Bezels for foldable displays
A multi-layer bezel for a flexible information handling system (IHS) display may include a die-cut polycarbonate rectangular frame layer, a die cut low durometer foam layer, aligned with and disposed below the polycarbonate rectangular frame layer and a polymer layer aligned with the polycarbonate rectangular frame layer. In various implementations the rectangular frame layer may have a first open-sided rectangular frame segment and a complementary second open-sided rectangular frame segment. The die-cut polycarbonate may be transparent and back-printed with sensor openings for IHS components. The bezel may be a multi-layer stack-up that is die cut to define the bezel. Alternatively, the bezel may be defined by a domed polyurethane upper layer disposed on the die cut polycarbonate rectangular frame layer on a side of the polycarbonate rectangular frame layer opposite the die cut low durometer foam layer.
1 . A multi-layer bezel for a flexible information handling system (IHS) display comprising:
a polycarbonate rectangular frame layer comprising two thin transparent polycarbonate sheets and at least one elastomer strip disposed between adjacent edges of the polycarbonate sheets, wherein the frame layer is folded along the at least one elastomer strip;
a polymer layer aligned with the polycarbonate rectangular frame layer, wherein the polymer layer is disposed beneath the frame layer and adhered to the polycarbonate sheets and to the at least one elastomer strip of the frame layer; and
a die-cut foam layer, aligned with and disposed below the polymer layer and sealing the bezel to a panel of the display.
2 . The bezel of claim 1 , wherein the polycarbonate rectangular frame layer comprises a first open-sided rectangular frame segment and a complementary second open-sided rectangular frame segment.
3 . The bezel of claim 1 , wherein the polycarbonate rectangular frame is transparent and back-printed with sensor openings for IHS components.
4 . The bezel of claim 3 , wherein the IHS components comprise one or more of a camera, ambient light sensor, light emitting diode infrared/facial recognition camera, microphone, and hall sensor.
5 . The bezel of claim 1 , wherein the transparent polycarbonate sheets provide structural rigidity to the bezel.
6 . The bezel of claim 1 , wherein the transparent polycarbonate sheets are back-printed.
7 . The bezel of claim 1 , wherein the at least one elastomer strip comprises a synthetic rubber strip.
8 . The bezel of claim 1 , wherein the at least one elastomer strip comprises a silicone foam rubber strip.
9 . The bezel of claim 1 , wherein the at least one elastomer strip comprises a texture that promotes the folding of the frame layer and that is disposed on a top surface of the elastomer strip.
10 . The bezel of claim 1 , wherein the at least one elastomer strip comprises a composite elastomer strip comprising a central strip of higher durometer rigid elastomer and strips of lower durometer elastomer foam on either side of the central strip of higher durometer rigid elastomer disposed between an edge of each of the polycarbonate sheets and the central strip of higher durometer rigid elastomer.
11 . The bezel of claim 1 , wherein the foam layer comprises an inner polyurethane foam sheet and an outer pressure sensitive adhesive border.
12 . The bezel of claim 1 , further comprising machine finished chamfers along inner and outer perimeters of the bezel.
13 . The bezel of claim 1 , wherein the polymer layer aligned with the polycarbonate rectangular frame layer comprises a polyurethane upper layer disposed on the polycarbonate rectangular frame layer on a side of the polycarbonate rectangular frame layer opposite the die-cut foam layer.
14 . An Information Handling System (IHS), comprising:
a flexible display; and
a multi-layer bezel adhered to the flexible display comprising:
a polycarbonate rectangular frame layer comprising two thin transparent polycarbonate sheets and at least one elastomer strip disposed between adjacent edges of the polycarbonate sheets, wherein the frame layer is folded along the at least one elastomer strip;
a polymer layer aligned with the polycarbonate rectangular frame layer, wherein the polymer layer is disposed beneath the frame layer and adhered to the polycarbonate sheets and to the at least one elastomer strip of the frame layer; and
a die-cut foam layer, aligned with and disposed below the polymer layer and sealing the bezel to a panel of the display.
15 . The IHS of claim 14 , wherein the polymer layer aligned with the polycarbonate rectangular frame layer comprises a polyurethane upper layer disposed on the polycarbonate rectangular frame layer on a side of the polycarbonate rectangular frame layer opposite the die-cut foam layer.
16 . A foldable computer display comprising:
a polycarbonate rectangular frame layer comprising two thin transparent polycarbonate sheets and at least one elastomer strip disposed between adjacent edges of the polycarbonate sheets, wherein the frame layer is folded along the at least one elastomer strip;
a polymer layer aligned with the polycarbonate rectangular frame layer, wherein the polymer layer is disposed beneath the frame layer and adhered to the polycarbonate sheets and to the at least one elastomer strip of the frame layer; and
