Abstract

A touch display device including a touch panel, a display device, a plurality of first connecting terminals, and a plurality of second connecting terminals is provided. The display device is opposite to the touch panel. The first connecting terminals are disposed on the touch panel. The second connecting terminals are disposed on the display device, wherein the second connecting terminals are physically connected to the first connecting terminals such that the display device and the touch panel are electrically connected. A method for launching the touch panel of the touch display device is also provided.

Claims
