OLED displays are made from organic (carbon based) materials that emit light when electricity is applied. OLEDs can be used to create displays - and these are bright and efficient with a fast response time and a wide viewing angle. OLED display can be made very thin (the thinnest prototype is 50 microns...) and even transparent or flexible.
AMOLED: Active Matrix OLEDThe term AMOLED means Active-Matrix OLED. The 'active-matrix' part refers to the driving electronics, or the TFT layer. When you display an image, you actually display it line by line (sequentially) as you can only change one line at a time. An AMOLED uses a TFT which contains a storage capacitor which maintains the line pixel states, and so enables large size (and large resolution) displays.
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.
Why is AMOLED Best
High Perceived Luminance
Perceived luminance is 1.5 times higher than that of conventional lcd display.
Contrast ratioThe contrast of an AMOLED is unbelievable it offers clear images and readability in any environment.
WIDE VIEWING ANGLE
