Abstract:
An apparatus for displaying a color image, said apparatus comprising:pixel column rendering means for sequentially rendering individual columns of colored pixels, said pixel column rendering means includinga light gate array having a single column of windows, wherein adjacent windows of the column are offset from one another to comprise a first separate portion of windows disposed immediately adjacent to a second separate portion of windows, with top edges of windows of said first portion being aligned, with bottom edges of windows of said second portion;means for providing red light to each of the windows of the light gate array for a first predetermined period;means for providing green light to each of the windows of the light gate array for a second predetermined period, said second predetermined period not simultaneous with said first predetermined period;means for providing blue light to each of the windows of the light gate array for a third predetermined period, said third predetermined period not simultaneous with said first predetermined period or second predetermined period;means for opening pre-selected windows of said light gate array during pre-selected portions of the first, second, and third predetermined periods; andmeans for scanning the pixel column rendering means to generate an image from a plurality of sequentially-rendered individual pixel columns, with each of said individual pixel columns having red, green and blue color components offset from one another, with light pulses corresponding to a single column of pixels being alternatingly transmitted through said first and second portions of windows, and with said scanning means imaging pixels transmitted through said first and second portions of windows into a single column of aligned pixels.
