Compared with prior art, the touch-control display module with pressure detection provided by the utility model has the advantage that

1. what adopt due to capacitance type touch-control panel is that the principle of human induction current carries out touch point detection, and when touch control electrode and pressure detection electrode be arranged on same substrate layer and display floater near contact panel time, arrangement between components and parts and conductor wire etc. is very close, interfering very serious and causing touch point position detecting and not accurate by force value detecting between signal.This utility model will provide the gate drivers of raster data model scanning impulse to be used by selection circuit and/or pulse reformation circuit cleverly for pixel cell, selected by selection circuit and/or pulse reformation circuit, displacement, pulsewidth constriction and frequency dividing etc. provide pressure scanning pulse and touch-control scanning impulse after processing.Gated sweep pulse, can timesharing sequence or carry out with sequential between pressure scanning pulse and touch-control scanning impulse.During with sequential, gated sweep pulse, pressure scanning pulse carries out with both or the three in touch-control scanning impulse simultaneously, but the current potential switching point mutual dislocation between them is (at current potential switching point place, signal is highly prone to external disturbance and causes the signal of telecommunication unstable, signal dislocation etc.), so make the touch-control display module response speed with pressure detection fast, interference between signal reduces, and touch-control stability is better.When timesharing sequence, gated sweep pulse, pressure scanning pulse and touch-control scanning impulse carry out at times, therefore, the interference between electric signal reduces too, and the touch-control stability of the touch-control display module with pressure detection is significantly promoted.

4. adopting Wheatstone bridge to detect by force value in this utility model, its circuit structure is simple, and control accuracy is high.Most important described pressure signal processor adopt electric bridge be combined with multiplexer, different pressure sensitivity unit is selected by multiplexer, but in the Wheatstone bridge that different pressure sensitivity unit are constituted when detecting pressure force signal, resistance Ra and Rb is for sharing resistance, so design can be greatly reduced the resistance quantity in Wheatstone bridge, and difference pressure sensitivity unit is when carrying out pressure detection, owing to its fractional hardware is shared, therefore error rate each other reduces.Further, internal resistance RF0, the RF1 corresponding to described pressure sensitivity unit, RF2 RFn one_to_one corresponding is provided with RC0, RC1, RC2 RCn reference resistance each other, this reference resistance is arranged near RF0, RF1, RF2 RFn, so, the temperature that is subject between them affects consistent, and other noises being subject to also are similar to, and are so conducive to stablizing of Wheatstone bridge, reduce hardware circuit because of own temperature drift, the signal erroneous judgement that environmental factors is brought.RF0, RF1, RF2 RFn and RC0, RC1, RC2 RCn reference resistance each other, optimizes the configuration of resource while so reducing noise.The output signal end of Wheatstone bridge is connected to operational amplification circuit, and described operational amplification circuit is possible not only to be amplified output signal U 0, and it can utilize operational amplification circuit to suppress the characteristic of noise to reduce noise.Illustrate for RF0 and RC0, when the depressed power of upper substrate, RF0 resistance change is △ r, but actually RF0 is subject to producing the noise of △ s such as temperature and other interference, for reference resistance RC0, it is subject to as consistent with its neighbouring RF0 in temperature and other interference, size is also the noise of △ s, namely this noise △ s offsets with the noise of the varistor RF0 of input in the same direction after reversely at the reverse input end of operational amplification circuit, so, the interference that other noises greatly reduced bring, improve the detecting precision of pressure signal further.

5. in the present embodiment, in the non-touch-control district of touch control electrode, pressure sensitivity unit is set, pressure sensitivity unit and touch control electrode can be integrated in same plane by arranging of collets by it, the thickness of the touch-control display module with pressure detection is so greatly reduced, especially complementary between touch control electrode and pressure sensitivity unit arrange, it is possible to make to have the display effect of the touch-control display module of pressure detection more preferably.

Compared with prior art, the touch-control display module 10 with pressure detection provided by the utility model has the advantage that

1. what adopt due to capacitance type touch-control panel is that the principle of human induction current carries out touch point detection, and when touch control electrode and pressure detection electrode 161 be arranged on same substrate layer 14 and display floater 9 near contact panel 8 time, arrangement between components and parts and conductor wire etc. is very close, interfering very serious and causing touch point position detecting and not accurate by force value detecting between signal.The gate drivers 181a providing raster data model scanning impulse for pixel cell 91 is used by this utility model cleverly by selection circuit 184 and/or pulse reformation circuit 185, selected by selection circuit 184 and/or pulse reformation circuit 185, displacement, pulsewidth constriction and frequency dividing etc. provide pressure scanning pulse and touch-control scanning impulse after processing.Gated sweep pulse, can timesharing sequence or carry out with sequential between pressure scanning pulse and touch-control scanning impulse.During with sequential, gated sweep pulse, pressure scanning pulse carries out with both or the three in touch-control scanning impulse simultaneously, but the current potential switching point mutual dislocation between them is (at current potential switching point place, signal is highly prone to external disturbance and causes the signal of telecommunication unstable, signal dislocation etc.), so make touch-control display module 10 response speed with pressure detection fast, interference between signal reduces, and touch-control stability is better.When timesharing sequence, gated sweep pulse, pressure scanning pulse and touch-control scanning impulse carry out at times, therefore, the interference between electric signal reduces too, and the touch-control stability of the touch-control display module 10 with pressure detection is significantly promoted.

2. at least one screen layer is between the plurality of pixel cell 91 and multiple touch control unit 171, and/or between described at least one pressure sensitivity unit 161 and between touch control unit 171, described screen layer can be effectively reduced the mutual signal interference between contact panel 8 and display floater 9, between touch control unit and pressure unit.

3. this has the touch-control display module 10 of pressure detection while displaying, and it can not only detect touch point position, and can detect the force value of touch point.Touch sensing 17 is driven by same gate drivers 181a with pressure transducer 16, which save hardware cost, simplify circuit design, improve the integrated level of the touch-control display module 10 with pressure detection, and reduce thickness and the weight of the touch-control display module 10 with pressure detection to a certain extent.Touch sensing 17 is close with on the conductive line structure of pressure transducer 16 and display floater 9, prior art adopt different drivers respectively to pixel cell 91, touch control unit 175 and pressure sensitivity unit 161 are driven, its design space is compared little, the arrangement of components and parts is unfavorable for heat radiation closely, and this utility model then solves this problem well.

4. adopting Wheatstone bridge to detect by force value in this utility model, its circuit structure is simple, and control accuracy is high.Most important described pressure signal processor 19 adopt electric bridge 191 be combined with multiplexer 192, different pressure sensitivity unit 161 is selected by multiplexer 192, but in the Wheatstone bridge that different pressure sensitivity unit 161 are constituted when detecting pressure force signal, resistance Ra and Rb is for sharing resistance, so design can be greatly reduced the resistance quantity in Wheatstone bridge, and difference pressure sensitivity unit 161 is when carrying out pressure detection, owing to its fractional hardware is shared, therefore error rate each other reduces.Further, internal resistance RF0, the RF1 corresponding to described pressure sensitivity unit 161, RF2 RFn one_to_one corresponding is provided with RC0, RC1, RC2 RCn reference resistance each other, this reference resistance is arranged near RF0, RF1, RF2 RFn, so, the temperature that is subject between them affects consistent, and other noises being subject to also are similar to, and are so conducive to stablizing of Wheatstone bridge, reduce hardware circuit because of own temperature drift, the signal erroneous judgement that environmental factors is brought.RF0, RF1, RF2 RFn and RC0, RC1, RC2 RCn reference resistance each other, optimizes the configuration of resource while so reducing noise.The output signal end of Wheatstone bridge is connected to operational amplification circuit, and described operational amplification circuit is possible not only to be amplified output signal U 0, and it can utilize operational amplification circuit to suppress the characteristic of noise to reduce noise.Illustrate for RF0 and RC0, when upper substrate 11 depressed power, RF0 resistance change is △ r, but actually RF0 is subject to producing the noise of △ s such as temperature and other interference, for reference resistance RC0, it is subject to as consistent with its neighbouring RF0 in temperature and other interference, size is also the noise of △ s, namely this noise △ s offsets with the noise of the varistor RF0 of input in the same direction after reversely at the reverse input end of operational amplification circuit, so, the interference that other noises greatly reduced bring, improve the detecting precision of pressure signal further.All can use it practice, offset maneuver in the noise that operational amplification circuit is possible, for instance, U=A ((V+)-(V-))=A ((V_△r+V_△s)-(-V_△r+V_△s))=2AV_△rWhat △ s system was not affected by backward voltage and existed outside causes noise effect; wherein use differential amplifier or amplifier combination to be all the maneuver that this utility model can adopt, be not limited thereto, as long as the outside circuit causing noise effect of preventing is abide by the law is all this utility model protection domain.

5. in the present embodiment, in the non-touch-control district 174 of touch control electrode, pressure sensitivity unit 161 is set, pressure sensitivity unit 161 and touch control electrode can be integrated in same plane by arranging of collets 173 by it, the thickness of the touch-control display module 10 with pressure detection is so greatly reduced, especially complementary between touch control electrode and pressure sensitivity unit 161 arrange, it is possible to make to have the display effect of the touch-control display module 10 of pressure detection more preferably.

Refer to Fig. 9, this utility model the second embodiment provides a kind of touch-control display module (all non-label) with pressure detection, the described touch-control display module with pressure detection shows the difference is that only of module 10 with the touch-control with pressure detection of first embodiment: described touch-control scanning impulse is inconsistent with the timing variations of pressure scanning pulse and gated sweep pulse, touch-control scanning impulse and pressure scanning pulse in the present embodiment all carries out with sequential with gated sweep pulse, but between touch-control scanning impulse and pressure scanning pulse, timesharing sequence carries out.The pulsewidth after driving pulse process circuit of pressure scanning pulse and touch-control scanning impulse narrows, so, time slot is there is between gated sweep pulse and pressure scanning pulse and touch-control scanning impulse, for example, in Vg_1, gated sweep pulse is at t1 and t2 moment switching electric potential, in Vt_1, touch-control scanning impulse pulsewidth is less than gated sweep pulse, it is at t3 and t4 moment switching electric potential point, in Vf_1, pressure scanning pulse is less than gated sweep pulse, it is at t5 and t6 moment switching electric potential point, t1 < t3 < t4 < t2 < t5 < t6, pixel cell, the current potential switching point of the running between touch control unit and pressure sensitivity unit offsets one from another.At current potential switching point, between touch control electrode, pressure transducer and pixel cell easily mutually signal interference and cause touch point position and accurate by force value detecting, the present embodiment then by gated sweep pulse, pressure scanning pulse arranges regular hour gap with touch-control scanning impulse makes the current potential switching point dislocation of the rwo avoid signal interference each other.The pulsewidth of touch-control scanning impulse described in practical operation and described pressure scanning pulse is not wider than the pulsewidth of described gate driving pulse.
