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: An electron source emits electrons as a function of input signals. The electron source comprises a substrate (1), a matrix of wires having m row wires and n column wires laid on the substrate with an insulator layer interposed therebetween, and a plurality of surface-conduction electron-emitting devices each having a pair of electrodes (5,6) and a thin film (4) including an electron emitting region (3) and arranged between the electrodes. The electron-emitting devices are so arranged as to form a matrix with the electrodes connected to the respective row and column wires. Each pixel unit is irradiated by at least two electron beams emitted from the respective electron emitting regions which are juxtaposed with interleaving the higher potential device electrode therebetween and a gap interval W in the juxtaposing direction of which satisfies equation (1) below: K2 x 2H(Vf/Va) ≥ W/2 ≥ K3 x 2H(Vf/Va) where K2 = 1.25 +/- 5.05, K3 = 0.35 +/- 0.05, H is the distance between the surface-conduction electron-emitting devices and the image-forming member, Vf is the voltage applied to the surface-conduction electron-emitting device and Va is the voltage applied to the image-forming member.

Abstract: A method for driving a photo-sensor to produce an improved, stable output which exactly represents the incident light is disclosed. The photo-sensor has a pair of main electrodes found on a semiconductor layer with a photo-sensing area arranged therebetween. A semiconductor layer and an auxiliary electrode are formed on at least the photo-sensing area with an insulating area being interleaved therein. The auxiliary electrode is used for stabilizing the photosensing output and providing a signal proportional to the incident light. The method of driving such a photo-sensor includes applying a bias voltage to the auxiliary electrode in accordance with the carriers carrying a current of the semiconductor layer. A voltage of the same polarity as that of the bias voltage, but smaller in absolute value, is applied to the auxiliary electrode for a predetermine period of time in a non-read period of the photo-sensor to cause a next photo-sensor output to be read while a previous photo-sensor has been erased.
