摘要： One selection period S and display cycles Td of a number corresponding to a maximum gradation level are allotted in one field, and the display cycle Td is composed of an unselection period U and a reset period R to perform the following control. A row electrode-driving circuit is used to output a selection pulse Ps during the selection period S, output an unselection signal Su during the unselection period U in the display cycle Td, and output a reset pulse Pr during the reset period R. A column electrode-driving circuit is used to output an ON signal during a light emission maintenance period, and output an OFF signal at least at an end timing of the light emission maintenance period, of the period other than the light emission maintenance period. Accordingly, it is possible to effectively reduce the electric power consumption, and it is possible to achieve the high brightness.

摘要： 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.

摘要： Assuming that a display period for one image is one field, a light source turn on period and a light source turn off period are set for the one field. An overall bending displacement period for making bending displacement of all actuator elements is set within the light source turn off period. A gradational display period for performing substantial gradational display and a reset period for resetting the bending displacement of all of the actuator elements are set within the light source turn on period. Subfields of a number corresponding to the maximum gradation level are set within the gradational display period. Timing control is performed so that all row selection is completed within each of the subfields. Accordingly, the gradation level is advantageously extended when a relationship of Tr>>Tf is given between a light-emitting rising time Tr of the picture element and a quenching falling time Tf of the picture element.

摘要： A light source has a light emission section comprising a two-dimensional array of electron emitters and a drive circuit for applying a drive voltage to each of the electron emitters of the light emission section. The drive circuit applies the drive voltage between upper and lower electrodes of each of the electron emitters based on a control signal representative of turn-on/turn-off from an external source (a turn-on/turn-off switch or the like), for thereby controlling each of the electron emitters. Each of the electron emitters has a plate-like emitter, an upper electrode disposed on a face side of the emitter, and a lower electrode disposed on a reverse side of the emitter.

摘要： An electron-emitting apparatus includes an emitter section made of a dielectric material, lower electrodes, upper electrodes having micro through holes, insulating layers disposed on the upper surface of the emitter section and between the adjacent upper electrodes, and focusing electrodes to which a predetermine potential is applied and which are disposed on the insulating layers. The electron-emitting apparatus applies a negative potential to the upper electrode to accumulate electrons in the emitter section and then applies a positive potential to the upper electrode. As a result, the polarization of the emitter section is reversed, and the accumulated electrons are emitted through the micro through holes in the upper electrodes by Coulomb repulsion. Owing to electric fields generated by the focusing electrodes, the emitted electrons travel in the upward direction of the upper electrode without spreading into a shape of a cone.
