Abstract
A numerical display cell (nine digits of seven segments) with nematic liquid crystals can be driven in a dynamic or a static mode. The static mode combines a flicker-free display with optimum contrast, but it has the drawback of a large number of interconnections (63). This paper describes a method to reduce this number to only four: a 63-b buffer memory in the form of an I2L shift register is attached directly to the glass plate carrying the electrode pattern. The required transparent electrode patterns provided with metallized contacts are prepared by means of thin-film techniques.Keywords
