When we hear the word screen, there are lots of things come in our minds like Mobile screen, smartwatch screen, television screen, computer screen or others thing which shows us the output in a picture way. In the last few years, not only gadgets but also many changes have been made on the screens. At present there are different kinds of screen options are available for every gadget especially for smartphones and PC’s. Here are the names of some old and currently running screens types…
- Cathode ray tube display (CRT)
- Electroluminescent display (ELD)
- Electronic paper, E Ink.
- Thin-film transistor display (TFT)
- Organic light-emitting diode display (OLED)
- Digital micro shutter display (DMS)
- Plasma display panel (PDP)
- High-Performance Addressing display (HPA)
- Digital Light Processing display (DLP)
- Interferometric modulator display (IMOD)
- Liquid crystal display (LCD)
- Light emitting diode display (LED)
- Organic Light-Emitting Diode (OLED)
- Active matrix organic light-emitting diode (AMOLED)
All these screens have their own features and specialties. And if we talk about the present time, so OLED and AMOLED are two of them which are the most used and liked screen of present time. Both of these are the developed and latest version of the LED screen. But both the screens have different qualities and compatibilities with different devices so let’s take a short introduction to both of the screens…
OLED stands for “Organic Light-Emitting Diode”, which is the latest technology of LED screen. All the new smartphones and smart televisions are using OLED screens for better picture quality, iPhone and Samsung Galaxy series are the best examples of this. OLED Screens are costly but much better than LCD Display because LCD Display needs the backup lights for bright the liquid crystal and creates the visuals on screen but OLED Screen doesn’t need any kind of backlight for creating visuals on screen, it generates its own lights. It is thinner and brighter than the other lights and it gives you the higher and perfect contrast ratio in low light conditions. OLED display featured with accurate colors because of its extra white pixel. The technology of OLED divided into two different parts PMOLED (Passive Matrix Display) and AMOLED (Active Matrix Display). So that’s all about OLED screen now let’s see how it works.
How OLED Technology Works
So there is a thin film of organic compound which placed between two conductors and when the electric energy passes through it, it generates the lights and that’s how OLED display works.

AMOLED screen is a type of OLED screen but it based on the latest technology and that’s the reason AMOLED screen is much better than OLED screen. The Full name of AMOLED screen is “Active Matrix Organic Light Emitting Diode”. AMOLED is a next generation High technology based Display. It is much brighter, more accurate and thinner than OLED screen. The reason behind its success on Smartphones and Smart TV is that it consumes less energy than the others. It provides you the picture quality with Accuracy. It also divided into two parts which are the new SAMOLED (Super Active-matrix organic light-emitting diode) and the second one is S plus AMOLED screen (Super Plus Active-matrix organic light-emitting diode.). So let’s how this technology works..
How AMOLED Screen Technology Works
AMOLED display stack cathode, organic, and anode layers on top of another layer that contains an electronic circuit. The pixels are defined by the deposition of the organic material during a continuous, separate “dot” pattern. Each pixel is activated directly without any extra rotation, A related circuit delivers the voltage to cathode and anode layer to stimulating the middle organic layer. AMOLED pixels activate and off quite 3 times quicker than the speed of standard flick film, creating these displays ideal for fluid, full-motion video.
