摘要： One image is displayed in a period as one frame, which includes one charge accumulation period and one light emission period. In the charge accumulation period, all electron emitters are scanned, and voltages depending on the luminance levels of corresponding pixels are applied to the electron emitters which correspond to pixels to be turned on (to emit light), to accumulate charges (electrons) in amounts depending on the luminance levels of corresponding pixels in the electron emitters which correspond to pixels to be turned on. In the next light emission period, a constant voltage is applied to all the electron emitters to emit electrons in amounts depending on the luminance levels of corresponding pixels from the electron emitters which correspond to pixels to be turned on, thereby emitting light from the pixels to be turned on.

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.
