  "title": "Electronic devices with thin display housings",
  "abstract": "An electronic device may have a housing formed from a rigid material such as metal or fiber-composite material. A display such as an organic light-emitting diode display may be attached to a planar wall portion of the housing using a layer of adhesive. A display cover layer may be attached to the organic light-emitting diode with a layer of adhesive. The adhesive layers may be rigid to enhance device stiffness. The housing may have curved sidewall portions that extend outwardly from the planar wall portion to enhance stiffness. The organic light-emitting diode display may have an array of pixels formed from thin-film transistor circuitry. The thin-film transistor circuitry may be formed on a substrate such as a glass substrate that is attached to the planar wall portion. The organic light-emitting diode display may have a circular polarizer that is attached to the thin-film transistor circuitry.",
  "claims": [
    "1. An electronic device, comprising: a housing having a planar housing wall portion, wherein the housing comprises carbon fiber composite material, wherein the housing has perpendicular first and second edges, and wherein the carbon-fiber composite material has carbon fibers that extend along a direction that is not parallel with the first edge and that is not parallel with the second edge; a display cover layer; an organic light-emitting diode display having a first surface attached to the display cover layer with a first layer of adhesive and an opposing second surface attached to the planar housing wall portion with a second layer of adhesive.",
    "2. The electronic device defined in claim 1 further comprising at least one hinge at a corner of the planar housing wall portion.",
    "3. The electronic device defined in claim 2 wherein the carbon fibers are fibers in a woven fabric and wherein the carbon-fiber composite material includes a polymer binder in which the woven fabric is embedded.",
    "4. An electronic device, comprising: a first housing and a second housing that rotate relative to each other, wherein the first housing comprises a planar wall portion of stainless steel and a curved sidewall that extends from the planar wall portion; an organic light-emitting diode display having a glass substrate layer that is directly attached to the first housing with a first layer of adhesive, having a thin-film transistor layer on the glass substrate layer, and having a polarizer attached to the thin-film transistor layer; and a display cover layer that overlaps the curved sidewall.",
    "5. The electronic device defined in claim 4, wherein the display cover layer that is attached to the polarizer with a second layer of adhesive.",
    "6. The electronic device defined in claim 4 wherein the housing and display have a combined thickness of less than 2 mm.",
    "7. The electronic device defined in claim 4 wherein the first housing comprises: a first layer of material; and a second layer of material selected from the group consisting of: fiber composite material and metal, wherein the second layer of material is interposed between the first layer of material and the organic light-emitting diode display.",
    "8. The electronic device defined in claim 7 wherein the first layer of material comprises a metal cladding layer."
