Problems solved by technology

In this way, as the number of touch screens increases, the electronic device will inevitably consume more hardware space to set the same number of screen control circuits
Relatively, the central processing unit must also consume more pins and more complex instructions to control multiple screen control circuits at the same time

Abstract

The invention provides a handheld electronic device and an operation method thereof. The handheld electronic device comprises a plurality of touch screens and a screen control circuit, wherein each touch screen judges whether to generate a touch signal or not according to the pressed state of the touch screen; the screen control circuit combines the touch points of the touch screens into a point set and defines the touch points of the touch screens according to a reference point; in addition, the screen control circuit converts the touch signal into a coordinate value under the point set according to the reference point, so that the handheld electronic device performs corresponding operation according to the coordinate value.

Description

technical field [0001] The present invention relates to a handheld electronic device and its operating method, in particular to a handheld electronic device with multiple touch screens and its operating method. Background technique [0002] With the rapid development of technology, manufacturers of handheld electronic products such as notebook computers, mobile phones, and multimedia players all have a tendency to use touch screens to replace traditional keyboards as a new generation of input interfaces. In addition, with the continuous advancement of electronic technology, handheld electronic products with dual touch screens have recently been launched on the market. Taking a mobile phone as an example, the flip-type or slider-type mobile phones on the market recently are equipped with corresponding touch screens on the upper and lower bodies respectively. Thus, no matter whether the upper and lower bodies are unfolded or not, the user can control the mobile phone through ...
