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.
摘要翻译：已经公开了用于更可靠地点亮应该点亮的电池的PDP驱动方法。扫描脉冲的脉冲持续时间可以根据扫描线而变化。使得施加到扫描线的扫描脉冲的脉冲持续时间长于扫描线的脉冲持续时间，其中由于启动效应不可用或较小而连接有多个具有高闪烁的丢失点的概率的多个单元比扫描线的脉冲持续时间长应用于其他扫描线。当连接到相同地址线的单元和紧邻在前扫描线之前的紧邻的扫描线或扫描线的单元不亮时，将要施加到相关单元的扫描脉冲的脉冲持续时间更长。当注意到整个面板时，具有长脉冲持续时间的扫描脉冲至少施加到第一扫描总线。如果可能，将具有长脉冲持续时间的扫描脉冲施加到第二扫描线和第三扫描线。对于其他扫描线，由于它们受到显示数据的影响，因此如果每个单元具有寻址放电故障的高概率，则在下一个周期之前的下一个周期中，基于显示数据来判断是否显示。

摘要： An intraframe time-division multiplexing type display device prevents prominent image defects, such as flicker, and affords a high-quality image display. A single frame of an image is displayed while changing a gray-scale level thereof by means of a number of sub-frames, each sub-frame comprising at least an address period and a sustained discharge period; further, the sub-frames have respective, mutually different sustained discharge periods. A gray-scale level adjustment unit arbitrarily sets the selection sequence of each of the number of sub-frames within an individual frame that is to be in a sustained discharge state.

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.

摘要： In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation “MCBCMAX−PSUM×MCBCMAX/PSUM,MAX” is set as the MCBC.
