However, when 婪9, it often causes the right-hand communication device to have a touch-screen screen, such as a touch of a cheek, and a cheek touches the touch screen, and the wrong #control's weight can cause the phone to be disconnected. , this touch ': two-way touch screen touch lock and perform any action. :;: The screen still shows information 'but can't be used to cause the user's _ though, single and effective, but when encountering two operating communication devices, such as "". One is when the user needs to call or send a file to the other party during the call, etc. 5 200838266 Second, the user does not put the communication device to the side of the ear to talk, but uses Bluetooth or an external wired headset to talk. In both cases, the touch screen does not need to be locked because the user's cheek does not accidentally touch the touch screen and causes an erroneous operation. However, if the communication device is locked by the touch screen described above during the call. In this way, the touch screen will also be locked in both cases, causing user confusion. SUMMARY OF THE INVENTION The object of the present invention is to provide a touch screen locking method and a communication device, wherein a light sensing module is disposed on a communication device to measure the amount of light entering, and the light amount is known to be used. Whether or not the communication device is placed next to the ear determines whether the touch screen is locked. The invention provides a touch screen locking method, which is applied to a communication device, and the communication device has at least a light sensing module and a touch screen module. The locking method includes voice communication by the communication device; receiving the amount of light by the light-sensing module; and calculating the amount of light entering according to the amount of light entering, • determining that the touch screen module switches to the normal mode or the screen locking mode. The invention further provides a communication device, which comprises a central processing module, a light sensing module and a touch screen module. The central processing module receives the dialing signal so that the communication device initiates a voice communication based on the dialing signal. The light sensing module receives the amount of light and generates a sensing signal corresponding to the amount of light entering, and the central processing module performs the calculation of the amount of light according to the sensing signal and obtains a calculation signal. The above-mentioned touch screen module switches to a normal mode or a screen lock mode according to the dial signal and the calculation signal. 6 200838266 The present invention is characterized in that a light sensing module is arranged on the communication device, which can receive the amount of light entering. Therefore, when the communication device performs voice communication, it can determine whether the user places the communication device according to the amount of light entering. Make a call next to your ear to determine whether to lock the touch screen module. [Embodiment] Hereinafter, a method and a communication device for locking a touch screen according to a preferred embodiment of the present invention will be described with reference to the related drawings. Referring to FIG. 1, a method for locking a touch screen according to a preferred embodiment of the present invention is shown. In this embodiment, the locking method is applied to a communication device having a touch screen module, and the communication device further has a light sensing module. In addition, the communication device has a casing, and the touch-type glory module and the light sensing module are exposed on the same side of the casing. First, in step S01, the locking method of the embodiment performs a voice communication by means of the communication device, that is, the communication device is in the telephone connection. Next, the state of the call connection is continuously maintained (step S02), and an amount of incoming light is received by the light sensing module (step S03). Here, the light sensing module has a light sensing element, and the light sensing element may be, for example, a photodiode or a phototransistor, but is not limited thereto. In general, when a user is using a communication device to make a call, it is customary to place the communication device in the ear in order to listen to the other party's voice message and speak. In this case, and since the light sensing module and the touch screen module of the embodiment are exposed on the same side of the housing, the light sensing module 7 200838266 will directly receive the cheek in the light direction. Or the block of the ear, so that the amount of incoming light will be less than a normal amount of light. Here, the normal amount of light entering refers to the amount of light entering the light sensing module in a general case, that is, when there is no obstruction in the light entering direction. Then, step S04 to step S06 are performed, and a light amount calculation is performed according to the amount of light entering to determine whether the touch screen module is switched to a normal mode or a screen lock mode. In this embodiment, the normal mode refers to a touch screen module having functions such as a screen display, a touch operation, and the like. The screen lock mode means that the touch screen module is locked, that is, it cannot be operated by tapping, but functions such as screen display can still be performed. In this embodiment, the light amount calculation system compares the amount of light entering with a preset value, and when the amount of light entering is lower than the preset value, the touch screen module switches to the screen lock mode. When the user places the communication device beside the ear and communicates, the light sensing module is blocked by the cheek or the ear, so that the amount of light entering is less than a normal amount of light, and by comparing the amount of light entering with a preset value, The preset value may be, for example, ten percent of the normal amount of light entering (step S04), and the * touch-type honor screen module is switched to the honor screen lock mode to lock the touch-type honor screen module 10 (step S05) ), thereby preventing the user from accidentally touching the touch screen module and causing improper operations, such as interrupting communication and the like. Of course, in this embodiment, the user can dynamically set the preset value to meet the needs of each user. In addition, when the user is communicating, it may happen that the communication device is not placed next to the ear, but is placed in another place, for example, when the user needs to operate the communication device during the call to inquire the phone or transmit the text 8 200838266 When the user is talking on a Bluetooth or an external wired headset, these situations do not require the communication device to be placed next to the ear. At this time, since the light entering direction of the light sensing module is not blocked, the amount of light entering may be greater than a preset value. In this case, the touch screen module is switched to the normal mode (step S06). To facilitate the user to touch the operation. Finally, when the communication ends, the locking method of the present embodiment also ends. Referring to FIG. 2, it is a schematic diagram of a communication device 1 according to a preferred embodiment of the present invention. The communication device 1 has a touch screen module φ 11 , a light sensing module 12 and a housing 13 , and the light sensing module 12 and the touch screen module 11 are exposed on the same side of the housing 13 . Referring again to FIG. 3, it is a block diagram of the communication device 1 of the present embodiment. The communication device 1 further includes a central processing module 14. In this embodiment, the central processing module 14 is electrically connected to the light sensing module 12 and the touch control screen module 11, respectively. When the user wants to perform voice communication, the central processing module 14 receives a dialing signal CS, so that the communication device 1 initiates voice communication according to the dialing signal CS. In this case, the dialing CS can be output to the central processing module 14 by the user pressing a button, touching the touch screen module 11 or by voice operation. In the voice communication, the light sensing module 12 receives an incoming light amount LA and generates a sensing signal SS corresponding to the incoming light amount LA. Here, the sensing signal SS is transmitted to the central processing module 14. The central processing module 14 performs an incoming light amount calculation based on the sensing signal SS and obtains an arithmetic signal. Then, the touch screen module 11 switches to a normal mode or a screen lock mode according to the dial signal CS and the calculation signal. Among them, the judgment of the switching mode 9 200838266 method has been described above in the above-mentioned locking manner, in summary, when the details are entered in the #旦κ instance, so it is no longer 赘π switched to the glory ^ to the preset value The touch screen module group η is improperly generated ^ Avoiding the user accidentally touching the touch screen mode η switch: When the amount of light entering is greater than the preset value, the touch is further, when the user ends t: Pass: Touch operation ' will receive a closing signal.夂== When the module 14 ES is used, the touch-type processing module and the group 14 receive the end-of-user to perform the point (4) discrimination (10) to the money ^ for the above description, the present invention The locking method and the communication device are equipped with a light sensing module that can receive the amount of light, so:: When performing voice communication, it can be based on the amount of light entering. Call next to it, ί = 疋疋 No lock the touch screen module. Further, the foregoing is merely illustrative and not limiting. The spirit of the invention and the equivalent modifications thereto shall be included in the scope of the appended patent application.
