Japanese Patent JP2616918
Kind Code:
B2
Abstract:
PURPOSE:To obtain a device that can be made plane with electric field effect type electron emitting elements by illuminating a fluorescent section with electrons emitted from electrodes having peak sections. CONSTITUTION:Multiple core type bases 2 are formed on an oxidized substrate 1, monocrystals are grown centering its single core, and an electrode 7 with the desired size and having a nearly conical peak section is formed to obtain an electron emitting section. R, G, B phosphors are coated on the electrode 7 in three columns by three lines to form a unit fluorescent region 9, many fluorescent regions are provided on a fluorescent section 8, and each region 9 faces the electrode 7. 0V is applied in sequence to wirings 101-104 in line, transistors are connected to matrix-shaped extracting electrodes 31-34 for each wiring, the voltage is applied at the desired timing, and electrons are emitted from an optional electrode. These emitted electrons pass the center of electrodes 41, 43 and 42, 44 and are radiated to the region 9. At this time, electrons are deflected and controlled in the Y direction and the X direction.
