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.

Abstract: An electronic display may include an active area having a first pixel formed in the active area, where the first pixel emits light in response to image data. The electronic display may also include a controller to transmit the image data to the first pixel. The first pixel may include an organic light-emitting diode that emits the light in response to the image data, memory to digitally store the image data received from the controller, and driver circuitry to receive the image data from the memory. The driver circuitry may cause the organic light-emitting diode to emit the light in response to the image data.

Abstract: A pixel circuit for an electronic display may include a memory to store a digital data signal indicative of a value within a data range. The pixel circuit may also include a light-emitting diode to emit light based at least in part on the digital data signal. The pixel circuit may also include an initialization transistor to initialize the pixel circuit before the light-emitting diode emits light and a driving transistor to activate based at least in part on the digital data signal.

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 pixel circuit for an electronic display may include a memory to store a digital data signal indicative of a value within a data range. The pixel circuit may also include a light-emitting diode to emit light based at least in part on the digital data signal. The pixel circuit may also include an initialization transistor to initialize the pixel circuit before the light-emitting diode emits light and a driving transistor to activate based at least in part on the digital data signal.
