Embodiment
Fig. 1 is the diagrammatic cross-section of contact panel according to an embodiment of the invention.Please with reference to Fig. 1, contact panel 100 comprises touch-controlling interface layer 110, touch control layer 120 and layer of compensation 140.Touch-control contact bed 110 has first surface 112, and first surface 112 has the first radian R1.In the present embodiment, the material of touch-controlling interface layer 110 for example is a glass, such as glass cover (cover glass).The first radian R1 makes first surface 112 be inner concave arc surface.In the present embodiment, the first radian R1 of first surface 112 makes to have the first thickness difference Td between maximum ga(u)ge T1 and the minimum thickness T2 of touch-controlling interface layer 110.In the present embodiment, the first thickness difference Td for example is to 1mm between 0.1 millimeter (mm).
Layer of compensation 140 is disposed between touch-controlling interface layer 110 and the touch control layer 120, has the second surface 142 in the face of touch control layer 120, and wherein second surface 142 has the second radian R2 in fact.In the present embodiment, the dielectric coefficient of the material of layer of compensation 140 for example is between 1 to 10.The material of layer of compensation 140 for example is organic material or silicon oxynitride (SiOxNx).The formation method of layer of compensation 140 for example is to use the Exposure mode of shadow tone light shield (half-tone reticle) to make.In the present embodiment, the first radian R1 for example is identical in fact with the second radian R2, and in other words, first surface 112 has consistent profile (profle) in fact with second surface 142.Therefore, the touch-controlling interface layer 110 of the below, arbitrary place of the first surface 112 of touch-controlling interface layer 110 for example is identical in fact with the thickness sum total of layer of compensation 140.In the present embodiment, first surface 112 for example is an inner concave arc surface with second surface 142.Special one what carry is that the second radian R2 of layer of compensation 140 is actually the capacitance difference that the first radian R1 because of touch-control contact bed 110 is caused and compensates.Therefore, according to conditions such as the dielectric coefficient of the dielectric coefficient of touch-control contact bed 110, the first radian R1, layer of compensation 140 or compensation demands, come the second radian R2 of design compensation layer 140.Therefore, the second radian R2 of layer of compensation 140 can be identical, close or different with the first radian R1 of touch-controlling interface layer 110.
In the present embodiment, contact panel 100 for example more comprises substrate 150, and substrate 150 is disposed between touch-controlling interface layer 110 and the layer of compensation 140.In the present embodiment, substrate 150 for example is a glass substrate.Moreover contact panel 100 for example is more to comprise adhesion layer 160, is disposed between touch-controlling interface layer 110 and the substrate 150.In other words, in the present embodiment, layer of compensation 140 for example is to be made in earlier on the substrate 150 with touch control layer 120, and metacoxal plate 150 attaches by adhesion layer 160 and touch-control contact bed 110, to constitute contact panel 100.In the present embodiment, the material of adhesion layer 160 for example be optic-solidified adhesive (SVR), transparent optical adhesive tape (Optical Clear Adhesive, OCA) or other bonding material.
In the present embodiment, be by the layer of compensation 140 and touch control layer 120 that will be made on the substrate 150, constitute contact panel 100 with 110 attachings of touch-control contact bed and be example, but the invention is not restricted to this.For instance, in one embodiment, shown in the contact panel 100a of Fig. 2, layer of compensation 140 also can directly be made on another surface 114 of touch-controlling interface layer 110 with touch control layer 120, and this surface 114 and first surface 112 are for being oppositely arranged.Therefore, can omit the configuration of substrate 150 and adhesion layer 160.
Though be that the first radian R1 with touch-controlling interface layer 110 is all example in fact mutually with the second radian R2 of layer of compensation 140, the invention is not restricted to this in the above embodiments.In other words, the first radian R1 of touch-control contact bed 110 also can be different with the second radian R2 of layer of compensation 140.For instance, in one embodiment, shown in the contact panel 100b of Fig. 3 and Fig. 4,100c, layer of compensation 140 for example is to have stair-stepped configuration, so the second surface 142 of layer of compensation 140 for example is a step-like surface.In this embodiment, the second radian R2 of the second surface 142 of layer of compensation 140 for example is similar but inequality with the first radian R1 of touch-controlling interface layer 110, that is to say, the first radian R1 and the second radian R2 are all inner concave arc surface in fact.In this embodiment, layer of compensation 140 can form by the mode of patterning.Touch control layer 120 for example is to be disposed on the second surface 142 of layer of compensation 140.In addition; In another embodiment; Can select for use dielectric coefficient greater than the material of Fig. 3 and layer of compensation 140 shown in Figure 4 layer 140 (selecting the material of the big dielectric coefficient of tool for use) by way of compensation, the difference in thickness with further reduction layer of compensation 140 that is to say; Can dwindle the minimum thickness of layer of compensation 140 and the thickness difference between the maximum ga(u)ge, should big dielectric coefficient for example be greater than 6 wherein.Thus, because layer of compensation 140 has less difference in thickness and more smooth surface, therefore help on layer of compensation 140, making first conductive layer 122 of touch control layer 120.
In one embodiment, shown in the contact panel 100d of Fig. 5 and Fig. 6,100e, contact panel 100d, 100e more comprise flatness layer 170, are disposed between layer of compensation 140 and the touch control layer 120.In the present embodiment, the dielectric coefficient of flatness layer 170 for example is the dielectric coefficient less than layer of compensation 140.In the present embodiment, touch control layer 120 for example is to be disposed on the flatness layer 170.In the present embodiment; Because touch control layer 120 can be made on the flatness layer 170 with flat surfaces; Compared to directly touch control layer 120 being made on the layer of compensation 140 with radian or uneven second surface 142 such as stepped, can significantly reduce the difficulty of making touch control layer 120.Thus, can simplify the making of contact panel 100d, 100e.Special one carry be, in one embodiment, by the dielectric coefficient of suitably selecting flatness layer 170, can be so that flatness layer 170 can exert an influence to the capacitance that touch control layer 120 is sensed hardly.In other words, can ignore the contribution of flatness layer 170 for capacitance.In another embodiment, also can select can with the dielectric coefficient of the flatness layer 170 of the dielectric coefficient of layer of compensation 140 collocation, make flatness layer 170 compensate the capacitance difference that the first radian R1 because of touch-controlling interface layer 110 is caused with layer of compensation 140.In other words, in this embodiment, by layer of compensation 140 and flatness layer 170 are set, because of the sensed intensities error that the non-horizontal surface 112 of touch-control contact bed 110 is caused, make touch control layer 120 can detect identical in fact sensed intensities with compensation.
In the above embodiments, be that the first surface 112 with touch-controlling interface layer 110 is that inner concave arc surface is an example, but the invention is not restricted to this.For instance, in one embodiment, shown in the contact panel 100f of Fig. 7, the first surface 112 of touch-control contact bed 110 also can be the evagination cambered surface with the second surface 142 of layer of compensation 140.Similarly, can design the various layers of compensation 140 described in preamble embodiment, not give unnecessary details in this according to the first surface 112 of touch-controlling interface layer 110.
In general; In the contact panel of convention; Because the surface of touch-controlling interface layer is generally non-horizontal surface; Therefore cause the detected sensed intensities of touch control layer to change and different, cause the sensing signal error or need proofreading and correct through complicated circuitry signal processing more according to the thickness of its top touch-control contact bed.For instance, difference is that the capacitance that the thickness of glass of 0.9mm possibly cause being produced has the difference about 10 times.Yet, in the present embodiment, between touch-controlling interface layer 110 and touch control layer 120, layer of compensation 140 is set, the capacitance difference that is caused with the first radian R1 that compensates by the second radian R2 of layer of compensation 140 and dielectric coefficient because of touch-control contact bed 110.In detail; The electric capacity that layer of compensation 140 and touch-controlling interface layer 110 produce respectively can add with parallel way to be taken advantage of; The capacitance difference that is produced when touch-controlling interface layer 110 only being arranged with compensation, and then minimize the capacitance difference that uneven surface caused because of touch-controlling interface layer 110.Thus, it is identical in fact or close to make that touch control layer 120 detects from the sensed intensities of the first surface 112 of touch-control contact bed 110.That is to say that no matter at the touch-control that where carries out of touch-controlling interface layer 110, touch control layer 120 can detect similar capacitance variation, therefore can confirm position of touch accurately.Therefore, contact panel 100 ~ 100f has favorable sensing capacity.
