', analyze and transport via ALU
Calculation can be learnt：A1, B2 intersection point are touch point, and change out its respective coordinates value.
Furthermore first driving electrodes A1, A2, A3, A4 ... An and second driving electrodes B1, B2, B3, B4 ... Bm driving side
Formula can drive all electrodes simultaneously；Or while all first driving electrodes A1, A2, A3, A4 ... An are driven and
Second driving electrodes B1, B2, B3, B4 ... Bm timesharing drives；Or first driving electrodes A1, A2, A3, A4 ... An and second driving
The equal timesharing driving of electrode B 1, B2, B3, B4 ... Bm.This exposure is to this and is seldom restricted.If the first driving electrodes and the second driving
Electrode drives simultaneously when, then sensing electrode C can simultaneously receive corresponding signal.If the first driving electrodes and the second driving electrodes point
When drive, then sensing electrode C successively receives corresponding signal.
Compared to traditional touch-control module, its receiving terminal needs multiple receivers, the touch-control proposed of this exposure embodiment
Formula display device, its drive module only need single receiver (the sensing electrode C being electrically connected to each other) to reach signal to connect
Receive.Furthermore such as the three axial electrode frameworks that embodiment is proposed, the design of first, second driving electrodes can be such that controller obtains rapidly
The xy positions of one or more touch points are obtained, it is more simplified compared with known technology in analysis calculating and Coordinate Conversion.
In summary, although the present invention is disclosed above with preferred embodiment, so it is not limited to the present invention.This hair
Bright those of ordinary skill in the art, without departing from the spirit and scope of the present invention, when various changes can be made
With retouching.Therefore, the scope of protection of the present invention is defined by those of the claims.
