(Active Matrix Organic Light Emitting Diode)

There is another type of O.L.E.D. called A.M.O.L.E.D. or Active Matrix Organic Light Emitting Diode.  This type of O.L.E.D. is commonly used on smaller devices such as telephone screens, MP3 screens and televisions.  The current maximum size is around 40 inches.

Here is an illustration of this Active Matrix Organic Light Emitting Diode technology:


One feature that makes A.M.O.L.E.D better than O.L.E.D. is the they have a quicker refresh rate.  That means that images and graphics on the screen will appear to move without any blurring or distortion.

For the first time in 2012, A.M.O.L.E.D were used in consumer devices such as smart phones, MP3 players, digital camera and televisions.  Current demand for A.M.O.L.E.D.s is very high, that makes it costly and as a result makes the end consumer product high.  But as the supply catches up with demand, it will make these product cheaper for the consumer.

According to UBI Research, 89 million A.M.O.L.E.D. displays were shipped in 2011.  And it is projected that this number will increase by at least 70% in 2012.

The other popular type of O.L.E.D. is the P.M.O.L.E.D or Passive Matrix Organic Light Emitting Diode.  This type of O.L.E.D. uses a passive matrix and is not as commonly used as the other types.  One issue is that P.M.O.L.E.D. are limited by size and resolution.  They are cheaper than A.M.O.L.E.D.s and are used in devices like smart phone and secondary displays in cameras and P.D.A.s or Personal Digital Assistant.
Like anything else, as the price of P.M.O.L.E.D. reduce in price, so will the cost.  If they can reduce the cost of P.M.O.L.E.D., it will make O.L.E.D. a more common item.  This is because it will last longer and have better visibility in bright light or sunshine.
