Abstract: An organic light-emitting diode display may have thin-film transistor circuitry formed on a substrate. The display and substrate may have rounded corners. A pixel definition layer may be formed on the thin-film transistor circuitry. Openings in the pixel definition layer may be provided with emissive material overlapping respective anodes for organic light-emitting diodes. A cathode layer may cover the array of pixels. A ground power supply path may be used to distribute a ground voltage to the cathode layer. The ground power supply path may be formed from a metal layer that is shorted to the cathode layer using portions of a metal layer that forms anodes for the diodes, may be formed from a mesh shaped metal pattern, may have L-shaped path segments, may include laser-deposited metal on the cathode layer, and may have other structures that facilitate distribution of the ground power supply.

Abstract: A wearable device is described. The wearable device includes a first display portion and a second display portion. The first display portion is located in front of eyes of a user to provide a high-resolution view of a virtual image of a virtual scene. The second display portion is located in front of the eyes of the user to provide a view of the user's nose. The second display portion can optionally occlude an area around the nose and optionally provide an effect of virtual lighting falling on the nose. The wearable device presents a view of the user's real nose as it would appear in a virtual scene.

Abstract: A projection-type display apparatus includes a liquid crystal panel including a panel pixel, an optical path shifting element that shifts a projected pixel projected from the panel pixel, and a display control circuit that controls the liquid crystal panel and the optical path shifting element. The display control circuit supplies, to the liquid crystal panel, the same data signal and controls the projected pixel to be at a same position in each of a unit period f1-1 and a unit period f2-1, and controls the optical path shifting element to cause a shift direction from the projected pixel before the shift toward the projected pixel after the shift from a unit period f1-2 to a unit period f1-4 to be opposite to the shift direction from the projected pixel before the shift toward the projected pixel after the shift from a unit period f2-2 to a unit period f2-4.
