Description of the Invention: [Technical Field] The present invention relates to a signal processing method for a touch panel, and more particularly to a signal processing method for a composite touch panel. [Prior Art] In recent years, with the rise of information appliance (IA) products, such as mobile phones, digital cameras, satellite navigation and positioning devices (gl〇bal (four) Gang • system GPS) ' A#t> gt | (personal digital assistant 5 PDA) and other portable electronic devices are becoming more and more popular. And such information home appliances are constantly being developed in the direction of easy operation, small size and large screen size, especially for the volume and screen of portable electronic products. The size requirements are more stringent. Due to the significant reduction in the production cost of touchpads, many consumer electronic products integrate the touch panel Weijing display panel and replace the financial peripherals such as keyboards or mice to interact with portable information appliances. Input to omit the space required by the keyboard or the operation keys, thus expanding the configurable area of the screen and making it easier for the user to control. The conventional touch panels can be roughly classified into capacitive, inductive, resistive, infrared, and ultrasonic touch panels. The capacitive touch panel and the inductive touch panel are the most common products. In the case of a capacitive touch panel, the capacitive touch panel can provide a user with multi-touch control of the portable electronic device, and has a more user-friendly operation type. Therefore, the capacitive touch panel has gradually become a market. The mainstream trend. However, the electric 201118679 ^ touch panel dump · f (such as the user's finger) touch the touch panel material heart Γ operation ' 0 攸 users can not carry gloves or through the material ^ 'Qi Shi electric Valley The touch panel is applied with a trigger command. With the inductive touch panel, the money can be passed through the digital pen to touch the H-hand. The new pen has a “sensing chip”. When the position is near the touch panel, the sensing chip is transmitted, the signal is transmitted to the touch surface, and the touch panel accepts the digital pen on the touch panel. The trace, in turn, sends a control signal. As mentioned above, the rhyme-control panel towel, the capacitive touch panel can provide the =2 control mode, but it can't be _ user's shirt on the touch panel moves 2, that is, the money can not be bribed On the capacitive touch panel: write the text. Inductive touch panels can be used as a good curve track on the touch panel, but they cannot be executed. Therefore, the user's mouth = f - the type of panel inspection (four) control, there is no advantage of the capacitive touch panel brittle inductive touch panel, resulting in the real demand of the meal and the user. As a result, the overall ship has limitations, and it is unable to satisfy the touch surface of the touch screen that has been touched by the current financial manufacturer and the touch of electricity. === Control = still switch the capacitive touch mode or The electric 4 type touch reduces 'and _ when performing two kinds of touch work L. The above = board = τ capacitive touch panel structure and the inductive touch panel structure axis early - sheet panel, which is a structural improvement, if at the same time The function of performing capacitive touch mode and inductive touch mode is very likely. ___ 201118679 The occurrence of malfunctions is not convenient in use. SUMMARY OF THE INVENTION The present invention provides a signal processing green of a composite touch panel, so that the touch panel of the conventional portable electronic device cannot simultaneously perform the capacitive touch mode and the inductive touch mode. Will greatly test the problem of misoperation. The signal processing method of the composite touch panel disclosed in the present invention is configured to simultaneously receive the first touch signal of the first interface and the second touch signal of the second interface, and firstly obtain an effective trigger area of the touch panel. The effective trigger area is set—the first mode block and the second mode block, and the touch gamma generated by the first interface or the first interface is obtained on the effective trigger area. Then, the touch signal of the trigger point is the dipole signal of the first touch signal, and the position of the judgment point is located in the first mode block or the second mode block. "If the trigger point is sent by the first interface and falls within the first mode block, the trigger point executes the mode "the fine point is sent by the second interface and falls within the second mode block, and the trigger point executes the second mode. . The invention is characterized in that the touch panel of the present invention can simultaneously perform the pen writing touch by reading the touch signal of the point on the hard panel and the miscellaneous 'm pin of the position. Mode or finger touch mode, and when the middle touch mode is executed, 'there is no mutual interference between the two touch modes, effectively avoiding the use of the touch panel if the touch panel is designed by the hardware and has the pen writing touch mode and the finger. The touch mode 'causes it to lead the secret county. The description of the present invention and the following description of the embodiments of the present invention are intended to exemplify the invention and to provide a further explanation of the scope of the invention. [Embodiment] - "Fig. 1" and "2A" to "2C" are flowcharts showing the steps and operations of the first embodiment of the present invention. As shown in the "Figure 1", and in conjunction with the operation of "2A" to "2c", the signal processing method of the composite touch panel of the first riding of the county is first. The control panel, the parallel-touch panel 200 can simultaneously receive the __ touch signal of the first interface and the second touch signal of the second interface 步骤 (step _ ^ the first interface (10) described in this embodiment For example, the digital pen can be used to send a frequency to the touch panel 2〇〇, so that the touch panel finely detects the change of the frequency, thereby generating the first touch signal, and the second interface 32 can be - the user's finger, and the capacitance value of the touch panel (4) can be changed to generate the second touch signal. Those skilled in the art can also choose the different type and the method of generating the touch signal is different. The number of control interfaces can also be increased or decreased according to the actual use requirements, and is not limited to this embodiment. Among them, the touch dance action of the digital pen can be roughly divided into electromagnetic type, voltage type, and capacitive type, and currently The touch sensing action is performed on the touch panel by electromagnetic sensing. The nib portion of the digital pen and the magnetic field generated by the touch panel 200 are in contact with each other in a contact or non-contact manner, so that the digital pen generates a touch signal at a corresponding position of the touch panel 2 。. An effective trigger area of the panel 200, and a first mode block 210 and a second mode block 22〇 are set in the effective trigger area 201118679. (Step 11). In detail, the first mode block of this embodiment The first mode block 220 is a finger touch block and can only detect The touch signal of the change of the capacitance value generated by the second interface 320 (ie, the user's finger) is measured. As shown in the "2nd 8th", the first mode block 21 is set in the effective trigger area. When the two-mode block 220 is obtained, the boundary coordinate values of the first mode block 21〇, the remaining values, the P3, the P4, and the boundary value values tl, t2, t3, and t4 of the second mode block 220 are obtained, so as to be accurate. Defining the first mode block 21G and the second mode block 22〇 However, the effective trigger area of the touch panel 200 of the present embodiment divides the blocks 210 and 22 of two different operation modes, but is not limited thereto, and can be designed according to actual needs and needs. The number and position of the settings are increased or decreased. * Please continue to refer to the "i" to "2C". When the first interface 31 or the interface 320 is triggered on the effective trigger area of the touch panel 2 (8) During the action, the touch panel 20 (M detects and obtains the trigger point 23 产生 generated by the first interface or the second interface 320 on the effective trigger area (step 12 〇), and for this trigger point 23 〇 The touch signal and the position are judged (step chat. For example, as shown in FIG. 2B), when the first interface 31 is generated within the flip of the first mode block 210, the trigger point 23〇 is generated. The frequency change of the trigger point 230 is caused by the frequency emitted by the first interface 310, and it is determined that the trigger point 23〇 position is indeed within the first mode block 21〇 and the trigger point is determined to be an effective point ( Step 15)), so that the touch panel is correspondingly executed by the first interface 31 〇 2 01118679 Performs the first mode of pen writing control (step (5)); as shown in "2C", when the second interface 320 is generated within the range of the second module block 22G - trigger point shift:, the trigger point 23G The generated capacitance change is caused by the touch of the second interface 32 (), and it is determined that the position of the trigger point 230 does fall within the second mode block, and then the trigger point 23 is determined to be an effective point (step Let's talk about the touch panel. Corresponding to the second mode of performing finger manipulation with the second interface 32G (step kiss. When it is determined that the first interface 310 generates a trigger point within the range of the second mode block 22, the second mode block 22 receives only the touch signal generated by the second interface to change the electric valley value, thereby discriminating The frequency of this trigger point 230 does not match the position. The effective mode input point of the first mode block 22Q; or when the second interface 320 determines that the trigger point is generated within the range of the first mode block 21〇, since the first mode block 210 only receives the first interface 31 The touch signal corresponding to the frequency change of 〇 is therefore fine--the trigger point 23() _ rate and position do not conform to the effective control input point of the first mode block 210. Therefore, the trigger points 230 of the above two cases are all judged as invalid points (step 14〇), and the touch panel does not perform any manipulation action (step 141), thereby effectively preventing the occurrence of malfunction. As shown in "Figure 3" and in conjunction with the operation of Figure 4, the signal processing unit of the composite touch panel of the second embodiment of the present invention and the first implementation of the present month are implemented. The first mode block 2 i 〇 and the second mode area of the touch panel of the first embodiment of the present invention are similarly fixed, and the touch panel of the second embodiment can be dynamically adjusted. The range size of the first mode block 210 and the second mode block 220 (step 160). 201118679 The second example is described by the manipulation action of the second interface 32〇. When the operation position of the second interface is adjacent to the boundary of the second mode block 22G (the right boundary formed by the coordinates t2 and ^), the handle-handle type The block no is expanded according to the central position of the second interface 3, for example; the enlarged fine can be fixedly built into the product, or the user can be used to enter the (four) degree can to meet the needs of the user.
