Choosing Your Smartphone Touchscreen Display by Amaechi5(m): 12:07am On Jul 22, 2015
Now we are in a market where there are so many smartphones with different display and sometimes we get confused on choosing the one we like.
Display type is one of the major things to consider when buying a smartphone, so when you are under the sun or a very bright light you can still operate your device without having any problem looking into your phone.

We want a display with high pixel density for clearimage, as less glare as possible and as bright as it can get for those sunny days, and as vibrant colours for joyable watching experience and It's good to always go for best especially if you can afford to.

If you are confused with the best display you want in a smartphone, just sit back and continue reading.

Touchscreen Display

A touch screen display is a display screen that is also an input device. The screen is sensitive to pressure; a user interacts with the device by touching pictures or words on the screen with a finger or soft object.

Types of touchscreen display

Resistive touchscreen: Resistive touchscreen displays are composed of multiple layers that are separated by thin spaces. Pressure applied to the surface of the display by a finger or stylus causes the layers to touch, which completes electrical circuits and tells the device where the user is touching.
Resistive type touchscreens require much more pressure to activate than capacitive touchscreens. As it is now there is no new smartphone with this kind of display anymore.

Capacitive touchscreens: Capacitive touchscreen displays rely on the electrical properties of the human body to detect when and where on a display the user touches, by so doing the display can be controlled with very light touches of a finger and generally cannot be used with a mechanical stylus or a gloved hand.

LCD: Liquid Crystal Display is the most common screen display in the world, and we have different types of liquid crystal displays (LCD). From cheap, low budget display technologies with dull colours and poor viewing angles, to high end ones, capable of presenting extremely vivid, natural colours with wide viewing angles.

LCD screens produce some of the most realistic colors you can find on a screen, but might not offer as wide of a contrast ratio (darker darks and brighter brights) as an AMOLED screen.
We also have different types of LCD like TFT LCD, IPS LCD, S-LCD, SUPER LCD, SUPER LCD 2 etc.

TFT LCD: thin film transistor is a type of LCD flat-panel display screen, in which each pixel is controlled by from one to four transistors. The TFT technology provides the best resolution of all the flat-panel techniques. One disadvantage of TFT is that it has poor viewing angles and outdoor visibility under direct sunlight. They ought to consume more power, and.drain battery very fast. TFT screens are sometimes called active-matrix LCDs. The cost of producing TFT screen is low and that's why it's mostly seen on low-end smartphones.

IPS LCD: IPS stands for in-plane switching. An IPS-LCD is a type of thin display that offers better viewing angles than TFT-LCDs. IPS-LCDs feature two transistors for each pixel and viewing angles are wider, outdoor visibility is better and should consumes less power.
Production cost is a little higher, that is why we encounter them in high end phones.

Super LCD: This differs from regular LCD by removed gap between glass and display panel, making better viewing angles, less glare and nicer look, picture appears closer to you, feels more natural and warmer. Super LCD is very popular in HTC smartphone phones though was actually produced by Sony.

Super LCD2: this is just an updated version of super LCD with a very little features but almost the same function.

OLED: Organic Light Emitting Diode (OLED) display technology is much better as compared to the LCD display technology because of its excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely light weight designs.

OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity.
The plastic, organic layers of an OLED are thinner, lighter and more flexible than the crystalline layers in an LED or LCD.
There are two types of OLED touchscreen, AMOLED and Super AMOLED touchscreen.

AMOLED TOUCHSCREEN: AMOLED stands for Active Matrix Organic Light Emitting Diode. A step ahead of OLED screens, the AMOLED screens can control each pixel individuality while maintaining the properties of a OLED panel.

AMOLED screens have all the attributes of an OLED display like brilliant color reproduction, light weight, better battery life, higher brightness and sharpness and light weight designs.
Production cost of AMOLED touch screen is very high and that's why is mostly seen on high end smartphones.

Super AMOLED: Super AMOLED display technology is an advanced version of AMOLED display. Super AMOLED display is built with touch sensors on the display itself, as opposed to creating a separate touch sensitive layer (as in capacitive touchscreen), this makes it the thinnest display technology on the market.
Super AMOLED displays are also much more responsive than other AMOLED displays and developed by Samsung.

Retina Display: Retina Display is a term used by Apple for its high resolution (640 x 960 pixels) IPS LCD (with backlit LED) used by them in iPhone4 in June 2010. They call it the Retina display because its pixels cannot be individually identified by the human eye, thus making the display super sharp and brilliant.

Haptic/Tactile touchscreen: Haptic technology has been used by Blackberry and Nokia Lumia phones for their touchscreen smartphones targeted towards enterprise market. This technology provides a tactile feedback on a touch action on the screen thus providing an immediate and unmistakable confirmation to the user.

Gorilla Glass: Gorilla Glass is a special alkali-aluminosilicate glass shield with exceptional damage resistance that helps protect mobile displays from scratches, drops, and bumps of everyday use. Many companies like Motorola, Samsung and Nokia are now using Gorilla Glass to make their mobile displays more durable and reliable.

And that's is, if you want to buy a smartphone today consider the touchscreen display and the touch itself and i will candidly advice you to choose between IPS LCD or Any of the OLED touchscreen with Gorilla Glass from 2-3 though smartphones with such are usually high end device.

OP you didnot mention IGZO display made by sharp. It offers vibrant colours,wide viewing of angles and less battery consumption,(it was used in meizu m1 note and meizu m2 note etc)

My old LG G PRO had a Tru Hd Ips Lcd display, and Yes, I could operate it with my gloves on.

Rocking Super AMOLED on my infinix zero2. Little wonder the phone is very light with a highly durable battery not withstanding its low battery capacity

Chinko phones still use resistive touchscreen. It is one of their characteristics.
