Abstract:
A method for making a tiled, flat-panel AMLCD display, while maintaining tolerances in three dimensions, the steps comprising:a) providing at least two AMLCD tiles, each of said AMLCD tiles having a front face and containing a plurality of pixels disposed at a predetermined pixel pitch in at least one dimension;b) arranging said AMLCD tiles adjacent one another, said front face down on an optically flat surface with spacers between abutting edges of said AMLCD tiles, said spacers maintaining a predetermined gap therebetween;c) retaining said AMLCD tiles in said arrangement with said front respective faces thereof substantially parallel;d) laminating a back plate and a back, monolithic mask to the rear of said AMLCD tiles while said tiles are being retained, said laminating step permanently retaining said AMLCD tiles in said arrangement, said front faces of said AMLCD tiles being substantially parallel and substantially flush with one another, thereby forming a laminated tile assembly;e) removing said laminated tile assembly from said optically flat surface; andf) laminating a cover plate and a front, monolithic mask to said substantially parallel and flush front faces of said laminated tile assembly.
