What is AMOLED?
AMOLED means Active Matrix Organic light emitting diode
Active matrix (AM) OLED displays stack cathode, organic, and anode layers on top of another layer – or substrate – that contains circuitry. The pixels are defined by the deposition of the organic material in a continuous, discrete “dot” pattern. Each pixel is activated directly: A corresponding circuit delivers voltage to the cathode and anode materials, stimulating the middle organic layer. AM OLED pixels turn on and off more than three times faster than the speed of conventional motion picture film – making these displays ideal for fluid, full-motion video.
The worldwide AM-OLED market will grow to US$4.6 billion by 2014, representing a CAGR of 83.3 percent, up from US$67 million in 2007, according to iSuppli Corp. In terms of shipments that is expected to grow to 185.2 million units by 2014, rising at a compound annual growth rate (CAGR) of 84.2 percent up from 2.6 million units in 2007.

Two primary TFT backplane technologies, poly-Silicon (poly-Si) and amorphous-Silicon (a-Si) are used today in AMOLEDs.

Why is AMOLED the future?
High Perceived Luminance
Perceived luminance is 1.5 times higher than that of conventional lcd display.
The contrast of an AMOLED is unbelievable it offers clear images and readability in any environment.
Wide Viewing Angle
High color gamut and no color shift by viewing angle and/or gray scales.
More vivid and dynamic image quality is realized in moving pictures.
