A laser-written moving image display apparatus comprising a source capable of producing an ultra-violet laser beam, a screen comprising an aligned arrangement of first, second and third types of phosphors, said first type of phosphor fluorescing so as to emit visible red light when impinged upon directly by said laser beam, said second type of phosphor fluorescing so as to emit visible green light when impinged upon directly by said laser beam and said third type of phosphor fluorescing so as to emit visible blue light when impinged on directly by said laser beam, deflector means for deflecting said laser beam so as to cause said beam to scan said screen and control means for controlling the intensity of the laser beam and for synchronising signals transmitted to said laser and to said deflection means whereby said laser simultaneously addresses said phosphor and provides the energy for illumination. |
