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.
It may not have the charm or good looks of, say, the uBOT-5, but a new wearable vital signs monitor could cut back on doctor’s visits for the chronically ill. Produced by a Kansas State University student, the GumPack — known as such for its size — is a multi-sensor monitoring device that fits in the palm of your hand and relays vital stats to your doctor via the internet. Along with a built-in camera and microphone for record keeping, as well as WiFi capabilities for connectivity, the battery-powered GumPack will sport various sensors, like a reflectance pulse oximeter or a two-thumb ECG. The monitor is still in the concept stage, and will likely not be available for mass-market distribution for years — if ever — but with technology like this in the works, the “I’ve fallen and I can’t get up” lady might as well start looking for a new gig.
Wirelessly-powered TVs are nice, and transparent displays are cool and all, but what about an ambient light-powered transparent LCD? Well, that’s nothing short of awesome. Samsung showed off just such a device at CeBIT 2011 last week — a prototype 46-inch display with 1920 x 1080 resolution and ten-finger touchscreen capability. We aren’t sure what kind of black magic Sammy put in this thing, but it’s an incredible feat of engineering to make such a large display — and its accompanying solar cells — efficient enough to run exclusively off the juice it pulls from surrounding light sources. No word on how the photon-powered LCD compares to existing HD monitors in terms of brightness, refresh rates, or color reproduction, but a muted picture is a small price to pay for cutting the electrical cord forever.
We’ve been keenly tracking the progress of these 3D displays from Samsung, from their pre-CES tease — where we were first told they were TVs, then monitors, then it turned out they were monitors with optional TV tuners — through their official launch and now to their first pricing and availability. South Korea is the unsurprising debut market for the 950 and 750 Series, both 27-inchers, discernible by their design, which in the 950’s case is asymmetric and in the 750’s is all about the thin bezel. A 1,000:1 contrast ratio, 2ms response time, 1080p resolution, and a litany of input ports await the buyer of either one, but he’d better bring a well-fed wallet to this party — the 27TA950 reportedly costs 890,000 KRW (nearly $800) whereas the 27TA750 is an 840,000 KRW outlay (just over $750). Not exactly value models, but those prices will likely change when the pair go international at some point later this month.
Calibrating your monitor in order to maximize color accuracy is considered an inevitable chore for graphics professionals, but here comes Eizo with a defiant look on its face and a brand new 27-inch IPS display. The ColorEdge CG275W promises to do all the adjustments itself, eschewing the need for a separate calibration utility, and can even be set to do it overnight, freeing your creative mind to collect its much needed ration of Zs. Brightness maxes out at 270 nits, contrast is rated at 850:1, and there’s a 6ms gray-to-gray response time, not bad for the traditionally slower IPS tech. DVI, DisplayPort and Mini DisplayPort connectivity is augmented with a USB 2.0 hub, while the stand can tilt, rotate and swivel in typical Eizo fashion. You also get that fetching hood that’s compatible with both portrait and landscape orientation. Shipping begins at the end of this month, with pricing varying by territory.
