Types of Smartphone Displays - AMOLED, TFT LCD, OLED, IPS

Smartphone Display is the very first thing which user sees when they buy a new smartphone from the market. This is because the display screen interacts with the software and does various things. However, the display screen has evolved and today humans have reached the milestone of making flexible displays. There are many types of screens that are used in mobile phones.

1. AMOLED – (Active-Matrix Organic Light-Emitting Diode)

Amoled is a type of OLED displays for mobile phone which are becoming very popular in the top-end smartphone segment. AMOLED displays can show us many things that are present on the OLED screen such as bright color reproduction, lightweight, good battery life, adequate brightness, etc.

2. Super AMOLED Displays

Super AMOLED displays adopt AMOLED displays and are mainly developed by Samsung. Super AMOLED is built with touch sensors placed on the screen itself, rather than creating a separate touch-sensitive layer (as in the capacitive touch screen). This makes it the thinnest screen technology on the market. Super AMOLED displays are currently only present on Samsung devices, but more phones could use the technology in the future.

3. TFT LCD – (Thin Film Transistor technology)

The TFT LCD is the most common type of display found in smartphone devices. The TFT LCD screen gives you good image quality and higher resolutions compared to previous generation LCD screens, however, at narrow viewing angles and indirect light or sunlight there is poor visibility.

4. OLED - ( Organic Light Emitted Diode )

This is the newest technology for mobile screens and monitors. As far as OLED technology is concerned, you will find an organic material that is placed between two conductive sheets (an anode and a cathode), which are also placed between an upper plate of glass (seal) and a lower plate of glass (substrate). The time that passes or an electrical pulse is applied between the two conductive sheets, the electroluminescent light is produced directly from the organic material sandwiched between them.

5. IPS-LCD  (In-Place Switching)

IPS LCD Displays has more features like lower consumption and wider viewing angles which provide much more battery life. IPS-LCD is more expensive than TFT LCD which is why they are only on high-end Smartphones. A higher resolution(640 x 960 pixels) of IPS LCD is found in  'Apple iPhone 4' which is called 'Retina Display' because of its brilliant picture quality.
