Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode that emits light under control of a drive transistor. The organic light-emitting diodes may have a common cathode layer, a common electron layer, individual red, green, and blue emissive layers, a common hole layer, and individual anodes. The hole layer may have a hole injection layer stacked with a hole transport layer. Pixel circuits for controlling the diodes may be formed from a layer of thin-film transistor circuitry on a substrate. A planarization layer may cover the thin-film transistor layer. Lateral leakage current between adjacent diodes can be blocked by shorting the common hole layer to a metal line such as a bias electrode that is separate from the anodes. The metal line may be laterally interposed between adjacent pixels and may be formed on the planarization layer or embedded within the planarization layer.

Abstract: An electronic device may have a flexible display. The display may have portions that are bent along a bend axis. The display may have display circuitry such as an array of display pixels in an active area and signal lines, thin-film transistor support circuitry and other display circuitry in an inactive area of the display surrounding the active area. The display circuitry may be formed on a substrate such as a flexible polymer substrate. The flexible polymer substrate may be formed by depositing polymer on a support structure that has raised portions. The raised portions may create locally thinned regions in the flexible polymer substrate. The reduced thickness of the flexible polymer substrate in the thinned regions may help ensure that a neutral stress plane that is associated with bending the display along the bend axis is aligned with the display circuitry, thereby minimizing stress in the display circuitry.

Abstract: A display may have an array of pixels controlled by display driver circuitry. The display driver circuitry may supply the pixels with data signals over data lines in columns of the pixels and may supply the pixels with gate line signals over gate lines in rows of the pixels. The display driver circuitry may have a display driver integrated circuit located on one of the edges of the display. The display driver circuitry may also have gate driver integrated circuits that extend along opposing edges of the display to form a pair of shift registers. Conductive lines in a display substrate may be coupled to opposing ends of the shift registers and to intermediate locations within the shift registers to minimize delays in distributing a gate high voltage signal from the display driver integrated circuit to the shift registers.

Abstract: A display has an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The pixels may be liquid crystal display pixels. Each pixel may have a common electrode voltage terminal. The display may have a transparent conductive film that forms a common electrode voltage layer that overlaps that array and that is shorted to the common electrode voltage terminals of the pixels. Metal common electrode voltage lines may run across the transparent conductive film to reduce resistance. Metal common electrode voltage paths that are coupled to the metal common electrode voltage lines may run along the left and right edge of the display. Common electrode voltage compensation circuits may receive feedback from the metal common electrode voltage paths. There may be two or more common electrode voltage compensation circuits for both the left and right edges of the display.

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.
