Touch display device

摘要

A touch display device includes a first substrate, a second substrate opposite to the first substrate, a display medium sandwiched between the two substrates, and a touch-sensitive layer including sensitive electrode lines. The first substrate includes a first surface facing the display medium layer and a second surface far away from the display medium layer and opposite to the first surface. The touch-sensitive layer is disposed on the second surface of the first substrate, and first pins are disposed on a side area of the first substrate corresponding to a side of the touch display device to connect the sensitive electrode lines. Second pins are disposed on a side area of the second substrate corresponding to the same side of the touch display device, and connected to the first pins via a first printed circuit board (PCB). The first PCB is a flexible PCB.
