  Despite being a resistive film type or a capacitive type, a touch panel that is currently widely used receives a signal from a finger or a stylus and changes to coordinates through calculation to achieve a desired operation ability.

  A touch panel is a human-machine interface device that is easy to operate, and is widely used in mobile devices such as mobile phones, tablet computers, and notebook computers. Therefore, it is believed that the touch panel is limited to being a human machine interface device.

  The present invention was submitted to increase the new functions of the touch panel and enhance the convenience of daily life for human beings. For example, the present invention can provide a solution when there is no battery power supply of a mobile phone or when there is no transmission medium when sending pictures and data.

  The details of the embodiment of the present invention are as follows. However, in addition to what has been described below, the present invention can be widely applied to other embodiments. That is, the scope of the present invention is not limited to the submitted embodiments, but is the scope of application of the present invention.

  In devices such as mobile phones, tablet computers, instruments, and operation panels that are widely used at present, the operation panel 10 includes a touch panel 11, a display panel 12, and a processor 13. As shown. When the surface of the touch panel 11 receives an external force from the outside (for example, an external force due to pressing or contact with an external object or an external force due to pressing or contact with an external object having a charge), the touch panel 11 senses the position of the external force, and The processor 13 performs arithmetic processing to convert it into position coordinates (usually coordinates in the X-direction and Y-direction), and the position and function corresponding to the screen of the display 12 (for example, one of the functions in the screen menu) To display a screen corresponding to the display panel 12. In this embodiment, the external object refers to a finger or a stylus.

  This case uses a line on a touch panel, for example, a line on a projected capacitive touch panel, the line includes a first line and a second line, and the first line is an X-direction line. The second line is a Y-direction line, and is called a column pattern (row trace) 22. In addition to the original touch control function of transmitting the first signal based on the coordinates of the touch panel to the processor 13, the input device of the touch panel 11 can be changed to a new output device. In other words, the touch panel can achieve the purpose of sending the second signal by wirelessly transmitting the second signal to the receiver. In the present embodiment, the receiver is a mobile device. For example, in the first situation, the touch panel 11 provides an original touch control operation, whereas in the second situation, the touch panel 11 can perform other functions outside. Therefore, the present invention uses a method of dividing time. In other words, the time required for the input function of the original touch panel 11 is used, and this time zone is divided into a first time zone and a second time zone. The zone is used when the touch panel 11 sends a second signal to the outside, or when the touch panel 11 receives a third signal from the outside. In addition, by using the first time zone and the second time zone in combination in a periodic manner, the touch panel 11 can provide a new use of reception / transmission and can maintain the original touch control function. For example, in the first time zone, the row pattern 21 and the column pattern 22 of the touch panel 11 can detect coordinates generated by the external force of the touch panel 11 and change the coordinates to a first signal (which can be referred to as a control signal). The first signal is received and processed by the processor 13. Also, in the second time zone, the row pattern 21 and the column pattern 22 have antenna functions, and the second signal of the touch panel 11 is sent out wirelessly, and the second signal is generated from the processor 13, It is sent outside through the row pattern 21 and the column pattern 22. Alternatively, a third signal from an external device is received through the reception function of the row pattern 21 and the column pattern 22.

  The aforementioned time zone can be divided into a first time zone, a second time zone, and a third time zone. In the second time zone, the row pattern 21 and the column pattern 22 having antenna function send the second signal of the touch panel 11 wirelessly, and the second signal is generated from the processor 13, and the row pattern 21 and the column pattern 22 Send out through pattern 22. In the third time zone, the row pattern 21 and the column pattern 22 having the reception ability receive the third signal from the external device.

  The second signal is a signal having energy or data, in which the signal having energy includes electricity or radiation, and the signal having data is a digital record. In practical applications, the second signal can be designed according to the desired capabilities of the mobile device. For example, when the mobile device is a mobile phone, when there is no battery power, the touch panel 11 of the present invention is used to control the transmission of the second signal by the processor 13 and charge the mobile phone in a wireless manner. it can. For example, in the case where the mobile device is a USB drive, when it is desired to back up a digital record and hand it over to another person, the touch panel 11 of the present invention is used to control the transmission of the second signal by the processor 13 and wirelessly. The backed up digital of the USB drive can be transmitted, and the touch panel can receive a third signal from the USB drive in a wireless manner. For example, when the mobile device has two different styluses, the touch panel 11 of the present invention is used, the processor 13 controls the transmission of the second signal, and identification numbers are respectively assigned to the two styluses. When the stylus comes into contact with the touch panel 11 at the same or different time point, a third signal sent by the stylus can be received by a wireless method, and a command to the touch panel 11 can be taken out.

  Refer to the cross-sectional view shown on the touch panel 11 in FIG. The touch panel 11 includes a vertical row pattern 21 and a horizontal column pattern 22. The row pattern 21 and the column pattern 22 are on the substrate 23. According to the embodiment of the present invention, the row pattern 21 and the column pattern 22 are made of a transparent conductive material, and the transparent conductive material is made of indium tin oxide (ITO), graphene (Graphene), Al-doped zinc oxide ( Al-doped ZnO, AZO), zinc oxide (Zinc oxide), antimony (ATO), gallium-doped zinc oxide (Ga Doped ZnO, GZO), F-doped tin oxide (F Doped SnO2, FTO), and combinations of these It is one of the things that are being done. It may be made of an opaque conductive material and is made of nano silver wire or metal mesh. The substrate 23 is a glass substrate or a plastic substrate. An insulator 24 is provided between the row pattern 21 and the column pattern 22 so that the row pattern 21 and the column pattern 22 are not electrically conducted.

  Taking a projected capacitive touch panel as an example, in the first time zone, the touch panel 11 is a signal receiving device, and the arrangement of the power line 31 having the electric field of the row pattern 21 and the column pattern 22 is shown in FIG. As shown. As shown in FIG. 3A, the row pattern 21 and the column pattern 22 are disposed on the surface of the substrate 23, and the insulator 24 is disposed between the row pattern 21 and the column pattern 22. When the external object 32 applies an external force to a place on the surface of the touch panel 11, the power line 31 is blocked, and the power line 31 affects the detection energy of the row pattern 21 in the place. In the second time zone, the touch panel 11 is a signal output device, and when transmitting the second signal, the power line 31 is sent out from the column pattern 22 (as shown in FIG. 3B), and the row pattern The signal is sent to the signal receiver 33 simultaneously with the column pattern 22 and the row pattern 21 (as shown in FIG. 3D). In the third time zone, when the touch panel 11 is a signal input device and receives a third signal from the transmitter 34, the power line 31 receives from the column pattern 22 (as shown in FIG. 3E), A signal is received from the row pattern 21 (as shown in FIG. 3F) or simultaneously with the column pattern 22 and the row pattern 21 (as shown in FIG. 3G).

  Refer to the circuit diagram of the touch panel 11 shown in Fig. 4A. When the touch panel 11 is a projected capacitive touch panel, the equivalent circuit is shown in FIG. 4B, and the intersection of the row pattern 21 and the column pattern 22 is a sensing pixel 41 of the touch panel 11, one sensing The pixel 41 is formed by one capacitor device 42. Every row pattern 21 and column pattern 22 is electrically connected to the processor 13, respectively. Taking a resistive touch panel as an example, when the touch panel 11 performs the original function, when an external object 32 touches a certain place of the touch panel 11 with, for example, a finger or a stylus, A signal indicating a change in resistivity of the column pattern 22 is received by the processor 13, and the processor 13 thereby determines a corresponding coordinate of the touch panel 11. Taking a projected capacitive touch panel as an example, when the touch panel 11 is touched with an external object 32 such as a finger or a stylus, the capacitance change signals of the row pattern 21 and the column pattern 22 are output. Received by the processor 13, the processor 13 thereby determines the corresponding coordinates of the touch panel 11. The shape and arrangement of the row pattern 21 and the column pattern 22 can be designed according to the needs of the resistive touch panel or the projected capacitive touch panel.

  Taking a projected capacitive touch panel as an example, the dotted line in this figure is the reference voltage 50 as shown in FIG. 5A. For example, in the first time zone of the first cycle, when the touch panel 11 does not detect an external force, the processor 13 sends a first signal 51, and the voltage between the row pattern 21 and the column pattern 22 at this time is a reference. The voltage is higher than 50. Thereafter, in the second time zone of the first cycle, a second signal 52 is generated from the processor 13 and transmitted outside through the row pattern 21 and the column pattern 22 of the touch panel. Thereafter, in the third time zone of the first cycle, the processor 13 receives the third signal 53 from the outside through the row pattern 21, the column pattern 22, or the row pattern 21 and the column pattern 22 of the touch panel.

  According to this embodiment, when the touch operation on the touch panel 11 is not used, the first time zone can be canceled and only the second time zone function can be executed on the touch panel 11. That is, a second signal 52 is generated from the processor 13 and transmitted outside through the row pattern 21 and the column pattern 22 of the touch panel. Alternatively, the processor 13 receives the third signal 53 from the outside through the row pattern 21, the column pattern 22, or the row pattern 21 and the column pattern 22 of the touch panel.

  The second and third signals sent outside the above are always designed according to the signal type. For example, both of the second and third signals are designed as a fifth signal 56 as shown in FIG. 5B.

  According to the embodiment of the present case, the third line (not shown) and the fourth line (not shown in the figure) are located in the area that originally has no line in the touch panel 11 and the area called the ineffective area. This cross-sectional view is the same as in FIG. 2 except that the third line replaces the first line and the fourth line replaces the second line. At that time, the first and second lines in the first time zone and the third and fourth lines in the second time zone are different lines.

  According to the embodiment of the present case, a time zone having any desired cycle can be designed for the time division between the first time zone and the second time zone. For example, the length of the first time zone must correspond to the touch operation performance. Furthermore, the fourth and fifth time zones can be divided within the same period depending on the desired function.

  Refer to Figure 6A. This is an example in which the touch panel 11 is used to charge the external stylus 61. The stylus 61 includes a power module 62 and a drive line 63. When the amount of electricity of the power module 62 is low, the power line 64 having the row pattern 21 and the column pattern 22 of the touch panel 11 is formed through the drive line 63, and the electric field is converted into electricity. To achieve the purpose of charging the stylus 61.

  Refer to Figure 6B. This is an embodiment in which the stylus 71 is used. The stylus 71 includes a power module 72, a drive line 73 and a communication storage block 74. The stylus 71 receives a frequency pulse having a power line 75 from the row pattern 21 and the column pattern 22, the frequency pulse has an identification number of the stylus 71, and the identification number is stored in the communication storage block 7, This is the basis when the processor 13 identifies the stylus 71. Therefore, the touch panel 11 causes the processor 13 to detect coordinates corresponding to the processor 13 when the stylus 71 applies an external force to the touch panel 11 in the first time zone, and the touch panel 11 sends an identification number to the processor 13. The processor 13 can identify which stylus 71 gives an external force to the touch panel 11 by an identification number. This ability and advantage becomes clearer with more than one stylus.

  Refer to Figure 6C. This is another embodiment of the present application and is applied to the stylus 81. The stylus 81 includes a power module 82, a drive line 83 and a storage device 84. In this embodiment, the output signal having the power line 85 of the touch panel 11 is a data signal based on the same principle as the above-described embodiment, and the data signal is converted and stored in the stylus 81. This embodiment can also be applied to USB drives.
