    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 system includes an array of light emitting diodes (LEDs), first and second driver chips, and one or more protection chips on a display substrate. The first and second driver chips are to drive a first group of LEDs of the array of LEDs and a second group of LEDs of the array of LEDs, respectively. Each protection chip includes one or more electro-static discharge (ESD) protection devices to assist with protecting the driver chips from damage caused by an ESD event. In one embodiment, each ESD protection device is connected between one or more signal lines, one or more power supply voltage lines, and an electrical ground line of the display substrate. In one embodiment, at least one protection chip comprises one or more electric overstress (EOS) protection devices to assist with protecting the driver chips from damage caused by an EOS event.
