Abstract
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 a head of 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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
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 (38) of an optical system to a position corresponding to said assigned color; moving an origin of an X-Y stage (20) and setting a head of data of said assigned color; reading data of an assigned address of said image data and opening a shutter (48) of said optical system for light exposure when data of said assigned color exists; moving said X-Y stage to increase said address by one and repeating said data-reading and shutter-opening step until no further data exists; and changing said assigned color and repeating the above sequence of steps until no further color exists.
Claim 2
Independent Claim
126 words
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 (38) of an optical system to a position corresponding to said assigned color; moving an origin of an X-Y stage (20) and setting a head of data of said assigned color; reading data of an assigned address of said image data and opening a shutter (48) of said optical system for light exposure when data of said assigned color exists; moving said X-Y stage to increase said address by one and repeating said data-reading and shutter-opening step until no further data exists; and changing said assigned color and repeating the above sequence of steps until no further color exists.
Claim 3
Independent Claim
107 words
A method for producing a display with a diffraction grating pattern, comprising the steps of: reading image data; inputting visual field data to a computer (66); moving an origin of an X-Y stage (20); inputting an initial value of dot data: determining a pitch, direction and curvature of a diffraction grating based on said dot data; moving said X-Y stage to a position corresponding to said dot data based on the dot data; delineating said diffraction grating using an electron beam exposing device; and increasing an address corresponding to said dot data by one and repeating the above sequence of steps starting from said initial-value inputting step.
