Abstract:
1. A touch display device comprising: a display panel to display an image on a screen, the display panel including scan lines and data lines; and a driver configured to provide a display, on the screen, of a touch position based on a frame that includes a touch subfield, wherein the driver to provide at least one scan synchronization signal to the scan lines during the frame that includes the touch subfield, and the driver to provide at least one data synchronization signal to the data lines during the frame that includes the touch subfield, wherein the scan synchronization signal includes a first scan synchronization signal, a second scan synchronization signal, and a third scan synchronization signal, wherein the data synchronization signal includes a first data synchronization signal corresponding to the first scan synchronization signal, a second data synchronization signal corresponding to the second scan synchronization signal, and a third data synchronization signal corresponding to the third scan synchronization signal, wherein a first difference between a supply time point of the first data synchronization signal and a supply time point of the second data synchronization signal is different from a second difference between the supply time point of the second data synchronization signal and a supply time point of the third data synchronization signal, wherein a third difference between a supply time point of the first scan synchronization signal and a supply time point of the second scan synchronization signal is different from a fourth difference between the supply time point of the second scan synchronization signal and a supply time point of the third scan synchronization signal.
