The Sony NGP/PSP2: What we still don't know

Last night's Tokyo announcement of the PSP2, now known as the Sony Next Generation Portable, revealed details that had been previously mentioned in a variety of rumors. To a large extent, those rumors proved correct: no UMD drive, but a 5-inch high-resolution OLED screen, 3G capabilities, front and rear touch capabilities, and--yes--dual analog sticks are all part of the NGP's design.

However, much as with the first announcement of the Nintendo 3DS, a lot of key details are still undefined.

Rounding up the PSP2 rumors so far

It looks like it's turning into the year of the next-gen gaming handhelds, now that Sony's rumored PSP2 is expected to be announced on Thursday, right on the heels of the Nintendo 3DS event last week. Though it's not a surprise that sooner or later a new PSP would emerge, the real question is whether it can recapture any of its lost market share.

It's an interesting time for the venerable and somewhat struggling handheld game market. Smartphones and low-priced apps have become a more popular gaming platform for many. What makes a PSP2 any better … Read more

LG unveils 'world's thinnest' 3D OLED TV

OLED TVs are nothing new since Sony launched its XEL-1 back in 2007. Still, the LG prototype that will be on display in the upcoming IFA trade show in Berlin is a different beauty altogether. First of all, this Korean entry is a sizeable 31-incher claiming the title of "world's thinnest" OLED TV, measuring just about one-tenth of an inch. Secondly, this sleek panel supports 3D playback just like the LG LEX8, LEX9, and PX950N 3D TVs that will also be on showcase at the September 3 trade fair.

The only problem is that this is one … Read more

Behind the scenes at GE Global Research

NISKAYUNA, N.Y.--When you're listening to someone explain a new scientific method and just about the only thing that goes through your head is "This is going to win a Nobel Prize," you know you're in good company.

That was my experience recently while I was listening to Fiona Ginty, a project leader in computational biology in General Electric Global Research's biosciences group, explain her work. Ginty's project is all about finding new and better ways to spot cancer in a patient's body, ideally as early as possible. And as a member … Read more

'Optimus Popularis': Minimalist OLED QWERTY

Art Lebedev Studios made waves a few years ago when it introduced the Optimus Maximus. The QWERTY keyboard had individual OLED screens under most buttons, meaning it was almost infinitely customizable. It was thought to be nothing more than vaporware by some until it actually shipped. It remains a sought-after luxury keyboard.

And now, via its Live Journal (!?) the same studio has previewed a new slim, minimalist keyboard that also includes LCD keys, called the Optimus Popularis. It's slimmer and smaller than the Maximus, and the design's more modern. It shares more with laptop keyboards than with most … Read more

LED TVs: 10 things you need to know

Editors' note: Updated June 3, 2010

I've written articles in the past explaining various TV technologies, including the differences between 720p and 1080p and 120Hz and 240Hz LCD TVs. But with Samsung, LG, Sony, and other manufacturers pushing so-called LED TVs these days, it's high time that I--with an assist from our resident video guru, David Katzmaier--sort through all the marketing mumbo jumbo and provide some insight into just what an LED TV is. Here goes.

1. An LED TV is not a new kind of TV.

I appreciate a good marketing ploy as much as the next guy, but an LED TV is just an LCD TV that's backlit with light-emitting diodes (LEDs) instead of standard cold-cathode fluorescent lights (or CCFLs). And though they became well-known last year with Samsung's ultrathin models, LED-backlit LCDs have been on mainstream store shelves since 2007, when Samsung's LN-T4681F debuted.

Unlike plasma and OLED, which are emissive technologies where each pixel is its own discrete light source, LCD is a transmissive technology where each pixel has to be illuminated from behind, or backlit.

2.There are two LED backlight configurations

Initially, LED-based displays like the Samung LN-T4681F were backlit by what's referred to as a "full array" of LEDs behind the LCD, across the back of the panel--just like a standard CCFL backlight. But to create even thinner TVs, engineers needed to eliminate that extra layer of LEDs and move it to the sides of the display. With this form of backlighting, the LEDs are affixed to all four sides of the TV and light is projected inward to the middle of the TV via "lightguides." These types of TVs are commonly referred to as "edge-lit" LED-based LCDs, and are by far the most common available today.

3. Each configuration may also offer "local dimming."

All current LED-based LCDs with rear-placed, full-array LED backlighting--except the Sharp LC-LE700UN series from 2009--feature a technology called "local dimming." With local dimming, portions of the backlight can be dimmed or brightened independently when different areas of the picture get darker or brighter. For example, the LEDs behind the words in a credit sequence can illuminate while the ones behind the black background remain dim.

Being able to dim portions of the screen helps reduce the amount of light that leaks through to darkened pixels, and the end result is blacks that appear darker and more realistic. Since black levels are crucial to contrast ratio, the deeper the blacks, the more the picture--and colors--appear to pop. Also, the image as a whole will seem crisper. A couple of examples of local dimming done right are Samsung's UNB8500 series and LG's LH8500 series--respectively the best and second-best LCDs we've ever tested.

One downside to local dimming is an effect called "blooming," where brighter areas bleed into darker ones and lighten adjacent black levels.… Read more

Crave 03: Moonbots, Velcro, and hoverboards (podcast)

This week, Donald's back in the studio, joined by Eric Franklin and Dong Ngo from Inside CNET Labs. We ponder Japan's plans to turn the moon into a playground for robots, and tackle OLED displays that roll and vanish. Dong drops some knowledge on recent hard drive innovations and a waterproof case for his Flip Ultra HD. The iPad meets Velcro. And the hoverboard makes a comeback (kinda).

Sony unveils ultrathin rollable OLED

Sony on Wednesday unveiled a flexible OLED (organic light-emitting diode) display so thin it can wrap around a 4mm cylinder--roughly the diameter of the average pen or pencil.

The 80 micrometers-thick OLED display (about the width of a human hair) can continuously display moving images even while being rolled up, as Sony demonstrated in a video below.

The working flexibility is possible because engineers have managed to lose the rigid driver IC chips usually used in the substrate of a screen in exchange for a gate-driver circuit with OTFTs (organic thin-film transistors), according to Sony.

The 4.1-inch display, which … Read more
