Structure and method to provide support for flexible display
Described herein are a structure and method for to provide support for a flexible display of an information handling system. Several layers of the flexible display are stacked with a metal foil. The metal foil provides support and bending as defined by design requirements of the flexible display. Particular areas of the metal foil have specific thickness and/or density based on the design requirements. The bending area is allowed to be bent or folded over with thickness and/or density to allow such.
1 . A support structure for a flexible display of an information handling system comprising:
multiple layers included in the flexible display;
a metal foil stacked up with the multiple layers, wherein the metal foil comprises:
a bending area as defined by design requirements of the flexible display; and
other areas as defined the design requirements, wherein the bending area and other areas have particular thicknesses and/or densities based on the design requirements, wherein the design requirements provide for oblique micro structures on the metal foil.
2 . The support structure claim 1 , wherein the multiple layers include a glass/plastic layer, an OLED layer, a TFT layer, and a substrate layer.
3 . The support structure claim 1 , wherein the metal foil is comprised of stainless steel, titanium, aluminum, or other bendable material.
4 . The support structure of claim 1 , wherein the micro structures are developed on the metal foil for dual side, depth, and partial openings.
5 . The support structure of claim 1 , wherein the bending area has varying thickness and/or density based on curvature.
6 . The support structure of claim 1 , wherein the various layers and metal foil are fully enclosed when folded.
7 . An information handling system comprising:
a flexible display that comprises:
multiple layers;
a metal foil stacked up with the multiple layers, wherein the metal foil comprises:
a bending area as defined by design requirements of the flexible display; and
other areas as defined the design requirements, wherein the bending area and other areas have particular thicknesses and/or densities based on the design requirements, wherein the design requirements provide for oblique micro structures on the metal foil.
8 . The information handling system of claim 7 , wherein the multiple layers include a glass/plastic layer, an OLED layer, a TFT layer, and a substrate layer.
9 . The information handling system of claim 7 , wherein the metal foil is comprised of stainless steel, titanium, aluminum, or other bendable material.
10 . The information handling system of claim 7 , wherein the micro structures are developed on the metal foil for dual side, depth, and partial openings.
11 . The information handling system of claim 7 , wherein the bending area has varying thickness and/or density based on curvature.
12 . The information handling system of claim 7 , wherein the various layers and metal foil are fully enclosed when folded.
13 . A method for providing support and bending of flexible displays of information handling systems comprising:
determining design requirements are determined for the flexible display, wherein the design requirements provide for oblique micro structures on the metal foil;
determining bending area of the flexible display;
forming thickness and/or density at particular areas of a metal foil based on the design requirements;
attaching the metal foil to the various layers of the flexible display in a stacked order.
14 . The method of claim 13 , wherein the micro structures are etched or stenciled into the metal foil.
15 . The method of claim 13 , wherein the micro structures are shaped as oblique structures to provide deposition uniformity and pixel density of the flexible display.
16 . The method of claim 13 , wherein the bending area includes different degrees of curvature or bending.
