Conductive connection pads 310c is arranged in the first perimeter circuit district B1, and conductive connection pads 310c electrical connection touch-control sensing layer 310a, and common electrode 310b and conductive connection pads 310c are electrically insulated.Signal transmission thing 330 is disposed between array base palte 320 and the subtend substrate 310, and is arranged in the first perimeter circuit district B1.In the present embodiment, signal transmission thing 330 is made of columnar projections 332 and the electric-conductor 334 that covers on the columnar projections 332, and is disposed at and is example on the subtend substrate 310.Electric-conductor 334 is electrically connected with conductive connection pads 310c, so that in fact touch-control sensing layer 310a be electrically connected with signal transmission thing 330.The electric-conductor 334 of present embodiment can be made with conductive connection pads 310c, but in other embodiments, electric-conductor 334 also can be made with the different process step respectively with conductive connection pads 310c.

For instance, the electric-conductor 334 and the columnar projections 332 of signal transmission thing 330 can be produced on the subtend substrate 310, on the electric-conductor 334 of signal transmission thing 330 and the control circuit 340 that columnar projections 332 can be produced on array base palte 320, signal transmission thing 330 for example is to be disposed on the array base palte 320 and be positioned at control circuit 340 times, signal transmission thing 330 are disposed on subtend substrate 310 and the array base palte 320 or the combination of above-mentioned signal transmission thing 330 mentioned allocation positions simultaneously by columnar projections 332.

Other are implemented example and also can utilize any process that the signal transmission thing 330 that signal transmits thing 330 or other type is disposed between two substrates 310,320, so that signal transmission thing 330 can be electrically connected with conductive connection pads 310c.What deserves to be mentioned is that the signal transmission thing 330 that is disposed between subtend substrate 310 and the array base palte 320 is in order to touch-control sensing layer 310a institute sensed signal is transferred in the control circuit 340.Therefore, signal transmission thing 330 also can be that electric conductivity colloid or other conductive material are made, and for example is to be covered with conductive material, conductive polymeric acceptor or above-mentioned mixing on elargol, the polymeric acceptor surface to use, and is not limited to above-mentioned material.

Further specify the type of drive of driving circuit 350, please continue with reference to Fig. 3, because driving circuit 350 is electrically connected with dot structure 322 on the array base palte 320, therefore driving circuit 350 can transmit sweep signal and data-signal to dot structure 322, and the direction that wherein transmits sweep signal and data-signal is shown in the direction of arrow A 1.In addition, driving circuit 350 also can be sent to the common electrode signal on the array base palte 320 on the subtend substrate 310 common electrode 310b.The mode of transmitting the common electrode signal can be the conductive materials (not illustrating) that utilizes in the frame glue 370, be covered with conductive material on for example most polymeric acceptor surface, for example: gold goal (Au Ball), ping-pong ball, copper ball etc., conductive polymeric acceptor or other can transmit the common electrode signal for the material of conduction etc.In addition, the method for transmitting the common electrode signal also can be the conducting resinl (not illustrating) that utilizes outside the frame glue 370, for example is elargol etc., maybe can be for the other materials transmission of conduction.Also be, the direction of transmitting the common electrode signal is the direction from array base palte 320 to subtend substrate 310, but the medium that transmits the common electrode signal does not limit, for example can be on the polymeric acceptor surface and be covered with conductive material, for example: gold goal (Au Ball), ping-pong ball, copper ball etc., conductive polymeric acceptor, conducting resinl or its combination, or other can transmit the medium of common electrode signal.

On the other hand, control circuit 340 can be learnt by the path direction of arrow A 2 with the signal transitive relation of touch-control sensing layer 310a.It is example that dielectric layer 310e has contact hole 312e, touch-control sensing layer 310a is contacted with conductive connection pads 310c, but also can not have contact hole 312e.So when the user touched a certain optional position P on the subtend substrate 310, the action of touching made touch-control sensing layer 310a produce sensing signal because of capacitance variations.

In other words, have capacity effect between touch-control sensing layer 310a and the common electrode 310b, the total capacitance effect of all these touch-control structures is the summation of above-mentioned capacity effect.Therefore, when the user to have the object of ground signalling or current potential, for example: user finger or other object, during the touching touch-control structure, produce capacity effect between the touch points because of touch-control sensing layer 310a and user, and then cause the total capacitance effect change, and produce sensing signal.Then, reach conductive connection pads 310c from touch-control sensing layer 310a.Contact because conductive connection pads 310c and signal transmit the electrical of thing 330, sensing signal can be reached in the control circuit 340 of array base palte 320 by the electric-conductor 334 that signal transmits thing 330.More specifically, when the form of signal transmission thing 330 or configuration slightly adjusted, the path of arrow A 2 also can slightly adjust thereupon, but the path direction of arrow A 2 is still kept from subtend substrate 310 to array base palte 320 direction.That is to say that the direction of transfer of the sensing signal of present embodiment is opposite haply with the direction of transfer of common electrode signal.

In addition, transmit sensing signal, also can utilize other conductive materials to transmit sensing signal except utilizing above-mentioned signal transmission thing 330.In other words, signal transmission thing 330 is not limited to above-mentioned form, signal transmission thing 330 also can and be distributed on wherein a plurality of polymeric acceptors surface by colloid and be covered with conductive material, and for example: gold goal (Au Ball), ping-pong ball, copper ball etc., conductive polymeric acceptor or other can be for the materials of conduction.In addition, more specifically, when the form of signal transmission thing 330 or allocation position slightly adjusted, the path of arrow A 2 also can slightly adjust thereupon, but the path direction of arrow A 2 is still kept from subtend substrate 310 to array base palte 320 direction.What in addition, each conductive connection pads 310c can be corresponding is electrically connected with a signal transmission thing 330 or a plurality of signal transmission thing 330.

Touch control display panel 300 can utilize a plurality of separation materials (not illustrating), for example sphere gap thing (BallSpacer), photoresistance separation material (Photo Spacer) or above-mentioned combination, the gap of keeping subtend substrate 310 and array base palte 320.Wherein, the process of configuration sphere gap thing for example is that the sphere gap thing is spilt cloth in the AA of the viewing area of subtend substrate 310, and is then, again that subtend substrate 310 and 320 groups of array base paltes is upright.On other embodiment, the sphere gap thing can be spilt cloth on array base palte 320, or the sphere gap thing is spilt cloth simultaneously on array base palte 320 and subtend substrate 310.

Accept above-mentionedly, the photoresistance separation material is for example used in the also available multi-form gap of keeping two substrates 310,320 of other embodiment.Fig. 4 illustrates the diagrammatic cross-section into the touch control display panel of another embodiment of the present invention.Please refer to Fig. 4, touch control display panel 400 is roughly similar to above-mentioned touch control display panel 300, and its subtend substrate 310 also has a plurality of photoresistance separation material 410f.Photoresistance separation material 410f is arranged in viewing area AA, in order to keep the gap of subtend substrate 310 and array base palte 320.On the practice, in the processing step of subtend substrate 310, photoresistance separation material 410f can be configured on the subtend substrate 310, then that subtend substrate 310 and 320 groups of array base paltes is upright.Yet the people who is familiar with this skill can make the separation material of any form, any material, keep gap between subtend substrate 310 and the array base palte 320 with the combination of above-mentioned any separation material or with the position of separation material.
