TFT screens are all passé now and the upcoming smartphone models do not feature it.    

IPS In Plane Switching


IPS LCD’s are considered the best among all! They consume less power as compared to the TFT ones and offer better view even if seen from the edges of the screen. IPS screen is available in hi-end smartphone models. IPS LCD screens are legible in sunlight and have wider viewing angles. The screen consumes less power and emits true to life colors.

OLED (Organic Light Emitting Diode)

OLED screens produce better colors, offer wider viewing angles, impressive color contrast and have faster response time if compared to an LCD screen. An OLED screen is slim, light in weight and does not require a backlight to illuminate the display and thus consumes less power. OLED screen is on the expensive side of the range scale.  

AMOLED (Active-Matrix Organic Light-Emitting Diode)





AMOLED screens do not need a backlight as each pixel on the screen is backed by an LED. High brightness, low power consumption, slim frame, light weight screen are some major highlights of such screens. These screens are available in hi-end smartphones as they are costlier than the LCD screens. The screen produces pleasing and true to life colors.   

SUPER AMOLED (Super Active-Matrix Organic Light-Emitting Diode)

Super AMOLED is an improved version of the basic OLED/AMOLED screens. Samsung used the term for marketing purposes with a few improvements. It has the thinnest display screen, its light weight and produces great color contrast and lifelike colors.  

Retina Display 

Retina display is not a different technology it’s another name for IPS LCD with an LED backlight. The term was used by Apple as a promotion tool.
