Abstract: 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.
