The 'White Magic' LCD module featuring the newly-developed 'RGBW method'

Sony has announced via its webpage the development of a new type of LCD display that uses either half as much power as current same-size LCD displays, or the same amount of power, but doubles the brightness. Called WhiteMagic, the new LCD screen, currently just 3 inches diagonally, achieves these results by employing a third, white pixel to create images on a screen.
For the most part, most LCD displays use just three backlit pixels - Red, Green and Blue (RGB) to create one dot of color on the screen; the various colors are produced by filtering the light that comes from behind each of the three pixels to varying degrees, creating a mix. With this new panel, however, Sony has introduced a fourth pixel, which is pure white, and serves to double the brightness of each dot, not by increasing the power of the backlighting, which would necessitate the use of more battery power, but by simply allowing more viewable white light to pass through the White pixel which when combined with the filtered Red, Green or Blue pixels, results in twice as much light passing through each dot on the panel, resulting in a brighter image overall.
Previous attempts to do the same thing resulted in the Red, Green and Blue pixels being overpowered by the White pixel with a resultant washed out look (less contrast) on the panel. Sony has solved that problem by developing an algorithm, which runs in a special chip, that it says allows for images as sharp and clear as current RGB displays.
The display, which due to the extra pixel in each dot means 1/3 more pixels in total (640*480*4=1.2 million of them) are used, comes in two modes; standard mode is where the panel dims the backlighting to reduce battery power requirements by half, producing an image that is approximately the same brightness as current displays. Outside mode is where the backlighting is returned to “normal” producing an image that is twice as bright as regular LCD displays.
Devices with such a panel could help users with the familiar problem of having difficulty seeing what is on their phone or camera screen when outside in the sun. Conversely, by dimming the backlighting when indoors, the panel should greatly extend battery life.
Sony says the new panel should be ready for shipment by October, possibly in time for camera or phone makers to add the new panel to their wares in time for Christmas.
Ping!................
Ok.....
I’ll be the first.....
“THAT’S RACIST”!!!!!!!!!!!

Sony is a great little company. Small by Japanese standards, but very innovative.
Betamax...................
Brilliant!
Betamax was the superior format, it lost out because at the time, recording time was the primary motivator. Beta was used by the professional video industry for many years.
That said, Sony has come up with plenty of weird stuff that never quite caught on, like their digital audio tape format. Even sony cameras now allow the use of SD cards as well as the proprietary Memory Stick format.
I read once that what really sealed Betamax’s fate was the porn industry chose the other format to standardize on.
Greatest advertizing slogan of all times - It’s Sony, no baloney.
I thought Larry Bird was White Magic.
“Sony is a great little company. Small by Japanese standards, but very innovative.”
Isn’t Sony behind the 0bama/Seal Team 6/bin Laden propaganda movie to be released in October 2012?
...but very innovative for innovation sake.
Invented BETA and SUPERBETA far supperior to VHS, failed on market.
Invented ELCASSETTE, far supperior to compact cassette, failed on market.
Invented Minidisc, failed on market (except Japan).
Invented SACD, phased out deliberately by Sony.
Invented their own PC (PSX?), failed.
Invented memory stick, no one is using it.
And so on. Too many flops to remember them all.
Only fool hopes to achieve different result without adjusting behavior.
Sony's problem are not brilliant engineers and designers. Problem are villanous managers and shareholders.
Sony tries for more than 30 years to corner the market. Closest they got was Trinitron TV many years ago and PS3 today. They try to get royalty from the entire world. And they fail miserably.
Some of their activities border on illegal, like deliberately infecting customer PCs with their malware, or having lax attitute towards customer data.
SONY and APPLE Inc. would be marriage made in heaven.
I just hung a 50 inch hdtv above my fireplace and it looks hideous. They should create a border-less screen which can mimic the color of the wall so that when not in use it is invisible or at least camouflaged.
