Handheld equipment and method for preventing touch screen from spurious triggering in call process of handheld equipment

Abstract

The invention discloses and a method for preventing a touch screen from spurious triggering in a call process of handheld equipment. The method comprises the following steps of: detecting a call state of the handheld equipment; when the handheld equipment is opened to call, adjusting a sensitivity of a touch screen to be an approximate sensing sensitivity from a direct contact sensitivity, wherein the approximate sensing sensitivity is greater than the direct contact sensitivity; detecting a capacitance value of the touch screen and comparing a capacitance variation value with the approximate sensing sensitivity to obtain random pattern parameters corresponding to a touch region; comparing the random pattern parameters with pre-set parameters and locking the touch screen according to comparing results. The invention further discloses the handheld equipment. According to the invention, the method provided by the invention can be used for effectively avoiding the on-hook caused by the spurious triggering in the call process so that the design difficulty and cost of the handheld equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of touch screen terminals, in particular to a handheld device and a method for preventing false triggering of a touch screen during a call. Background technique [0002] In recent years, touch screens have been widely used in mobile communication terminals and portable computers. Users can complete all the functions of ordinary keyboards by performing operations such as clicking and swiping on the touch screens. Therefore, touch screens can make human-computer interaction more straightforward. [0003] However, during a call on the handheld device, the contact between the touch screen and the user's face or head is likely to cause misoperation and cause the call to be interrupted. The usual solution is to use a proximity sensor on a handheld device with a touch function to prevent the user from accidentally hanging up when the face is in contact with the touch screen during a call. However, the use of a prox...

Problems solved by technology

In addition, the proximity sensor and infrared emission tube need to be placed near the earpiece. Due to the transmission of light, holes need to be opened on the shell of the handheld device. All of the above increase the design difficulty of the appearance and structure of the handheld device, and also increase the production cost.
