Abstract
A method for producing a display with a diffraction grating pattern comprising the steps of reading image data, assigning color for light exposure and moving a slit of an optical system to a position corresponding to the assigned color, moving an origin of an X-Y stage and setting initial data of the assigned color, reading data of an assigned address of the image data and opening a shutter of the optical system for light exposure when data of the assigned color exists, moving the X-Y stage to increase the address by one and repeating the data-reading and shutter-opening step until no further data exists, and changing the assigned color and repeating the above sequence of steps until no further color exists.
