Abstract
While active matrix liquid crystal displays (AMLCDs) are challenging CRT displays for projection and direct view applications, their overall performance must improve before they can displace the venerable CRT while fending off competition from developing technologies. Amorphous silicon, poly-silicon and reflective panels each have benefits but also trade-offs in performance.Selecting between the panels alone can be difficult as aperture ratios, heat handling, size, cost and other factors must be considered. Compared to CRTs and digital light processing technology, AMLCDs must be judged in the areas of greyscale tracking, black levels, signal transmission, multi-screen edge matching, non- standard signal resizing and color temperature adjustment, to name a few. Through experience and experimentation, electrohome has developed a 'wish list' of performance requirements for AMLCDs. This paper will provide, in its conclusion, recommendations on areas for improvement of AMLCD technology.
