We present experiments on 3D visualization of partially occluded objects using axially distributed sensing. The axially distributed sensing method provides collection of 3D information for a partially occluded object and the 3D images are visualized using the modified digital reconstruction algorithm based on inverse ray projection model. We apply this method to a camouflage setting where the obje... View full abstract»

A simplified single-cell-gap transflective liquid crystal display with two thin-film-transistors and only one data line is proposed. The simulated voltage-dependent transmittance (VT) and reflectance (VR) curves overlap reasonably well, which enables a single gamma curve driving. The need of only one data line improves the aperture ratio, reduces the fabrication cost, and stabilizes ... View full abstract»

The stamping process of self-assembled monolayers (SAMs) with polydimethylsiloxane (PDMS) mold on the Ag electrode was demonstrated, for use as the anode of a top-emission organic light-emitting device (OLED) and the cathode of an organic photovoltaic (OPV) device stacked underneath. Such SAMs reduce the barrier for hole injection from the Ag to the hole-transport layer of OLED. The PDMS mold coat... View full abstract»

A 640-channel 6-bit LCD column driver with a cross-self-bias push-pull buffer is presented. To design a column driver for thin-film transistor liquid-crystal displays (TFT-LCDs), both low power consumption and chip area are key problems that must be solved. Therefore, the proposed cross-self-bias buffer amplifier effectively reduces the circuit area and power consumption overheads of conventional ... View full abstract»

Compared to the OLED with planar substrate, the luminous current efficiency and luminous power efficiency of the device are shown 25% and 36% enhancement, respectively, by attaching the microlens array film (MAF) having a fill factor of 0.788 and a height ratio of 0.46. Both the luminous current efficiency and luminous power efficiency of the organic light-emitting device (OLED) increased monotoni... View full abstract»

A fast response time, wide viewing angle, and single-cell-gap transflective display using polymer-stabilized blue-phase liquid crystal is proposed. The transmissive region has an in-plane wall-shaped electrode while the reflective region has an in-plane trapezoid electrode. Both of the electrodes generate a strong horizontal field, resulting in a low operating voltage and high transmittance and re... View full abstract»

When integral imaging systems work in their conventional configuration, the reconstructed images are pseudoscopic. The two-step pickup process is capable of giving an orthoscopic image, but it involves black zones, which affect the viewing angle. We analyze the black zones on the elemental images. The improved two-step pickup process is proposed to solve this problem, and the mathematical models o... View full abstract»

Theoretical and experimental investigations of moirés in three-dimensional displays are performed in the spectral domain . The method of investigation of spectra basing on summation is proposed. It gives the trajectories of spectral lines. The equations of trajectories are found analytically and confirmed experimentally. The locus of the optimal angle on the trajectories is found. The phen... View full abstract»

Inter-electrode coupling phenomena and their influences on crosstalk defects are theoretically studied in thin-film-transistor liquid crystal displays (TFT-LCDs). The proposed mechanism for crosstalk defects is confirmed through experimental performance. The theory and the experimental results show that inter-electrode coupling is significant in recent low-cost TFT-LCD panels, resulting in strong ... View full abstract»

For thin-film transistor liquid crystal display (TFT-LCD) panel manufacturing, a gate driver circuit with amorphous silicon TFT plays an important role. In this paper, an amorphous silicon gate (ASG) driver circuit is optimized to improve circuit's dynamic characteristics. The adopted simulation-based evolutionary method integrates genetic algorithm and circuit simulator on the unified optimizatio... View full abstract»

The optical geometry of two adjacent detectors in the focal plane of a scanning millimeter wave imaging system is similar to that of a stereo camera with optical axes of two component cameras which are diverging radially. The perceived image characteristics of the diverging-type stereo camera are analyzed, and they are compared with those of other camera arrangements, such as parallel- and radiall...

In the application of projection display, the effective flux utilization is an important factor to the optical system with more optical efficiency of the system with utilization of the light source such as LEDs. In this paper, based on Monte Carlo ray tracing we simulate light extraction efficiency as well as directionality of the light pattern of sapphire-based and Thin-GaN LEDs implanted with mi...

Optical fibers are described that emit visible light along their length when particulate up-converters in the cladding are excited by light from semiconductor light sources propagating in the core and leaking into the cladding. These eye-catching fibers can be made in almost any color. They can enhance the display of safety gear, enliven novelty clothing displays, make more spectacular theatrical ... View full abstract»
