Abstract

PURPOSE: To increase the degree of freedom in design of structure and shape, etc., of screen and to obtain a high level of brightness by transforming laser beam of a large output to ultra violet ray, and irradiating a phosphor layer on a screen freely scannable with this ultra violet ray.
CONSTITUTION: The laser beam 2a outputted from a laser beam source 2 which is continously oscillated is transformed to, for example, the ultra violet ray 3a of a specified wave length by a transformer 3 consisting of non linear optical crystals, etc. This ultra violet ray 3a is allowed to irradiate freely scannable the phosphor layer 6 of a dot matrix state of the screen 5 at a scanning device 4, and scanning is carried out to plot a desired image. In this way the screen 5 is separated from the scanning device 4. Thus, the degree of freedom in the design in manufacture or shape, etc., of the screen is increased and a high level of brightness in an image can be obtained.
