The existing touch panels are all single-sided structures, and only allow the user to operate on a single side. The main constituent elements are formed on a substrate to form a sensing layer on a single layer #, and then set on the sensing layer. A protective layer (c〇v II!ens) is used for decoration and protection of the protective layer. When the user touches this: when the touch panel is used, the sensing chip can be detected by the peripheral device (the touch voltage is detected and the coordinate of the touch point is determined by φ. Since the touch panel can only be Touching the magic in a single direction, _ makes the application of the touch panel inevitably limited. Therefore, the touch panel can be used as an operation interface and receive different control signals at the same time, which can effectively expand its use field and Commercial value. ° [New content] The main purpose of this creation is to provide a double-sided touch panel with two sides s as an operation interface to receive the user's touch operation. 3 M424544 To accomplish the above purpose, the two sides of the creation The touch panel includes a first substrate unit and a second substrate unit that are oppositely bonded: the first substrate unit includes a first substrate and a first sensing layer formed on the surface thereof. a first _ sensing electrode and a plurality of first-shielding electrodes, wherein the first shielding electrodes are grounded; the second substrate unit comprises a second substrate and a second sensing layer formed on the surface thereof, the second weiku The alpha layer is opposite to the first sensing layer and has a plurality of second sensing electrodes and a plurality of second shielding electrodes, wherein the second shielding electrodes are grounded; ” the sensing electrodes and the second shielding electrodes are correspondingly overlapped, # The first-shielding electrode and the second sensing electrode are correspondingly overlapped. When the user touches the mid-surface, for example, the touch-based phase unit, the first sensing layer is induced by the self-electric valley. Detected in the X direction: sensing signal 'but because the Υ direction is shielded by the first shielding electrode, there is no side that breaks the first substrate unit (if the front side is touched. According to the weighting calculation of each first-induction electrode signal strength, Calculate the position of the touch point X direction. Take the test of the base flute, take the mutual capacitance sensing method, and detect the position of the signal change amount 2 between the 7-electrode electrode and the second sensing electrode, and combine the position of the χ and γ directions to obtain the touch.
