If you recall we recently praised the promise of better HD displays with sets using the organic LED (OLED) technology. It turns out that the accolades may be a bit premature for at least one manufacturer. Tests by an independent research firm called DisplaySearch have revealed that the Sony XEL-1 model has some problems.

There is noticeable degradation of brightness after about 1000 hours of use. This projects to losing about half of the original quality by 17,000 hours which is about five years of typical use. Sony says that the brightness issue has been addressed in its latest version of the TV.

Given the current high cost of the technology, it’s pretty safe to assume that these won’t be finding their way into local family rooms anytime soon.
