Document Type and Number:
Japanese Patent JP6554560
Kind Code:
B2
Abstract:
The present invention relates to a method and a device for displaying time on a mobile device. The method includes: determining whether a preset operation for displaying device time is detected when a screen of the mobile device is off; when determining that the preset operation for displaying the device time is detected, sending device time computed by a touch chip to a display driver chip through the touch chip, in which the touch chip is configured to acquire standard time when an application processor is closed and to compute the device time according to an internal clock; and switching on the screen and displaying the device time on the screen through the display driver chip. With technical solutions of the present invention, it is not required to wake up the application processor when a user views time, so as to avoid power consumption resulted from waking up the application processor to compute time. As a result, the power consumption is greatly reduced when the user views time and battery life of the mobile device is prolonged.
