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 Samsung shows off 55-inch glasses-free 3D TV prototype

Samsung hasn’t exactly been as big on glasses-free 3D TVs as some other manufacturers in recent years, but it’s now showing one off at the FPD China trade show — or a prototype of one, anyway. According to Tech-On!, the 55-inch display is able to accomodate nine different viewpoints for glass-free 3D viewing, and it can be switched into a 2D mode at any time, which works by changing the optical refraction index of an LCD panel that sits on top of the main LCD that’s actually used to display images. Right now, the prototype is also relying on a direct-lit CCFL backlight, although Samsung notes that would likely be replaced with an LED backlight before it actually hits the market — something that’s still a good three years away.

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 Is your iPad 2 backlight bleeding? (video)

Now that many of you have collected and used your second generation iPad tablets for a few hours, we’re starting to see the inevitable reports of defects. Thus far, two issues have bubbled to the surface. The first issue — yellow spots beneath the LCD glass — is reminiscent of the same fresh-from-the-factory iPhone 4 issue that resolved itself just as soon as the bonding agent used for the LCD glass had time to evaporate. The second issue, which is being conflated with the first, is characterized by light bleeding through from the outer edges of the LCD panel. The bleeding is most noticeable when watching a dark scene in a movie or using an app with a black background as demonstrated in the picture above and video embedded after the break. For those affected, the issue can be minimized or exacerbated by adjusting the brightness in settings. So what say you dear reader, are you also a bleeder?
