Samsung demos USB-powered display

Tech-On's pictures show Samsung's prototype monitor running entirely from USB power.

Samsung has previewed a neat new product at the SID 2010 conference: an 18.5" LCD monitor capable of running entirely from USB - no mains adapter required.

According to coverage over on Tech-On, the new monitor is an extremely energy efficient display based around a TN LCD panel featuring a transmittance of around 7 percent - a significant improvement over existing displays. Coupled with the use of edge-lighting via LEDs, Samsung has been able to drop the peak power consumption down to just 6.3W.

Such low power consumption means that the device can be run entirely from bus power over USB - admittedly using a twin USB cable which splits the power draw over a pair of ports.

While host-powered displays are nothing new, Samsung's latest is the largest so far - and likely to prove popular amongst laptop users who want some extra screen real estate while out and about, although strangely Samsung appears to be aiming its initial design run at the desktop market - a group which could quite easily use a traditional monitor which plugs into the mains.

While an actual product based around the technology isn't due until 2011, Samsung has offered up the specifications of its prototype unit: a 1,366 x 768 widescreen resolution, 250cd/m2 brightness, and a contrast ratio of 1000:1. Sadly, there's no clue as to response time - meaning that this is likely to be a gadget for the professionals rather than the gamers.

Do you think an ultra power-efficient USB-powered display is just what you're after, or are you struggling to see the point if there's a power socket nearby? Will it all depend on the specifications - and pricing - of the final product? Share your thoughts over in the forums.

All comes down to price, if they are priced keenly I could see myself running a three monitor setup from a powered USB hub.

*Doesn't see advantage of one less cable*

Will their normal monitors be this energy efficient?
They could be good in a corporate environment, if the power saving can justify the cost.

It says usb powered, but does the video go over the usb cable as well or did they hide the vga/dvi cable in the picture?

I hardly dare ask how much the twin USB cable will cost... :p

This is no use if you have a powerful graphics card

I bet it's not 120hz....

The only application I see here is for HTPC (if it's a touch screen) or low powered workstations (Word, Internet Explorer)

Awesome, I'd happily run a third monitor to place Word documents or other similarly mundane things; no matter how much this costs, it's gotta be cheaper than buying a similar sized model and a TripleHead2Go, or buying a second graphics card. At least that's assuming USB is the only connection, I wish the linked article had a higher resolution picture so I could read the little features sign next to the monitor.

Samsung have got a series of USB driven monitors out at the moment, so I assume these will be USB powered and USB driven.

Would be a dissapointment if they were not.

Well, over here it's written as the data goes over USB too.

the panel needs just 6.3W of power, which it draws from two USB 2.0 ports. It also draws display connection from one of the two USB ports.
So i'd guess it'd struggle with any sort of video/gaming :( (if it can handle it at all without turning into a slideshow)

I don't know about that. There was a Twin USB cable bundled with my cheap ars HDD case when I bought that. so I couldn't image it would cost much more than a standard USB cable.

I'm guessing this is USB 3.0 exclusive, then.

6.3W/5V=1.26A

USB 2.0 would require three cables to meet the spec.

Does power supply change with usb3 or only data rates?

More energy efficiency is always welcome. Especially as this will negate another power converter and use the relatively efficient pc power supply rather than a power brick.

Needs to be single USB. Can they do roughly half the screen with a single cable?

This could open up for some nice mod possibilities in the future...

OMG FAIL FAIL FAIL.
This should have been USB3!!!!!!!!!!!!!!!!!!

I mean would not USB3 be much better for this with higher data rate and higher power!!??!!
It would also be one of the first inventive uses that woul push USB3 out quicker.
God I do hope Samsung see this and comes out with a USB3 version.

I wouldn't waste two USb ports just for the display. It's good that they've improved power efficiency, but they could just have done that on a normal monitor.

900mA (0.9A) vs USB 2.0's 500mA.

Reading the comments and using your brain fail. It almost certainly is USB3.

Just for faster charging abilities im tempted to get a usb3 PCI-e now lol

I wonder how many of these you could add to your PC at once? Could you just fill all your usb sockets with these monitors to have say 6 of these monitors all working at the same time as extended desktop? Cos normally you'd need a special graphics card or adapter to add more than 2 monitors. Just asking out of interest cos I doubt anyone will be planning on doing that!

While it sounds good that this doesn't use much power, the low resolution for the size, along with poor light and contrast mean this wouldn't be the best monitor for games or movies.

Going to be keeping my eye on this! I already run two monitors and I'm wanting a third, but I don't want to have to fork out nearly £300 for the monitor and card to drive it!

This definitely has some useful applications, a monitor that will run on any PC regardless of it's VGA connectivity, plug and play and swap between machines with relative ease!

Also I just realized that you could in theory make a computer with no gpu at all and still be able to hook this up and get an image! This could be useful for the initial setup of a small low footprint system that has no need for a grafixcard, even an integrated one.

this would be great for mobile solutions like Car computers, one less cable to route and manage would be very welcomed when it comes to wiring a PC into a car. Im planing on using Double Sights USB power 10" screens in my car for that reason.

While mmo gaming, this would be a great addition to have around for static maps, or guides on certain areas.
