PIXEL ALIGNING METHOD FOR PROJECTION DISPLAY DEVICE, AND CHART USING THEREFOR

摘要

PROBLEM TO BE SOLVED: To obtain a projected image without misalignment. SOLUTION: When an A chart has a 1st pattern obtained by arranging each pixel array consisting of a plurality of vertically continuous pixels horizontally with the interval of one pixel respectively and a 2nd pattern obtained by arranging each pixel array consisting of a plurality of horizontally continuous pixels horizontally with the interval of one pixel respectively and a B chart is obtained by arranging a plurality of vertically continuous pixel arrays and a plurality of horizontally continuous pixel array in an almost cross shape, a chart projected on the screen is one among combinations of the respective charts of A and A, A and B or B and B in a 1st light bulb among three light bulbs for colored light, one among combinations other than charts of the 1st light bulb in the 2nd light bulb, and one other than the charts of the 1st and 2nd bulbs in the 3rd light bulbs.
