Apple, Samsung Win Praise for Display Technologies

Apple and Samsung this week won awards for display technologies on their mobile devices.

Apple’s iPhone and iPad earned gold Display of the Year and Display Application of the Year awards from the Society for Information Display. Both devices received praise for their usage of in-plane switching technology, in which crystal molecules are oriented so their motion is parallel to the panel, instead of perpendicular to it. The result is a very wide viewing angle — up to 180 degrees — with brilliant color.

Apple’s iPhone 4 high pixel-density “Retina Display” is reportedly manufactured by LG Displays, which is also the main supplier for the iPad’s display.

Meanwhile, Samsung earned silver awards for displays on its Galaxy S smartphones, as well as its on-cell touch active-matrix organic light-emitting diode (AMOLED) display technology. Samsung’s displays gained applause for using Super AMOLED technology, in which pixels emit their own light so the display does not require backlighting, to “deliver very high performance and exceptional display quality,” according to the society.

Also, Samsung’s on-cell touch technology integrates the touch sensor into the display itself, rather than putting the sensor on a separate piece of glass and laminating it on the display, which allows the display to be thinner and more responsive, the society said.

“[The award winners] demonstrate the remarkable contributions made by the display industry to broaden and enhance the lives of people,” said Bob Melcher, chairman of the SID Display of the Year Awards committee, in a press statement.

Display technologies take on an increasingly important role in the gadget industry as the newest mobile devices continue to shed physical keyboards and buttons in favor of touchscreens. Today, a smartphone’s display is as important as the software that runs beneath it.

Many display experts agree that Apple’s gadgets lead the game in the display industry thanks to their usage of in-plane switching, but Samsung’s AMOLED displays are not far from catching up.

“While OLED is still a relatively young display technology that has not yet been perfected to the performance levels of the very best mature LCDs [such as those on the iPhone and iPad], the Galaxy S is already an impressive display for an upcoming and rapidly evolving technology,” said Raymond Soneira, a display expert at DisplayMate, who has done independent testing on various displays.

HP x2301 Micro Thin monitor makes other displays feel bloated, insecure

HP x2301 Micro Thin

Those new desktops HP unveiled today are little more than humming foot rests without a monitor, so the company also trotted out the x2301 Micro Thin — a 23-inch, LED-backlit, 1080p display that’s an absolutely anorexic 9.8mm (0.39 inches) thick. Most of the important internals have been shoved into the blue-tinted base to keep the brushed aluminum and glossy black screen as thin as possible. It’s not exactly a high-end model, but the 3ms response time and 8,000,000:1 dynamic contrast ratio are nothing to sniff at. The x2301 is expected to ship on June 10th for $280, just after its slightly cheaper (and chubbier) cousin, the Elite L2201x. Fashionistas, the line starts right around the bend.

Toshiba enters pixel density fray with 367ppi LCDs for cellphones

Toshiba LCDToshiba just fired its own salvo in the pixel density wars at SID 2011. The company is showing off a range of LCDs for cellphones that top out at an almost imperceptibly fine 367ppi on its 4-inch HD (720 x 1280) model. Beyond just cramming more red, green, and blue dots in each inch, these panels also top the bar-setting Retina Display in the contrast department with an impressive 1,500:1 ratio. The company also brought a smaller 3.3-inch screen with a resolution of 480 x 864 to Display Week that hits a respectable 300ppi. They’re not quite as impressive as these HAST LCDs, but who really needs to put 1080p in their pocket? (Want is a different story.) Of course, Engadget is on the scene and, if you’re lucky, we’ll let you live vicariously through us as we tour Toshiba’s booth — you know, as a reward for your loyal readership.

Samsung Demoes Retina-Resolution Tablet Display

PenTile displays use less subpixels but produce output that is tailor-made for our brains

Samsung has a new 10.1-inch “retina” resolution LCD panel ready to show off next week. It will demonstrate the 2560 x 1600 panel at the SID Display Week 2011 International Symposium starting Tuesday May 17th. And if you weren’t already thinking it — yes, this is perfect for tablets.

The panel has a resolution of 300dpi, the same as that of print, and the number Apple uses to define its Retina displays. In most uses, the pixels disappear and it appears that you are looking at a printed page.

Samsung’s new panel is interesting for two reasons. First is that it uses PenTile RGBW tech. PenTile is a way of grouping subpixels — each multicolor “pixel” on a screen is made up of several smaller single-color dots. In the case of PenTile, there are five dots (hence the “pent” or “penta” part of the name). The RGBW part means that an extra white pixel is added to the usual red, green and blue ones.

This white pixel works in conjunction with a variable, locally dimming backlight. This ramps up when bright colors are needed, but when colors are desaturated or just black and white, the backlight dims and only the white pixel is switched on. This reduces power consumption by a claimed 40% vs. a regular RGB stripe panel.

And that power reduction is the key to its use in tablets. The biggest draw on tablet battery power is the screen. Until a panel exists that can deliver the same battery life as today’s tablets, we won’t see a Retina display in the iPad. Of course, driving all of those extra pixels is also extra work (4x) for the graphics chips, but that’s another problem.

Samsung Central Station hands-on (video)

The last time we saw Samsung’s Central Station in person it wasn’t so much of a hands-on moment as a drive-by peep show. Nearly four months later, it’s about to go on sale, and Samsung finally let us play with a final unit. For those of you who missed it in Vegas, the Central Station is a 1080p monitor that doubles as a docking station, replete with HDMI and VGA output, a speaker port, four USB ports (two of ’em USB 3.0), plus an additional USB port just for wired connections (more on that in a bit). The best part, of course, is that all of this docking happens wirelessly with the help of a small dongle that plugs into your laptop’s USB port — even if it’s of the 2.0 variety. The promise is that all you need to do is walk within range of the monitor to be able to mirror (or extend) your desktop, stream 1080p video, and access USB peripherals, such as external hard drives. So is this display as simple to use as advertised? Mosey on past the break and check out our hands-on video to see for yourself.

Acer’s Web Surf Station looks like a monitor, acts like an all-in-one

We’d say we’re pretty well-covered when it comes to devices that turn on instantly to let you surf the web, scan your Facebook feed, and browse photos. But if you crave that immediacy and a larger, more comfortable viewing space, Acer’s DX241H Web Station might be the product you’re looking for. Available in wired and wireless models, this 24-inch monitor has a built-in browser, and can get online without being connected to a PC. While web surfing is clearly the marquee feature, you can also watch movies on its 1080p display by using Acer’s clear.fi software to stream video and other media from other devices on the network. Spec-wise, it also boasts DLNA compatibility, VGA and HDMI output, USB ports, and a memory card slot. People in the UK too impatient to wait for an all-in-one to boot up can snag the Web Station for £299 ($495) in May.

An Apple HDTV Might Be Ready for the World, But Is the World Ready for an Apple HDTV? [Rant]

An actual Apple television. More than a few people believe it’s on the way. And more than just offering hardware without good content deals in place (BOXEE, GOOGLE…I’M LOOKING AT YOU), it’s rumored that such a device would either run iOS apps, play host to a revamped iTunes video subscription service, or both.

Dual Display Kyocera Echo Available For Pre-Order From RadioShack

kyoceraecho.pngApril Fool’s Day: The perfect time to pre-order a phone that already looks just a little bit crazy. The dual-screen Kyocera Echo, soon to come to Sprint, is now available for pre-order on RadioShack’s website and in stores. Running Android 2.2 (Froyo), the Echo can use one screen as a keyboard or run two apps at once with one on each screen. It can also combine the two into one 4.7 inch super-screen. Other than the fact that it has two independent displays, the rest of the phone’s features are pretty standard, with a 5 megapixel camera, 720p camcorder and wifi hotspot mode.

RadioShack is selling the phone, which costs $199 on contract, on its site with free shipping. You can also pre-order in RadioShack stores, but that will require the purchase of a $50 gift card, applied to the purchase of the phone when it comes out on April 17th.

Samsung Starts Building 22-inch Translucent LCD Displays

Samsung - Translucent LCD

Remember that video about how everything in the future would be covered with interactive glass? Samsung doesn’t seem to think it’s too off base: they’ve begun mass production of 22-inch translucent AMOLED LCD displays in both monochrome and color models. The new displays aren’t completely clear, but they’re translucent enough for a viewer to be able to make out objects and people on the other side of the display while there’s an image on the screen. 
Samsung sees the technology as useful for shop windows, billboards, or show floors and showcases where companies want a way to demonstrate their product without obscuring the view past it, or that just want to show off. 
The displays aren’t too bad by traditional LCD standards either: they offer 500:1 contrast ratios and run at a native resolution of 1680-pixels x 1050-pixels. Add this to the fact that it doesn’t use a backlight and you have an energy efficient, very futuristic LCD panel. 
There’s no word on exactly how much the translucent LCDs will cost, or who will really buy them: it will almost definitely be a while before they make their way into homes and businesses. Still, it’s clear that they’re coming, at least for some applications. Check out a video of the new panels in action behind the jump.

Samsung mass-producing 22-inch transparent LCD, your desktop monitor seethes with jealousy

They said they would do it, and by golly it’s nearly here — Samsung just revealed that its assembly lines are starting to churn out see-thru computer screens that don’t require power-sucking backlights to function. Unfortunately, it looks like the amazing AMOLED variety is still on the drawing board, but ambient light-powered LCDs are on the way, with Samsung offering a 22-inch, 1680 x 1050 resolution panel with a 500:1 contrast ratio to begin with. Sammy suggests we’ll see it in HDMI and USB-compatible monitors and suspects it’ll be used in advertising and teleconferencing first — which suggests this display won’t come cheap — but we all know the true killer app will be a nice big frameless laptop screen. We’ll take two, please. PR after the break.
