摘要： A sub-twisted nematic liquid crystal display (SBTN-LCD) device (30) having a liquid crystal layer (34) characterized as a polarization rotator below an optical threshold voltage, a half-wavelength plate at approximately a saturation voltage, and a transparent layer above the saturation voltage. The twist angle of the liquid crystal layer is between 46.degree.-89.degree., preferably about 55.degree.. The product of the birefringence of the liquid crystal and the thickness of the liquid crystal layer (.DELTA.nd) is in the range of 0.35-0.70 .mu.m, and preferably about 0.52 .mu.m for the 55.degree. twist. One polarizing layer (42) is applied to the liquid crystal device with the polarization direction either parallel or perpendicular to the immediately neighboring liquid crystal director. Further, the performance of the SBTN-LCD is dependent upon the parameters of the liquid crystal material, such as the elastic constants.

摘要： A dual-frequency bistable liquid crystal display and the liquid crystal mixture thereof includes liquid crystal cell filled with a liquid crystal mixture which contains dual-frequency liquid crystal, chiral compound, and nematic liquid crystal mixture. The liquid crystal mixture has the characteristics of both the dual-frequency liquid crystal and cholesteric liquid crystal. The dual-frequency bistable liquid crystal display is driven in a frequency modulation mode and can be switched between two optical states by taking advantage of the dielectric anisotropy of the liquid crystal, which results in a short switching time and sharp contrast between two optical states. Furthermore, the maintaining of the two optical states requires no voltage, which does not require the use of a high voltage to destabilize the helical structure of the cholesteric liquid crystal, and does not have to go through a metastable stage. Hence, power consumption and switching time are reduced.

摘要： A color display that includes an array of pixels having a top side and an opposite bottom side. Each pixel includes a material having a first optical state exhibiting birefringence and a second optical state different from the first optical state. Each pixel also includes an element capable of driving the pixel to a selected one of the first optical state or the second optical state. A first selected group of pixels of the array has a first pair of axes of optical birefringence when each pixel of the first selected group is in the first optical state and at least a second selected group of pixels of the array has a second pair of axes of optical birefringence, different from the first pair of axes of optical birefringence, when each pixel of the second selected group is in the first optical state. A reflective layer is disposed adjacent the bottom side and a polarizing layer, having a predetermined polarity orientation, is disposed adjacent the top side. The first pair of axes of optical birefringence are oriented relative to the polarity orientation so that when a first selected pixel of the first selected group of pixels is in the first optical state, light entering the first selected pixel through the polarizing layer, reflecting from the reflective layer and exiting the first selected pixel through the polarizing layer appears as a first color. Also, when the first selected pixel is in the second optical state, light exiting the first selected pixel through the polarizing layer does not appear as the first color. The second pair of axes of optical birefringence are oriented relative to the polarity orientation so that when a second selected pixel of the second selected group of pixels is in the first optical state, light entering the second selected pixel through the polarizing layer, reflecting from the reflective layer and exiting the second selected pixel through the polarizing layer appears as a second color, different from the first color. Similarly, when the second selected pixel is in the second optical state, light exiting the second selected pixel through the polarizing layer does not appear as the second color.
