Abstract: Methods and apparatuses relating to controlling an emission of a display panel. In one embodiment, a display driver hardware circuit includes row selection logic to select a number of rows in an emission group of a display panel, wherein the number of rows is adjustable from a single row to a full panel of the display panel, column selection logic to select a number of columns in the emission group of the display panel, wherein the number of columns is adjustable from a single column to the full panel of the display panel, and emission logic to select a number of pulses per data frame to be displayed, wherein the number of pulses per data frame is adjustable from one to a plurality and a pulse length is adjustable from a continuous duty cycle to a non-continuous duty cycle.

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.
