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

Embodiment Construction

[0027] 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.

[0028] In the touch screen mobile phone, the infrared LED light, light sensor and proximity sensor are generally integrated in the same chip, in which the infrared LED light emits infrared rays, and the proximity sensor judges the distance from the touch screen by measuring the infrared intensity reflected by 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 ...

Abstract

The invention discloses a touch screen cellphone capable of preventing misoperations during calls and a using method for the touch screen cellphone. The touch screen cellphone comprises a proximity sensor and an optical sensor, the method includes following steps: immediately utilizing the proximity sensor to measuring the distance between an external object and the touch screen cellphone during calls; obtaining optical intensity value outside through the optical sensor if the distance between the external object and the touch screen cellphone is larger than a set first distance threshold; and closing a touch screen if the optical intensity value outside is smaller than a set optical intensity threshold and the distance between the external object and the touch screen cellphone is smaller than a set second distance threshold simultaneously. The touch screen cellphone capable of preventing misoperations during calls and the using method for the touch screen cellphone have the advantages that when the proximity sensor judges that the cellphone is far away, the optical intensity value is read through the optical sensor, so that states of the cellphone can be judged more accurately, the screen of the cellphone can be guaranteed to be closed more accurately, misoperations can be prevented, and power consumption can be lowered.

Description

technical field [0001] 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. Background technique [0002] 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. ...
