摘要： A method for alignment of a homeotropic liquid crystal cell by doping a percentage of a positive Δε (dielectric anisotropy), neutral (Δε approximately 0), or negative Δε liquid crystal material, a high contrast ratio homeotropic alignment of difluoro compounds or mixtures is achieved, independent of operating temperature. Without special requirement on alignment layers, rubbing methods or pretilt angles, the uniform aligned homeotropic liquid crystal cell results even at high temperature and the physical properties, such as the birefringence and viscosity, of the liquid crystal mixtures are improved. In an embodiment the method the homeotropic vertically aligned nematic liquid crystal cells are used in the production of high contrast microdisplays.

摘要： A device structure for single cell gap reflective and transflective liquid crystal displays (TF-LCDs). For an entirely reflective LCD, the imbedded wire-grid polarizer (WGP) serves as a polarization-dependent for the ambient light. For a transflective TF-LCD, the WGP only covers the reflective pixels. The disclosure also includes a method of using single cell gap liquid crystal displays (LCDs) without phase retardation films by providing a single cell gap LCD having reflective pixels and transmissive pixels, covering solely the reflective pixels, with at least one of: a wire grid polarizer and a broadband cholesteric reflector (BCR), reflecting ambient light off the reflective pixels; and passing back light through the transmissive pixels whereby the cell gap LCD obtains high contrast ratios without using phase retardation films.

摘要： An optical display employs a liquid crystal cell with a d.DELTA.n/.lambda. of approximately 0.2-0.8, allowing the cell's optical transmissivity to be modulated by an applied electric field through a dominant non-polarization rotation effect. For visible wavelengths, d.DELTA.n is approximately 0.1-0.4 microns, with a preferred value of about 0.25 microns. Applications include a reflective projection display in which input light is polarized at a greater than 0.degree. and less than 90.degree. angle, preferably about 20.degree., to the input LC directors of a twisted nematic cell; a reflective direct view system in which a quarter-wave plate is substituted for a polarization analyzer; and both a reflective and a transmissive guest-host system in which optical absorption by dye molecules is the dominant modulation mechanism.

摘要： A transflective display includes pixels each including a reflective (R) sub-pixel, a transmissive (T) sub-pixel, and electrodes having features to cause multiple domains to form in a liquid crystal layer of the R sub-pixel and the T sub-pixel. The electrodes in the R sub-pixels have features that are different from features of the electrodes in the T sub-pixel to cause the liquid crystal layer in the R sub-pixel to have an optical phase retardation that is between 20% to 80% of an optical phase retardation of the liquid crystal layer in the T sub-pixel. The R sub-pixel and the T sub-pixel have substantially the same cell gap and are driven by the same pixel voltage.

摘要： A liquid crystal display includes a first alignment film having a first alignment direction, a second alignment film having a second alignment direction, and a liquid crystal layer having liquid crystal molecules between the first and second alignment films. The liquid crystal layer is doped with a chiral material that tends to induce a first twist in directors of the liquid crystal molecules when an electric field is applied to the liquid crystal layer. The first and second alignment films have orientations that tends to induce a second twist in the directors when an electric field is applied to the liquid crystal layer, in which the direction of the first twist is different from the direction of the second twist.
