[8] From 1959 to 1979 he did theoretical work on tunnel diodes, semiconductor device theory and experiment, injection luminescence, field emission, pattern recognition, later turning his interest to thin film technology.

[8][9][10][11] The cathode ray tube, like the brontosaurus, will become extinct, and for the same reason: too much bulk, very little brain.Over the years 1968–79, Brody developed many electronic uses for thin film transistors, including flexible circuits, aircraft power controls, industrial timers and others.

This venture was funded in part by Jerome Wiesner, Richard Leghorn of Itek, and Apple's John Sculley, and won contracts worth $7.8 million from the Defense Advanced Research Projects Agency (DARPA).

The company is concentrating on the development and commercial production of low cost active matrix backplanes for emerging display technologies, including AM-OLED.

[8] A SID award, the Peter Brody Prize was created in 2017 to honor outstanding contributions of young researchers to active matrix information display technology.
