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.
