Refer to Fig. 2 and Fig. 3, Figure 2 shows that the schematic diagram of the first embodiment according to touch control display apparatus of the present invention; Figure 3 shows that the diagrammatic cross-section along AA line in Fig. 2.The invention provides a kind of touch control display apparatus 100; touch control display apparatus 100 comprises contact panel 101, display module 102 and at least one pressure-sensitive sensing unit 103; contact panel 101 has sensing area 104 and is positioned at the surrounding zone 105 outside this sensing area 104; in addition; contact panel 101 also comprise the cover plate being arranged at its top; to be protected the surface of contact panel 101, cover plate such as can use transparent glass substrate or film etc.Display module 102 comprises display panel 106 and framework 107, and framework 107 is in order to accommodate display panel 106.Wherein showing module 102 is such as liquid crystal display module.In addition, each pressure-sensitive sensing unit 103 comprises the first electrode 108, second electrode 109 and elastic insulator 110.Wherein, the first electrode 108 is arranged at the surrounding zone 104 of contact panel 101, is also the wiring area of contact panel 101; Second electrode 109 is arranged in framework 107; Elastic insulator 110 is arranged between contact panel 101 and display module 102, and correspondence is between the first electrode 108 and the second electrode 109.Wherein, according to the variable quantity of the capacitance between the first electrode 108 and the second electrode 109, touch control display apparatus 100 determines that user inputs to the pressing force F of contact panel 101.
Wherein, be with the first electrode 108 for conductive metal material is formed as example in present embodiment, but not as limit, such as the first electrode also can adopt ITO (Indium Tin Oxide, tin indium oxide) patterning to be formed.In addition, with present embodiment, also include wiring lead (not in shown in figure) in the surrounding zone 105 of contact panel 101, wiring lead is used for the first electrode 108 to be electrically connected with the connection gasket 112 of the perimeter circuit layer of contact panel.Such as wiring lead one end and each the first electrode 108 are electrically connected, the other end comes together in the side of surrounding zone, connection gasket 112 place 105, the signal of the variable quantity of the capacitance between the first electrode 108 and the second electrode 109 is imported circuit substrate (IC) carry out computing.Wherein wiring lead is such as formed by printings such as Ag (silver).Moreover, the first electrode 108 also can be made simultaneously to be formed with wiring lead, and formed by printings such as Ag.
And, for touch control display apparatus 100, there is multiple pressure-sensitive sensing device 103 to be described in present embodiment, all first electrodes 108 of all pressure-sensitive sensing units 103 peripherally district 105 and around sensing area 104 in discrete ring shooting each other disconnectedly, that is, in present embodiment, all first electrode 108 right and wrong of all pressure-sensitive sensing units 103 are continuously arranged.That correspondence, a kind of embodiment: the second electrode 109 can be arranged to continuous print one-piece construction as required, thus corresponding with the first electrode 108, all pressure-sensitive sensing units 103 like this can have the second electrode 109.In another embodiment, the second electrode 109 also can be set to discrete structure, and each second electrode 109 is with each, and the first electrode 108 is corresponding arranges.In addition, its sensing area 104 of contact panel 101 has the transparent electrode pattern of sensing, first electrode 108 also can be formed with the transparent electrode pattern of the sensing area 104 of contact panel 101 simultaneously, also can be formed at the surrounding zone 105 of contact panel 101 in another step of follow-up territory.In addition, the second electrode 109 such as can print conductive paste in framework 107 or electrically conductive ink is formed, and concrete, the second electrode 109 such as can use silver paste.
In addition, preferably, elastic insulator 110 such as uses residual strain few and the material that response rate (reply speed) is high.Polysilicone, Polyurethane system resin such as can be used as this kind of material.Above-mentioned be elastic insulator 110 such as fluid sealant, fluid sealant can utilize the viscosity of himself to be combined with the first electrode 108 and the second electrode 109.If elastic insulator 110 itself is inviscid, also in the first electrode 108 and between the second electrode 109 and elastic insulator 110, following layer can be set, to bond the first electrode 108 and elastic insulator 110 and to bond the second electrode 109 and elastic insulator.
Wherein elastic insulator 110 also can be frame-shaped elastic insulator, that is arranges ringwise around the sensing area 104 of contact panel 101, that is all pressure-sensitive sensing units 103 share an elastic insulator.So, by the setting of elastic insulator 110, can prevent the dust etc. from outside from invading contact panel 101 and framework 107 or showing between module 102, be specifically in the space 113 between contact panel 101 and display panel 106.The elastic insulator 110 of frame shape so can be made to have the sealing function of the intrusion prevented from external dust, therefore can not impact display characteristic because invading from the dust of outside.Certainly, the setting of elastic insulator 110 is not also limited with above-mentioned, such as elastic insulator 110 also can the opposite position of only corresponding first electrode 108 and the second electrode 109 be arranged, that is, if the first electrode 108 and the second electrode 109 at least one of them is discrete structure, that elastic insulator 110 also can be set to discrete structure.
Certainly, apart from the above, elastic insulator 110 also can adopt the flexible member of the insulation such as such as spring, pad or silica gel, with the effect provided support.In addition, it is worth mentioning that, in the present embodiment, because fluid sealant is isolation material, it provides a supporting role, so can not affect the capacitance coupling effect between the first electrode 108 and the second electrode 109 under the configuration of fluid sealant.In other words, user presses contact panel 101 can make fluid sealant be changed spacing between the first electrode 108 and the second electrode 109 by compressing, and then thus the capacitance between the first electrode 108 and the second electrode 109 is also changed, wherein namely the variable quantity of capacitance can be used as touch sense signals to reach touch-control sensing function.
Refer to Fig. 4 and composition graphs 3, Figure 4 shows that the touch control display apparatus shown in Fig. 3 pressed by user after schematic diagram.Utilize Fig. 3 and Fig. 4 that the operating principle of the pressure-sensitive sensing unit in present embodiment is described.In present embodiment, user applies pressing force F on contact panel 101, then the mode that the elastic insulator 110 forming pressure-sensitive sensing unit 103 reduces with its thickness strains, as shown in Figure 3, before user does not press contact panel, the spacing between the first electrode 108 and the second electrode 109 is d1; As shown in Figure 4, user applies pressing force F after contact panel 101, and contact panel 101 will tilt a little and center of gravity be offset, and the spacing between the first electrode 108 and the second electrode 109 is changed, and become d2, thus d2 is less than d1.And generally speaking, the size of electric capacity (C) becomes positive inverse ratio with the distance (d) of the two conductor objects forming electric capacity, and proportional with the overlapping area (A) of two conductor objects, that is meets following formula: C=ε A/d, wherein ε is specific inductive capacity.Thus, when the overlapping area between the first electrode 108 and the second electrode 109 is fixed, the variable quantity of the capacitance between the first electrode 108 and the second electrode 109 is by the change of the spacing between reflection first electrode 108 and the second electrode 109.Such as, user applies pressing force F after contact panel 101, and the capacitance between the first electrode 108 and the second electrode 109 can reduce.So, utilize the capacitance variation between the first electrode 108 caused by the displacement of elastic insulator 110 and the second electrode 109 and realize pressure-sensitive function.And in response to the corresponding change of capacitance, by the difference of detecting capacitance, the pressing force putting on contact panel 101 can be pushed back.Because the pressing force F that generally speaking, the variable quantity of capacitance and user are applied to contact panel has roughly proportional linear characteristic.So, can judge according to the variable quantity of capacitance the dynamics scope that pressing force F is roughly positioned at, thus pressing force is defined or judges.
In addition, more larger close to the pressing strength suffered by press points position, therefore more make capacitance obtain variable quantity close to will contract shorter of the spacing of press points position first electrode 108 and the second electrode 109 and increase.Thus, the size distribution of the variable quantity of capacitance can as the reference frame of touch position.In addition, in order to make the variable quantity of capacitance exist, the spacing between the first electrode and the second electrode only can be greater than 0.That is, the first electrode 108 in present embodiment can not contact the second electrode 109 and produce coupling effect with the second electrode 109.
In addition, in present embodiment, from the signal of the first electrode 108 gained by inputed to by connection gasket 112 be arranged at not shown circuit substrate computing circuit in, thus the variable quantity of the capacitance between the first electrode 108 and the second electrode 109 can be detected.And, according to the variable quantity of the capacitance between the first electrode 108 and the second electrode 109, also can judge that carrying out input by the pressing to contact panel 101 determines operation.
In present embodiment, touch control display apparatus 100 also comprises identifying unit, judges this pressing force in order to the variable quantity of the capacitance detected by pressure-sensitive sensing unit 103.Above-mentioned identifying unit comprises above-mentioned computing circuit, and can be used as a part for the control part of touch control display apparatus 100 and form.The variable quantity of the capacitance of identifying unit detected by each pressure-sensitive sensing unit 103 be configured on contact panel 101, and judge above-mentioned pressing force.In addition, owing to having multiple pressure-sensitive sensing unit 103 in present embodiment, identifying unit also according to the accumulated value of the variable quantity of the capacitance of each pressure-sensitive sensing unit 103, can judge above-mentioned pressing force.By this, the high-precision pressing force do not relied on the pressing position of contact panel 101 can be carried out to detect.This situation, identifying unit such as can judge pressing force according to the accumulated value of the variable quantity of above-mentioned capacitance, also can judge pressing force according to by above-mentioned accumulated value divided by the mean value of the number gained of pressure-sensitive sensing unit 103.
But in another embodiment, for avoiding the electric capacity between each pressure-sensitive sensing unit interfering with each other, also can when carrying out touch-control sensing, the first electrode 108 of corresponding each corner or position such as can sense seriatim.Especially, when one of them first electrode 108 senses, remaining can be connected to earthing potential or set potential.
Wherein, concrete, the finger contact contact panel of such as user, the sensing circuit of the sensing area of contact panel carries out the detection (this point is prior art, repeats no more for this reason) of contact panel place plane (such as XY axle composition plane) coordinate.And, the finger contact contact panel of user, thus by the pressing force that pressure-sensitive sensing unit detection court applies with the direction (such as z-axis direction) of contact panel place plane orthogonal, and judge that input determines.By this, can not only just be judged to determine by finger contact contact panel, thus can reduce erroneous input.And then can make finger under the state of contact contact panel and move on contact panel, thus operability is better.And can to contact and decision is distinguished single according to the change procedure of the first electrode 108 of pressure-sensitive sensing unit 103 and the capacitance between the second electrode 109, thus can judge to determine.Moreover the decision method of decision is not limited to this.Such as, also can the action of finger on contact panel static after, with it for benchmark, if the change of capacitance changes in the mode increased, be then judged to determine.
