What is amoled?
AMOLED is a display technology used in some of the most popular mobile devices available today, including various Android handsets and tablets that. AMOLED stands for “active-matrix organic light-emitting diode” – a rather complex term that you don’t have to remember as long as you know how it works.
How do amoled displays work?
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. AMOLED 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.
Pentile amoled
PenTile or PenTile Matrix is a technology that refers to subpixel arrangement in AMOLED displays. PenTile screens have a RGBG (Red-Green-Blue-Green) pixel layout – see image below – compared to regular displays that rely on an RGB-RGB pattern. The advantage is that PenTile displays can offer a higher resolution utilizing less pixels, but the disadvantage is that image is not as sharp as you’d expect it to be exactly because less pixels are involved. Of the AMOLED variants mentioned above, only the Super AMOLED Plus displays offer an RGB-RGB arrangement, and therefore are capable of offering a crisper image.
OLED Advantages:
Slimmer: The biggest adavantage of OLED screen is that it is slimmer than LCD display. While LCD and Plasma displays could be few inches thick, OLED advantage is that it is only few millimeters thick.
Faster: Another advantage of OLED is that it has much better response time than other displays. So these screens often provide better user experience. This advantage will lead great use of OLEd screens in mobile phones and other handheld devices where fast response time is usually required.
Efficient in Energy: OLED displays consumes less energy as compared to LCD displays and other display screens. No backlit is required in these screens which is the biggest OLED advantage for use in portable gadgets.
Good for Eyes: Another great advantage of OLED is that it pts less stains on eyes and hence are eye soothening. These screens provide better viewing experience because they have better contrast, brightness and color aspects.
Large Viewing Angle: Viewing angle is always an issue in flat screens. But with theadvent of OLED displays, viewing angle could be as large as 170 degree because they produce their own light which increases their viewing angle.
Flexible: Now you get displays which you can bend. This is possible only through theadvent of OLED screens.
Durability: Another great advantage of OLED is that it is more durable than traditional screens. There chance of getting broken is comparitively less to LCD screens and other displays.
Low Cost: The price of OLED screens may be much higher now but it will come down as the technology becomes popular. OLED screens could become cheaper than LCD screens in coming time.
