摘要： A method for driving a PDP is provided which is capable of improving reliability in selective operations, acquiring excellent displaying characteristics, improving contrast, and accommodating a difference in driving characteristics caused by a color to be displayed. If a discharge initiating threshold voltage between surface electrodes is 250 V and the discharge initiating threshold voltage between facing electrodes in a state where lots of activated particles exist in discharging space is 350 V, an ultimate potential of a pre-discharging pulse is set to be 400 V and a electric potential of a pre-discharging pulse is set to be 0 V. When a voltage of the pre-discharging pulse exceeds 250 V being the discharge initiating threshold voltage between surface electrodes, a feeble discharge occurs between surface electrodes. Then, when a voltage of the pre-discharging pulse exceeds 350 V being a discharge initiating voltage between facing electrodes, since lots of activated particles produced by the surface discharge exist in the discharging space, a feeble discharge between facing electrodes occurs.

摘要： A display has circuitry (50) which generates all possible pixel drive signal levels on separate signal level lines. A buffer (54) is associated with each signal level line. The outputs of the buffers are selectably switchable onto the columns. The signal levels for each column are stored in a memory (72) and the buffers are controlled in dependence on the stored signal levels. The response of the buffers is heavily dependent on the output load, and there is a very large variation in the output load of the buffers (54), as a function of the number of columns to which the buffer output is to be provided. The buffers are controlled in dependence on stored signal levels to ensure stability of the buffers for any output load.

摘要： An improved addressing scheme for plasma display panel control comprises partitioning the panel into a number of sections and splitting the addressing period into correspondingly small addressing periods for each section. By varying the time distance between successive addressing periods of the sections from one sub-field to the other, at least for the sub-fields with higher weights, a better spread of the energy input and output of the plasma display panel is achieved and the power supply circuit for the display panel may be constructed with less expensive components.

摘要： A method of driving a plasma display panel showing images having frames composed of odd and even fields. The plasma display panel has scan electrodes and address electrodes perpendicular to the scan electrodes.

摘要： A method for driving a surface-discharge AC (alternating current)-type PDP (Plasma Display Panel) is provided which is capable of shortening a scanning period by securing a wide range in which a voltage to induce sustaining discharge can be set without causing flicker to occur and without causing black luminance to be increased. A sub-field is made up of a resetting period, a scanning period, a wall charge forming period, and a sustaining period. During the scanning period, time interval between scanning pulses is shortened. During the wall charge forming period, each of common electrodes and data electrodes is made to be at a ground potential and a wall charge forming pulse having a same potential as that of a scanning pulse is applied to all scanning electrodes. The time interval between wall charge forming pulses is for example 3 &mgr;sec to 50 &mgr;sec. This causes space charges being left in a display cell to be attracted on each of electrodes, whereby wall charges build up.
摘要翻译：提供了一种用于驱动表面放电AC（交流）型PDP（等离子体显示面板）的方法，其能够通过确保可以设置用于引起持续放电的电压而不引起闪烁的宽范围来缩短扫描周期发生并且不会引起黑亮度增加。子场由复位周期，扫描期间，壁电荷形成期间和持续期间构成。在扫描期间，扫描脉冲之间的时间间隔缩短。在壁电荷形成期间，使公共电极和数据电极各自处于接地电位，并且将具有与扫描脉冲相同的电位的壁电荷形成脉冲施加到所有扫描电极。壁电荷形成脉冲之间的时间间隔例如是3个字节到50个字节。这导致显示单元中剩余的空间电荷被吸引到每个电极上，从而产生壁电荷。
