  • Publication number: 20190279553
    Abstract: A display device may include pixels that display image data. The display device may also include a circuit that receives pixel data having a gray level for at least one pixel, such that the pixel data corresponds to a frame of the image data and the frame includes sub-frames. The pixel data causes the circuit to provide at least one current pulse to the at least one pixel according to a first order of the sub-frames. The circuit may also receive a second order of the sub-frames, such that the second order is mapped with respect to the first order, and at least one current pulse is provided to the at least one pixel according to the second order. As such, visual artifacts depicted on the display are reduced.

  • Patent number: 10395594
    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 ?LED devices or organic LED (OLED) devices. Emission control of the LED may be performed using a micro-scale driving circuit (e.g., ?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.
