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.

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.
