A display screen comprises many pixel lamps arrayed uniformly and in a regular pattern. Pixel lamps come in three types (first- to third-color lamps), and image data to be displayed on the screen consist of bit-map type multi-colored data in which one pixel is represented by a set of three-type color data (first- to third-color data). Each color data plane on a bit-map image data plane is divided into many groups each consisting of a plurality of contiguous pixels, each group is correlated to each first color lamp on the display screen, an operation of selecting in a preset sequence first-color data of a plurality of pixels belonging to one group is repeated, and a first-color lamp correlating to each group is emission-driven according to a selected first-color data. (The same steps are followed for second- and third-color lamps).

A method of and system for displaying high-density bit-mapped dot-matrix imaging data on a large-scale low-density dot-matrix display is disclosed. Bit-mapped image data from each of multiple and adjacently oriented dot image data groups is allocated to drive one dot of the aforesaid display. This is done through a process in which a data selection sequence standard is employed to alternately select and extract image data from each of the aforesaid dot image data groups continually and repetitively at high speed, and in which the extracted image data from each dot image group is applied to drive one dot on the display.

A scan type display device has a device body carrying a light emitting cell array, in which a plurality of light emitting cell arrays are aligned on a line, for scanning aerial plane to display a desired image by residual image effect. The light emitting cells are selectively illuminated according to an image data stored in a memory in synchronism with motion of the device body. The display device also has at least one light receiving element provided on the device body in a positional relationship with the light emitting cell array in such a manner that, when an image carrying medium containing an image to be sampled is placed in close proximity to the light emitting cell array in opposition and the light emitting cells in the light emitting cell array are selectively illuminated, a reflected light from the image carrying medium is received by the light receiving element for sampling the image on the image carrying medium. When an image carrying medium is placed in close proximity to the light emitting cell array in opposition, each individual light emitting cell is illuminated in order for locally irradiating light on the image carrying medium for reading output the light receiving element for sampling image data of a linear image fraction, and by relatively shifting the image carrying medium and the light emitting array for repeating sampling of image data for other linear image fraction to establish an image data of the two-dimensional image.
