Types of Smartphones Displays.

Almost all of us are fimilar with smartphones or simply mobiles. The smartphones plays a vital role in our life today weather it is browsing, playing, reading, watching movies, etc. The displays of smartphones are that part through which an user can interact with its device. These days many types of displays/panels are used in smartphones.

 These include
• TFT (Thin Film Transistor)
• LCD (Liquid Crystal Displays)
• TFT LCD (Thin Film Transistor Liquid Crystal Display)
• IPS LCD (In Plane Switching Liquid Crystal Display)
• OLED (Organic Light - Emitting Diode)
• AMOLED (Active-Matrix Organic Light Emitting Diode)
• Super AMOLED (Super Active-Matrix Light Emitting Diode)
• Retina Display
• Haptic Tactile Touchscreen

So now you have fimilar with the types of displays. Lets know in detail about them.

1.TFT (Thin Film Transistor):

The short form of TFT is "Thin Film Transistor". It is a type of flat panel display screen, in which each pixel is controlled by one to four transistors. The TFT screens gives out a good resolution but is power hungry and have less good viewing angles. They also are not a good displays for doing work in direct light or direct sunlight. They are less expensive than LCDs, TFT LCDs and IPS LCDs.

2.LCD(Liquid Crystal Display):

The LCDs (Liquid Crystal Displays) consists of a matrix of liquid crystals. These Liquid crystals do not emit light themselves and are depend on some kind of back-light like LEDs to illuminate the diplay to produce pictures. So due to this property they provide a good visibility in direct sunlight as compared to other displays. Only demerit of these displays are that they do not produce true colours. They also consume more power and thus they are not battery friendly.  They are more cheaper than any other displays. Generally, LCD displays are thicker than IPS LCD and OLED or AMOLED displays. The viewing angles are not as good as IPS-LCD, OLED and AMOLED. Now a days, these types of displays are impossible to see even in lower end smartphones. Both whites and blacks are not good as compared to IPS-LCD, OLED, and AMOLED.

3.TFT LCD(Thin Film Transistor Liquid Crystal Display):

 The full form of TFT LCD is Thin Film Transistor Liquid Crystal Display. These are the most common types of displays across mobile phones. These TFT LCD screen offers a better image quality and colour reproduction as compared to normal LCDs of earlier versions but their limit is that they have a very narrow viewing angles. They also have a poor visibility in direct sunlight or normal light. Also they consume more power than IPS LCDs and thus are not battery friendly. But they are very cheaper than any other displays.

 Now a days the use of these types of display have become very less so these types of displays can only be found in some very cheaper devices.

4.IPS-LCD(In Plane Switching Liquid Crystal Display): 

The IPS-LCD displays are the upgrade version of LCDs. These displays provide a better colour reproduction and viewing angles as compared to LCDs, TFT and TFT LCD. They also contain the layout of LCDs. These displays are good for viewing in direct sunlight. These days they can be found in both high end, mid range as well as in some lower end smartphones. They are thicker than OLED and AMOLED but thinner than LCDs. They are much more expensive than TFT or LCDs and TFT LCD but are cheaper than OLED and AMOLED. The whites are more better visible than black. They have lower power consumption as compared to TFT LCD, TFT and LCD.

5.OLED(Organic Light Emitting Diode):

OLED uses organic LEDs which emits lights itself. So in this case every pixel has its own light as and can be turned off separately thus viewing a good and more deeper blacks. The OLEDs produce real life colours. It is a newer technology. The OLEDs have faster response time than LCDs, good viewing angles, higher brightness and very light weight construction. They are very thin and consume less power and this increases the battery life.

In OLEDs a layer of organic material (carbon based material) is put between the two conducting layers (simply an anode and a cathode),and then these layers are sandwiched between a glass top plate (seal) and a glass bottom plate  (substrate).

When an electric current is applied to its conducting sheets, electro-luminesxent light is produced directly from the organic material. The amount of brightness and color can be vary depending on the amount of electric current supplied.

6.AMOLED(Active Matrix Organic Light Emitting Diode):

These displays have all the properties of OLED displays and are found in basically higher end smartphones. They also have a brilliant color reproduction,  fine viewing angles, light weight design, less power consumption and higher brightness as well as deeper blacks than normal OLED displays.

7.Super AMOLED(Active Matrix Organic Light Emitting Diode):

Super AMOLED displays are also known as SAMOLED. These are the advanced version of AMOLED displays which contain touch sensors on the display itself thus reducing the air gap between the screen and display. This makes then more thin and light weight than OLEDs and AMOLEDs. These Super AMOLED displays are also much more sensitive and responsive than OLED and AMOLED displays. These displays are found in some top of the line smartphones like Samsung galaxy note 8, google pixel, apple iPhone 7 and 7 plus, etc.

8.Retina display:

 The Retina display is not a type of display but a term used by the Apple comapany for its high resolutions  (640×960 pixels) displays in iPhone 4. They called it Retina displays because it's pixels cannot be identified by human eyes separately.  So this makes the display more sharp and produce brilliant colors.

9.Haptic/Tactile touch screen:

This type of technology is used by Blackberry and Nokia  for their touch screen smartphones.  In this technology, an user get a haptic feedback when it touches it's mobile screen and this makes them to coform that weather they have done any mistake or not. Haptic technology has improved at a great level time to time for users satisfaction.
