Abstract: To reduce image artifacts and non-uniformity associated with a display pixel of an electronic display, processing circuity may adjust a luminance value corresponding to a display pixel according to a per-pixel gain mask, a per-pixel anode mask, or both. To further correct for the non-uniformity, the processing circuitry may convert the luminance value to a digital code based on a curve associated with an anode on which the display pixel is located.

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: A display device includes a voltage source that provides a voltage and a current source that provides a current. The display device also includes light emitting diodes (LEDs) that emit light to display an image on the display device. Additionally, the display device includes pixel driving circuitry that drives the LEDs using the voltage or the current. In particular, the pixel driving circuitry provides the LEDs with the voltage from the voltage source for a first period of time to enable the LEDs to reach an illumination threshold. Moreover, the pixel driving circuitry, after providing the voltage from the voltage source for the first period of time, drives the LEDs using the current from the current source to cause the LEDs to emit light substantially uninterrupted when changing between providing the voltage from the voltage source to driving the one or more LEDs using the current source.

Abstract: A pulse width modulation and amplitude modulation driving system for a display panel, including related circuits and methods of operation, are described. In an embodiment, a display panel includes a thin film transistor layer comprising a plurality of subpixel circuits. Each subpixel circuit may include a drive transistor, a comparator, and a switch. A plurality of light emitting diodes (LEDs), such as micro-LEDs, may be connected to the plurality of subpixel circuits. Each subpixel circuit can control an LED based on a current amplitude controlled by the drive transistor and a current pulse width controlled by the comparator and the switch. Other aspects are also described and claimed.
