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.

Abstract: Laser processing techniques may be used to form structures for electronic devices. A laser processing system may be provided with lasers and positioners for moving laser beams across a structure to be processed such as a layer of glass or other material. A laser such as a pulsed infrared laser may be move along a path across the layer of material. The laser may create a series of damaged regions along the path. A portion of the layer may be removed from other portions of the layer by breaking off the portion of the layer along the path. Laser-induced heating techniques and mechanical stress-inducing techniques may be used to impart stress to the layer of material to help break off the portion. The layer may include one or more sublayers such as layers of glass substrate material in a display.

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.
