Sony has announced a new LCD display technology called Hybrid FPA
(field-induced photo-reactive alignment), which it claims provides a
bevy of improvements for LCDs in the areas of response time, contrast,
panel stability, and production speed. For those of you who slept
through display science in school (no shame), this boils down to Sony
finding a better way to wrangle unruly liquid crystal molecules (LCMs)
into more optimal alignments -- which is important since this affects
how light passes and therefore how images are resolved. The new
technique builds on earlier work, which focused on the vertical
alignment of LCMs via an alignment layer. As the left diagram shows,
through pre-tilt positioning at the substrate layer, LCMs were forced
into a more stable vertical state, which made shifting them quicker
and more precise while requiring less voltage. In other words, images
resolved faster and more evenly, resulting in "cleaner" whites and
blacks with less motion blur. Hybrid FPA simply improves the situation
by aligning LCMs even more vertically, which produced response times
of less than 3ms in tests. That's great news for 3D lovers and gamers,
and should help Sony at least move units off of retailer shelves at
some point, particularly if its plans for rapid commercialization of
this tech hold true.
