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.

A display system for depicting a moving image of a graphic of the type herein defined comprising: (i) a display means having a display area and an activating means; said display area being defined by an array of first and second groups of elements arranged in the form of a matrix having a series of rows and columns, each element of said first and second groups forming a cell of the matrix, said rows being arranged parallel to the intended direction of movement of said image and said columns being arranged orthogonal to said intended direction of movement; and wherein said element of said first and second groups is an image source operable to emit an image, said image being a portion of said graphic on activation thereof, said first group of elements located in selected rows of said matrix, wherein successive elements of said first group in the same row are spaced apart by one or more columns having a group of coplanar, non-image source elements in said same row which do not emit a portion of said graphic, and a second group of elements of similar formation to said first group of elements but located in other selected rows of said matrix, wherein said second group of elements are disposed in interlacing fashion relative to said first group such that one element of said second group is disposed intermediate to a pair of successive elements of said first group in an adjacent row to the row of said one element, and a cell occupied by an image source in one said group of elements partially overlaps with an immediately adjacent cell in the same column, said adjacent cell being defined by a non-image source element disposed in a row of another said group of elements; and said activating means being associated with each of said image sources to activate an image source in response to the generation of a corresponding electrical signal; and (ii) a controller means for generating a set of said electrical signals in sequential groups, each set providing encoded data of a sample portion of said graphic to be represented by one column of said matrix at a prescribed instant, and successive groups of said sets providing further encoded data of successive sample portions of said graphic to be represented by said one column at successive prescribed instants, the period between successive prescribed instants being a display state period of said image, said encoded data being sequentially provided to be represented by successive columns of said matrix at said successive prescribed instants, wherein only those rows of image sources within a column of said matrix are activated for which an electrical signal has been generated in accordance with said encoded data.
