Abstract: The invention provides a handheld device comprising an electronic paper, a control module and a touch module. When the handheld device is under a first input mode, the control module controls the electronic paper to show a first input image. Additionally, when the handheld device is under a second input mode, the control module controls the electronic paper to show a second input image. The touch module positioned beneath the electronic paper is used to sense a touch pressure acted on the electronic paper, so as to generate an input signal to manipulate the handheld device.

Abstract: The invention provides a wireless charging method. In the wireless charging method, when a handheld device enters a presupposed range, an identification code is wirelessly received from the handheld device. Afterward, whether the identification code is a presupposed identification code is judged. If the result of judgment is yes, then the handheld device is wirelessly charged. Once the handheld device leaves the presupposed range, the charging of the handheld device will be stopped.
