Abstract: A color display device has an evacuated vessel accommodating at least an electron-beam generating source in which a plurality of surface-conduction electron emitting devices are arrayed on a substrate, and phosphors for the three primary colors red, green and blue for emitting light in response to being irradiated with electron beams from the electron-beam generating source. A modulator is provided to modulate the electron beams, which irradiate the phosphors, based upon an image signal, the modulator having gamma -corrector for subjecting the image signal to a gamma correction. The modulator modulates the electron beams based upon the image signal corrected in advance by the gamma -corrector.

Abstract: This invention relates to an electron source and an image forming apparatus each of which particularly comprises a surface conduction type electron emitting element as an electron emitting element, a method of manufacturing an electron source and an image forming apparatus, in which the energization forming treatment step of the surface conduction type electron emitting element is performed by applying a voltage to an electron emitting portion formation thin film via a nonlinear element connected in series with the thin film and having nonlinear voltage/current characteristics, an electron source and an image forming apparatus in each of which the nonlinear element is connected in series with the surface conduction type electron emitting element, and a method of driving the same. Typical nonlinear elements include rectification and diode elements. In addition an element for removing a noise component superposed on the input signal is connected in series with surface conduction type electron emitting element.
