OLED HDTVs 40-inches and larger to be available in 2012

Many smaller electronic devices like high-end smartphones and PMPs are already coming with OLED screens. These screens consume less power than LCD counterparts making for longer run times. Another benefit is that an OLED panel tends to offer better colors than a comparable LCD.

LG has announced at the FPD International 2009 show in Yokohama City, Japan that it will be launching a new 15-inch OLED TV on the market by the end of 2009. The set reportedly will have a resolution of 1366 x 768 and a peak luminance of 450cd/m2. The panel will use a bottom emission type and is constructed of low-temperature polycrystal Si-TFTs crystallized by a high-temp process.

LG has plans beyond 15-inch OLED screens with 20-inch and larger panels coming in 2010, 30-inch and larger coming in 2011, and 40-inch and over panels in 2012. LG OLED marketing and sales VP Won Kim said, "Forty-inch and larger OLED panels will be fairly expensive in 2012, but they will be available in the market."

Consumers will have to wait until 2016 to see the price of OLED panels drop below the price of LCD panels. The reason is that a stable supply of large OLED panels at a low cost is unavailable today. Big challenges for OLED panels today include driver elements, organic EL materials, and the sealing process.

Kim said, "We will be able to use a low-temperature polycrystal silicon with the sixth-generation size glass substrate." He continued, "However, for 40-inch and larger panels, we have to use the eighth-generation size glass substrate. Therefore, we have to develop equipment that can deal with an SPC process at a temperature of more than 700°C."

According to LG, its OLED panels will use florescent materials until 2011 and then move to phosphorescent materials after 2012. When 2016 rolls around OLED panels will be 20-30% lower in material cost and have an equivalent yield to LCD panels today. In 2012, the OLED panel will have a 50% higher material cost and 30% lower yield than LCD panels.

I believe they still do, but it's more manageable now. Again, it's one more reason why OLED isn't plastered everywhere.

The Zune HD is probably the first major, large scale application of OLED screens. Hopefully, the investment into OLED tech will help develop the tech even more.

Pioneer has been using them on their car stereos for a while now.

OLEDs have been used in small screen applications for a good while, but these are ones where the number of hours where they are active may be limited (where I've noticed them anyway), and in that car stereo application, having the blues get dimmer may not even be overly noticable.

Having a TV set that runs for only 10,000 hours before dying might be thought to be unacceptable, but if that's an auto radio display that may be considered quite a lot of driving time (and quite a few miles).

I have a Cowon S9 and owned it for about a year and the screen is holding up to it's factory state. Even though it's a PMP I love to leave the screen on because it's just that beautiful (AMOLED) even if it's just wallpaper.

I also just purchased a ZuneHD and I'm loving that as well and it has a bigger screen for better web browsing.

The funny thing is that Samsung supplies the AMOLED screens to these manufacturers which explains the similar if not same quality. The glass can be problematic though (it's for scratch protection) as it's not very good in sunlight.

I had a Creative Labs mini MP3 player with regular OLED and that was viewable outdoors but small.

There are over 10 models of cell-phones from various manufacturers (including NOKIA, SE, LG, Motorola, Samsung) that use oled screens.

So whats the deal now with the blues? Have there been advances in blue diode lifespans or are they selling us something that will have reddish/green tint after a few years?
