Contact panel 1200 is taking the demonstration upper substrate 1241 of display panel 1240 as touch-control sensing electrode base board, at the lower surface that shows upper substrate 1241, touch-control sensing electrode 1210 is set, touch-control sensing electrode 1210 is close to the lower surface that shows upper substrate 1241, the lower surface of described demonstration upper substrate 1241 refers to and shows the upper substrate surface of touch-control common electrode substrate 1201 dorsad, touch-control sensing electrode 1210 is made up of some touch-control sensing electrode units of array arrangement, each touch-control sensing electrode unit has independent extraction electrode line, the extraction electrode line of each touch-control sensing electrode unit connects touch-control circuit 1202, show that upper substrate 1241 upper surfaces are pasted with the upper polaroid 1243 of display panel 1240, show that infrabasal plate 1242 lower surfaces are pasted with the lower polaroid 1244 of display panel 1240, touch-control common electrode substrate 1201 and showing has transparent colloid sept 1230 that can pressurized deformation between upper substrate 1241.
The touch-control sensing electrode 1210 of capacitance type touch-control panel 1200 is emitting electrodes, touch-control circuit 1202 transmits touch-control pumping signal to touch-control sensing electrode 1210, touching signals on the each touch-control sensing electrode unit of touch-control circuit 1202 flows out by touch-control public electrode 1220, the touching signals amount that the touching signals circuit for detecting detecting touch-control sensing electrode 1210 each touch-control sensing electrode units in touch-control circuit 1202 flow out, in the time there is no External Force Acting, the distance between the each touch-control sensing electrode unit of touch-control sensing electrode 1220 and touch-control public electrode 1210 is constant, flows out the touching signals amount of a background on touch-control sensing electrode 1220 on each touch-control sensing electrode unit, in the time that non-conductive touch control object 1203 presses touch-control common electrode substrate 1201, touch-control common electrode substrate 1201 produces deformation near point of force application outside, change near the touch-control common electrode substrate 1201 in contact and shown the distance between upper substrate 1241, thereby change the distance between near the touch-control public electrode 1220 in contact and touch-control sensing electrode unit 1210, it is large that near coupling capacitance contact between touch-control sensing electrode unit and touch-control public electrode 1220 becomes, the touching signals that flows to touch-control public electrode 1220 from touch-control sensing electrode unit is will phase strain large, touch-control circuit 1202 is by the variation of touching signals on the each touch-control sensing electrode unit of detecting, judge by contact.
Because contact panel 1200 is in the most close operator's touch-control common electrode substrate 1201, set is planar touch-control public electrode 1220, planar touch-control public electrode 1220 produces shielding to external signal, 1200 of the contact panels action-reaction to power, the variation of outside electrical environment, no matter be electric conductor or the variation of dielectric body, can not affect the work of contact panel 1200.On contact panel 1200 surfaces, there is water droplet, even be immersed under the environment in water, the such dielectric of water can not make contact panel 1200 produce misoperation yet or leak action, as long as touch control object 1203 presses contact panel 1200 surfaces, contact panel 1200 just can normally be worked, and contact panel 1200 is in complete waterproof state.
Because contact panel 1200 can be responded to power, in the time adopting tiny nib to act on contact panel 1200, nib presses place's touch-control common electrode substrate 1201 deformation ratios, and the deformation at touch-control place will be not greatly, in the variation maximum of position of touch place touching signals or touching signals, thereby touch-control circuit 1202 detects the position of the definite touch point of this maximal value, and touch control object 1203 contact areas reduce to improve greatly the resolution of touch-control.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
