Abstract

An electronic device housing may have upper and lower portions that are attached with a hinge. At least one portion of the housing may have a rear planar surface and peripheral sidewalls having edges. A display module may be mounted in the housing. The display module may have glass layers such as a color filter glass layer and a thin-film transistor substrate. The color filter glass layer may serve as the outermost glass layer in the display module. The edges of the display module may be aligned with the edges of the peripheral housing sidewalls to create the appearance of a borderless display for the electronic device. The display module may be provided with an opening that allows a camera or other electronic components to receive light. Traces may be provided on the underside of the thin-film transistor substrate to serve as signal paths for the electrical components.

Claims

1. A portable computer, comprising:

upper and lower housings coupled by a hinge;

a display in the upper housing that includes a rectangular color filter layer, a rectangular thin-film transistor layer, and at least one polarizer layer, wherein the color filter layer has a rectangular periphery with a peripheral edge; and

a structure located along the peripheral edge of the color filter layer and at least partially surrounding the periphery of the color filter layer, wherein the upper housing has an inner edge surface that runs parallel to at least some of the peripheral edge of the color filter layer and wherein the structure is interposed between at least some of the inner edge surface of the upper housing and the peripheral edge of the color filter layer and provides an interface between the color filter layer and the upper housing.

2. The portable computer defined in claim 1 wherein the structure comprises an elastomeric structure.

3. The portable computer defined in claim 1 wherein the structure comprises a gasket.

4. The portable computer defined in claim 1 wherein the upper housing comprises metal and wherein the structure rests on the metal.

5. The portable computer defined in claim 1 wherein the upper housing has a planar surface that supports the thin-film transistor layer.

6. The portable computer defined in claim 1 wherein the display includes an opaque border that covers inactive portions of the display.

7. The portable computer defined in claim 6 wherein the opaque border has an opening, the portable computer further comprising a camera configured to receive light through the opening.

8. The portable computer defined in claim 7 wherein the polarizer layer has an opening aligned with the opening in the opaque border.

9. The portable computer defined in claim 8 wherein the opaque border comprises a peripheral ring of opaque material.

10. The portable computer defined in claim 9 wherein the peripheral ring of opaque material comprises ink.

11. The portable computer defined in claim 9 wherein the peripheral ring of opaque material comprises a polymer film layer.

12. The portable computer defined in claim 1 wherein the upper housing has a planar surface that supports at least some of the display.

13. The portable computer defined in claim 12 wherein the planar surface comprises a ledge that supports the thin-film transistor layer.
