摘要： A method of forming a partition of plasma display panel; and an apparatus therefor. Board (33) to be wrought into a board for plasma display panel is one composed of glass substrate (21) and, superimposed thereon, partition material layer (31) and mask (32a,32b). When the board to be wrought is sandblasted, portion of the layer not covered by the mask is shaved off while only portion of the layer covered by the mask remains and provides a partition. During the sandblasting treatment, the board to be wrought at its both end areas is provided with protective plates of given height (61,62) to thereby prevent excessive shaving of the layer. Eachof the protective plates is composed of main body part (65) and slide contact member (67). The main body part is protected by a member resistant to abrasion so as to avoid shaving by the sandblasting treatment, and the slide contact member is made of a material of low hardness so as to avoid injuring of the board to be wrought.

Consequently, one lateral wall of the first lateral partition wall, the second lateral partition wall, and the other lateral wall of another first lateral partition wall are coupled sequentially by the longitudinal partition wall (29V) and the coupling units are arranged through the gap (30) penetrating in the lateral direction. ® KIPO & WIPO 2009

摘要： A first drive circuit alternately inverts the polarity of voltage applied between first and second electrodes to cause sustain discharge between the first and second electrodes. A second drive circuit applies a pulse to a fourth electrode at the time when the polarity of the voltage applied between the first and second electrodes is inverted, maintain the voltage at the fourth electrode after the pulse application at an offset voltage different from the initial voltage before the pulse is generated by a predetermined value, and then returns the voltage to the initial one. For example, the offset voltage is set to a value between a high-level voltage and low-level voltage applied to the first and second electrodes. With this, during the sustain discharge, the quantity of wall charge accumulated in the fourth electrode can be small, and consequently, the fourth electrode hardly concerns the discharge. As a result, the proportion of high-efficiency long-distance discharge between the first and second electrodes can be increased, and the luminous efficiency can be enhanced.
摘要翻译：第一驱动电路交替地反转施加在第一和第二电极之间的电压的极性，以引起第一和第二电极之间的维持放电。第二驱动电路在施加在第一和第二电极之间的电压的极性反转时向第四电极施加脉冲，在脉冲施加之后保持在与初始电压不同的偏移电压下的第四电极处的电压在脉冲以预定值生成之前，然后将电压返回到初始值。例如，偏移电压被设定为施加到第一和第二电极的高电平电压和低电平电压之间的值。由此，在维持放电期间，积蓄在第四电极中的壁电荷的量可以很小，因此第四电极几乎不涉及放电。结果，可以提高第一和第二电极之间的高效长距离放电的比例，并且可以提高发光效率。

摘要： A discharge is initiated in a cell in which an address discharge is conducted at a first timing T1 in a charge adjustment period (24). Next, at a second timing T2, a discharge is initiated for adjusting a wall charge in a cell where a charge remains therein because the address discharge does not occurred. Thus, some negative charges are formed in an X electrode and a Y electrode, thus preventing a false discharge from occurring in an unselected cell.
