An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed on a display panel substrate. A display panel may extend continuously across the display or multiple display panels may be tiled in two dimensions to cover a larger display area. Interconnect substrates may have outwardly facing contacts that are electrically shorted to corresponding inwardly facing contacts such as inwardly facing metal pillars associated with the display panels. The interconnect substrates may be supported by glass layers. Integrated circuits may be embedded in the display panels and/or in the interconnect substrates. A display may have an active area with pixels that includes non-spline pixels in a non-spline display portion located above a straight edge of the display and spline pixel in a spline display portion located above a curved edge of the display.

Electronic devices with borderless displays

A micro-light-emitting diode (LED) display includes a number of micro-LED pixel elements and multiple optical sensors integrated with the micro-LED pixel elements. A transparent conductor layer is disposed over the micro-LED pixel elements and optical sensors.

Embedded optical sensors in a micro-led display

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.

Local passive matrix displays

Micro LED and microdriver chip integration schemes are described. In an embodiment a microdriver chip includes a plurality of trenches formed in a bottom surface of the microdriver chip, with each trench surrounding a conductive stud extending below a bottom surface of the microdriver chip body. Integration schemes are additionally described for providing electrical connection to conductive terminal contacts and micro LEDs bonded to a display substrate and adjacent to a microdriver chip.
