AMOLED stands for Active Matrix Organic Light Emitting Diode. AMOLED is a display technology OLED (Organic Light Emitting Diode). OLED is a solid device that consists of thin films. The films containing organic molecules that can produce light when powered.OLED is used as a screen in a device with a higher acuity levels and relatively low power consumption. AMOLED is issued by Samsung, a technology company based in South Korea (Seoul). As one of the largest technology companies in the world, Samsung launched the innovative touch screen AMOLED-based technology that became the first AMOLED touch screen. AMOLED technology is a form of development from the previous screen, known as Thin Film Transistor (TFT). This technology is the result of a combination of OLED technology and conventional active matrix TFT LCD. AMOLED is a form of development of ordinary passive OLED screen, which can turn any pixel with efficiently and directly. AMOLED technology has touch functionality (touchscreen) directly, rather than through the second layer on top of the screen. The new method is done through the addition of sensors to the organic cells of the LED. Touch interface is able to increase the thickness of the screen reaches a thousandth of a millimeter, so it will reduce the sharpness or dim the image, as if mounted in two panels.
AMOLED display has a brightness level (brightness) high in appearance. AMOLED technology packed RGB adjustment feature, which can make the color of the photo or video is more stable, so it looks brighter and sharper. This technology has a low level of energy consumption or saving power, so that power consumption is minimal, and the battery can last for a long time. This technology is able to save 40 percent more power than others. Rate thinness of the screen reaches 0.001 mm. In addition the screen is even claimed to produce better black levels than others, though seen from the sun directly, the screen still looks bright and clear, and the color is still bright. AMOLED screen also does not require backlighting that has the ability to regulate how much pixels, with lower power consumption, even in large sizes. In addition, this screen also has a deeper contrast ratio than most other LCDs. The uniqueness of the shape AMOLED screen is a screen is able to adjust the brightness of the screen automatically. AMOLED is made faster response times when the phone turns on and off positions. Thinness and flexibility of the material used in this screen technology making factories can make the screen in varying sizes, from small to giant size though. For example, layarTV Plasma reached 150 inches in size to the smallest size on the phone. Besides the other advantages of this technology compared to LCD technology is that the AMOLED technology, to be seen by the human eye does not require a backlight light further.
weakness of this screen, that is making the screen is still quite pretty complicated. In addition, because the technology is still new, the price of devices that use this technology are also relatively expensive. Although the AMOLED screen offers a tempting range of sophistication, but it is not easy for the vendors to adopt AMOLED, because it has a component AMOLED prices are more expensive than the components on the previous screen. This, of course, make the vendors to re-think. That is the reason why some technologies, such as smartphones are relatively rare form of tablets equipped with AMOLED screen and still survive with a TFT screen, the goal is to reduce the selling price to the consumer. However, some vendors are able to produce their own AMOLED display technology is easier to apply this screen, such as Samsung and LG.
