Abstract: A plug-in touch display device includes a capacitive touch screen stacked on a display module. The display module includes a display panel and a backlight module that are supported in a middle frame. The display panel includes an array substrate that includes a pixel electrode, which also serves as a first capacitive sensing electrode. The middle frame has one side facing the backlight module and receiving a second capacitive sensing electrode arranged therein. A gap exists between the second capacitive sensing electrode and backlight module. The first capacitive sensing electrode and the second capacitive sensing electrode configure an electrode-induction device jointly, for sensing a pressure signal applied on the capacitive touch screen. In a display time period of one frame, the pixel electrode transmits pixel voltage signals and pressure sensing signals alternately.
