18 August 1998 3-in. densely packed YAG phosphor screen for HDTV projection CRT
Author Affiliations +
New 3-in. RGB densely packed YAG phosphor screens with a new green phosphor for HDTV projection CRT have been developed. The screens is fabricated using a centrifugal sedimentation method. The 10% screen spot diameter is 0.18 mm and the luminance of green phosphor screen is 7 X 104 cm/m2 at a cathode current of 0.5 mA and anode voltage of 29 KV. An experimental 48-in. TV set using the densely packed YAG projection CRT has very high resolution and 250 cd/m2 luminance.
