Title: METHOD FOR PROCESSING DATA COLLECTED BY TOUCH PANEL, AND TERMINAL DEVICE
Abstract:
Disclosed are a method for processing data collected by a touch panel, and a terminal device. Power consumption of the device can be reduced. In embodiments of the present invention, the touch panel communicates with an application processor (AP) by constructing a dedicated channel by means of an MCU, instead of directly communicating with the AP. The method in the embodiments of the present invention comprises: an MCU acquires touch data from a touch panel, preprocesses the touch data, and sends the preprocessed touch data to an AP. Since an MCU preprocesses touch data of a touch panel to filter out invalid touch data and then sends valid touch data to an AP, the MCU not only can process the touch data of the touch panel at any time when the AP is in a sleep state, but also can filter the touch data, so as to prevent the AP in the sleep state from being waken up by invalid touch events, thereby reducing load of the AP and power consumption of the device.
