Fluorescent display device and manufacturing method therefor

摘要

A fluorescent display device includes a housing having with a glass substrate and a circuit board adhered to the inner surface of the glass substrate of the housing. The circuit board includes an anode formed of multiple anode conductors, control elements for controlling the anode conductors and a phosphor layer formed on the anode conductors. The fluorescent display further includes an electron source formed above the anode in the housing, from which electrons are bombarded to the phosphor layer corresponding to the anode conductors selected by the control elements so that a desired display can be obtained. An aluminum thin film with the aluminum area ratio within a range from 30 to 60% is formed on the inner surface of the glass substrate and the circuit board is fixed to the aluminum thin film via a die-bond material.
