Abstract
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 μLED devices or organic LED (OLED) devices. Emission control of the LED may be performed using a micro-scale driving circuit (e.g., μDriver) 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.
