OLED is a new technology, the thin, efficient and lightweight screen. OLEDs are composed of organic materials and luminescent OLED does not require backlighting and filtering, the LCD screens. OLEDs are so easy to do and, in fact, may be more flexible and transparent. OLEDs are also very effective, and businesses, LED lighting – OLED a “bulb” are effective and those that paved the way for the great light of new concepts.
There are two types of OLEDs in displays – PMOLED and AMOLED. The difference is in the driving electronics – can be a passive matrix (PM) or active matrix (AM).
With passive-matrix OLED, the display is governed by the power-lines and columns. If you click on line number and column xy, pixels on the cross – and light. Whenever you can only after a pixel. So you must, and very quickly. They do it in a certain order, and create the desired image. It is something that the interleaving, the system in the old tubes, but the checks are carried out pixel by pixel.
PMOLEDs are very easy and cheap to build, but they are limited to small sizes (up to 3 “, as a rule). The image is a bit complicated (because of the row / column method). In addition , electricity consumption is not as though AMOLED.
Another AMOLED driver electronics – for each pixel is directly. AMOLED is more expensive and more difficult to create, but can be used for larger screens (prototypes are currently up to 40 “) and are very common.
The first OLED screen on the market for products used PMOLEDs – the MP3 player has been sub-screens of mobile phones and radio-bridge for cars. The screens were small and, in general, with only one or two colors. If AMOLED panels started in the years 2007 and 2008, we saw these great mobile video screens, digital cameras, mobile phones and even the largest OLED TV shows.
PMOLEDs are still very popular – there are more MP3 players sold today PMOLED for LCDs. But for larger screens AMOLED technology is best, and grows much faster than PMOLED watch. Of course, for larger screens, TV monitors, laptop or PDA, AMOLED is the only option.
Today, there are several businesses, technologies, in order to bridge the gap between PMOLEDs and AMOLED – offers a kind of hybrid system. The promise is that they are both displayed and easy to power larger screen effectively. We still have to wait and see whether these technologies actually ads work. One such technology is the dialogue SmartXtend.
