Analysis of Sony's OLED TV Reveals Design Innovations

The XEL-1 organic light-emitting diode (OLED) TV released by Sony Corp of Japan in December 2007 has a display only 3mm thick. In addition to its innovative design, another key selling point is the display performance. We measured and evaluated the display performance with the help of a panel engineer, and came to understand the difficulties that Sony faced in overcoming the drawbacks associated with using OLED panels in TVs, and how it made the best use of the superlative image quality that OLED panels offer.
