摘要： In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.

摘要： An optical filter is provided on the output side of light from plural kinds of cells that output light with colors different from one another. In the optical filter, the penetrable rate of at least a portion of the wavelength band of light output from the cell with the color having highest luminescent intensity is set lower than that of the wavelength band of other kinds of cells. Consequently, the reflectance rate of outer light incident to a display can be reduced. Particularly, in a room environment using artificial lighting, the reflectance rate of outer light can be reduced in the wavelength band of light with relatively high luminescent intensity. Resultingly, bright room contrast can be improved by suppressing the reflection of outer light. Since the penetrable rate of the color with the highest luminescent intensity is reduced, reduction in brightness of the display can be kept to a minimum.
摘要翻译：在从输出彼此不同的颜色的光的多种单元的光的输出侧设置滤光器。在滤光器中，从具有最高发光强度的颜色的单元输出的光的至少一部分的透射率设定为低于其他种类的单元的波长带的透射率。因此，可以减少入射到显示器的外部光的反射率。特别地，在使用人造照明的室内环境中，能够以较高发光强度的光的波长带中的外部光的反射率降低。因此，可以通过抑制外部光的反射来提高亮室对比度。由于降低发光强度最高的颜色的透过率，所以可以将显示器的亮度降低到最低限度。
