An ESD protection system for an image sensor array includes a two-dimensional array of pixels formed on a substrate. Each of the pixels is connected to a gate line and a data line. The system includes a common ESD bus and at least one ESD protection circuit formed on the substrate. The protection circuit includes: a pair of thin film transistors connected in a back-to-back configuration with a first terminal connected to one of the gate lines, and a second terminal connected to the common ESD bus. Upon the occurrence of an electrostatic discharge onto the gate line causing the voltage across the terminals to exceed a threshold value, the protection circuit discharges the ESD charge from the gate line to the ESD bus, thereby preventing damage to each of the switching transistors in the pixels connected to the gate line.
