Transflective liquid crystal display with partial switching

InactiveUS7015997B2Improve reflectivityIncrease reflectionNanoopticsNon-linear opticsLiquid-crystal displayBirefringence

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.

Method and system for 80 and 160 gigabit-per-second QRZ transmission in 100 GHz optical bandwidth with enhanced receiver performance

InactiveUS20060228118A1High receptionHigh transmissionPolarisation multiplex systemsWavelength-division multiplex systemsFiberFir system

Optical transmitter / receivers for use in a DWDM systems are provided. Transmission of data signals in a quadrature-return-to-zero (QRZ) format achieves a data transmission rate equal to eight times a base data rate, i.e., 80 Gbps over a 100 GHz channel if the base data rate is 10 Gbps, with high non-linear performance by setting the polarization state of the data bands such that non-linear effects induced by PMD are reduced. Additionally, a transmitter achieves a transmission data rate equal to 16 times the base data rate by sharpening the QRZ pulses and interleaving pulse-sharpened QRZ data signals in the time domain, further doubling the data rate. Using counterpropagation in the transmitter, carrier signals and data signals traverse the same length of fiber, reducing fringing effects in the transmitter. Related techniques enhance reception and detection of data at high data rates. A local pulse-sharpened carrier is mixed with a QRZ data signal at a detector reducing amplification noise by a factor of two. A bi-directional Erbium-doped fiber amplifier is used to amplify a carrier signal while limiting fringing effects by sending carrier and data signals along equal optical path lengths. Non-linear effects are reduced by transmitting carrier signals in an othogonal polarization state with respect to data signals, and PMD phase noise effects are compensated for in both single channel and DWDM multi-channel systems by using delay management.

A hollow sphere with a scattering (e.g., white diffusive) interior surface directs light input from at least one input light source to an exit. In one embodiment, an internal hot mirror and phosphor are positioned to intercept the input light on which visible light is reflected and ultraviolet light is directed to the phosphor for conversion to visible light. The exit has a reflective polarizer that passes light of a selected polarization to an output. Light of other polarization(s) is reflected back into the sphere where it becomes unpolarized because of reflections and may eventually be returned to the exit at the selected polarization.

Embodiments described herein provide a method for cross-channel scheduling of high efficiency (HE) multi-user (MU) frame transmission. In some embodiments, channel information and client station information may be obtained for data transmission. An MU frame containing a data field of a first type and two data fields of a second type may be configured to carry scheduling information relating to one or more channels for the data transmission. It may be determined that a current scheduling setting of the two data fields of the second type leads to unbalanced payload between the one or more channels. The two data fields of the second type may then be adjusted for a balanced channel mapping, and the data field of the first type may be adjusted to reflect the balanced channel mapping. Data based on the adjusted data field of the first type and the adjusted two data fields of the second type may be transmitted via the one or more channels.

A waveguide image combiner is used to transmit a monochrome or full-color image in an augmented reality display. The combiner uses multiple stacked substrates and multiple pairs of incoupling and outcouping VHOEs to expand a first FOV and an image expander to expand the second or perpendicular FOV. This suitably provides an expanded FOV that offers a diagonal FOV≥50°, a horizontal FOV≥40 and a vertical FOV≥25°. The combiner also delivers a large horizontal eye box up to 20 mm and a vertical eye box of 10 mm while maintaining high light efficiency of the real scene (e.g. >80%). The system is able to use a light engine based on broadband (10 nm≤Δλ≤40 nm) LEDs and maintain a large horizontal field of view and high transmission of the real imagery. The approach resolves issues with current embodiments including astigmatism, image overlap, color balance, and small light engine pupils leading to reduced eye boxes.
