美国等离子体显示板的状况在几个月时间内发生了根本性变化.最近日本厂商对建造等离子体显示器厂作出的坚定承诺,对这种已有32年历史的技术作了充分的肯定.据报道,这一举措已促使美国计算机OEM厂商争先恐后地去寻找本国供应源,唯恐错过这次浪潮.曾任伊利诺斯大学等离子体研究室主任、现任美国Plasmaco公司总经理Larry Weber说,“Plasmaco已与一家世界一流的电子公司签订一项重大的等离子体显示板协议.”美国Photonics Imaging公司总经理PeterFriedman说,有许多大的计算机公司要与他商谈等离子体显示板业务.下一个浪潮是取代阴极射线管(CRT)的大显示板市场.Friedman认为,大型彩色等离子体显示板市场最终将使液晶显示器(LCD)市场相形见细.他说,“第二次平板显示器浪潮的目标将是取代CRT,而且第二次浪潮将比第一次膝上机浪潮更加汹涌.LCD并未取代CRT,却建立了新的市场”. 相似文献

Full color reproduced by white OLED (organic light emitting diodes) coupled with transmission color filters for the application in flat panel display was analyzed theoretically and experimentally. A white emitter made up of three primary emission peaks was found to be superior to a white emitter made up of complementary colors, i.e. two emission peaks. However, though the full color reproduction by white emitter possesses the merit of manufacturing simplicity, it is much worse than the color reproduction by three individual primary color sub-pixels, in terms of power efficiency and the power consumption. Adjusted to the same external quantum efficiency, the full color pixel made of three primary color sub-pixels is 10 times more efficient than that made of white emitter coupled with color filters. 相似文献

With the objective of realizing a luminescent gas-discharge panel for color picture display, we made a comprehensive study of the various gas-discharge cells, including a planar positive-column (PPC) cell of our own design, with emphasis on the geometry of the gas discharge. First, ultraviolet spectroscopic measurements were performed on the PPC cell and on a conventional longitudinal cell filled with rare-gas mixtures. Next, the luminance characteristics of both types of phosphor-coated cells having various dimensions were examined from many points of view. As a result, fundamental differences in the luminescence characteristics between the positive column and the negative glow were revealed, demonstrating the excellence of the PPC cell for a luminescent color display. Furthermore, detailed measurements of luminance, luminous efficiency, and chromaticity were made for PPC cells coated with phosphors for the three primaries, giving basic data for the design of an actual display panel. 相似文献

The dc gas-discharge display panel introduced combines internal memory characteristics with the positive column discharge, yielding high luminance and efficiency. The nature of the memory function is based on shifts in the discharge path between display and auxiliary discharge spaces. Because of this operating principle, the panel has a switching time as fast as 10 µs, enabling use of the panel for real-time color TV displays with 64 gray levels. 相似文献
