Abstract
Rise of FPD caused the end of the manufacture of CRT, and the achievement of the next generation master monitor using FPD device has become a pressing issue for broadcasting stations. Recently, FPD devices such as LCD and PDP are making certain progress in their characteristics, however they have not caught up with CRT yet. Moreover, FED which has almost ideal characteristics is unfortunately not at mass production stage now. Master monitor is the standard of the video quality evaluation expressed as an analog quantity in the final stage of various digital processing. Without persisting in LCDs, adoption of the device that truly fills the master monitor's demand is requested.
