Charge the phone. For example, when the portable device is a portable device, if the file is backed up and delivered to another person, the touch panel 11 of the present invention can be utilized, and the processor 13 controls the transmission of the second signal. The wirelessly transmitting the copied file or data to the portable device, the touch panel can also wirelessly receive the third signal transmitted by the portable device; for example, when the portable device is two different In the stylus, in addition to the touch panel 11 of the present invention, the processor 13 controls the transmission of the second signal, and the two styluses are given different views. The identification number is obtained by the two styluses when the touch panel 11 is touched at the same or different times, and the third stylus is transmitted by the stylus according to the definition and wirelessly. The command placed on the touch panel 11.

Please refer to FIG. 2 , which is a schematic cross-sectional view of a touch panel 11 . The touch panel 11 includes a longitudinal line 21 and a lateral column line 22. The row line 21 and the column line 22 are formed on the substrate 23, respectively. According to an embodiment of the present invention, the row line 21 and the column line 22 may be a transparent conductor material, such as indium tin oxide (ITO), graphene (Graphene), and aluminum-doped zinc oxide (Al). -doped ZnO, AZO), zinc oxide (ZnO), an antimony doped tin oxide (ATO), a gallium doped zinc oxide (Ga Doped ZnO, GZO), a fluorine doped tin dioxide (F Doped SnO2, One of the groups formed by the FTO) or a combination thereof may also be an opaque conductor material such as a Nano Silver wire or a metal mesh. The substrate 23 can be a glass substrate or a plastic substrate. An insulating layer 24 is disposed between the row line 21 and the column line 22 to prevent electrical conduction between the row line 21 and the column line 22.

For example, in the first time period, the touch panel 11 is used as a signal receiving device, and the power line 31 of the electric field carried by the line 21 and the column line 22 is distributed as the 3A. The figure shows. As shown in FIG. 3A, the row line 21 and the column line 22 are disposed on the surface of the substrate 23, and the insulating layer 24 is disposed between the row line 21 and the column line 22. When an external object 32 When an external force is applied to a position on the surface of the touch panel 11, the power line 31 is blocked, and the power line 31 affects the induced energy of the line 21 at the position. During the second time period, the touch panel 11 is used as a signal output device to externally transmit the second signal. At this time, the power line 31 can be externally emitted by the column line 22 (as shown in FIG. 3B).
