Sony is going to release in a few months a Clie that will include an OLED screen. This will be the first handheld to use a display of this type.
OLED (organic light-emitting diode) displays take advantage of the fact that some organic compounds glow when an electrical current is applied to them. This means there is no need of a backlight, as the individual pixels provide their own light. This allows OLED screens to be thinner and lighter than standard LEDs. Colors also tend to be more vivid.
According to Yomiuri On Line, Sony will release a Clie this spring that will use an OLED display that is three to four inches, which is roughly the size being used in its NX series now.
Just as with LCDs, OLEDs come in two forms: passive matrix and active matrix. It is not known at this time which type Sony will use in its upcoming model.
Sony has long been on the cutting edge of research and development on OLED screens. Until now, passive-matrix OLEDs have used too much power to be used in handhelds, while active matrix OLEDs in sizes large enough to be used in a handheld couldn't be manufactured reliably. Presumably, the company has solved the problems with one or the other of these two types if it is ready to ship a large OLED screen to consumers.
If this Clie is going to ship this spring, it is also likely to include Palm OS 6, the next generation of this operating system. However, nothing else is known about this model at this time.
