Abstract: A hybrid display may include different display portions with different resolutions. The high resolution display portion may be positioned in a main viewing area for the viewer whereas the low resolution display portion may be positioned in a peripheral viewing area. The high resolution display portion may have a silicon backplane. The low resolution display portion may have a different type of backplane such as a thin-film transistor backplane. The different display portions may optionally share a common organic light-emitting diode layer such that light is emitted from the same plane across both display portions. The high resolution display portion may emit light through a transparent window in the low resolution display portion. A high resolution display may also be formed by separately forming a frontplane and a backplane. Conductive attachment structures such as indium bumps may be used to mechanically and electrically connect the backplane to the frontplane.

Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower and higher resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.

Abstract: Systems and methods are provided for electrical testing to supplement or replace optical testing of an electronic display. Internal testing circuitry that includes analog front end (AFE) and analog-to-digital converter (ADC) circuitry may be included in the electronic display and may be used either alone or in combination with other testing devices to perform electrical characterization and defect screening. The electrical characterization and defect screening may be performed before or after self-emissive elements such as light-emitting diodes are installed, further improving yield. Types of electrical characterization and defect screening may include a partial passive mode electrical characterization of OLEDs, vertical or horizontal crosstalk measurement, scan line integrity testing, pixel bright dot testing, display pixel defect detection, and delayed defect detection for defects that may occur after some extended period of time (e.g., after several minutes, after several hours).

Abstract: A display has rows and columns of pixels (22). A data line (Dn) in each column provides image data signals to the pixels of that column. Each row has first and second control lines (select[m], monitor[m]) coupled to the gates of first and second respective transistors (SE, MO) in each pixel. A third transistor in each pixel serves as a drive transistor (DR) and is coupled in series with a light-emitting diode (30) between positive and ground power supply voltages (VDD, VSS). A display driver circuitry in the display characterizes each of the light-emitting diodes in a column using the data line in an adjacent column from that light-emitting diode. Each of the drive transistors in a column is characterized using the data line in that column and the data line in an adjacent column.

Abstract: Systems and methods may reduce or eliminate image artifacts due to a defective pixel of an electronic display. An electronic display may include pixels that respectively include a self-emissive element, pixel drive circuitry that supplies a pixel drive current to drive the self-emissive element, and signal routing circuitry that reduces or eliminates a visual artifact due to a defective pixel among the pixels. The signal routing circuitry may do this by turning off the self-emissive element, supplying image data from the pixel drive circuitry to a first adjacent pixel, or receiving image data from other pixel drive circuitry from the first adjacent pixel or a second adjacent pixel.
