Types of Mobile Phone Displays

06 July 2012 – More often than not, consumers base their purchase decisions of smartphones based on the screen size, neglecting the actual technology that powers their displays. Below is a simple guide that explains the commonly seen mobile phone display technology that is available in the market right now
TFT LCD Display
Thin film transistor liquid crystal display (TFT LCD) is essentially a variant of liquid crystal display (LCD), and is by far the most common display technology used in mobile phones. With the technology being cheaper to manufacture over time, TFT LCD displays are mostly nowadays found in low-end devices.
The drawback to TFT LCDs is its narrow viewing angles and poor visibility under direct light. In addition, TFT displays consume more power, making it battery unfriendly.
Super LCD (SLCD)
As implied in its name, the SLCD is an upgrade over the LCD technology that is based on. The SLCD is said display warmer colour tones and improved colour definition over that seen on AMOLED displays. HTC currently employs this technology in the HTC One X.
IPS (in-plane switching) LCD displays are yet another direct upgrade to the normal TFT LCD displays. It removes limitations of the TFT LCDs by offering wider viewing angles, and at the same time consuming much less energy.
As a result, it also costs more to develop this technology, and is thus seen only in higher end devices.
- True HD IPS LCD
The upcoming LG Optimus LTE 2 has a 4.5–inch True HD IPS display, which is touted by the company to offer “advanced resolution, brightness and clarity and shows colors in their most natural tones, as they were meant to be seen.”
Retina Display is the term used by Apple to brand their high resolution (640x960 pixels) IPS LCD display technology, first seen in the iPhone4. The reason the technology is dubbed Retina Display is due to its individual pixels not being discernable by the human eye, allowing the images and text to look sharper.
OLED (Organic Light Emitting Diode) has the advantage over standard LCD display technologies due its better colour reproduction, faster response times, wider viewing angles, and light weight design The technology will be employed in Panasonic’s yet-to-named smartphone.
There are no major differences between OLED and AMOLED (Active-Matrix Organic Light-Emitting Diode). Active Matrix is a technology that allows for the controlling of individual pixels. In essence, AMOLED screens pretty much incorporate all the traits of an OLED display - good colour reproduction, faster response times, wider viewing angles, higher brightness and light weight designs.
- Super AMOLED Display:
Super AMOLED displays are being developed by Samsung, and is currently said to be the thinnest display technology in the market. Maintaining virtually every trait seen in it predecessor, the Super AMOLED display is said to be much more responsive than an AMOLED display. Initially seen on the Samsung Galaxy S II, the technology has since been succeeded by the HD Super AMOLED display that is on the Samsung Galaxy S III.
