FRONT LUMINOUS VACUUM FLUORESCENT DISPLAY

Front Luminous Vacuum Fluorescent Display is a variation of the vacuum fluorescent display technology which offers improvements in the areas of visibility, viewing angle, operating temperature range, and life. This technology has been discussed since the invention of the conventional vacuum fluorescent display (VFD) because of its structural similarity to the CRT. Today, Front Luminous Vacuum Fluorescent Display (FLVFD) technology is becoming a production reality. Since July, 1980, the following areas have been studied and evaluated to bring FLVFD to the state of commercialization: (1) Design study and trial production; (2) Development of the transmissive anode and wiring pattern forming technology; (3) Development of the phosphor coating technique; (4) Study of the visual recognition characteristics; and (5) Reliability evaluation.
