(Transparent OLED) An organic LED display technology that is entirely transparent. Regular OLEDs use a transparent anode layer that faces the user and a cathode layer that reflects light back. The TOLED uses both a transparent anode and cathode, which enables a see-through device.|
Using TOLED technology, OLEDs can be constructed as a stacked OLED (SOLED), in which separate red, green and blue layers are stacked on top of each other. A stacked OLED provides precise color alignment because the R, G and B pixels are directly on top of each other rather than side by side as with regular OLED and other display technologies. See OLED.
