TFT-LCD
TFT is Thin Film Transistor technology. The TFT LCDs are one of the most common types of display that are used across devices. TFT offers a better overall image quality and somehow higher resolutions as compared to earlier versions of LCD displays, but it has narrow viewing angles and poor visibility in direct sunlight. Since it is cheaper to manufacture so you can see it on more number of budget devices and low end smartphones.
IPS-LCD
IPS-LCD
IPS means In-place Switching. If you start comparing TFT alongside IPS, then IPS is better display with wider viewing angles and lower power consumption which automatically gives improved battery life. However these are costlier than any normal TFT LCD so you will find this on high end smartphones. One interesting fact is Apple iPhone used a resolution of 640 * 960 pixels version of IPS LCD and they named it as Retina Display because of its brilliant picture quality.
AMOLED
AMOLED is Active Matrix Organic Light Emitting Diode, this technology has grown in recent years, and particularly used by Samsung for its products. This kind of screen consists of a thin layer of organic polymer which lights up when a current is provided to it. These screens are extremely thin, have a simple construction, and don't require any backlight, which saves battery life in phones and tablets.
Super AMOLED
These are even advanced version of AMOLED displays, again developed by Samsung. These displays are built with touch sensors on the display itself, ending the need of separate touch sensitive layer. So this makes it the thinnest display tech on the market. They are more responsive than AMOLED dsiplays.
OLED SCREENS
Organic Light Emitting Diode is considered to be better for battery life as it doesn't use any kind of power to create black. These displays produce vivider colors than LCD and are much brighter and has great viewing angles. Touch response is also very good in these displays. As a consumer we need better performance, vivid colors and much brighter screens. So now OLED displays are "best choice". But these have a shorter life span
Benefits of OLED screens:
- Light weight
- Great responsiveness
- Bright and bold colours
- Better definition than most LCD screens
- Very thin
- Less battery hungry in many cases than other screen types.
Drawbacks of OLED screens:
- Age quickly and can lose colour clarity for reds and blues
- Expensive, used in high-end smartphones, and are inaccessible to those on a budget.
