Abstract

A large number of gray shades can be displayed in rms responding displays by using integer wavelets. The technique is demonstrated by displaying 64 gray shades in a twisted nematic liquid crystal display. We have reduced the hardware complexity of the display drivers by adding a few analog multiplexers that are common to a large number of stages (one for each output) in the drivers. A simple controller was implemented in a low cost complex programmable logic device.
