A YAG Projection CRT and Projection Display

YAG(yttrium aluminum garnet) projection CRT which luminance for green color is more than 6.5×105cd/m2 at the beam current of 5mA and spot size is less than 80 m at the cathode current 1.0mA has been developed. A projection display in which the YAG projection CRT is employed gets a fine quality picture on the 48-in. rear projection display that horizontal resolution is more than 1000TVL, the peak brightness on the screen is 1500cd/m2 and the contrast ratio is 100.
