摘要： A gas discharge display panel which provides sufficient contrast and good accuracy and is high in yield. When a voltage is applied to auxiliary discharge electrodes, auxiliary discharge occurs in an auxiliary discharge space and excited charged particles communicate with a main discharge space through a priming path made in a discharge space separation bulkhead. In this state, when an alternating voltage is applied between bus electrodes on a front substrate, main discharge occurs in the main discharge space, causing Xe atoms in the sealed gas to generate ultraviolet rays, causing a phosphor to emit light. However, since the auxiliary discharge is shielded by a bulkhead and a barrier rib, the phosphor does not emit light when only auxiliary discharge occurs.

摘要翻译： 气体放电显示面板，其提供足够的对比度和良好的精度并且产量高。 当向辅助放电电极施加电压时，在辅助放电空间中发生辅助放电，并且激发的带电粒子通过在放电空间分隔隔板中形成的起动路径与主放电空间连通。 在这种状态下，当在前基板上的总线电极之间施加交流电压时，在主放电空间发生主放电，导致密封气体中的Xe原子产生紫外线，使荧光体发光。 然而，由于辅助放电由隔板和隔板屏蔽，所以当仅发生辅助放电时，荧光体不发光。

摘要： A display apparatus uses a sub field which illuminates addressed pixels of a display unit to display an image. The display apparatus includes an image signal processing circuit which performs sub field conversion processing on an input image signal, a computational processing circuit which arranges address data of at least one lower sub field of an image displayed on the display unit identical in plural lines, and a drive circuit which addresses and illuminates pixels of the display unit based on the outputs of the input signal processing circuit and the computational processing circuit. An image corresponding to the input image signal is displayed by driving the display unit with the drive circuit when the computational processing circuit performs addressing of the at least one lower sub field simultaneously in plural lines and address periods which select the illuminated pixels of said display unit are shortened.
