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.

Displays with data lines that accommodate openings

An electronic device includes a frame and a display stack. The frame defines a first part of an interior volume. The display stack includes a cover attached to the frame. The cover may define a second part of the interior volume. The display stack also includes an array of organic light-emitting diodes (OLEDs) including an array of emissive electroluminescent (EL) regions, and at least one organic photodetector (OPD) disposed between the cover and at least one emissive EL region in the array of emissive electroluminescent regions. The at least one emissive EL region emits light through the at least one OPD. In alternative embodiments, the OLEDs may be stacked on the OPDs, or the OLEDs and OPDs may be interspersed with each other instead of stacked.

Display stack with integrated photodetectors

Systems and methods for detection of incident light are described. An optical imaging sensor is positioned at least partially within an active display area of a display and is configured to detect and characterize one or more properties of light incident to the active display area of the display.

Sensing system for detection of light incident to a light emitting layer of an electronic device display

A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. The organic light-emitting diodes may be interposed between a substrate () and a cover layer (). The organic light-emitting diodes may be white light-emitting diodes () that emit white light that is filtered through a color filter array () to produce colored light. The color filter array may be located above or below the array of light-emitting diodes. A microcavity may be formed between the substrate () and each light-emitting diode (). The microcavity may be formed from an anode () in the light-emitting diode and first () and second layers () with different refractive indices. The low-refractive-index layer may be formed from a color filter in the color filter array. Light from the light-emitting diode may resonate within the microcavity beneath each light-emitting diode before exiting the display as colored light.

Displays with white organic light-emitting diodes

A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. Each pixel may include organic layers interposed between an anode and a cathode. The organic layers may emit out-coupled light that escapes the display and waveguided light that is waveguided within the organic layers. A reflector may be placed at the edge of the organic layers to reflect the waveguided light out of the display. The reflector may be located within a pixel definition layer and may be formed from metal or may be formed from one or more interfaces between high-refractive-index material and low-refractive-index material. The reflector may be formed from an extended portion of the pixel anode. The reflector may be formed from light-reflecting particles that are suspended in the pixel definition layer.

Organic light-emitting diode displays with reflectors

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.

Backplane structure and process for microdriver and micro LED

A component such as a display may have a substrate and thin-film circuitry on the substrate. The thin-film circuitry may be used to form an array of pixels for a display or other circuit structures. Metal traces may be formed among dielectric layers in the thin-film circuitry. Metal traces may be provided with insulating protective sidewall structures. The protective sidewall structures may be formed by treating exposed edge surfaces of the metal traces. A metal trace may have multiple layers such as a core metal layer sandwiched between barrier metal layers. The core metal layer may be formed from a metal that is subject to corrosion. The protective sidewall structures may help prevent corrosion in the core metal layer. Surface treatments such as oxidation, nitridation, and other processes may be used in forming the protective sidewall structures.

Electrical components having metal traces with protected sidewalls

An organic electroluminescence display panel that includes a plurality of first pixel areas, a plurality of second pixel areas, and a plurality of third pixel areas is provided. The organic electroluminescence display panel includes a first electrode layer, an organic layer including a light-emitting layer made of organic light-emitting material and a second electrode layer. The first electrode layer includes a reflective material. The organic layer is located on the first electrode layer. The second electrode layer is located on the organic layer. The material of the second electrode layer includes a transparent metal oxide conductive material. The thickness of the second electrode layer is a single thickness and is greater than 300 nm.
