Title: Very low duty cycle pulse width modulator
Inventor: PRAISWATER MICHAEL R
IPC: G09G3/34
Filed: 1997-10-09
Abstract: An apparatus which outputs very low duty cycle pulses of a consistent width.  It is common to use a pulse width modulator as part of a liquid crystal display dimming system to vary the brightness.
