What is OLED?
From this article: http://1src.com/?m=show&id=469
OLED display is a self-luminous display that does not require a back-light, offering high contrast ratio, a quick response time and wide viewing angle—all in a package slimmer than current LCD modules. To enhance this display, Sony has employed its unique Super Top Emission technology for outstanding brightness and greater color gamut. These translate into image quality and clarity that could previously viewed only on CRT (cathode ray tube) displays.
The new 3.8-inch (or 9.7 cm) screen measures 2.14 mm thin, and makes it possible for users to enjoy a variety of high-quality content such as TV programs and digital still images without compromising on the viewing experience.
My th55 screen is enough good for all that, oled screen is not necessery for usual pda user, so i'm getting that why sony did make that screen ?
OLED are cheaper to be made
OLED is better because...
1)better viewing angle
2)almost 3X brighter
3)cheaper to make
4)better color reproduction
5)no backlight needed
6)better battery life
Yup - Aside from the fading issue, OLED/LEPs are better than LCD in every way, technically and economically!
But if this is the case, I don't get anymore why oh why has Sony priced the new VZ clie way way much more expensive than any existing PDA (in the PalmOS area, at least)...
Its not like the specs are anything to rave about...
as for the battery life, how OLED stands in energy consumption comparison to other PDA displays? any information on this?
OLED has better battery life because OLED dont need a backlight, are auto-iluminated.
Well that's easy - It's new!
Think about how much the UX and NZ cost when they first came out!
Also, while they are cheap to make, I bet Sony has had to pump a lof of R&D money in to overcome the fade issues, costs which Sony will no doubt want to recoup ;)
Come to think of it, if the screens are cheap, after it fades, replace it with a new one. ;)
Good point ;)
But you forget one thing: It's a Sony! (Cheap? Sony? BWHAHAHA! :D)
But OLEd only holds c. 2 Years
Here is a good website about OLED:
Organic displays are in their early stages. Ayone in the digital game is sinking a pile of money into this area, include the likes of Kodak. The challenge remains in the mfg process. The ability to sublimate organic materials onto glass in a predictable way, with reasonable yield rates is where the challenge is. If they could work that out, any OLED display would be very cheap. The challenge with anything that is "organic" is it has a half life...The benefits of illumination with low levels current (ie low power consumption) due come at a cost. That cost is simply the half life of the organic matter.
