Abstract
During each of frame periods, an image including gradation information is displayed at once on a display screen. Electrons are emitted in a second stage from all the pixels, independent of row scanning, separately from a first stage based on the row scanning. A display has a plurality of electron emitters arrayed in association with a plurality of pixels, and the image is displayed by electrons emitted from electron emitters. In each of the electron emitters, electrons are emitted from a first electrode toward an emitter to charge the emitter in the first stage, and the electrons are emitted from the emitter in the second stage.

- 1. A display device displaying an image per frame period, wherein said image is displayed at once on a display screen during each of said frame periods, said image including gradation information.
- 4. A display device including a plurality of pixels, said display device displaying an image by light emission from phosphors, wherein said phosphors emit light by electron beams thereby emitting light from said pixels such that desired luminance is obtained, all of said pixels emit light at once for a predetermined light emission time, and each of said electron beams has a current density lower than a value at which said light emission from said phosphors is saturated.
