摘要： A transflective liquid crystal display with uniform cell gap configuration throughout the transmissive and the reflective display region is invented. Mutually complementary common electrode pattern and reflector pattern or mutually complementary ITO pixel electrode pattern and reflector pattern produce an electric field in the transmissive display region that has a uniform longitudinal field and an electric field in the reflective display region that is a fringing field. An initially vertically aligned negative dielectric anisotropic nematic liquid crystal material between the electrodes forms a smaller tilt angle with respect to the substrate normal in the reflective display region while a larger tilt angle with respect to the substrate normal in the transmissive display region. Consequently, the ambient incident light experiences smaller phase retardation in the reflective display region while the light from the backlight source experiences larger phase retardation. Since the ambient light passes through the reflective display region twice while the light from the backlight source passes through the transmissive display region only once, by properly designing the electrodes and the reflector width, the light from both ambient light source and backlight source will experience almost the same phase retardation in both reflective and transmissive display regions. As a result, the electro-optical performance curves of both transmissive display mode and reflective display mode overlap.

摘要： A liquid-filled variable focus lens cell is disclosed. The liquid lens cell consists of four parts: a clear distensible membrane, a transparent wall member, liquid with a fixed volume stored in lens cell chamber, and an annular periphery sealing ring. The inner surfaces of the annular sealing ring are sealed with distensible membrane. The radius of the annular sealing ring is changeable, similar to a conventional iris diaphragm. By tuning the radius of the annular sealing ring, the stored liquid in the lens cell will be redistributed, thus change the curvature of the distensible membrane. Therefore, the liquid lens cell can cause light to converge or diverge. The liquid filled lens can be operated mechanically or automatically.

摘要： Inhomogeneous concentrated polymer network with approximately 90° twisted nematic liquid crystal (TN-LC) is used for fabricating lens and prisms. For forming a positive lens, the approximately 90° TN-LC polymer network concentration can gradually decrease from the center to the side edges. For forming a negative lens, the approximately 90° TN-LC polymer network concentration can gradually increase from the center to the side edges. The lens can be created by ultra violet (UV) light exposure to patterned photo masks. The lens can be tuned by applying voltage above the threshold voltage to the polymer network. The inhomogeneous 90° TN-LC polymer network can also be used in Fresnel lens and prisms. Applications of the invention can be used for micro lens, array, optical communication, micro-optics, adaptive optics and beam steering.

摘要： A high reflection and transmission transflective liquid crystal display (TLCD) that requires only a single cell gap. Instead of reducing the cell gap of the R sub-pixel region, the invention reduces the birefringence change Δn of reflective pixels (R) so that the total retardation change Δnd of R is equal to that of the transmissive pixels (T). This is realized by a partial switching of the pixels of approximately 45 degrees which occurs in the reflective pixel (R) region of the single cell gap by applying fringing fields, generated by a discontinuous electrode, to the molecules in the reflective pixel (R) region of the cell gap.

摘要： A new class of asymmetrical diphenyl-diacetylene liquid crystal compounds exhibit ideal properties for formulating eutectic mixtures suitable for infrared and microwave applications. The new class of liquid crystal compounds comprise asymmetrical nonpolar end groups. These compounds exhibit low melting points, wide nematic temperature range and low heat fusion enthalpy. Eutectic mixtures containing entirely diphenyl-diacetylene homologs using the new compounds have high birefringence, low viscosity and wide nematic range. These unique properties are especially advantageous when these mixtures are used in infrared spatial light modulators, high speed liquid crystal modulators and polymer dispersed liquid crystals shutters. The new asymmetrical diphenyl-diacetylene liquid crystal compounds comprise the following basic structure:R.sub.1 --C.sub.6 H.sub.4 --C.tbd.C--C.tbd.C--C.sub.6 H.sub.4 --R.sub.2wherein R.sub.1 and R.sub.2 are nonpolar end groups and R.sub.1 does not equal R.sub.2. R.sub.1 is selected from the group consisting of alkyl, alkoxy, alkenyl and alkenyloxy end groups and R.sub.2 is selected from the group consisting of alkyl, alkenyl and alkenyloxy. In another embodiment, the liquid crystal compound can comprise an alkenyl group having the general formula C.sub.x H.sub.2x+1 CH.dbd.CH--(CH.sub.2).sub.n-2-x in either the R.sub.1 or R.sub.2 location. Moreover, the liquid crystal compound can comprise such an alkenyl group in both R.sub.1 and R.sub.2 locations, so long as R.sub.1 does not equal R.sub.2. Eutectic mixtures for infrared and microwave applications comprise at least one asymmetrical nonpolar diphenyl diacetylene liquid crystal compound having the general structures described above.
