DEVICE DRIVING SYSTEM THROUGH TOUCH INPUT IN LOW POWER MODE IN WHICH DISPLAY IS OFF

摘要

The present invention relates, in general, to a system and a method for quickly driving a device through a touch input in a low power mode in which a display of the device is off. More particularly, the present invention relates to a device driving system and a device driving method, which can minimize power consumption through only a predetermined touch input in a low power mode in which a display of a device is off, and quickly perform unlocking of the device, system control or execution of an application.

主权项

1. A device driving system through a touch input in a low power mode in which a display is off, the device driving system comprising:
a touch panel; a touch screen controller configured to sense a touch input on the touch panel and transmit/receive corresponding information; and an application processor configured to drive an application of a device, using the information transmitted from the touch screen controller, and set modes of the touch panel and the touch screen controller, wherein the application processor includes a low power mode setting module configured to convert the mode of the touch screen controller into the low power mode when there is no touch input for a certain period of time or when the device is off, and the touch screen controller includes a low power mode touch recognition unit configured to sense only a predetermined touch input in the low power mode, to sense only the predetermined touch input even in the low power mode in which the display is off, thereby quickly driving the device while minimizing power consumption.
