Touchscreens Used with Smartphones


iPhone 5, Samsung S4, Windows Phone 8, Samsung Galaxy Tab


Basically this is a knowledge based article. It can just enrich your knowledge about display technology. And I think you will enjoy this. I'll try to provide you a brief idea about the screen technology used by the leading cell phone manufacturers. 


By this time you should know there are different types of display technologies such as LCD, LED, TFT, Retina etc. But how many of you know the details of each type? To be honest, I didn't have much idea about these before reading an article in a newspaper. Then I decided to write about smartphone screens on Marks PC Solution. I've also gathered information on display technology from different sites. 



TFT LCD Display (Thin Film Transistor Liquid Crystal Display)

This is the most widely used display technology at present. TFT LCD technology ensures the clear view. It is better than old LCD technology to view High Quality pictures and video. 

This type of display is relatively cheaper. So it can be used in low-priced phones too. 

But this technology has some limitations too. You can't operate your phone in sunlight. Your display will be almost unseen when you're in daylight. And this type of display consumes too much battery. You should keep the display off as much time as possible. 



IPS LCD Display (In-Plane Switching LCD)

IPS LCD is better than TFT LCD Display Technology. No matter how you wanna see it. You can get a clear view from any angle. It doesn't consume much power. That's why it saves your battery power. 

Manufacturing cost is little bit higher and used with medium-priced cell phones. 



Resistive Touchscreen Display (Don't Call it RTS!)

I've searched Google by RTS. Actually it has no short form. You should call it Resistive Touchscreen Display. 

In this technology, there are two layers in the screen. And there is a minor gap between the two layers. Whenever the first layer get your touch, the blank space between two layers blends and pressure the second layer. Immediately the processor gets signal. Thus Resistive Display Technology works. 

You can operate the phone using fingers or stylus. But using a stylus will be more comfortable. 



Capacitive Touchscreen Display

If you wanna operate your phone with fingers then capacitive display is more comfortable than resistive display. As made for operating with fingers, you can't use stylus or something else to work with capacitive display. 

This display ensures fast response time. Manufacturing cost is also high. This display is used with high-priced smartphones. 



OLED Display (Organic Light Emitting Diode) 

Most of you maybe familiar with only LED - Light Emitting Diode. More than a year ago, I wrote a post about the difference between LCD and LED. OLED is the improved version of LED technology. 

OLED is a high quality display technology for cell phones and monitors. It gives you a bright look. This type of display is very light and viewing angle is excellent. It supports 16 million colors and reponse time is very short. 

OLED display consumes less power and thus it saves your battery. 



AMOLED Display (Active Matrix LED)

Active Matrix OLED is a display technology that is used with mobile devices and televisions. It is actually an improved version of OLED. 

One of the great features of this display is the viewing capacity in sunlight. Users can see the screen in daylight without any problem. AMOLED ensures vivid picture with super sensitive screen. 

As the manufacturing cost is relatively higher, this type of display is used with high end mobile devices. 



Super AMOLED Display

Next to the AMOLED is Super AMOLED. It is nothing but the improved version of AMOLED developed by Samsung. This technology is used with the galaxy series devices. 

Super AMOLED includes the following features:

  • Light and thin
  • Vivid Display
  • Faster Reponsive Capacity
  • Less Power Consuming

Retina Display 

The most modern version of smartphone screen is the Retina Display, which is a combination of IPS LCD and Backlit LED technology. As developed by Apple, this type of display is only used with iPhone. 

It is a so high resolution display that you can't see the pixels with blank eyes. That's why it is named as Retina Display. 

Retina Display is very sharp, vivid and clear. 



Heptic Touchscreen Dispay

Nokia and BlackBerry are using this type of display technology. This display is capable of identifying the touch accurately. Thus it enables users to work with touchscreen comfortably. 

This display is reliable, comfortable and great for typing. And it's very popular among the users. 



Gorilla Glass Display

Maybe you can guess something about this display. Yes you're right. This display is made for rough and tough use. 

Gorilla Glass is very hard and durable display. It keeps your display out of scratch. Even it can protect the screen from hammer. Many cell phone manufacturers are now using Gorilla Glass in their devices. 


Here I've just discussed about 10 types of displays. And these have many variations. If you'd like to know more then search Wikipedia.
