<p>The present invention discloses a touch screen device and a method for implementing proximity sensing by the touch screen device. The method includes: within a time interval of scanning sensing channels of a capacitive touch screen one by one, performing whole layer scanning for the sensing channels of the capacitive touch screen; and comparing a result of performing the whole layer scanning for the sensing channels of the capacitive touch screen with a preset threshold, and if the result of the whole layer scanning is larger than the preset threshold, triggering a corresponding processing of a large-area touch event. The present invention can implement the proximity sensing to a large-area object by the touch screen, and can distinguish effectively the large-area proximity event from the normal single-point or multi-point touch event during a user operation, thereby avoiding unnecessary false triggering; furthermore, the present invention integrates the proximity sensing function into the touch screen, which replaces the standalone proximity sensor in the terminal device, thereby saving the structural space of the terminal device and reducing the overall cost of the terminal device.</p> |
