Latest Patents

Hirai's patent, titled "Low voltage electron beam display apparatus having brightness increased," focuses on manufacturing a low voltage electron beam excitation phosphor display apparatus. This apparatus includes an anode enclosed in a vacuum chamber, a phosphor film formed on the anode's principal surface, and a cathode positioned opposite the phosphor film. The invention involves preparing a phosphor that consists of an oxisulfide and an oxide, which is removed to produce an oxide-removed phosphor. The process includes coating a paste made from the oxide-removed phosphor, a conductive material, and an autolytic type binder on the anode's surface. The binder is then heated in a non-oxidizing atmosphere to form the phosphor film, ultimately leading to the creation of the display apparatus.
