    摘要： A halftone display method utilizes an activation sequence, having a plurality of luminance blocks predefined in each frame or field to display an image and having redundancy, that enables one gray-scale level to be expressed by any one of a plurality of combinations of subframes (luminance blocks). When determining luminance blocks for use to display gray scale of an arbitrary first pixel, the luminance blocks to be used for the first pixel are selected in accordance with a predetermined rule, based on how the luminance blocks are used for a second pixel located in close proximity to the first pixel. In this way, by actively utilizing the redundancy of the activation sequence, the occurrence of moving-image false contours (false color contours) in video can be minimized, and also a motion compensation equalizing pulse method can be effectively applied to further improve the image display quality.

    摘要： In order to operate a discharge apparatus, a first voltage having a first frequency is applied to electrodes. Moreover, a second voltage having a second frequency higher than the first frequency is applied to the first voltage. The waveform of the voltage having the second frequency may be an attenuated one which is synchronized with the first frequency. As a result of this voltage superposition, the electrons, ions, or plasma in the already established discharge fluctuate with the change in the electric field. If the second frequency is selected to be equal or close to the resonance frequency of the electrons, ions, or plasma existing in the already established discharge, there occurs the resonance phenomenon of the electrons, ions, or plasma. This phenomenon raises the temperature of those particles. As a result, the electron temperature approaches to a value preferable for emission of visible light or ultraviolet rays so that the luminous efficiency is improved.
