Abstract
A flat panel display, such as a Field Emission Display ("FED"), is disclosed having a gray scale generator. Input into the display, initially, is an analog signal having an amplitude. The gray scale generator includes a converter for converting the analog input signal to a sawtooth output signal having a height and width. Further, the width of the sawtooth output signal is responsive to the analog input signal's amplitude.
