Abstract
Requirements on instrumentation for automotive navigation systems are discussed, and liquid crystal display (LCD) equipment developed for this purpose is described. A direct multiplexed full-color LCD having 320*200 trio dots was developed and applied to a graphic display unit. Through the use of the newly developed COG (chip-on-glass) technology, a small and thin display module was realized. A route guidance indicator was developed using a segment-type LDC and a monochromatic dot-matrix LCD, and it was applied to an actual automotive navigation system. This indicator displays such information as the form and name of crossings as a car approaches it. Not only can it show the extracted principle information, but it can also be mounted at a place near the driver's regular eye position. For these reasons, this indicator is useful for improving the information cognitivity of navigation systems.<>
