Description of the Invention: [Technical Field] The present invention relates to a portable communication device and a method for adjusting a plurality of touch signals, and in particular to a method near a plurality of touch points, which is different from A portable communication device such as a relative position signal of a touch point and a method for adjusting the plurality of touch signals. [Prior Art] ® With the development of electronic communication technology, portable devices such as mobile phones, smart phones or personal digital assistants (PDAs) have become indispensable in modern human life. Supplies. In order to attract the attention of consumers, the manufacturers of the various factories have a place in the market for the products they produce, and they have developed new portable devices with special functions and convenient operation. Today, high-performance mobile phones, personal digital assistants or smart phones have many touch keyboards. Different from the hardware keyboard, some touch control keyboards are used to execute the software mode, and a keyboard is displayed directly on the display module of the communication device, so that the user only needs to touch when typing or performing other function selection. You can select the touch point on the control keyboard. However, portable communication devices such as mobile phones, personal digital assistants, or smart phones] have a common-purpose (four)', that is, the size of the display panel of the display module is smaller when the function option is smaller. The shirt makes it impossible for the user to confirm whether the selected graphic is too small, and the option is often used. In addition, because of the function of the horse to confirm from the visual way which is the finger _ 5 201025084 points touched the display module. Therefore, when a user uses a conventional portable communication device, it often happens that a function option that is not selected is accidentally touched. Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a user performing a touch operation on a conventional portable communication device. Figure 1 shows a portable communication device 1 and a subject 13 to be tested, i.e., a user's finger. The portable communication device 1 includes a display module 11 including a message display area 121 and a plurality of function options 123. In this example, the plural function option 123 is a touch keyboard. When the user wants to use the touch keyboard for typing or function selection, just touch the touch keyboard. As can be seen from Fig. 1, the keys of the touch keyboard are small and closely arranged, and the area of the user's fingers is relatively large. As far as the average user is concerned, whether the finger is used or the other finger is used for the touch operation, it is easy to cause a false touch. For example, in the first figure, when the user wants to select the letter "m" in the touch keyboard, since the area of the finger is much larger than the area of the letter "m", the touch is often pressed together. The other buttons around the letter "m" may be the letter "j", the letter "k" or the letter "η", resulting in a false touch. Therefore, a portable communication device can effectively determine the function options that the user really wants to touch when using a finger or other object to be tested to perform a touch of a small size option, and effectively reduce the false touch. Occurrence is one of the most important topics at present.

To achieve the above objective, the present invention provides a portable communication device including a touch module and a processing module. The touch module has a plurality of touch points (pixels) for sensing a touch operation of the object to be tested, so that the touched touch points generate a plurality of touch signals, which represent the touched Wait for the location of the touch point. The processing module 7 201025084 generates a relative position signal different from one of the touch points due to the plurality of touch signals. Another object of the present invention is to provide a method for adjusting a plurality of touch signals for use in a portable communication device. The method directly triggers one of the functions of the portable communication device or effectively determines one of the functions desired by the user by sensing a touch operation of the object to be tested, and driving the function of the portable communication device near the touch position of the object to be tested. In this way, the user can clearly know the function options that he or she will select to avoid accidental touch. In order to achieve the above object, the present invention provides a method for adjusting a plurality of touch signals, comprising the steps of: (a) sensing a plurality of touch points touched by a touch operation of an object to be tested; (b) according to the touch a handle that calculates a relative position different from one of the touch points; and (c) triggers a function of the portable communication device according to the calculation result of the step (b). The objects and advantages of the present invention, as well as the technical means and embodiments of the present invention, will be apparent to those skilled in the art of the present invention. The invention is explained in relation to a portable communication device and a method for adjusting a plurality of touch signals. Through a touch module and a processing module, the user can directly identify the user's desired touch options according to the area and distribution of the user's finger or other object to be tested and a display module. When the touch is touched, one of the functions of the portable communication device is directly triggered, or an indicator is displayed according to the relative position signal to trigger one of the functions of the portable communication device. However, the embodiments of the present invention are not intended to limit the invention to any specific environment, application, or special mode as described in the embodiments. Therefore, the description of the embodiments is only for the purpose of illustrating the invention, and is not intended to limit the invention. It should be noted that in the following embodiments and drawings, elements that are not directly related to the present invention have been omitted and are not shown. For ease of understanding, the dimensional relationships between the various components are shown in a somewhat exaggerated proportion. Please refer to FIG. 2, which is a schematic diagram showing the internal circuit of the first embodiment of the portable communication device of the present invention. The portable communication device includes a display module 26, a touch module 22, and a processing module 24. The display module 26 is adapted to display a plurality of function options, such as a call, a contact, a function selection, and the like. The touch module 22 has a plurality of touch points. When a device to be tested performs a touch operation on the portable communication device, the touch module 22 senses a touch operation of the object to be tested to be touched. The touch points generate a plurality of touch signals 2211' representing the positions of the touch points being touched. A more detailed description of the touch operation will be exemplified in the third and third figures and the description thereof. The processing module 24 generates a relative position signal 2411 of the touch point according to the plurality of touch signals 2211. The display module 26 is adapted to display the relative position signal 2411 according to the Φ. index. In detail, after the touch module 22 senses the touch operation of the object to be tested, a plurality of touch signals 2211 are generated according to the actual pressed position of the object to be tested, and the processing module 24 is adapted to the plurality of touch signals. A relative position signal 2411 is generated, and the relative position represented by the relative position signal will be slightly deviated from the actual (4) position of the object to be tested, so that the occupational inhibition group % is suitable for the relative position signal 'display-indicator. In this way, the user can clearly understand the functional options that he or she will select by observing the indicator. In other embodiments, the processing module 24 can also trigger one of the functions of the portable communication device directly from the relative position signal 24 of the touch points. Please refer to FIG. 3a, which illustrates a touch operation of a second embodiment of the portable communication device of the present invention. FIG. 3a illustrates a portable communication device 3 including a display module 31 for displaying a plurality of function options 323. For example, in the & display module 31, a plurality of function options 323, a touch keyboard are displayed. In the embodiment, the object to be tested 33 is a finger of the user. In other embodiments, the object to be tested may be a touch tool attached to the portable communication device, such as a stylus. When the user wants to press the letter of the touch keyboard, for example, the user wants to press the letter "h", the user first presses the area under the letter "h" and then touches the mode and group of the portable communication device 3 ( The figure is not shown, because it is located below the display module 31), the touch of the user's finger is detected, and the plurality of touch signals are displayed, which represent the position of the touched touch points. The module (not shown as being located below the display module 31) generates a relative position signal of the user's finger to the display mode and -a 31 in response to the plurality of touch signals. The relative position signal is used to cause the display module 31 to display a pointing pattern, such as indicator 324 at 3a. As can be seen from the figure, the indicator 324 is referred to as the letter "h", partially overlapping the letter and the indicator 324 is slightly offset from the user's pressing area. In this way, the user can clearly confirm the function that he or she will select. That is, the display module 31 is adapted to display the indicator in response to the position of the touch point being touched by the relative position signal. Please refer to the 3b ®, the material * is the third embodiment of the invention, the touch operation tf intention. The 3b material_portable communication device 4 includes a display module 41 for displaying a plurality of function options. For example, in the pictorial display module 41, a plurality of function options 423, which is a touch keyboard, are also displayed. In this embodiment, the object to be tested 43 is a finger of the user. In other embodiments, the object to be tested may also be a touch tool attached to the portable communication device, such as a stylus. . The third embodiment is mainly different from the second embodiment in that the display module 41 displays different fingerprints, as described below. When the user wants to press the letter of the touch keyboard, for example, the user wants to press the word "j", the user first roughly presses the area below the letter "j". At this time, the processing module of the portable communication device 4 (not shown, because it is located under the display module 41) generates a signal corresponding to the position of the user's finger to the display module 41 due to the plurality of touch signals. . The relative position signal is used to cause the display module 41 to display an indicator, such as the indicator 424 in FIG. 3b, which is to reverse the letter "j" covered by the user's fingertip (indicated by a thick black frame). As can be seen from the figure, the indicator 424 is a reversed white figure of the letter "j", which is suitable for indicating the letter "j", and the indicator 424 is slightly deviated from the user pressing area. In this way, the user is also able to clearly confirm the function that he or she will select. That is, the display module 41 is adapted to display the indicator within the position of the touched point that is touched by the relative position signal. Similarly, in other embodiments, the processing module may directly trigger the letter "j" due to the pressing of the user's finger. Referring to Fig. 4, Fig. 4 is a schematic diagram showing the internal circuit of the fourth embodiment of the portable communication device of the present invention. The maximum difference from the first embodiment is that the touch module 52 further includes a computing module 521 for calculating the distance and the position of the touched touch points according to the plurality of touch signals. To generate an average distance signal 5212 and an average pointing signal m3, respectively, and transmit to a processing module 54. The processing module 54 generates the relative position signal 5411 according to the average distance signal 5212 and the average pointing signal 5213'. Display module % displays an indicator based on the 201025084 relative position signal 5411. Please - and refer to Figure 6, which shows the touch operation diagram of the object to be tested. When the object to be tested touches the display module, the plurality of touch points of the touch module 42 are pressed to generate a plurality of touch signals. Figure 6 is a view showing the relative positions of the touched touch points 7〇 and the touch keyboards, wherein the touch keyboards near the touch points 7〇 are directly subtitled On the map 'for illustration. The arithmetic module can estimate an average distance according to the distance between the touched touch points 7〇', and the average distance can represent the area of the current touch object and the pressing position. The operational module 521 also generates an average distance signal 5212 accordingly. The computing module 521 can estimate an average pointing according to the distribution position of the touched touch points 70, and the average pointing can represent the direction of the current object to be touched. The arithmetic module 521 also generates an average pointing signal 5213 at this time. According to the above description, according to the average distance and the average pointing direction, the pressed position of the object to be tested can be known, which is approximately the letters "h", "j", "n" and "m" of the touch keyboard. Near the 'simultaneous touch direction is about right down to the top left. The processing module 54 can generate a phase-to-position signal 5411 according to the average distance signal 5212 and the average pointing signal 5213. The relative position signal 5411 is used to directly trigger a function of the portable communication device, such as a letter " h", or the display module 56 displays an indicator near the upper left of the touch points 70 that are touched. The indicator can be an indicator as described in the second embodiment; or as shown in the third embodiment, it is a reverse image. Figure 5 is a schematic diagram showing the internal circuit of the fifth embodiment of the portable communication device of the present invention. The greatest difference from the fourth embodiment is that the processing module 64 is configured to execute the functions of the computing module 521 as in the fourth embodiment. 12 201025084 ^ In this embodiment, the touch module 62 is like the touch module 22 of the first embodiment, and has a plurality of touch points (pixels) for sensing the touch operation of an object to be tested, so as to be The touch points are touched to generate a plurality of touch signals 6211 and transmitted to the processing module 64. The processing module 64 can generate a relative position signal 6411 according to the average distance signal and the average pointing signal. The relative position signal 6411 is used to directly trigger one of the functions of the portable communication device, or the display module 66 is enabled. An indicator is displayed near the touch points that are touched. The indicator may be an indicator as described in the second embodiment; or may be a reversed image as described in the third embodiment.
