ABSTRACT:
A matrixed display device comprises a plurality of monochrome optical bodies arranged in a matrix of intersecting horizontal rows and vertical columns and an optical bandpass filter element associated with each such body. The filter elements are in first, second and third arrays, passing red light, green light and blue light respectively. In each row and column of the matrix, a filter element of one of the three arrays is located between filter elements of the other two arrays. With this arrangement of filter elements, a color pixel can be formed by selectively stimulating first and second monochrome optical bodies that are adjacent each other in a first row of the matrix and a third monochrome optical body that is in a row adjacent the first row and is in the same column as one of the first and second optical bodies.
