摘要： The present invention relates to thin film retardation plates, such as cholesteric and A-plate compensators, for improving the viewing angle and contrast of liquid crystal displays. The A-plate is fabricated using a single substrate onto which a layer of polymerizable reactive mesogens (RMs) is solvent cast. Included in the RMs solution is an additive that migrates to the RM/air interface to lower the surface energy and generate an additive-rich surface layer, which in turn lowers the intrinsic tilt angle of the RMs at the air interface to between 25 degrees (25.degree.) and about zero degrees (0.degree.). The solvent is evaporated and the resulting film is polymerized in the liquid crystal phase to permanently orient the liquid crystal. The resulting film may be readily separated from the substrate and shaped into any desired pattern and combined to form novel compensators. In an alternative embodiment, a tilt may be provided by treating the substrate with an oblique alignment layer to form a compensator having a defined splay through the bulk of the thin film.

摘要： An electrical exciting circuit produces a plurality of oscillating electrical excitations, each at an independently controllable frequency. A set of drive electrodes are distributed in an array, and connected so that each receives a respective one of the excitations. A dual frequency liquid crystal (DFLC) material is arranged in the path of a coherent light beam and is disposed in proximity to the set of drive electrodes so as to receive electrical excitations. The DFLC has a dielectric coefficient which varies locally in relation to the frequency of the local electrical excitation received. The voltages and at least two frequencies of the excitations are controlled so as to produce a desired profile of the dielectric coefficient (for at least one polarization) and a corresponding optical phase delay profile for the coherent beam. Preferably, a novel reflective groundplane is included to improve optical reflective efficiency.

摘要： An addressing scheme for use with current-driven emissive displays requires that an N-row by M-column array of pixels be divided into K segments of N/K rows each. One transistor-controlled current driver is provided for each column of pixels within a segment, and all of a segment's current drivers are connected to a respective gate address line. The array is addressed by dividing a frame time into N/K “sub-frame” times. During the first sub-frame time, the current drivers of each segment are turned on in sequence, and the first row of each segment addressed. The remaining rows are addressed in this manner during subsequent sub-frame times. The segmenting and addressing scheme reduces the duty ratio required to drive the array by a factor of K, and reduces the number of transistors required to drive the array by a factor of N/K, when compared with comparably-sized passive matrix and active matrix displays, respectively. Fabrication of the display, and other non-passive matrix displays, is simplified by placing all active components on the back side of the display panel, or on a separate printed-circuit board (PCB) which is interconnected with the pixel array via respective surface bonding pads to form a display. Fabrication is further simplified by combining the current drivers and other drive electronics into application-specific integrated circuits (ASICs).
