Fact: Blue images always look sharper than white images to the user. Siemens Display Technologies implemented blue backlights in its flat panel display product line and had the same feedback from its customers: bluish pictures look brighter. Therefore we wanted to research this theme and try to explain this unique “feature” from a more theoretical point of view. We can explain why, under interi...

168 LLE Review, Volume 72 The cold, compressed shell in laser-driven implosions can normally be imaged only by backlighting because its x-ray emission is very weak. However, a high-Z–doped shell can be imaged using the Kα line radiation, which fluoresces due to excitation by the intense radiation from the hot core. We show results from titanium-doped target implosions where the onedimensional s...

We report a new turning film structure for widening the viewing angle of a vertical-field-switching blue-phase liquid crystal display, which employs a directional backlight. The turning film consists of periodic prismatic structures: each period has three prisms with different base angles so that the output light can be spread to a larger angle. Simulation results show that a full width at half...

This paper addresses the influences of standard operating parameters like backlight, contrast, sharpness, etc. of an autostereoscopic display on subjective quality, in the absence of transmission quality impairments (best case reference). Therefore, a useful test environment is specified and applied. Results show that the influences of different display setups are distinguishable from each othe...

Light-guide plates (LGPs) with aperiodic or size-varied microstructures are widely used in edge-lit light-source backlight systems for their high uniformity. In this Letter we designed a LGP with periodic and single-sized microstructures and analyzed the relationship between the holistic arrangement density of the microstructures and the uniformity. By controlling the holistic arrangement densi...
