Flat VFD TV display incorporating MOSFET switching array

A flat TV display panel was fabricated experimentally. It consists of an itegration of 241 × 246 picture elements to produce a picture size of 23 × 23 mm
²
. It operates upon a novel combination of fluorescent display elements and filament cathodes that emit electrons. It has a compact configuration, high light conversion efficiency with its low energy calhodoluminescent phosphor, and an integrated switching array. The operating principle of the new display panel and its experimental results, e.g., 10-fL luminescence at 30-V driving voltage and power consumption of 0.8 W (60 Hz, duty ratio of 1/300), etc. are depicted. In addition, the feasibility of incorporating memory function in the panel is discussed. Experimental results proved that memory function contributed to the reduction of power consumption, enhancement of brightness, improvement of resolution, and facilitation of color display.
