Abstract
A touch display device including a pixel array substrate, an opposite substrate, and a display medium layer is provided. The pixel array substrate includes a first substrate and a plurality of sensing electrodes. The first substrate has a plurality of sub-pixel areas arranged in array. The sensing electrodes are disposed on the first substrate and electrically insulated to each other, wherein at least portion of the sensing electrodes cover a number of the sub-pixel areas, respectively. The opposite substrate is opposite to the pixel array substrate and includes a second substrate and a pressure sensing layer. The pressure sensing layer is disposed on a surface of the second substrate facing the pixel array substrate. The display medium layer is located between the sensing electrodes and the pressure sensing layer. A driving method and a pressure detection method of the touch display device are also provided.
