Abstract: An electronic device may include a display having a monolithic array of light-emitting diodes mounted to a surface of a substrate layer. The diodes may include contact pads. Driver circuitry may independently drive each of the diodes in the array using drive signals. The driver circuitry may be formed on a driver integrated circuit. Bond pads may be formed on a surface of the integrated circuit. Copper pillars may be grown on the bond pads. In another suitable arrangement, the driver circuitry may be formed on a driver printed circuit board coupled to an interposer by a flexible printed circuit. The interposer may include bond pads and copper pillars grown on the bond pads. The contact pads on each of the diodes may be simultaneously bonded to the copper pillars. A surface of the substrate layer may be patterned to form light redirecting elements if desired.

Abstract: Display structures and methods of manufacture of display structure including a display panel with a curved three-dimensional film contour are described. In an embodiment, a display panel includes display area with a main body area and a plurality of petals extending from the main body area. The petals are folded into a curved three-dimensional (3D) film contour, and are separated by corresponding trenches between petals. The trenches may be filled with various seam hiding materials to visually obscure the trenches.

Abstract: A display system of a display includes multiple primary light emitting diodes and multiple secondary light emitting diodes. The multiple primary light emitting diodes may emit light, in which at least a first primary light emitting diode of the multiple primary light emitting diodes is shorted. Moreover, the multiple secondary light emitting diodes may emit light. At least a first secondary light emitting diode of the multiple secondary light emitting diodes is associated with the first primary light emitting diode, and the first secondary light emitting diode may emit light based at least in part on the first primary light emitting diode being shorted.

Abstract: An electronic device may have a display with an array of pixels. Each pixel may include inorganic light-emitting diodes of the same color such as a blue inorganic light-emitting diode. To emit different colors of light using the same type of inorganic light-emitting diodes, quantum dot layers may be used. Each quantum dot layer may have an associated reflective layer. Each light-emitting diode may also have an associated reflective layer. The reflective layer for the light-emitting diode may conform to the light-emitting diode or may be separated from the light-emitting diode by gap. When the reflective layer is separated from the light-emitting by a gap, the gap may be filled by a quantum dot layer or a diffusive layer.

Abstract: A display may be formed by an array of light-emitting diodes mounted to the surface of a display substrate. The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be configured to control one or more respective passive matrices. To control partial pixel cells in the display, a donor pixel control circuit in a partial pixel cell may control the pixels in a receptor partial pixel cell without a pixel control circuit. To mitigate the size of an inactive area of the display, fanout signal lines for the display may be formed in the light-emitting active area of the display. The fanout signal lines may be formed between a row of pixel control circuits and a bottom edge of the light-emitting active area.

Abstract: Embodiments describe a display integration scheme in which an array of pixel driver chips embedded front side up in an insulator layer. A front side redistribution layer (RDL) spans across and is in electrical connection with the front sides of the array of pixel driver chips, and an array of light emitting diodes (LEDs) is bonded to the front side RDL. The pixel driver chips may be located directly beneath the display area of the display panel.
