All OLED TV Reviews

This is a short review on the screen tilting function of the Sony XEL-1 OLED TV. As this model is best suited for a desktop or similar close up viewing, having the organic panel tilt for optimum viewing is a must. The video below demonstrates this capability.

I’ve got my hands on a Sony XEL-1 OLED TV for a review. I’ve got to say it’s pretty impressive. I could best compare it to a concept car, the kind you see at auto shows that don’t look that practical. The Sony XEL-1 is just that, a product that showcases the latest technology in it’s field. I’ll have impressions of the XEL-1 itself, photos and video clips over the next little while. Hope you’ll come back and check it out.

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

Dupont and Dainippon have announced a partnership to develop a new OLED manufacturing process.

“The companies also have signed an agreement relating to their intention to bring together the elements needed – materials, technology and equipment – to mass produce OLED displays, delivering higher performance at a lower cost.

“The flat panel display market is about US$100 billion annually and growing. DuPont is applying its science to make possible more vivid displays that are lower cost than current LCD displays,” said David B Miller, group vice president of DuPont Electronic & Communication Technologies.

The companies are developing integrated coating and printing equipment for the fabrication of OLED displays from solution, an approach which is unique in the industry and can significantly reduce manufacturing costs for OLED displays.

DuPont brings to the alliance its distinctive small molecule-based OLED solution materials and proprietary process technology from which excellent performance has been obtained in testing. Dainippon Screen has developed a unique printing technology, called nozzle printing, in which the OLED materials can be printed accurately at very high speed.”

This is good news and helps to balance out the bad news on the Sony XEL-1 lifetime issues.

According to an fairly negative OLED TV review by DisplaySearch, the first commercial OLED TV, the SONY XEL-1, does not seem to have the lifespan claimed by Sony. In addition, several other characteristics do not outperform either LCD or plasma TV models currently available.

It turns out that the RGB architecture is very sensitive to the image, and it has a 5,000-hour lifetime for white and a 17,000-hour lifetime for the typical video image–well below the Sony’s published specifications, according to the report.

Moreover the panel suffers from differential aging: After 1,000 hours the blue luminance degraded by 12 percent, the red by 7 percent and the green by 8 percent, said the report. (more…)
