Abstract:
An improved vacuum fluorescence display (VFD) (10) that is less expensive to produce and more rugged than currently available VFDs. The display includes metal side walls (16) and fluorescent material carried on one or more silicon wafers (20). A ceramic, layerable insulating material is employed as the substrate (12) on which the wafer or wafers are mounted. In another embodiment of the current invention, a chemical getter (28) is incorporated into a recess (30) formed in the ceramic substrate. The getter is positioned underneath the back side of the phosphor screen so as to significantly reduce contamination of the screen by material sputtered off of the surface of the getter.
Abstract:
A field emission display which includes thin film resistors disposed between the electron-emitting elements of a cathode and a conductive support which provides electrical connection to said electron-emitting element through said thin film.
Abstract:
A flat panel display is described. The flat panel display includes a matrix of light-emitting diodes which are driven by thin film field effect transistor circuits in which the channel electrodes of the filed effect transistors are cadmium selenide or cadmium telluride. The cadmium selenide or cadmium telluride contains fluorine ions to enhance the mobility. A non-oxygenated later is applied to the channel electrodes.
