A display system of a display includes a first light emitting diode, a second light emitting diode, a current source, and at least one transistor. The first and the second light emitting diodes emit light. The current source provides a constant current to the first light emitting diode and the second light emitting diode. Moreover, the at least one transistor removes the current or shunts the current towards the first light emitting diode, the second light emitting diode, or both. Removing the current or shunting the current towards the first light emitting diode, the second light emitting diode, or both, may blend outputs of the first light emitting diode and the second light emitting diode.

Super pixel architecture for high dynamic range

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.

Stacked hybrid micro LED pixel architecture

An electronic display row drivers or column drivers that send reference currents or voltages to microdrivers to be used to drive micropixels to particular levels. The microdrivers, in turn, ship current to micropixels that display images based at least in part on the shipped current.

Electronic display emission scanning using row drivers and microdrivers

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.

Hybrid micro-driver architectures having time multiplexing for driving displays

Methods, systems, and apparatuses for controlling an emission of the light emitting devices are described herein. The light emitting devices may be light emitting diode (LED) devices including &#x3bc;LED devices or organic LED (OLED) devices. Emission control of the LED may be performed using a micro-scale driving circuit (e.g., &#x3bc;Driver) containing drive transistors for constant current driving of the light emitting devices. One embodiment provides for a display driver hardware circuit including emission logic, the emission logic including comparator logic to compare a data voltage from a storage capacitor to a voltage ramp provided via the TFT backplane, the comparator logic to cause the emission logic to generate an emission pulse to an LED device, and wherein the integrated circuit is to switch and drive a plurality of LED devices. In one embodiment each of the plurality of LED devices is a subpixel for a display device.
