Display devices are described which include at least one positive and at least one negative electrode and an electrochemical solution containing a suitable organic solvent, an active material containing species which change color under the influence of an electrical signal, and an electrolyte, the improvement residing in the use of organic quinones or diodes as the said active material. These devices exhibit high optical contrast, pleasing and striking colors and unusually low power consumption. Particularly advantageous is the fact that these display devices may exhibit non-linear behavior (sharp thresholds) which permit multiplexing. This is highly advantageous in display device applications.
所述显示装置包括至少一个正电极和至少一个负电极,以及含有适当有机溶剂的电
化学溶液、含有在电信号影响下会变色的物质的活性材料和电解液,改进之处在于使用有机醌或二极管作为上述活性材料。这些装置具有光学对比度高、色彩悦目醒目、功耗极低的特点。特别有利的是,这些显示器件可以表现出非线性行为(尖锐的阈值),从而允许多路复用。这在显示设备应用中非常有利。
