Abstract

Dimension Technologies Inc. has devised and experimentally validated a technique for producing field-sequential-color illumination for liquid crystal displays (LCDs) that does not exhibit image breakup and can provide flicker free images at slower refresh speeds than other field-sequential-color techniques. The technique involves a combination of colored illumination patterns that are sequentially imaged within the pixels of an LCD. An optical bench version of this type of illumination system was used to evaluate the ability to produce white light, evaluate flicker performance, evaluate image breakup visibility, and perform reading tests. This work can lead to a superior means of producing color displays using monochrome LCDs. Application of the research by LCD manufacturers may allow that industry to produce simplified, less costly LCDs for color displays.
