    摘要： In a display panel, the luminance and contrast are improved by making a partition semitransparent, which is a constituent element adjacent to a light-emitting section. A visible light incident on the partition proceeds inside the partition while being attenuated at a constant rate. When an external light incident on the partition from the front side is reflected off the bottom surface of the partition and returns to the front side again, the external light reciprocates inside the partition. Since the external light is largely attenuated by the reciprocation, the partition seemingly functions as an optical absorber with respect to the external light. A light emitted by the light-emitting section can transmit through the partition and radiate to the outside from the front side.

    摘要翻译： 在显示面板中，通过使作为与发光部相邻的构成要素的分隔半透明度来提高亮度和对比度。 入射到分区上的可见光在分区内进行，同时以恒定的速率被衰减。 当从前侧入射到隔板上的外部光被从隔板的底面反射出来再次返回到正面时，外部光在隔板内部往复运动。 由于外部光被往复运动大大地衰减，所以分隔似乎作为相对于外部光的光吸收器起作用。 由发光部发射的光可以透过隔板透射从前侧向外部辐射。

    摘要： A plasma display panel has a first substrate, a plurality of address electrodes disposed on the first substrate, a first dielectric layer disposed on the first substrate in covering relation to the address electrodes, a second substrate, a plurality of scan electrodes disposed on the second substrate in a direction transverse to the address electrodes, a second dielectric layer disposed on the second substrate in covering relation to the scan electrodes. The first substrate and the second substrate are disposed in confronting relation to each other with discharge spaces defined therebetween. The first dielectric layer contains electrically conductive particles mixed therewith. The electrically conductive particles make the first dielectric layer electrically conductive in its transverse direction to allow charges stored on the first dielectric layer to leak to the address electrodes for thereby reducing the frequency of random discharges.

    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： A plasma display panel has a front substrate (3) and a back substrate (2) arranged opposed to each other through a discharge space (4). On the back substrate, a fluorescent layer (5) is formed. On the front substrate, display electrodes are formed extending in a horizontal direction, a discharge cell area is demarcated corresponding to the display electrodes, and a plurality of shielding films (13) extending in the horizontal direction are moreover formed at each position which is among the display electrodes and within the discharge cell area. When the distance between the shielding films and the fluorescent layer is set to be D, the width L of a shielding film and the distance S between the shielding films satisfy 0.58≦L≦D and D≦S≦1.73D. This reduces the reflectance ratio of outdoor daylight to improve lighted room contrast.

    摘要： In this PDP apparatus, in a sustain driving circuit device for supplying sustain discharge pulses, an energy recovery circuit has a coil, switches, and diodes, and a Vs clamp circuit has switches. In the energy recovery circuit, the switches are connected to a panel capacitor, and the coil is connected to a power source line with an intermediate potential of Vs, and a clamp diode and a power source connected thereto are connected to a node between the coil and the switch. As a control timing, at a timing of less than π/2 of an LC resonance current cycle, the switch of the energy recovery circuit is turned OFF and then the switch of the Vs clamp circuit is turned ON, thereby performing the Vs clamp.
