    摘要: A PDP driving method for more reliably lighting cells that should be lit has been disclosed. The pulse duration of a scanning pulse can be varied depending on a scan line. The pulse duration of a scanning pulse to be applied to a scan line, to which numerous cells each having a high probability of becoming a flickering missing point because a priming effect is unavailable or small are connected, is made longer than that of a scanning pulse to be applied to the other scan lines. When a cell connected to the same address line and to an immediately preceding scan line or a scan line preceding the immediately preceding scan line is unlit, the pulse duration of a scanning pulse to be applied to a cell concerned is made longer. When a whole panel is noted, a scanning pulse having a long pulse duration is applied at least to the first scan bus line. If possible, the scanning pulse having a long pulse duration is applied to the second and third scan lines. As for the other scan lines, since they are influenced by display data, it is judged on the basis of display data to be displayed during the next cycle prior to the next cycle if each cell has a high probability of an addressing discharge failure.

    摘要: A triple-electrode planar display capable of achieving further power saving has been disclosed. A drive unit is dedicated to a planar display having a display panel in which cells being arranged in the form of a matrix and having a memory function and discharge glow function are formed, in which one of each pair of electrodes on the same substrate which are responsible for discharge glow is a common electrode connected in common. The drive unit includes a common electrode drive circuit for applying an alternating voltage to the common electrode, and a power save circuit that when the common electrode is changed from a high potential to a low potential, restores and accumulates power applied to the common electrode, and that when the common electrode is changed from the high potential to the low potential, applies accumulated power to the common electrode. The power save circuit includes a restoration channel that includes a capacitive element and inductance element and that restores power, and an application channel that includes an inductance element and that applies accumulated power to the common electrode.

    摘要: There is provided a plasma display device capable of high luminous efficacy and stable driving for displaying images at various image display load factors. The plasma display device performs the sustain discharge for a light-emission display, and is configured to apply a sustain pulse voltage between a sustain electrode pair in a respective one of the plural discharge cells to generate a sustain discharge in a respective one of the following operating modes selected based upon use of the plasma display device: (a) generating a pre-discharge and then a main discharge; (b) generating a main discharge without a pre-discharge preceding the main discharge; and (c) switching between the mode (a) and the mode (b). The sustain voltage waveforms are used which compensate for an increase in voltage drop due to an increase in discharge current when the image display load factor is excessively increased.

    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.
