2.1 NEW TECHNOLOGY
2.1.1 New optical engine with wire-grid polarizers
Using a conventional PBS (Polarizing Beam Splitter), comprised of a glass prism on which has been deposited a multilayer interfer-
ence film, optical properties can vary considerably depending on the angle of the incident light beam; this makes it difficult to realise
high contrast.However, the wire grid design employed for JVC's newly developed optical engine uses an inorganic reflective polarizing
plate made from a glass substrate on the surface of which are aluminium ribs with a width of a 20~30 nanometers, aligned with a pitch
of 120~130 nanometers. This has very little angle-dependence and it succeeds in reducing to an absolute minimum the amount of
stray light reaching the lens during dark scenes. The combination of this polarizer with the newly developed D-ILA device increases
contrast by a factor of 5
2.1.2 Image processing circuit with video processor made by Gennum Corporation
images thanks to a high-precision scaling function and four VXP
™ technologies as the followings.
VXP
™ Technologies
FineEdge
™
Edge correction technology that gets rid of the jaggy artifacts
that can affect diagonal lines, creating instead smooth out-
lines.
FidelityEngine
™
Imaging technology that improves detail while reducing noise.
This technology ensures a clear, detailed picture even when
using video sources with lower resolutions.
TruMotionHD™
De-interlacing technology that supports HD signals (1080i),
converting them to high-quality 1080p signals for playback.
RealityExpansion
™
10-bit image processing technology. This technology can up-
sample 4:2:2 (Y:Cb:Cr) video signals to the 4:4:4 format; it de-
livers outstanding image processing at a level comparable to
that of broadcast masters.
