THIN-FILM HIGH-CONTRAST FLUORESCENT DISPLAY UNIT AND ITS MANUFACTURING PROCESS Russian patent published in 1998 - IPC

FIELD: fluorescent display panels. SUBSTANCE: display unit has fluorescent panel incorporating glass substrate with electrodes deposited onto it, first and second insulating layers with phosphor layer between them, and electrodes deposited on second insulating layer, as well as annular filtering polarizer mounted in front of glass substrate. Fluorescent panel manufacturing process is characterized in that phosphor is deposited at rate not exceeding 50 angstrom per second by thermal evaporation. EFFECT: reduced light reflection from environment and improved contrast enabling displayed image viewing at sunshine. 4 cl, 4 dwg
