postheadericon Toshiba and Hitachi LCD plants damaged, will shut down for a month

You can’t have a 9.0 magnitude earthquake without breaking a few factories, particularly ones that produce fragile liquid crystal screens, and this week Toshiba, Hitachi and Panasonic are each reporting damages that have forced them to close LCD production facilities affected by the tsunami and quake. Panasonic isn’t sure when its plant in Chiba prefecture might resume carving up the glass sandwiches, telling Bloomberg that “there has been some damage, though not a fire or a collapse,” but both Hitachi and Toshiba will reportedly halt some assembly lines for around a month to deal with damages. It’s probably still too soon to talk about panel shortages — though they seem likely soon — but we’ll let you know how things progress.

postheadericon LCD technology torn down and explained in the most lucid and accessible terms yet (video)

Look, we know you know all about LED backlights, light diffusion, subpixels, and the things that turn them on, but not everybody does. The humble LCD you’re most likely reading this on still retains a level of mystery about the nitty gritty details of how it works for the vast majority of its users, so here’s a terrific video breakdown of both its component parts and method of operation. Bill Hammack, a self-appointed Engineer Guy, takes us from the LED arrays that provide the light for most current LCDs, through all the filters and diffusers designed to make that light uniform, and into the ways thin film transistors make it possible for us to show moving color images of cats diving into boxes on such displays. It’s exciting, deeply nerdy stuff, and it awaits your audience after the break.

postheadericon Sony ‘Hybrid FPA’ liquid crystal alignment technique sets LCD issues straight

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.

CPT's Colorful Sunlight Readable screen uses half the power of an LCD (video)

The last time we heard from CPT it was showing off what looked to be a competitor to Pixel Qi, a super low-power transflective display. Now the company is demonstrating something completely different, new enough to not really have a name but promising to deliver all the quality of a standard LCD at less than half the consumption of a typical backlit display while also working well in direct sunlight. Sadly that’s about all that’s known about it at this point, but you can see a prototype working in the flesh after the break. Well, a video of one in the flesh, anyway.
