透明液晶显示器色度特性研究 总被引:2,自引:0,他引:2
透明显示器适用于建筑物窗户、汽车车窗与商店橱窗等多种应用,除了原有的透明显示功能以外,还具有未来可能作为信息显示器的发展潜力,因而备受市场关注.但是目前厂商开发的重点仅集中在如何提高透明液晶面板的全光透过率,而对其色度特性研究却很少,导致在实际应用上全光透光率高的产品,其背后物品的色彩显示并不准确,应用效果不理想.在本文中,我们采用本公司量产的315UV2A透明液晶面板,对不同颜色光线通过透明显示器时的色度坐标偏移情况进行研究,确定了透明显示器对色度的影响. 相似文献

A full-color matrix liquid-crystal display panel with color stripe layers of red, green, and blue on theY -electrodes is proposed. The color stripe layers of 300-µm pitch are made by photolithography. The color purities of greenish, bluish, and purplish colors obtained by the liquid-crystal display panel are as good as those of typical printed inks, while those of yellowish and reddish colors are poor at present. In addition, effects of the color layers on the display properties are discussed. 相似文献

Plasma display panel (PDP) structure has been investigated to develop a 21-in-diagonal color plasma display with a high-resolution of 0.22-mm subpixel pitch. To realize a high-resolution display, a stripe alignment of three primary color elements such as red, blue, and green, was introduced. Four kinds of panel structures are compared and finally stripe rib and stripe phosphor structures were introduced for the three electrode surface discharge plasma display. The 21-in-plasma display developed with the structure has firstly been put into the market with sufficient performance, such as a wide operating voltage margin, a high luminance, and a wide viewing angle of more than 60 V, 200 cd/m2 , and 160°, respectively 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

Segment-type, twisted nematic liquid-crystal panels with finely striped, two-color filters within the panel are discussed. The panel has a color filter-on-indium tin oxide structure. Two types of printed filter (an offset-printed (OP) filter and a screen-printed (SP) filter) were subjected to heat treatment and evaluated. It was found that an SP filter of about 0.3 μm has less effect on the operating voltage and availability for multiplexed drive than an OP filter of about 1 μm in thickness with the same color density. The test results for panel reliability for automotive use are given. The panels can digitally display a vehicle's speed, fuel level and engine revolutions in bargraph format with good legibility using three colors 相似文献
