Liquid Crystal Automotive Displays, Present Possibilities — Future Technology Trends 820007

Twisted nematic (TN) liquid crystal display technology has now attained a level of maturity which matches the uncompromising requirements for its implementation in automobiles. Present day performance of TN-LCD’s is analysed in terms of basic intrinsic properties, cell technology performance and polarizer quality.
Future developments aim at higher information densities and increased system reliability, they include the incorporation of integrated driver circuits on the glass substrate of the display.
Other LC display technologies as e.g. dichroic displays shall become available for dashboards; they greatly profit from the cell technology experience gained through TN-LCDs, yet their performance has still to be improved through progress in LC and dye material research.
