Patent ID: 7110011

Claim:
A monochromatic image display system comprising: a display device comprising a plurality of picture elements, each picture element comprising a series of spatially adjacent cells, arranged in a linear manner, each cell emitting light in a same color and expressing tones in three or more levels; and a cell signal generating means which generates, based on a monochromatic image signal indicating an output luminance of each picture element of a monochromatic image, a cell signal for each spatially adjacent cell of a respective picture element of said display device, said cell signal determining an output tone level of the cell, so that an average of the output luminance of all the cells within each respective picture element correspond to an output luminance of the respective picture element, wherein each respective picture element of said display device corresponds to a picture element of said monochromatic image, and wherein the output luminance of the plurality of picture elements of said display device express said monochromatic image.
