Rare earth (RE) ions activated inorganic phosphors with multi-color emissions have received considerable attention because of their emerging applications in solid-state lighting, backlight displays, lasers, biomedical imaging, and so on. This tutorial review concerns the design principles for Eu2+ Eu3+ red-emitting solids highlights influencing factors on luminescence performance. Based recent ...

An autostereoscopic display system, which allowed multiple viewers simultaneously by use of head-tracking, was previously demonstrated for TV applications in the ATTEST project. However, the requirement for a dynamically addressable, movable backlight presented several problems for the illumination source. In this paper, the authors demonstrate how the use of a novel laser-based holographic pro...

We proposed a scheme to drive the light emitting diode (LED) backlight and liquid crystal (LC) panel simultaneously to achieve 10,000-nit 12-bit perceptual quantizer (PQ) curve, which is required by high dynamic range (HDR) displays. Besides the relative fast response time and low driving voltage, this approach can also mitigate image noises.

In this paper, we present algorithms for the calculation of local dimming LED-Backlight. They assure clipper-free results and can be implemented at low HWcosts. The power saving is in average 38.7% compared to global dimming. For a XGA display 72K (RGB) logic gates are needed to implement this algorithm on chip.

This integrated single inductor dual-output boost DC/DC converter provides two independently regulated outputs with maximum efficiency at 83%. The converter operates in PWM and discontinuous mode at 500kHz using a 6.8uH inductor. Each output is time-multiplexed and regulated via current mode control. A drain-extended 0.13um technology allows backlight application up to 11V operation. The chip o...

We realize homogenous luminance of the directional backlight for the time-division multiplexing autostereoscopic display using a convex lens array with the elemental lenses whose phase of placement in each row differs from one another. The validity of the proposed optical design is confirmed by a prototype system. key words: autostereoscopic display, homogeneous brightness, liner Fresnel lens a...
