摘要： A method for synchronizing a light source control signal with modulation of a display includes the steps of receiving a video signal including a synchronization signal (e.g., a Vsync signal) and using the synchronization signal to generate a light source control signals at high and low values. The light source control signal is pulsed between its high and low values between subsequent synchronization signals to cause a light source to produce light pulses at the same time over each frame of the display. Optionally, the low and/or high time periods are adjustable. A novel display driver is also disclosed and includes an input terminal for receiving the synchronization signal, a light source driver for generating the light source control signal in response to the synchronization signal, and an output terminal for providing the light source control signal to a light source control unit.

摘要： A novel projection system includes an illumination source for emitting an illumination beam, a reflective display device for modulating the illumination beam to form a reflected imaging beam, a projection lens group having an optical axis, and a field lens group. The field lens group is de-centered with respect to the optical axis of the projection lens group and is disposed to redirect the illumination beam to illuminate the display device at a non-zero angle of incidence, and to redirect the reflected imaging beam along an optical path parallel to the optical path of the projection lens group. In a particular embodiment the display device is disposed on the optical axis of the projection lens group. In a more particular embodiment, the redirected portion of the optical path of the reflected imaging beam is coincident with the optical axis of the projection lens group. In another particular embodiment, the display device is tilted with respect to the optical axis of the projection lens group to accommodate the tilt in focal plane of the projection lens group caused by the redirection of the imaging beam.

摘要： A method is disclosed for addressing a matrix-array type liquid crystal layer. The cell has a plurality of pixels which are defined by regions of overlap between two sets of electrodes which sandwich a liquid crystal layer, each pixel having two states. The response time for switching between the two states is dependent upon the voltage across the liquid crystal layer, with a minimum occurring at a particular voltage. The method includes applying a strobe waveform to a selected member of a first set of the electrodes while a data waveform is applied to each member of the second set of electrodes. A waveform for switching a pixel defined by the selected member comprises a switching pulse of a given voltage magnitude and given duration. A waveform for not switching a pixel defined by the selected member comprises a non-switching pulse of a voltage magnitude greater than the given voltage magnitude of the switching pulse and a duration less than the given duration of the switching pulse.

摘要： ##STR1## Ferroelectric smectic liquid crystal mixtures are provided consisting of two constituents; a smectic host and another containing a chiral compound in which rotation of the chiral center relative to the molecular core is sterically hindered, so that the chiral compound induces a high Ps in the mixture. A preferred class of chiral compounds is those derived from naturally occurring compounds with chiral groups, especially α-hydroxycarboxylic acids, amino acids and terpenoids, e.g. with chiral groups (I), (II), (III). The chiral group is incorporated into a compound containing a mesogenic combination of groups, e.g. with chains of cyclic groups and some mesogenic combinations are described.

摘要： The mechanism of and a solution to the problem of vertical banding in projection systems is disclosed. An offset lens array includes a plurality of lens elements arranged in a plurality of rows that are offset with respect to one another. The offset lens array is incorporated in an illuminator for a projection system. The asymmetrical arrangement of the rows of lens elements in the array with respect to a seam in a color separation element of the projection system substantially reduces the vertical banding in the projected image.

摘要： An off-axis projection system includes a polarizer, a reflective light modulator, an analyzer, and an aberration compensation element. The polarizer polarizes an illumination beam to form a polarized illumination beam. The reflective light modulator receives the polarized illumination beam along a first optical path, modulates the polarized illumination beam to form an imaging beam, and reflects the imaging beam along a second optical path not parallel to the first optical path. The aberration compensation element is disposed in either or both of the polarized illumination beam and the imaging beam. The separation of the illumination beam and the imaging beam provided by the off-axis architecture facilitates the use single-pass aberration compensation elements, including liquid crystal compensation films and wave retarders. A multi-color projection system is also disclosed.

摘要： A projection system includes a collimating lens group for collimating an imaging beam. The collimating lens group has an optical axis that is de-centered with respect to the axis of the imaging beam. Further, the optical axis of the collimating lens group forms a non-zero angle with the axis of the imaging beam. The de-centered collimating lens group enables the use of more conventional projection optics, without the unacceptable displacement of the projected image.
