    Abstract: A display apparatus which determines a screen to be displayed when a power-on command is input, and method thereof, is provided. The display apparatus includes a display configured to display a content; an input unit configured to receive a command; and a controller configured to: in response to a power-off command being input while a content is displayed, determine whether or not the displayed content is appropriate to be subsequently displayed when a power-on command is input; in response to determining that the displayed content is not appropriate to be subsequently displayed when the power-on command is input, store a predetermined initial screen; in response to determining that the displayed content is appropriate to be subsequently displayed when a power-on command is input, store the displayed content; and in response to a power-on command being input, control the display to display the predetermined initial screen or the displayed content.

    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.

    Abstract: A gate driver (24) which is provided by an IGZO-GDM and a level shifter circuit (13) are connected to each other via a first through a fifth wires (OL1 through OL5). Each wire (OL) is connected to a discharge unit (190). If an electric power supply to a first through a fifth output circuits (OC1 through OC5) in the level shifter circuit (13) becomes lower than a lower operation limit value during a power-off sequence which is supposed to remove a residual charge from inside a panel, outputs from the first through the fifth output circuits (OC1 through OC5) assume a high-impedance state, whereupon a potential on each wire (OL) is drawn by a discharge unit (190) into a ground potential. Therefore, residual charge inside the panel is removed quickly and stably when power supply is shut off.
