While buying a mobile device, TV or any device which has a display screen, we mostly keep an eye on other things instead of checking which screen technology has been used in that device.
Now, one of the main reason behind this ignorance could be, that we don’t have proper knowledge of which screen technology does what and which is better?
So, here I have brought a complete solution of such issues.
Read below and you will understand which display screen technologies are currently being used and why?
TFT – LCD (Thin Film Transistor – Liquid Crystal Display)
The TFT-LCD is one of the oldest display, which is currently used only in very low budget smartphones.
Now, why it is used in only low budget smartphone, the first reason is, it is very cheaper than other technologies.
But if we talk about efficiency, then you should know that this display consumes a lot of energy, hence your battery will drain quickly. The contrast range in the display is not something we can say amazing. And also it is very thick display, hence phones containing TFT display, are very thick.
IPS – LCD (In-Plane Switching – Liquid Crystal Display)
This display technology is one of the best display technology yet made.
While making IPS-LCD, researchers gave special attention on colour reproduction, viewing angles, thickness.
Now, colour reproduction in IPS display is very vibrant and accurate, hence you will feel no issue in of colour accuracy.
Viewing angles and sunlight visibility is comparatively very much impressive in this display.
With the invention of IPS technology, thin phones started hitting the market.
Super LCD (Super Liquid Crystal Display)
Super LCD is an improved version of TFT display, but it is not as efficient as the IPS display.
IPS-LCD is the best display in the LCD series.
OLED (Organic Light Emitting Diode)
OLED displays are highly efficient (in many ways) than LCD technologies because it is lighter in design, contrast range is great, colour reproduction is excellent, wider viewing angle and above all, it consumes very less power.
This display technology gives a very thin display, which eventually also is lightest and hence improves the mobile experience.
AMOLED (Active Matrix Organic Light Emitting Diode)
Getting a step ahead, OLED technology is improved into AMOLED. The AMOLED screens have control over each screen pixel individually and remaining thing is as same as OLED display.
The interesting thing is, Retina Display is just a name given by Apple, nothing else.
Retina Display is just an IPS display, which offers a pixel density more than 163 PPI (Pixel Per Inch).
In another word, you can understand that it is just a marketing strategy followed by Apple to fool (at some extent) the people thinking that they are buying something more efficient than IPS or AMOLED.
So, every phone which has PPI more than 163 and has an IPS display is Retina Display.
Comparison Between AMOLED & IPS-LCD
Colour Accuracy – IPS-LCD produces more accurate colour than AMOLED but colour produced from AMOLED is eye-friendly.
Brightness – AMOLED is brighter display than IPS-LCD.
Sunlight Visibility – IPS-LCD is more clearly visible in the sunlight that AMOLED.
Power Consumption – AMOLED requires less power as compared to IPS-LCD.
Thickness – AMOLED can produce the thinnest display than IPS-LCD.
Cost – IPS-LCD is cheaper comparatively than AMOLED.
