The touch display includes a capacitive touch screen to sense a touch and a display module includes a display panel having conductive layers which one of the conductive layers is configured to be used as a first capacitive sensing electrode, a backlight module positioned oppositely to the display panel, and a middle frame, configured to support the display panel and the backlight module. A second capacitive sensing electrode is positioned at a side of the middle frame, which is toward the backlight module. A gap exists between the second capacitive sensing electrode and the backlight module. The first capacitive sensing electrode and the second capacitive sensing electrode forms a capacitive sensing structure for sensing a pressure applied on the capacitive touch panel. This structure is compact and easy to produce and thus reduces the manufacturing expenses.
