Field emitter structure for flat screen display

摘要

The field emitter structure has upper and lower parallel plates made up of a network of pixels having several emitter mechanisms (21). Each mechanism has the grid electrode set to a constant voltage. The pixels are voltage fed by a sweep command circuit (30) commanded from digital words. A thin film transistor (22) applies the high voltage to the pixel network. The pixel network, sweep circuit, digital command and transistor thin film are integrated on a single substrate.
