Abstract
Embodiments of a touch screen display device having improved electrostatic discharge (ESD) protection are provided herein with a touch screen and a display module underlying the touch screen. The touch screen described herein includes a touch panel substrate having a plurality of transmit lines, a plurality of receive lines, a plurality of routing traces and a ground ring formed thereon. The ground ring includes inner edges, which conform to and surround a periphery of the transmit lines, receive lines and routing traces, and outer edges that are substantially parallel and adjacent to edges of the touch panel substrate. At least one of the outer edges of the ground ring extend past at least one outer edge of the display module along at least one entire side of the display module, thereby providing ESD protection to the display module on all such sides.
