the organic LED commonly known as the OLED is a great display technology. OLEDs emit light in a way quite different than the LCD displays we see today. if u have an LCD display and u change your viewing angle the display changes. so u have to sit right infornt of it. and the guy sitting at about an angle of 170-180 degrees will just be seeing a black screen. this is not the case with OLEDs. OLEDs emit light in all directions. and OLEDs are thinner than LCDs.
there are a number of variations of OLEDs like the FOLED that can be folded and the TOLED, well i dont remember what that does :lol:
i dont know about organic emissive displays. maybe its a new technology. or maybe just a new name for OLEDs.
