FEATURES
Contrast ratio 50,000:1. Toshiba's final versions of SEDs will have a contrast ratio of 100,000:1.
Response time 0.2 milliseconds.
Brightness of 450 cd/m2.
180º Viewing angle.
Viewable in Bright room.
The SED produces light directly on its front surface.
Provides dynamic color expressions, a sharp picture, and perform faster video response.
It is possible to create screens of more than 40" in size that are only several centimeters thick.
It can be used in Mobile device display.
Low power consumption.
Longer life expectancy
FUTURE SCOPE
SED will be the next generation display technology in the nearby future.
SED will enter production and compete with LCDs in all areas.
All of the claims made by the backers of SED you would think that there should be no reason to buy any other type of display.
As far as the specs go, this is one hot technology.
