DISPLAY PANEL GROUNDING
A display device improves the grounding connection of a polarizer by using a metal bridge that couples the polarizer to a ground of the display device. The display device includes a backlight unit (BLU) for providing light for displaying an image, a plurality of pixels for modulating the light provided by the BLU, a polarizer for filtering the light provided by the BLU, and the metal bridge. The metal bridge is disposed in a non-display area surrounding a display area of the display device.
1 . A display device comprising:
a backlight unit (BLU) for providing light for displaying an image;
a plurality of pixels for modulating the light provided by the BLU, the plurality of pixels disposed in a display area of the display device;
a polarizer configured to filter the light provided by the BLU based on the modulation performed by the plurality of pixels; and
a metal bridge coupled to the polarizer, the metal bridge disposed in a non-display area surrounding the display area of the display device, wherein the metal bridge does not overlap with the display area of the display device.
2 . The display device of claim 1 , further comprising:
a color filter, wherein the metal bridge is disposed between the color filter and the polarizer.
3 . The display device of claim 2 , wherein a first surface of the metal bridge is adhered to a first portion of the color filter, wherein a second surface of the metal bridge, opposite to the first surface, is adhered to a first portion of the polarizer, and wherein a second portion of the polarizer is adhered to a second portion of the color filter.
4 . The display device of claim 1 , further comprising:
a connector coupled to the metal bridge, the connector for connecting the metal bridge to a ground of the display device.
5 . The display device of claim 4 , wherein the connector is a silver (Ag) dot connector.
6 . The display device of claim 1 , wherein the metal bridge comprises:
a first triangular section corresponding to a first corner of the polarizer.
7 . The display device of claim 6 , wherein the metal bridge further comprises:
a second triangular section corresponding to a second corner of the polarizer; and
a connecting strip connecting the first triangular section to the second triangular section.
8 . The display device of claim 6 , wherein the metal bridge further comprises:
a first extension strip extending from a first corner of the first triangle in a first direction; and
a second extension strip extending from a second corner of the first triangle in a second direction, perpendicular to the first direction.
9 . The display device of claim 1 , further comprising:
an optically clear adhesive (OCA) disposed over the polarizer, the OCA for adhering the polarizer to the metal bridge.
10 . The display device of claim 9 , wherein the OCA is electrically conductive.
11 . The display device of claim 1 , wherein the metal bridge if made of a non-transparent material.
12 . The display device of claim 1 , wherein the metal bridge if patterned so as to not cover the display area of the display device.
13 . A color filter for a display device, comprising:
a color filter glass having a display area and a non-display area surrounding the display area; and
a metal bridge disposed on the non-display area of the color filter glass, wherein the metal bridge does not overlap with the display area of the color filter glass.
14 . The color filter glass of claim 13 , wherein the metal bridge comprises
a first triangular section corresponding to a first corner of the color filter glass.
15 . The color filter glass of claim 14 , wherein the metal bridge further comprises:
a second triangular section corresponding to a second corner of the color filter glass; and
a connecting strip connecting the first triangular section to the second triangular section.
16 . The color filter glass of claim 13 , wherein the metal bridge further comprises:
a first extension strip extending from a first corner of the first triangle in a first direction; and
a second extension strip extending from a second corner of the first triangle in a second direction, perpendicular to the first direction.
17 . The color filter glass of claim 13 , further comprising:
a connector coupled to the metal bridge, the connector for connecting the metal bridge to a ground of the display device.
18 . The color filter glass of claim 17 , wherein the connector is a silver (Ag) dot connector.
19 . The color filter glass of claim 13 , wherein the metal bridge if made of a non-transparent material.
20 . A head-mounted display comprising:
A display device comprising:
a backlight unit (BLU) for providing light for displaying an image;
a plurality of pixels for modulating the light provided by the BLU, the plurality of pixels disposed in a display area of the display device;
a polarizer configured to filter the light provided by the BLU based on the modulation performed by the plurality of pixels; and
a metal bridge coupled to the polarizer, the metal bridge disposed in a non-display area surrounding the display area of the display device, wherein the metal bridge does not overlap with the display area of the display device.
