Touch device described in the embodiment of the present invention on un-flexed direction by using the transmitting of touch-control wave and touch-control wave to connect The touch control manner of receipts uses touch-control driving/line of induction touch control manner on bending direction, so that large scale song both may be implemented Face is shown, and can reduce the number of plies of touch control electrode, simplifies technique, and touch panel described in the embodiment of the present invention can be in big ruler Have both that processing procedure is simple, yield is high and advantage at low cost when very little curved-surface display.

In practical operation, touch device described in the embodiment of the present invention can preferably use infrared ray in un-flexed direction The touch control manner of transmitting and infrared receiver, can also be using other touch control manners such as surface acoustic wave touch touch-controls.The present invention is real Touch device described in example is applied by using the transmitting of touch-control wave and the received touch control manner of touch-control wave on un-flexed direction, is being protected Card may be implemented to simplify technique while touch-control.The touch control manner on un-flexed direction is illustrative only above, not It is restricted.

In practical operation, due to only being needed using using projected capacitive self-tolerant touch technology and resistance touch technology Touch-control driving/line of induction (i.e. on bending direction), therefore touch device described in the embodiment of the present invention are set on a direction Projected capacitive self-tolerant touch control manner and resistance touch control manner are preferably used on bending direction, it is above on bending direction Preferred touch control manner is illustrative only, and with no restriction.

Specifically, the touch-control wave may include infrared ray or surface acoustic wave；

The touch parameter includes self-capacitance value or impedance.

When the touch-control wave includes infrared ray, touch device described in the embodiment of the present invention uses on un-flexed direction Infrared touch control technology；

When the touch-control wave includes surface acoustic wave, touch device described in the embodiment of the present invention is adopted on un-flexed direction With surface acoustic wave touch technology；

When the touch parameter includes self-capacitance value, touch device described in the embodiment of the present invention is adopted on bending direction With projected capacitive self-tolerant touch technology；

When the touch parameter includes impedance, touch device described in the embodiment of the present invention is on bending direction using electricity Resistive touch technology.

In practical operation, when the touch-control wave includes infrared ray, the touch-control wave transmitting module may include along Multiple RF transmitters of the first side setting；

The one touch-control wave launcher scans a touch-control wave receiver.

Namely in one embodiment, the RF transmitter and the infrared receiver divide side to be arranged, And the RF transmitter and the infrared receiver are one-to-one；The processing unit 13 is red by judgement institute Whether the infrared ray that outer line receiver receives is blocked and judges on un-flexed direction with the presence or absence of touch event, and according to The infrared ray that the infrared receiver receives judges the touch-control coordinate on un-flexed direction；

The number of the RF transmitter and the number of the infrared receiver depend on the touching of curved face display panel Control the requirement of resolution ratio.

As shown in Fig. 2, the curved face display panel 20 that the first specific embodiment of touch device of the present invention is applied to Including the upper side edge 201 and lower side 202 being oppositely arranged, as shown in Figure 2, the upper side edge 201 and the second side 202 are Curved side；

(infrared ray path i.e. shown in dotted lines in Figure 2) is using single on the un-flexed direction of the curved face display panel 20 To infrared type touch-control structure, it is achieved in that in the upper end of the frame of curved face display panel 20 along upper side edge 201 from left to right Set gradually multiple RF transmitters, curved face display panel 20 frame lower end along lower side 202 from left to right according to The secondary multiple infrared receivers of setting；

The density of the setting of RF transmitter and infrared receiver depends on the touch-control resolution ratio of curved face display panel Requirement；

As shown in Fig. 2, the touch-control wave transmitting module include set gradually from left to right along upper side edge 201 it is first red Outside line transmitter 211, the second RF transmitter 212, third RF transmitter 213, the 4th RF transmitter 214, Five RF transmitters 215, the 6th RF transmitter 216, the 7th RF transmitter 217 and the 8th RF transmitter 218；

First RF transmitter 211 emits infrared light to first infrared receiver 221, by judging State whether the infrared light that the first infrared receiver 221 receives is blocked and judges whether there is touch event, and so on, The corresponding infrared receiver of i.e. one RF transmitter；

On the curved face display panel 20, it is also provided with a plurality of touch-control scanning/induction from top to bottom along bending direction Line uses projected capacitive self-tolerant in the first specific embodiment of touch device of the present invention on bending direction Touch control manner；

As shown in Fig. 2, being disposed with the first touch-control scanning/induction from top to bottom on the curved face display panel 20 Line 231, the second touch-control scanning/line of induction 232, the third touch-control scanning/line of induction 233, the 4th touch-control scanning/line of induction 234, The five touch-control scannings/line of induction 235, the 6th touch-control scanning/line of induction 236 and the 7th touch-control scanning/line of induction 237；

First specific embodiment of touch device of the present invention only needs to be arranged one layer of touch control electrode layer (touch-control electricity Only need to be equipped with a plurality of touch-control scanning/line of induction being arranged along bending direction on the layer of pole), and relatively easily realizing the non-of touch-control Using infrared touch technology (no setting is required touch control electrode) on bending direction, it can realize large scale curved-surface display, technique system Journey is simple, at low cost.

The projected capacitive that first specific embodiment of touch device of the present invention uses on curved surface bending direction The optional Add-on of the implementation of self-tolerant touch-control structure (external hanging type), In-cell (embedded) or On-cell (external), Due to only needed in structure on curved surface bending direction lay touch-control scanning/line of induction, in design difficulty significantly under Drop, finished product yield and cost have largely advantage relative to the two-way implementation of tradition.
