PLASMA DISPLAY UNIT AND VIDEO DISPLAY SYSTEM USING IT |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a plasma display apparatus with improved panel luminous efficiency. SOLUTION: A phosphor Zn<SB>2</SB>SiO<SB>4</SB>:Mn and rear earth terbium (Tb) of which green color is deeper than that of a direct view cathode ray tube color television and oxide phosphor activated as a light emission center are put in the same phosphor layer to realize a green phosphor layer of higher brightness. For example, Y<SB>3</SB>(Al<SB>x</SB>Ga<SB>1-x</SB>O<SB>12</SB>:Tb (Tb activated YAG phosphor)) and Y<SB>2</SB>SiO<SB>5</SB>:Tb (Tb activated yttrium silicate phosphor) can be used as oxide phosphors activated by rare earth element terbium (Tb) as a light emitting center.
