Abstract: To minimize the width of a non-light-emitting border region around an opening in the active area, data lines may be stacked in the border region. Data line portions may be formed using three metal layers in three different planes within the border region. A metal layer that forms a positive power signal distribution path in the active area may serve as a data line portion in the border region. A metal layer may be added in the border region to serve as a data line portion in the border region. Data line signals may also be provided to pixels on both sides of an opening in the active area using supplemental data line paths. A supplemental data line path may be routed through the active area of the display to electrically connect data line segments on opposing sides of an opening within the display.

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, may be formed from a mesh shaped metal pattern, may have L-shaped path segments, and may include laser-deposited metal on the cathode layer. Data lines may be formed from metal layers in the active area to accommodate the rounded corners of the display.

Abstract: A display may have organic light-emitting diode pixels formed from thin-film circuitry. The thin-film circuitry may be formed in thin-film transistor (TFT) layers and the organic light-emitting diodes may include anodes and cathodes and an organic emissive layer formed over the TFT layers between the anodes and cathodes. The organic emissive layer may be formed via chemical evaporation techniques. The display may include moisture blocking structures such as organic emissive layer disconnecting structures that introduce one or more gaps in the organic emissive layer during evaporation so that any potential moisture permeating path from the display panel edge to the active area of the display is completely terminated.

Abstract: A display may have an array of pixels such as liquid crystal display pixels. The display may include short pixel rows that span only partially across the display and full-width pixel rows that span the width of the display. The gate lines coupled to the short pixel rows may extend into the inactive area of the display. Supplemental gate line loading structures may be located in the inactive area of the display to increase loading on the gate lines that are coupled to short pixel rows. The supplemental gate line loading structures may include data lines and doped polysilicon that overlap the gate lines in the inactive area. In displays that combine display and touch functionality into a thin-film transistor layer, supplemental loading structures may be used in the inactive area to increase loading on common voltage lines that are coupled to short rows of common voltage pads.

Abstract: Methods and devices useful in discharging an aberrant charge on the VCOM of an electronic display and harvesting energy from the VCOM of the electronic display are provided. By way of example, a method may include supplying an activation signal to an active switching device of an electronic display. The active switching device is configured to discharge an aberrant charge on a common electrode of the electronic display. The method further includes discharging the aberrant charge by way of the active switching device. Discharging the aberrant charge comprises preventing a possible occurrence of image artifacts from becoming apparent on the electronic display.

Abstract: A display may include an active area with a first region and a second region. The first region may overlap an input-output component such as a camera and may have a higher transparency than the second region. The first region may have a lower pixel density than the second region. Signal lines that pass through the first region may have transparent portions that overlap the first region and opaque portions that overlap the second region. To mitigate artifacts caused by high resistance of the transparent portions of the signal lines, the signal lines may include supplemental opaque portions that are electrically connected in parallel to the transparent portions and that are routed through the second region around the first region.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To mitigate artifacts caused by a light emitter operating through a display, the display may have a higher density of thin-film transistor sub-pixels than emissive sub-pixels. This allows for a region in the display to include emissive sub-pixels but be free of thin-film transistor sub-pixels. The light emitter may operate through this region in the display. Additionally, to reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels.
