DUAL SIDE VACUUM FLUORESCENT DISPLAY INCLUDING REAR SUBSTRATE ON WHICH BRAND NAME OR LOGOS ARE FORMED AND DISPLAYED BY LIGHT

摘要

PURPOSE: A dual side vacuum fluorescent display is provided to form brand name or logos on a rear substrate, and display the brand name or logos by emitting light from phosphor layers. CONSTITUTION: A dual side vacuum fluorescent display comprises a front display unit, a rear display unit, a plurality of line cathodes, a first lead unit(606), and a second lead unit. The front display unit includes a first conductive layer formed into a predetermined information pattern on a front substrate(600), a first phosphor layer deposited on the first conductive layer, and a first grid electrode(608) formed into a predetermined pattern on the first conductive layer. The rear display unit includes a second conductive layer formed into a predetermined log pattern all over a rear substrate(620), and a second phosphor layer deposited on the second conductive layer. The line cathodes are arranged between the front display unit and the rear display unit. The first lead unit drives the front display unit, and the second lead unit drives the rear display unit.
