    摘要: 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.

    摘要: 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.
