The present invention relates to a mobile terminal capable of a new type of user input, comprising: a backside input unit including a plurality of buttons and exposed to the backside of the mobile terminal; a memory for storing relationships between combinations of the plurality of buttons and control instructions of the mobile terminal and biometric information; a sensor unit, arranged on the backside of the mobile terminal and adjacent to the backside input unit, for sensing a user's bio signal; and a control unit for, upon receiving a user input in accordance with a particular combination of the plurality of buttons, controlling the sensor unit to sense the user's bio signal, and authenticating the user using the sensed bio signal and the stored biometric information.

Mobile terminal and method for controlling same

A touch display device may include an organic light emitting diode (OLED) display panel that includes scan lines, data lines, and OLED cells, and a driver to display a touch position on a screen (of the OLED display panel) in a frame that includes a touch subfield. The driver may supply at least one scan sync signal to the scan lines and supply at least one data sync signal to the data lines during one frame. The touch subfield may include a vertical touch subfield to detect a vertical position of the touch position and a horizontal touch subfield to detect a horizontal position of the touch position.

Touch display device having a driver to provide a scan synchronization signal and a data synchronization signal

A touch panel includes: a substrate; a plurality of light emitting elements; and a plurality of light receiving elements, wherein the number of light receiving elements may be greater than the number of light emitting elements.

Touch panel, method for driving touch panel, and display apparatus having touch panel

There are provided an image display apparatus having a display unit capable of sensing a touch made by a pointing device, and a method for operating the same. The method includes outputting a synchronous signal through the entire region of the display unit, transmitting a first scanning signal and a second scanning signal respectively scanning the display unit in a first direction and a second direction to the pointing device; and acquiring touch position information regarding a touch made by the pointing device by using touch time information regarding time points when the pointing device receives the first scanning signal and the second scanning signal after sensing the synchronous signal. Accordingly, an error in touch recognition caused by the delay of a synchronous signal can be minimized.
