DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for avoiding malfunctions, and in particular to a method for avoiding malfunctions with a high degree of correctness. [Prior Art] 触控 Touch panel is one of the most popular technologies today, and it is used in many fields, such as consumer electronics such as mobile phones or multimedia players. For a mobile phone using a touch panel, a call is often caused by a user's face touching, for example, causing the mobile phone to accidentally delete certain important data, and make another call or call during the call. The state of the call, such as the disconnection, causes inconvenience in use. SUMMARY OF THE INVENTION The present invention relates to a method for avoiding malfunctions. When the portable electronic device is in a call state, it is correctly determined whether the touch panel is touched by the user's face to avoid the portable electronic device. In response to the invention, it is proposed that the county generates a malfunction for a portable electronic device having a touch panel, ί. Whether the portable electronic device is in the -call state is in a call state, and the touch panel is judged to be. The right touch panel is touched' to determine whether the touch panel is touched. The area of 201019695 is greater than a predetermined area. If the area touched on the touch panel is larger than the predetermined area, the touch panel does not trigger the corresponding function, so that the portable electronic device is still in a call state. ▲ In order to make the above-mentioned contents of the present invention more obvious, the following detailed description of the preferred embodiment and the accompanying drawings will be described in detail as follows: [Embodiment] This (4) provides a kind of avoidance of malfunction. The method is to correctly determine whether the touch panel is touched by the user's face when the portable electronic device is in a call state, so as to prevent the portable electronic device from malfunctioning. Referring to Figure 1, a flow chart of a method for avoiding malfunctions in accordance with a preferred embodiment of the present invention is shown. In the following embodiments of the present invention, the portable electronic device is described as an example of a mobile phone, but is not limited thereto. The portable electronic device may also be another electronic device having a communication function. The mobile phone disclosed in the embodiment of the present invention is a mobile phone using a touch panel. In step S11G, the mobile phone is in a call state. If the mobile phone is in a call state, in the step of making a towel, it is determined whether one of the touch panels of the mobile phone is touched. Referring to Figure 2, there is shown a schematic diagram of an example of a touch panel in accordance with a preferred embodiment of the present invention. When the mobile phone is in a call state, if the touch panel 200 is touched, the user may want to use the touch panel to trigger some functions, such as touching the area 210, or the user's face may be accidentally gone. Touch the touch panel, for example, the touch area 22〇. Therefore, if the touch panel is touched, in step s13, it is determined whether the area touched by the 201019695 I-control panel is larger than a predetermined area. Usually, the user uses a finger or a stylus to touch the touch panel to trigger certain functions, and the area where the finger or the stylus touches the touch panel is farther than the user's face and the touch panel. The area is small, for example, the touch area 210 is smaller than the touch area 220. Therefore, if the touched area on the touch panel is larger than the predetermined area, that is, the user's face is inadvertently touched by the touch panel, the touch panel does not trigger the corresponding function in step S140. Make the phone still in a call. In this way, the mobile phone will not malfunction due to the accidental touch of the ® user. If the area touched on the touch panel is smaller than the predetermined area, it is determined that the user uses the touch panel to trigger certain functions by using a finger or a stylus. Therefore, in step S150, the mobile phone pauses the call state. The touch panel triggers the corresponding function. In addition, since the touch panel technology of the present invention includes a multi-touch panel, in step S130, it is determined whether the area covered by the plurality of adjacent touched points on the touch panel is larger than the predetermined area. For the criterion of the W coverage area, it can be determined whether the maximum spacing of the adjacent plurality of touched points is greater than a predetermined distance, so as to easily determine whether the area covered by the adjacent plurality of touched points is greater than a predetermined one. Area, improve the speed of cell phone judgment. Referring to Figure 3, there is shown a schematic diagram of an example of a touch area in accordance with a preferred embodiment of the present invention. The touch area 220 includes a plurality of adjacent touched points, wherein the points A and B have, for example, a maximum spacing d, and if the maximum spacing d is greater than a predetermined distance L, it is determined that the area of the touch area 220 is larger than a predetermined area. 201019695 In addition, multiple touch points that are not adjacent to a certain distance can be regarded as multi-touch, and the touch panel triggers the corresponding function. The method for avoiding the malfunction caused by the above-mentioned embodiments of the present invention is to determine whether the area touched on the touch panel is greater than a predetermined area when the portable electronic device is in a call state, thereby determining that the touch is correctly determined. Whether the control panel is touched by the user's face, so as to avoid malfunction of the portable electronic device and improve the convenience of use of the portable electronic device. In conclusion, the present invention has been described in terms of a preferred embodiment, and is not intended to limit the invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
