Abstract
An optical write element is adapted to be used in an image writing device to form a visual or latent image on a recording medium. The optical write element comprises a rectangular casing having an interior maintained in a high vacuum condition, at least one light-emitting dot array composed of multiple fluorescent light-emitting dots attached along the length of a substrate as part of the casing, at least one cathode placed above the light-emitting dot array, and a pair of shielding members placed over the outside of the light-emitting dot array.
Claims2
An optical write element comprising:
- a rectangular casing having an interior maintained in a high vacuum condition wherein said rectangular casing encloses at least one light-emitting dot array composed of multiple fluorescent light-emitting dots attached along a length of an anode substrate as part of the casing;
- at least one cathode placed above said at least one light-emitting dot array;
- and
- a pair of shielding members extending inside said casing from said anode substrate in a direction of a width of said casing wherein said shielding members are positioned outside of a volume defined between said at least one cathode and said light-emitting dot array.
An optical write element comprising:
- a rectangular casing having an interior maintained in a high-vacuum condition;
- at least one light-emitting dot array composed of multiple fluorescent light-emitting dots attached along the length of a substrate as part of the casing;
- at least one cathode filament placed above said at least one light-emitting dot array;
- an insulating layer surrounding said at least one light-emitting dot array and covering at least a portion of said substrate;
- at least one driver IC element placed on said insulating layer and outside of said at least one light-emitting dot array to drive said at least one light-emitting dot array;
- and
- a pair of shielding members disposed on two peripheral edges of said insulating layer located between said at least one light-emitting dot array and said driver IC element, said shield members extending upwardly beyond a position where said at least one cathode filament is located.
