Abstract

An information handling system display with zero bezel defines a perimeter with a square side of a cover glass having a curved interior surface and a gradient refractive index portion that focuses visual images from a folded display film to a flat upper surface of the cover glass. The folded display film provides a display image across a full length of the cover glass while fitting under the cover glass with the fold and presenting undistorted visual images through the lens focus provided by the gradient refractive index portion.

First claim

What is claimed is:

1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to execute instructions that process information;
a memory interfaced with the processor and operable to store the instructions and information; and
a display integrated in the housing, the display having an organic light emitting diode (OLED) display film and a cover glass, the cover glass at opposing sides having a square outer corner integrating a gradient refractive index portion configured to refract light to a front face of the glass cover, the front face having a flat outer surface, the OLED display film having a flat central region with pixels of the OLED display film having planar disposition at a first distance from the flat outer surface and a curved region with pixels of the OLED display film having a curved disposition along at least a portion of a perimeter of the housing, the curved region increasing the distance of the pixels from the cover glass outer surface to a second distance at a perimeter of the OLED display film, the cover glass having a curved inner surface that conforms with the OLED display film pixels in the curved region.

2. The information handling system of claim 1 further comprising:
an upper frame disposed at a perimeter of an upper side of the display; and
a lower frame disposed at a lower perimeter of a lower side of the display;
wherein the opposing sides define the outer perimeter of the display and housing.

3. The information handling system of claim 1 wherein the organic light emitting diode film folds away from the glass cover outer surface at each of the opposing sides.

4. The information handling system of claim 3 wherein the length of the organic light emitting diode film is substantially the length between the opposing sides.

5. The information handling system of claim 4 wherein the gradient refractive index portion comprises lithium ions impregnated in the glass cover.

6. The information handling system of claim 4 wherein the gradient refractive index portion comprises glass deposited with varying refractive indexes.

7. The information handling system of claim 6 wherein the housing comprises first and second portions, the display integrated in the first portion, a keyboard integrated in the second portion.
