摘要

An arrangement for displaying color images to produce colored images from first and second registers, comprising a viewing screen comprising particles of a first phosphor that emit light of a first color when excited by an electron beam that they have a velocity of at least a first predetermined value, and particles of a second phosphorus each of which has a surface layer which constitutes a partial barrier for the electrons, the particles of the second phosphor having a higher electron excitation threshold that of said particles of the first phosphor, said particles of the second phosphor emit light of a second color substantially complementary to said first color when excited by a beam of electrons having a velocity of at least a second predetermined value that is greater than said first value, means to generate a first electron beam that has nen a speed of said first predetermined value and an intensity modulated according to said first record to cause said particles of the first phosphor to emit light of said first color and produce an image in said first color corresponding to said first register and means to generate a second beam of electrons having a velocity of said second predetermined value and an intensity modulated according to said second register to thereby make the particles of said first and said second phosphor emit substantially achromatic light and produce an image in substantially achromatic light corresponding to said second record.
