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: Systems and apparatuses for hybrid micro-driver architectures having time multiplexing for driving displays are described. In one embodiment, a display (e.g., hybrid display architecture) includes a backplane and a micro-driver circuitry that is coupled to the backplane. The backplane includes circuitry (e.g., sample and hold circuitry) for sampling and holding analog data and for time multiplexing analog data. The micro-driver circuitry includes at least a capacitor of a ramp generator for generating a ramp voltage based on the analog data of the backplane and drive circuitry to cause at least one emission pulse for emitting a display element.
