技术领域technical field
本发明涉及移动通信领域，更具体地说，涉及一种可防止通话时误操作的触摸屏手机及其使用方法。The invention relates to the field of mobile communication, and more specifically relates to a touch-screen mobile phone capable of preventing misoperation during a call and a use method thereof.
背景技术Background technique
目前带触摸屏的手机大部分采用的是电容触摸屏，这给用户带来了全新的体验，但也出现了很多不可避免的问题。比如，在通话时经常会出现脸部、手部或头发触碰到触摸屏的情况，对于电容式触摸屏，这类触碰动作容易导致对手机进行误操作，而影响正常使用。目前解决这一问题的主要采取的方法是：为手机配备红外检测装置以检测脸部与触摸屏的距离，通话时如果红外检测到人脸靠近屏幕到了一定距离，就自动关闭触摸屏防止可能发生的误操作。At present, most of the mobile phones with touch screens use capacitive touch screens, which brings a new experience to users, but there are also many unavoidable problems. For example, the face, hands or hair often touch the touch screen during a call. For a capacitive touch screen, such touch actions can easily lead to misoperation of the mobile phone and affect normal use. At present, the main method to solve this problem is: equip the mobile phone with an infrared detection device to detect the distance between the face and the touch screen. If the infrared detection detects that the face is close to the screen to a certain distance during the call, the touch screen will be automatically turned off to prevent possible errors. operate.
然而在上述方法中，手机中的红外线检测装置一般是靠红外发射LED灯发射红外线，在红外线被外界物体反射回来时，通过反射回来的红外线强度判断外界物体与触摸屏的距离。但在通话过程中，触摸屏如果较为贴近头发，则用于测距的红外线可能会被头发吸收而无法正常反射回来，可能造成距离误判，从而仍然可能导致误操作。However, in the above method, the infrared detection device in the mobile phone generally emits infrared rays by an infrared emitting LED lamp. When the infrared rays are reflected back by an external object, the distance between the external object and the touch screen is judged by the intensity of the reflected infrared rays. However, during a call, if the touch screen is close to the hair, the infrared rays used for distance measurement may be absorbed by the hair and cannot be reflected back normally, which may cause misjudgment of the distance, which may still lead to misoperation.

具体实施方式Detailed ways
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
在触摸屏手机中红外线LED灯、光感器和接近感应器一般整合于同一芯片中，其中红外线LED灯发射红外线，接近感应器靠测量外界物体反射回来的红外线强度判断与触摸屏的距离。但在通话过程中，如果触摸屏贴近头发的话，红外线会被头发吸收，造成接近感应器对距离的误判，进而导致错误操作。但是接触头发也可能会对触摸屏产生误操作，且由于打开了触摸屏增加了手机的功耗。当触摸屏手机接近头发时，光感器检测到外界的光强度值将几乎为0。利用上述原理，可以使用光感器和接近感应器相结合来对触摸屏进行控制，能有效避免因接触头发对触摸屏产生的误操作，并避免此种情况下因开启触摸屏而产生的功耗。In the touch screen mobile phone, the infrared LED light, light sensor and proximity sensor are generally integrated in the same chip. The infrared LED light emits infrared rays, and the proximity sensor judges the distance from the touch screen by measuring the intensity of infrared rays reflected from external objects. However, during a call, if the touch screen is close to the hair, the infrared rays will be absorbed by the hair, causing the proximity sensor to misjudge the distance, which in turn leads to wrong operations. However, touching the hair may also cause misoperation of the touch screen, and the power consumption of the mobile phone is increased due to the opening of the touch screen. When the touch screen mobile phone is close to the hair, the light sensor detects that the light intensity value of the outside world will be almost 0. Utilizing the above principles, the combination of light sensor and proximity sensor can be used to control the touch screen, which can effectively avoid the misoperation of the touch screen caused by touching the hair, and avoid the power consumption caused by turning on the touch screen in this case.
如图1所示为本发明一较佳实施例的防止触摸屏手机通话时误操作的方法流程图，所述触摸屏手机包括：接近感应器、光感器，所述方法包括以下步骤：As shown in Figure 1, it is a flow chart of a method for preventing misoperation of a touch-screen mobile phone during a call according to a preferred embodiment of the present invention. The touch-screen mobile phone includes: a proximity sensor and a light sensor, and the method includes the following steps:
100、在通话过程中，即时地利用所述接近感应器测量外界物体与该触摸屏手机的距离；100. During a call, use the proximity sensor to measure the distance between an external object and the touch-screen mobile phone in real time;
101、若外界物体与该触摸屏手机的距离大于一设定的第一距离阈值，则通过光感器获取外界的光强度值；101. If the distance between the external object and the touch-screen mobile phone is greater than a set first distance threshold, obtain the external light intensity value through the light sensor;
102、若所述外界的光强度值小于一设定的光强度阈值，且外界物体与该触摸屏手机的距离同时小于一设定的第二距离阈值，则关闭所述触摸屏。102. If the light intensity value of the outside world is less than a set light intensity threshold, and the distance between the external object and the touch-screen mobile phone is also less than a set second distance threshold, turn off the touch screen.
步骤C中，若所述光强度值大于所述光强度阈值，则维持触摸屏的开启状态。In step C, if the light intensity value is greater than the light intensity threshold, the touch screen is maintained in an on state.
步骤C中，若所述光强度值小于所述光强度阈值，但外界物体与该触摸屏手机的距离大于所述第二距离阈值，则维持触摸屏的开启状态。In step C, if the light intensity value is less than the light intensity threshold, but the distance between the external object and the touch-screen mobile phone is greater than the second distance threshold, the touch screen is maintained in the on state.
所述关闭触摸屏包括以下操作：关闭该触摸屏手机的屏幕背光、显示屏和触摸屏检测装置。Said turning off the touch screen includes the following operations: turning off the screen backlight, display screen and touch screen detection device of the touch screen mobile phone.
所述第二距离阈值大于所述第一距离阈值。第一距离阈值和第二距离阀值是根据具体接近感应器芯片的性能进行设置的，例如可设置第一距离阈值为0.1cm，第二距离阈值为0.2cm。根据上述设置，当检测到触摸屏与脸部的距离d大于等于0.1cm时，并不马上打开触摸屏，而是首先检测光感器的光强度值是小于设定的光强度阈值，光强度阈值可设置为接近于0的值。如果小于设定的光强度阈值，则判断距离d是否大于或等于0.2cm，如果大于或等于0.2cm，则触摸屏保存开启状态，如果小于0.2cm则关闭触摸屏。如果距离d小于0.1cm则直接关闭触摸屏。The second distance threshold is greater than the first distance threshold. The first distance threshold and the second distance threshold are set according to the performance of the specific proximity sensor chip, for example, the first distance threshold can be set to 0.1 cm, and the second distance threshold can be set to 0.2 cm. According to the above settings, when it is detected that the distance d between the touch screen and the face is greater than or equal to 0.1cm, the touch screen will not be turned on immediately, but the light intensity value of the light sensor is first detected to be less than the set light intensity threshold, and the light intensity threshold can be set. Set to a value close to 0. If it is less than the set light intensity threshold, then judge whether the distance d is greater than or equal to 0.2cm, if greater than or equal to 0.2cm, the touch screen is kept on, and if it is less than 0.2cm, the touch screen is turned off. If the distance d is less than 0.1cm, the touch screen will be turned off directly.
