Transparent OLED

Transparent OLED (or TOLED) is an organic light-emitting diode that uses a proprietary transparent contact to create displays that can be made to be top-only emitting, bottom-only emitting, or both top and bottom emitting (transparent). TOLEDs can greatly improve contrast, making it much easier to view displays in bright sunlight. This technology is used in Heads-up displays, and may be used in future head-mounted displays to create transparent HMDs.
