Please refer to Fig. 6 and Fig. 7.Fig. 6 be contact panel 10 in user hand 100 close to time its each electric capacity schematic diagram, and Fig. 7 is the equivalent circuit diagram of the contact panel 10 of Fig. 6.Wherein, the electric capacity between the 3rd sensor pad 100 (i.e. receiving electrode) of patterned conductive layer 50 and the hand 110 of user is with C
frepresent, the electric capacity between emitting electrode layer 30 and multiple 3rd sensor pad 100 is with C
tX-RXrepresent, the electric capacity between emitting electrode layer 30 and earth terminal GND is with C
tXrepresent, the electric capacity between the 3rd sensor pad 100 of patterned conductive layer 50 and earth terminal GND is with C
rX-GNDrepresent, and emitting electrode layer 30 is electrically coupled to AC power V
tX.Suppose that the voltage of the 3rd sensor pad 100 is V
rX, and AC power V
tXfrequency be S, then voltage V
rXcan be expressed as:
From above-mentioned equation, if electric capacity C
tX-RXtoo large, then voltage V
rXintensity of variation can reduce.Because sensing control circuit 70 is according to voltage V
rXjudge whether that foreign object is close, if therefore voltage V
rXintensity of variation too low, then can have a strong impact on the sensitivity of contact panel 10 near sense.Therefore, for making contact panel 10 pairs of near sense have higher sensitivity, then can by reduction electric capacity C
tX-RXthe mode of capacitance reach.Moreover, due to electric capacity C
tX-RXcapacitance be directly proportional to useful area between emitting electrode layer 30 and multiple 3rd sensor pad 100, and to be inversely proportional to the spacing of emitting electrode layer 30 and multiple 3rd sensor pad 100, therefore in order to make electric capacity C
tX-RXthere is lower capacitance to improve the near sense sensitivity of contact panel 10, then by useful area between minimizing emitting electrode layer 30 and multiple 3rd sensor pad 100, or can reach by the mode of the spacing (i.e. the thickness of substrate 40) increasing emitting electrode layer 30 and multiple 3rd sensor pad 100.Refer again to Fig. 5.Because the 3rd sensor pad 100 is distributed in the surrounding zone A2 of patterned conductive layer 50, therefore between emitting electrode layer 30 and multiple 3rd sensor pad 100, useful area is not too large, therefore can effectively reduce electric capacity C
tX-RXcapacitance, and then make contact panel 10 have higher sensitivity near sense.In addition, electric capacity C
tX-RXcapacitance also can adjust by the ratio changed between the area of arbitrary electrode 106 and the area of arbitrary 3rd sensor pad 100, and the ratio between the area of the area of above-mentioned electrode 106 and the 3rd sensor pad 100 can between 0.2 to 0.9.The area of the 3rd sensor pad 100 corresponding to wherein larger ratio is usually less, and corresponding electric capacity C

tX-RXcapacitance also larger.
Above-mentioned electric capacity C
tX-RXcapacitance except except the above mode that makes the 3rd sensor pad 100 be distributed in the surrounding zone A2 of patterned conductive layer 50 reduces, also can reducing by the mode reducing emitting electrode layer 30 area.Please refer to Fig. 8, Fig. 8 is the emitting electrode layer 30 of one embodiment of the invention and the schematic diagram of patterned conductive layer 50.Wherein the area of emitting electrode layer 30 can be less than the area of patterned conductive layer 50, and reduces electric capacity C further
tX-RXcapacitance.Please refer to Fig. 9, Fig. 9 is the emitting electrode layer 30 of another embodiment of the present invention and the schematic diagram of patterned conductive layer 50.Wherein emitting electrode layer 30 has multiple 4th opening 32, and further reduces electric capacity C
tX-RXcapacitance.Wherein, the position of the 4th opening 32 is not limited to the position that Fig. 9 illustrates.
In addition, because contact panel is often used in hand-held action device (as: mobile phone, lithographic plate computer etc.), and during user's hand-held action device, usually can touch the frame of running gear, and make above-mentioned electric capacity C
fcapacitance hold the edge of contact panel 10 and influenced because of user.In addition, current hand-held action device for main flow, more makes above-mentioned for electric capacity C with narrow frame
fcapacitance very easily hold the impact at contact panel 10 edge by user.For improving the problems referred to above, in an embodiment of the present invention, electrode 106 is as ground-electrode.In the case, if user holds the edge of contact panel 10, then user hand can because of electrode 106 ground connection, so can avoid above-mentioned electric capacity C
fcapacitance hold the edge of contact panel 10 and influenced because of user, and then the near sense sensitivity of contact panel 10 can be avoided to hold the edge of contact panel 10 and influenced because of user.
