Abstract

Claims (29)

1. A display for an information handling system, the display comprising:

a display panel cell;

a mold frame; and

a chip-on-film coupled to the display panel cell,

wherein the chip-on-film comprises one or more protrusions in contact with the mold frame,

wherein the one or more protrusions comprise a plurality of imprinted embossed impressions, and

wherein the one or more protrusions comprise less than one percent of a surface area of the chip-on-film, wherein a first portion of the chip-on-film is adjacent to the one or more protrusions across a width of a first surface of the chip-on-film, and wherein the first portion of the chip-on-film adjacent to the one or more protrusions is not in contact with the mold frame.

2. The display of claim 1 , wherein the plurality of imprinted embossed impressions comprise convex imprinted embossed impressions, and wherein an apex of one or more of the convex imprinted embossed impressions is in contact with the mold frame.

3. The display of claim 1 , wherein the plurality of imprinted embossed impressions is asymmetrical.

4. The display of claim 1 , wherein the chip-on-film further comprises a plurality of traces, and wherein the plurality of traces are positioned to avoid distortion of one or more of the plurality of traces by the one or more protrusions.

5. The display of claim 1 , further comprising:

a display printed circuit board (PCB),

wherein the chip-on-film is further coupled to the display PCB.

6. The display of claim 1 , further comprising:

a decorative casing,

wherein at least part of a first surface of the chip-on-film is in contact with the decorative casing.

7. The display of claim 1 , wherein the one or more protrusions are positioned to allow particles to move freely between the chip-on-film and the mold frame.

8. A chip-on-film for a display, the chip-on-film comprising:

a first connector for coupling to a display panel cell;

a second connector for coupling to a display printed circuit board (PCB); and

one or more protrusions in contact with a mold frame of the display,

wherein a first portion of the chip-on-film is adjacent to the one or more protrusions across a width of a first surface of the chip-on-film,

wherein the one or more protrusions are in contact with a mold frame and the first portion of the chip-on-film adjacent to the one or more protrusions is not in contact with the mold frame,

wherein the one or more protrusions comprise a plurality of imprinted embossed impressions, and

wherein the one or more protrusions comprise less than one percent of a surface area of the chip-on-film, wherein a first portion of the chip-on-film is adjacent to the one or more protrusions across a width of a first surface of the chip-on-film, and wherein the first portion of the chip-on-film adjacent to the one or more protrusions is not in contact with the mold frame.

9. The chip-on-film of claim 8 , wherein the plurality of imprinted embossed impressions comprise convex imprinted embossed impressions, and wherein an apex of one or more of the convex imprinted embossed impressions is in contact with the mold frame.

10. The chip-on-film of claim 8 , wherein the plurality of imprinted embossed impressions is asymmetrical.

11. The chip-on-film of claim 8 , wherein the chip-on-film further comprises a plurality of traces, and wherein the plurality of traces are positioned to avoid distortion of one or more of the plurality of traces by the one or more protrusions.

12. The chip-on-film of claim 8 , wherein at least part of a surface of the chip-on-film is in contact with a decorative casing.
