Description of the Invention: Technical Field The present invention relates to a touch panel, and more particularly to an integrated touch panel having a plurality of touch panels and a control method thereof. [Prior Art] In recent years, the application of touch panels has become more and more widespread. Whether it is a personal computer, a notebook computer, a personal digital assistant (PDA) or a mobile phone, the function of the touch panel is added. The technical principle of the touch panel is to detect the voltage, current, sound wave or infrared light according to different sensing methods when the finger or other medium touches the screen, thereby measuring the coordinate position of the touch point. For example, the resistance type is to use the potential difference between the upper and lower electrodes to calculate the position of the pressure point to detect the touch point. However, different types of touch panels have different positional recognition at the touch point. For example, a resistive touch panel is lower than a capacitive touch panel. When using the touch panel, the user will have different recognition requirements depending on the φ program used. The disadvantage of the capacitive touch panel is that it consumes energy and must be limited to fingers or a grounding wire stylus. The advantage of rain is that it can accept multi-finger touch, and only needs to touch the panel. The capacitive touch panel is Sensitive should be sensitive. In contrast, a resistive touch panel can use both a finger and a touch device that can be pressed against it, but the resistive touch can only accept single-finger touch and requires pressure touch. Both panels have limitations on the use of the user, which is quite inconvenient.

[Embodiment] Fig. 1 is a schematic view showing a display panel having an integrated touch panel according to the present invention. In Fig. 1, only some of the required components are shown, and other driving circuits such as the Φ display panel or the detection circuit of the touch panel are omitted. The resistive touch panel 11 is disposed above the capacitive touch panel 12 , and the display panel 10 is disposed under the capacitive touch panel 12 . The resistive touch panel 11 is provided with a scratch-resistant layer for protecting the resistive touch panel 11. An adhesive layer is disposed between the resistive touch panel 11 and the capacitive touch panel 12 for bonding the resistive touch panel 11 and the capacitive touch panel 12. The multiplexer 15 is coupled to the capacitive touch panel 12 via the analog digital converters 13 and 14 and the resistive touch panel 11 respectively. The processing unit 16 selects to use the resistive touch panel or the 0506-A41752-TW/fmal 7 201015397 capacitive touch panel according to the properties of the application. It should be noted that the processing unit 16 can be selected to be closed without selection. Go to the touch panel, or do not close the touch panel that is not selected. . Processing unit 16 may be implemented by software or by hardware. If a program executed using the electronic device of Fig. 1 requires a high-sensitivity touch mode, the processing unit 16 uses the capacitive touch panel. If the program executed using the electronic device of Fig. 1 requires a low-sensitivity touch mode, the processing unit 16 uses the capacitive touch panel. In this embodiment, the high-sensitivity touch mode refers to the difference between the coordinate position of the actual touch point on the touch panel and the coordinate position of the touch point obtained by the detecting circuit on the touch panel. It is less than a predetermined error. For example, the horizontal coordinate of the coordinate position of the touch point obtained by the detecting circuit on the touch panel and the horizontal coordinate of the coordinate position of the vertical coordinate and the actual touch point are different from the vertical coordinate by a predetermined distance. within. On the other hand, the low-sensitivity touch mode means that the difference between the coordinate position of the actual touch point on the touch panel and the coordinate position of the touch point obtained by the detecting circuit on the touch panel is greater than a predetermined error. . For example, the horizontal coordinate of the coordinate position of the touch point obtained by the detecting circuit on the touch panel® and the horizontal coordinate of the vertical coordinate and the coordinate position of the actual touch point are larger than the distance of the vertical coordinate. distance. Fig. 2 is a flow chart showing a control method of an electronic device having a display panel of an integrated touch panel according to the present invention. The display panel with the integrated touch panel in this flowchart is as shown in Fig. 1. In step S21, a touch panel management program is started first. Then, when the electronic device is executing the application, the process proceeds to step S22, and the touch panel management program determines the required recognition mode of the application 0506-A41752-TW/final 201015397 program. If the application is to make a low-recognition touch mode, the touch panel management program selects the resistive touch panel for use by the application (step 4). When the application uses a high-sensitivity touch mode, the touch panel management program selects the capacitive touch panel for use by the application (step S23). In this embodiment, if the application must use the map map information, the application uses a high-sensitivity touch mode. These applications may be navigation system applications, Global Positioning System (OPS) related applications or image processing applications. In another embodiment, the user can directly set the touch mode of the application in the electronic device through the touch panel management program and store it in a data library.

The control software 41 may be a software executed by an electronic device using an integrated touch panel such as a computer, a mobile phone or a PDA. For example, the capacitive touch panel 12 has a high precision. Therefore, when the control software receives the signal transmitted from the touch panel to belong to a thin line or a thin point, the control software 41 selects the capacitive touch panel 12. On the other hand, if the control software receives the signal sent from the touch panel transmission to the thick line or the thick point, the control software 41 selects the resistive touch panel 11.
