Many have heard about the XEL-1, which Sony claims to be the first commercial TV based on OLED technology, but less well known is that the device apparently has a few major downsides—and not just because its display is only a measily 11" across. According to EE Times, the XEL-1 also has worrying design defects.
Citing research firm DisplaySearch, EE Times says the TV's active matrix OLED (AMOLED) implementation has a much shorter lifespan than what Sony quotes in its specifications: allegedly only 5,000 hours for white colors and 17,000 hours for "typical video image." Worse yet, EE Times adds that the panel is victim to "differential aging," which causes blue, red, and green luminances to shrink by 12%, 7%, and 8%, respectively, after just 1,000 hours—that's about a month and a half of continuous use. EE Times adds, "DisplaySearch analysts claim that the Sony display is significantly inferior in many ways to other current AMOLED designs."
