    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： A driving method for a display apparatus produces light emission by applying a sustain discharge pulse repeatedly. A pulse width of the sustain discharge pulse is varied within one subfield and is controlled in accordance with the amount of voltage drop of a sustain discharge voltage. A display apparatus has a display panel section, a data converter, a power supply section, and a sustain discharge pulse control circuit. The data converter receives an image signal and supplies image data suitable for the display apparatus to the display panel section, and the power supply section supplies power to the display panel section. Further, the sustain discharge pulse control circuit varies a pulse width of sustain discharge pulse within one subfield and controls the pulse width of the sustain discharge pulse in accordance with the amount of voltage drop of a sustain discharge voltage.

    摘要： A display method of a plasma display apparatus to which primary color video signals are inputted and which carries out color display by letting phosphors for primary colors emit light is provided. The display method displays the primary color video signals by changing a gray level of an output primary color video signal in accordance with a gray level of an input primary color video signal. When each gray level of the inputted primary color video signals changes from a first value to a second value which is larger than the first value, a gray level of a primary color video signal for a phosphor having the largest influence of luminance saturation properties among the phosphors is increased relative to a gray level of the other primary color video signal.
