System and method for ESD protection in a touch screen display
System and methods for ESD protection in a touch screen display are disclosed. A touch screen display for an Information Handling System (IHS) include a coverglass, an ESD ground ring on the coverglass; and a touch panel proximate to the coverglass. An information handling system includes a display housing including a bezel adapted to retain a plurality of display components; the plurality of display components including a coverglass, an ESD ground ring on the coverglass; and a touch panel proximate to the coverglass. Methods are also disclosed.
1. A touch screen display for an Information Handling System (IHS), comprising:
a coverglass;
an ESD ground ring on the coverglass;
a touch panel proximate to the coverglass, the touch panel including a trace routing portion;
a protection layer proximate the touch panel and separate from the touch panel; and
a second ESD ground ring on the protection layer and separate from the touch panel;
wherein the ESD ground ring is positioned within an area of the coverglass that overlaps the trace routing portion and wherein the second ESD ground ring is positioned within a portion of the protection layer that overlaps the trace routing portion.
2. The touch screen display of claim 1 , wherein the touch panel is a metal mesh film-based sensor.
3. The touch screen display of claim 1 , further comprising:
a bezel surrounding and partially overlapping the coverglass;
wherein the, ESD ground ring is within the area of the coverglass that is overlapped by the bezel.
4. The touch screen display of claim 1 , wherein the ESD ground ring comprises silver ink.
5. An information handling system comprising:
a display housing including a bezel adapted to retain a plurality of display components; the plurality of display components including:
a coverglass;
an ESD ground ring on the coverglass;
a touch panel proximate to the coverglass, the touch panel including a trace routing portion;
a protection layer proximate to the touch panel and separate from the touch panel; and
a second ESD ground ring on the protection layer and separate from the touch panel;
wherein the ESD ground ring is positioned within an area of the coverglass that overlaps the trace routing portion and wherein the second ESD ground ring is positioned within a portion of the protection layer that overlaps the trace routing portion.
6. The information handling system of claim 5 , wherein the touch panel is a metal mesh film-based sensor.
7. The information handling system of claim 5 , wherein the ESD ground ring is within an area of the coverglass that is overlapped by the bezel.
8. The information handling system of claim 5 , wherein:
the touch panel includes a trace routing portion; and
wherein the ESD ground ring is within an area of the coverglass that overlaps the trace routing portion.
9. A method of manufacturing a touch panel display comprising:
depositing an ESD ground ring on a coverglass;
affixing the coverglass to a touch panel, the touch panel including a trace routing portion;
depositing a second ESD ground ring on a protection layer affixed to a display element, wherein the second ESD ground ring is separate from the touch panel; and
affixing the touch panel to the protection layer, wherein the protection layer is separate from the touch panel;
wherein the ESD ground ring is deposited within an area of the coverglass that overlaps the trace routing portion and wherein the second ESD ground ring is deposited within a portion of the protection layer that overlaps the trace routing portion.
10. The method of claim 9 , wherein the touch panel is a metal mesh film-based sensor.
11. The method of claim 9 , wherein the ESD ground ring comprises silver ink.
