Abstract
A display device is provided. The display device includes a liquid crystal display (LCD) panel for displaying images, a first electrode layer, and a second electrode layer coupled to the first electrode layer. The display device also includes a first driving circuit configured to provide a first driving signal and a second driving circuit configured to provide a second driving signal. Further, the display device includes a coupling unit coupled to the first driving circuit and the second driving circuit and configured to couple the first driving signal and the second driving signal, and to provide the coupled signal of the first driving signal and second driving signal to both of the first electrode layer and the second electrode layer such that the first driving signal drives the LCD panel for displaying the images, and the second driving signal drives the LCD panel for being touch-sensitive. The display device also includes a signal separation unit coupled to at least one of the first electrode layer and the second electrode layer to receive a feedback signal indicating a capacitance change corresponding to a touch on the LCD panel.
