“…A figure combining a semicircle and a straight line was observed. In the case of a general liquid crystal cell, the equivalent circuit is represented as a parallel circuit of a capacitor and a resistor as illustrated in Figure 9(a) [11]. When this circuit is represented by a vector locus, only a semicircle is drawn.…”

Photoelectric properties and drive characteristics of guest-host (GH)-type liquid crystal cells with yellow, magenta, cyan, green, and gray colors using 4-cyano-4'-pentylbiphenyl (5CB) and three diazo-based dichroic dyes were systematically investigated in different driving modes. The dichroic dyes have structures similar to 5CB; therefore, they uniformly mixed and dispersed into the liquid crystal matrix. The green and gray colors were obtained by mixing appropriate ratios of two or more dyes. Impedance of the GH cells decreased upon the incorporation of the dyes into 5CB. However, the photoelectric properties and drive characteristics of the liquid crystal cells were not altered after the inclusion of the dye. In particular, the alignment of the molecules strongly depended on the cell structure. The GH cells in twisted nematic mode exhibited a low driving voltage of approximately 1.5 V.

“…It has been more than 40 years since the first thin film transistor (TFT) liquid crystal display (LCD) was proposed by B. J. Lechner, et al in 1971. [1] In this conventional pixel circuit, only one TFT and one storage capacitor are used in addition to the liquid crystal capacitance.…”

“…More detailed information on various aspects of avalanche-diode performance and state-of-the-art data may be found in several recent review articles [1]- [3]. I t has been found, both theoretically and experimentally, that avalanche diodes may be operated as microwave oscillators and amplifiers in several different modes.…”

Abstrocf-A new reflectivedisplay principle is described. A roughened glass surface wetted with a transparent volatile liquid of the same refractive index as the glass acts as a transparent medium. The electrical heating, via transparent electrodes, of a thin 6lm of liquid adjacent to the roughened surface transforms the glass into a light scattering surface. The fundamental thermal, electrical, and optical characteristics of the display element are reported. Schemes are desmied for building simply constructed flat panel arrays of liquid-vapor display elements. Such displays are capable of gray scale, can be designed to have frame-time or permanent memory, and can be matrix addressed by electronic, thermal, or geometric means.
