INFORMATION HANDLING SYSTEM FLEXIBLE DISPLAY BEZEL
An information handling system processes information with processing components disposed in housing portions rotationally coupled by a hinge and presents the information as visual images at a flexible display film disposed over the hinge to fold when the hinge rotates the housing portions from an open to a closed position. A bezel fits over the outer perimeter having a rigid portion and a flexible portion. The bezel flexible portion fits over the flexible display film at the hinge to support display film folding having managed torsional and compressive forces.
1 . An information handling system comprising:
first and second housing portions;
processing components disposed in the first and second housing portions and cooperating to process information;
a hinge rotationally coupling the first and second housing portions to each other;
a flexible display film disposed over the first and second housing portions and the hinge. The flexible display film interfaced with the processing components and operable to present the information as visual images; and
a bezel disposed about a perimeter of the flexible display, the bezel having a rigid portion and a flexible portion, the flexible portion disposed over the hinge to flex in response to hinge rotation for protection of the flexible display film over the hinge.
2 . The information handling system of claim 1 wherein:
the rigid portion comprises an outer layer of poly(methyl methacrylate) (PMMA) disposed over polycarbonate; and
the flexible portion comprises flexible silicon.
3 . The information handling system of claim 2 wherein the flexible silicon is formed having plural spaced slots disposed to compress the spaced slots at rotation from an open to a closed configuration.
4 . The information handling system of claim 1 wherein the polycarbonate forms to have an opening sized to accept a component under the PMMA.
5 . The information handling system of claim 4 wherein the component comprises a camera.
6 . The information handling system of claim 1 wherein:
the rigid portion comprises an outer layer of flexible silicon disposed over polycarbonate; and
the flexible portion comprises flexible silicon.
7 . The information handling system of claim 6 wherein the flexible silicon comprises liquid silicon rubber.
8 . The information handling system of claim 1 wherein:
both the rigid portion and flexible portion comprise a contiguous stainless steel sheet manufactured by rolling; and
the flexible portion comprises a portion in the direction vertical to rolling.
9 . The information handling system of claim 1 further comprising a polyurethane cellular foam cushion disposed between the bezel and the flexible display film.
10 . A method for manufacture of a portable information handling system, the method comprising:
rotationally coupling first and second housing portions with a hinge;
disposing a flexible display film over the first and second housing portions and the hinge;
rotating the first and second housing portions about the hinge between an open position having the flexible display film in a flat configuration and a closed position having the flexible display film folded at the hinge; and
protecting a perimeter of the flexible display film with a bezel coupled to the housing portions over the perimeter, the bezel having a rigid portion and a flexible portion, the flexible portion disposed over the hinge to flex in response to the rotating the hinge.
11 . The method of claim 10 wherein the protecting the perimeter further comprises:
manufacturing the bezel rigid portion with an outer layer of poly(methyl methacrylate) (PMMA) disposed over polycarbonate; and
manufacturing the bezel flexible portion with a flexible silicon.
12 . The method of claim 11 wherein the manufacturing the bezel rigid portion further comprises a multi-shot injection of PMMA and polycarbonate.
13 . The method of claim 12 wherein the manufacturing the bezel flexible portion further comprises a multi-shot injection of the flexible silicon with the PMMA and polycarbonate.
14 . The method of claim 10 further comprising forming the bezel flexible portion to have plural spaced slots disposed to compress together at rotation from the open to the closed configuration.
15 . The method of claim 10 wherein the protecting the perimeter further comprises:
manufacturing the bezel with rolled stainless steel; and
coupling the bezel over the hinge to fold in a direction vertical to a rolling direction of the stainless steel.
16 . The method of claim 10 further comprising:
disposing a polyurethane cellular foam cushion between the bezel and the flexible display film.
17 . The method of claim 16 wherein the bezel flexible portion comprises liquid silicon rubber that extends to the rigid bezel portion.
18 . An information handling system bezel comprising:
a rigid portion including polycarbonate having an interior circumference sized to cover an outer perimeter of a flexible display film; and
a flexible portion including flexible silicon sized to cover the outer perimeter of the flexible display film at a folding portion, the rigid portion integrated into a contiguous piece with the flexible portion.
19 . The information handling system bezel of claim 18 further comprising:
a PMMA material layer disposed over the polycarbonate; and
a camera integrated in a cavity formed in the polycarbonate.
20 . The information handling system of claim 19 further comprising:
a rolled stainless steel layer having rolling characteristics aligned with a vertical axis;
wherein the rolling characteristics align vertical to rolling over the flexible display film folding portion.
