    Abstract: A display may have a liquid crystal layer sandwiched between a thin-film transistor layer and a color filter layer. An upper polarizer may be placed on top of the thin-film transistor layer. A lower polarizer may be placed under the color filter layer. Components may be bonded to bond pads on the inner surface of the thin-film transistor layer using anisotropic conductive film. Bond quality may be assessed by probing probe pads that are coupled to the bond pads or by visually inspecting the bond pads through the thin-film transistor layer. Opaque masking material in the inactive area may be provided with openings to accommodate the bond pads. Additional opaque masking material may be placed on the underside of the upper polarizer and on the upper surface of the thin-film transistor layer to block the openings from view following visual inspection.

    Abstract: A display may have a layer of liquid crystal material interposed between a color filter layer and a thin-film transistor layer. A ring of adhesive sealant may surround the liquid crystal layer. Columns spacers may extend between the color filter and thin-film transistor layers through the liquid crystal layer to help ensure that the color filter and thin-film transistor layers are appropriately spaced apart from each other. A ring-shaped polymer spacer may surround the ring of adhesive sealant and may help protect display structures form exposure to etchant that is used to treat the edges of glass layers in the display. The spacer may be formed from the same layer of material that forms the column spacers. A black masking layer may be formed on the underside of the color filter layer using techniques that prevent the formation of protruding edge portions.

    Abstract: An electronic device is provided with a display such as a liquid crystal display mounted in an electronic device housing. The display includes a glass display layer such as a glass color filter substrate. A polarizer layer is formed on the glass display layer. To ensure that the peripheral edge of the polarizer layer matches the peripheral edge of the glass display layer, a laser beam scanning system is used to trim edge portions of the polarizer layer that overhang the glass display layer. The laser beam scanning system includes a moving laser beam that makes multiple scans along the edge of the polarizer layer. To prevent damage to the glass display layer during trimming operations, a characteristic of the moving laser is modified in between successive scans such that the energy density of the laser cut is reduced as the laser beam approaches the surface of the glass.

    Abstract: A display such as a liquid crystal display has a display substrate that includes a layer of liquid crystal material sandwiched between a color filter layer and a thin-film-transistor layer. An oversized polarizer is laminated to the surface of the display substrate. Laser-based polarizer trimming equipment is used to trim away excess portions of the polarizer from the display substrate. A thickness gauge gathers thickness information from the laminated polarizer and display substrate. The thickness information is used to adjust the position of a laser relative to the polarizer during polarizer trimming operations. The laser beam moves along a cutting path that is unique to the display substrate. A vision system performs an inspection to determine whether the display substrate is damaged following polarizer trimming operations. Based on the inspection, laser parameters may be adjusted prior to performing polarizer trimming operations on additional polarizers and display substrates.

    Abstract: An electronic device is provided with a display such as a liquid crystal display. The display has a layer of liquid crystal material sandwiched between an upper display layer such as a color filter layer and a lower display layer such as a thin-film-transistor layer. An upper polarizer is formed on the upper surface of the color filter layer. A lower polarizer is formed on the lower surface of the thin-film-transistor layer. To protect display layers such as the color filter layer and the thin-film-transistor layer, a coating is deposited on a peripheral edge of the display layer. A laser is used to cut through portions of the polarizer that overhang the display layer while also cutting through the coating on the peripheral edge of the display layer. Following laser trimming operations, the coating is flush with an edge surface of the polarizer.
