OLED (Organic Light Emitting Diode) display has more superior quality than traditional Liquid Crystal Displays because it’s not created only from glass substrates but also on bendable plastic materials, which makes it also useful for the other applications. One of the more interesting uses is that these new displays can be folded or rolled, without the display being damaged. They are also lighter and thinner than LCD displays offering better quality.
Japan Display, in a joint venture among Sony, Toshiba and Hitachi, is all set to begin mass production of OLED displays for the next two years.
There is also a rumor that in future Apple will launch an iPhone with OLED displays made by Samsung, which already makes AMOLED (active-matrix organic light-emitting diode).
But the main constraint for the OLED display is that it’s more expensive so the likely hood of having cheap displays for smart phones in the next few years doesn’t seem high. Though when smart phones do come with OLED screens they’ll definitely be of better quality.
