    摘要： A field emission display includes electrostatic discharge protection circuits coupled to an emitter substrate and an extraction grid. In the preferred embodiment, the electrostatic discharge circuit includes diodes reverse biased between grid sections and a first reference potential or between row lines and a second reference potential. The diodes provide a current path to discharge static voltage and thereby prevent a high voltage differential from being maintained between the emitter sets and the extraction grids. The diodes thereby prevent the emitter sets from emitting electrons at a high rate that may damage or destroy the emitter sets. In one embodiment, the diodes are coupled directly between the grid sections and the row lines. In one embodiment, the diodes are formed in an insulative layer carrying the grid sections. In another embodiment, the diodes are integrated into the emitter substrate.

    摘要： A field emission display includes an emitter driving circuit for providing current to emitters in the display. The emitter driving circuit includes a current mirror to monitor actual current to each pixel in the array. The actual current is then compared to a reference current derived from an image signal based upon an expected current draw of the emitter to produce an error signal. The error signal is fed back to the input of the emitter driver circuit and the emitter driver circuit produces a corrected emitter current in response. During transitions in the image signal, error detection is briefly disabled to allow the emitter driver circuit to respond to the image signal.
