Super AMOLED vs Super LCD3

SAMSUNG GALAXY S7 and HTC Desire 826 are the best examples of  two types of latest mobile screens namely Super AMOLED  and Super LCD3.

TFT-LCD

TFT-LCD screen is the most popular screen available on the mobile phones.  TFT-LCD stands for thin-film transistor liquid crystal display

 Displays with  dull colours have narrow viewing angles and  if you look at them from sides we could not recognise what is on the screen.

High quality LCD screens will have bright accurate colours and have visibility from any angle.

LCD screens requires light behind them which shines through the pixels to make them visible. As a result they don’t give the quality of AMOLED technology.

The LCD undergone number improvements namely Super LCD, Super LCD2 and Super LCD3 similar to AMOLED screen enhancements. 

AMOLED

AMOLED or Active-matrix organic light-emitting diode displays don’t need a backlight-each pixel emits its own light-so phones with AMOLED displays can be thinner than LCD mobiles. 

AMOLED technology is based on organic compounds that offers best image quality on very low power usage. This kind of screens utilizes very little electricity even for watching videos on black screens compared to the dark grey of LCD screens.

AMOLED screen manufacturing is very hard compared to LCD manufacturing as it has to go through number of stages till its transformation to the functional screen.

SUPER AMOLED SCREEN

This is derivative of AMOLED screen .  During manufacturing capacitive touchscreen technology is being included so that it is not required to overlaid later. The power usage can be further reduced than AMOLED and is capable of increased brightness.

SUPER AMOLED PLUS

This most advanced AMOLED screen provides much sharper crisp images equivalent to LCD screens by making considerable changes subpixel construction.  

IPS- or in-plane switching smartphone screens are characterised by vibrant colours and excellent off-axis viewing angles. The images are viewable from any angle.

With IPS, the crystals are aligned horizontally to the screen and electrical field is applied between each end of the crystal molecules. As the liquid crystal molecules are not adhered to the lower glass substrate, so move more freely into the desired alignment.

Based on the functionality of the screen it can be generally divided in to two. 

Capacitive touch screen

Capacitive touch screens are more responsive to user action and allow for the use of multi touch technologies. Capacitive touch screens simply transfer a small amount of energy to users body when it is on touch with the screen. With the help of app. the  mobile will calculate which specific area of the mobile have changed its charge.

Resistive touch screen

This technology consists of two thin metal layers under the glass screen of the mobile, which collects location data when pressed together. The user has to press hard by exerting more force on the screen. This will result in less responsive user experience
