The “Itron” 256 × 256 Dot Matrix Graphic/Image Vacuum Fluorescent Display

A graphic and image VFD having high dense 256 by 256 dot matrix has been developed. The manufacture of versatile display patterns by thick film printing and producing of glass substrate by thin film technique become possible easily to constitute high dense anode deposit and high quality.

In consequence of new technology establishment, especially the grid construction and improvement of grid formation, the high dense image display was achieved with the exact addressing of each dot. This paper discribes about itself which has the possibility of displaying graphic and image for the automotive application.
