PCT No. PCT/AU85/00205 Sec. 371 Date Jun. 29, 1987 Sec. 102(e) Date Jun. 29, 1987 PCT Filed Aug. 29, 1985 PCT Pub. No. WO87/01493 PCT Pub. Date Mar. 12, 1987.A display system is disclosed for depicting a moving image of a graphic representation of a sequence of, for example, letters, words, symbols or artwork. The system comprises a display area defined by an array of light emitting diodes (LED's) which form a matrix having a series of rows and columns. The LED's are arranged in rows parallel to the intended direction of movement of an image and the columns are arranged orthogonal to the intended direction of movement. The LED's are further arranged in first and second groups in an interlacing fashion, wherein successive LED's of the first and second groups are spaced apart by one or more columns which do not contain LED's. A controller is further included for generating a plurality of electrical signals in sequential groups, each such group of signals representing encoded data of a sample portion of the graphic to be represented by one column of the matrix at a prescribed instant, and successive groups of the sets of data providing further encoded data of successive sample portions of the graphic to be represented by a column and successive prescribed instants. The system is capable of displaying high-definition graphics with only a fraction of the picture elements necessary in prior art systems, and yet which produces an image that does not tend to break up into momentary fragments, jitter, or wobble.
