Undertanding all the types of smartphone displays.

Hey yo friends
Most of the times when we look at the specifications of a smartphone , We see some stuff like it has an IPS-LCD or a AMOLED display , first thing comes in our mind is that "what the hell does these displays are ? ". Now you can easily understand these specs too and can yourself decide the pros and the cons of the smartphone.
After Understanding the Chipsets , CPU and the GPU of a smartphone , we are moving on to the types of smartphone displays.
Guys I have basically collected this information from around 4-5 websites, understood it and simplified it and then posted it here.   


Friends , Here are the most common types of Smartphone displays you would often come across.

1. TFT-LCD type display

Here TFT stands for Thin film transistor - Liquid crystal display. These are the most common type of display units across mobile phones. 



TFT-LCD offers better image quality and better resolution as compared to the earlier LCD displays but their limitation lies in poor viewing angles and poor visibility in direct light or sunlight.
Large TFT displays consume more battery life and thus are not battery friendly but since they are cheap , they are used in lower end smartphones and feature phones.

2. IPS-LCD type display

IPS stands for In-plane switching . IPS-LCD types of displays have better viewing angles , more resolution and consume less battery ,  Thus are far more better than TFT type displays

3. Resistive-Touchscreen LCD type display

Touchscreen LCD displays are of two types : Resistive and capacitive
Resistive touchscreen displays basically contain 2 layer of conducting material and a small gap between them which acts as a resistance. 




Whenever we touch our finger or a stylus at a point on the screen , the 2 layers meet thus making a circuit . The information is passed to the mobile chipset which processes the interaction and thus completing the action.
Resistive touch screens are less responsive because they often require a stylus to work upon them , thus they are used only in lower end smartphones and touch feature phones.

4. Capacitive touchscreen LCD type display

This is the second category of the type of touch LCD display.
Capacitive touchscreen technology consists of a layer of glass coated with a transparent conductor like Indium tin oxide . When a capacitive touch screen is touched by our finger an interruption is created in the screen's electrostatic field (which is measured as the change in capacitance). This information is passed to the phone's chipset and thus action is completed.



Capacitive touchsceens are much better and responsive to human touch when compared to resistive touchsceens and hence the user experience for touch is much better with capacitive touchscreens. Capacitive Touchsceens are used in most of the higher end smartphones.

5. OLED type display

OLED stands for Organic Light Emitting Diode and is a newer technology for displays of mobiles and monitors. In OLED technology a layer of organic material (carbon based) is sandwiched between two conducting sheets (an anode and a cathode), which in turn are sandwiched between a glass top plate (seal) and a glass bottom plate (substrate). When electric pulse is applied the two conducting sheets, electro-luminescent light is produced directly from the organic material sandwiched between. Brightness and color can vary depending on the electric pulse.







 OLEDs are much better compared to LCDs because of their exceptional color reproduction, blazing fast response times, wider viewing angles, higher brightness and extremely light weight designs.
Nowadays they are mostly used for curved displays.

6. AMOLED type display


This term is basically pronounced as AMO-LED. 
It stands for Active matrix-Organic light emitting diode. AMOLED displays are a type of displays for mobile.
AMOLED stands for Active-Matrix Organic Light-Emitting Diode. AMOLED displays are a type of OLED displays for mobiles and are rapidly gaining popularity in top end smartphone segment. 
AMOLED screens have all the attributes of an OLED display like brilliant color reproduction, light weight, better battery life, higher brightness and sharpness and light weight designs.

AMOLED displays are now getting into main stream and most of the latest higher end smartphones are now coming with AMOLED displays. If you can shell out a little extra, our suggestion is to go with AMOLEDs over TFT LCDs.


6. SUPER-AMOLED type display


Super-AMOLED display is a type of touch display originally developed for Samsung high end smartphones. 




Super AMOLED display is built with touch sensors on the display itself, as opposed to creating a separate touch sensitive layer (as in capacitive touchscreen). This makes it the thinnest display technology on the market.

7. RETINA type display

Retina type display was first used by Apple for its newly released at-that-time Iphone 4 for its high resolution (640x960 pixels) IPS-LCD screen.



They call it the Retina display because its pixels cannot be individually identified by the human eye, thus making the display super sharp and brilliant.

8. GORILLA GLASS
Gorilla glass is a special type of alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use. 




Many companies like Motorola, Samsung and Nokia are now using Gorilla Glass to make their mobile displays more durable and reliable. It is always better to go for a smartphone with Gorilla Glass for that added protection and peace of mind.
