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 each touch-control sensing electrode unit of touch-control circuit 1202 is flowed out by touch-control public electrode 1220, the touching signals amount that each touch-control sensing electrode unit of touching signals circuit for detecting detecting touch-control sensing electrode 1210 in touch-control circuit 1202 flows out, when not having External Force Acting, the distance between touch-control sensing electrode 1220 each touch-control sensing electrode unit and touch-control public electrode 1210 is constant, each touch-control sensing electrode unit flows out touch-control sensing electrode 1220 the touching signals amount of a background, when non-conductive touch control object 1203 presses touch-control common electrode substrate 1201, the touch-control common electrode substrate 1201 neighbouring generation of point of force application outside deformation, change the distance between near contacts touch-control common electrode substrate 1201 and display upper substrate 1241, thus the distance changed between near contacts touch-control public electrode 1220 and touch-control sensing electrode unit 1210, coupling capacitance between near contacts touch-control sensing electrode unit and touch-control public electrode 1220 becomes large, the touching signals flowing to touch-control public electrode 1220 from touch-control sensing electrode unit will strain greatly mutually, touch-control circuit 1202 is by the change of touching signals on each touch-control sensing electrode unit of detecting, judge by contact.
Because contact panel 1200 is near in the touch-control common electrode substrate 1201 of operator, set is planar touch-control public electrode 1220, planar touch-control public electrode 1220 pairs of external signals produce shielding, contact panel 1200 is only to the action-reaction of power, the change of outside electrical environment, be no matter the change of electric conductor or dielectric body, all can not affect the work of contact panel 1200.Water droplet is had on the surface at contact panel 1200, under being even immersed in the environment in water, the such dielectric of water also can not make contact panel 1200 produce misoperation or leak action, as long as touch control object 1203 presses contact panel 1200 surface, contact panel 1200 just can normally work, and contact panel 1200 is in complete waterproof state.
Because contact panel 1200 can be responded to power, when adopting tiny nib to act on contact panel 1200, the deformation that nib presses the non-touch-control place of touch-control common electrode substrate 1201 deformation ratio of place wants large, maximum in the change of touch position touching signals or touching signals, touch-control circuit 1202 detects this maximal value thus determines the position of touch point, and touch control object 1203 contact area reduces the resolution that can improve touch-control greatly.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
