This is a subject that hasn’t received much attention. Usually, OLED TV reviews mention the attributes of the OLED displays that differentiate them from LCD or Plasma screens.

Amazing contrast levels, fantastic color and impossibly thin screens are many of the things that promise to make TV viewing, at least in the future, so much better. There are still production difficulties to overcome and the problem of offering a consumer ready product at a price point that is at least semi-competitive with LCD or plasma TV.

However, OLED TVs are not perfect. With the first OLED TV available to consumers, the XEL-1, Sony warns about screen damage due to image retention. This has been a problem in the past with plasma TV but apparently this is still something that OLED manufacturers are dealing with.

The XEL-1 manual states the following;

“Prolonged display of still images over time may cause permanent image retention. Avoid displaying images that cause image retention and take the following measures to protect the screen.”

The following are images that Sony says may cause image retention. Continue reading »

 

Sony has responded to the claims of decreased longevity of its XEL-1 OLED TV. The XEL-1 recently received a number of negative OLED TV reviews after it was claimed it would only last around half the 30,000 hours stated by Sony before fading.

Practically speaking, this won’t have any effect on the average viewer as 30,000 hours will last you a good number of years.

Register Hardware has a reply from Sony on these findings. Read more at reghardware.co.uk

 

Taking OLED TV development yet a step further, Sony has displayed an even thinner version of the XEL-1 at the Display 2008 show in Japan.

According to audioholics.com;

“The new display was recently shown off at the Display 2008 expo trade show in Japan, where Sony also debuted a new version of its $2500 11-inch XEL-1, the world’s first mass-produced OLED TV. In this unit, the display panel “glass” measures just 0.3mm thick, about 1/4 the thickness of the prior model. We’ll be terribly impressed when the pricing drops by about 1000% and sizes go up to 42-inches or more. Until then, it’s fun to watch and wait.”

 

Although this won’t have a real effect on Sony OLED TV production until 2009, it’s an indication of where Sony is heading:

Sony has announced plans to invest approximately 22 billion yen (US$204 million) to strengthen its OLED panel production technology. With the investment, Sony intends to accelerate the shift to medium- to large-size OLED panels.

Sony began researching OLED technology in 1994, and has since positioned OLED as a future-generation display technology. In December 2007, Sony launched the world’s first OLED TV, “XEL-1″ in Japan.

In order to advance the shift towards medium- to large-size OLED panels, Sony has decided to invest towards the further development of production technologies starting from the second half of the fiscal year ending March 31, 2009. Sony will reinforce its TFT and EL (electroluminescent) layer coating processing facilities at Sony Mobile Display’s Higashiura factory, and plans to implement this production technology during the fiscal year ending March 31, 2010.

We’re looking forward to OLED TV reviews on the larger sized Sony OLED TV’s in 2009.
