Screen Features Explained

By April 5, 2018Prestigio

If all the tech jargon surrounding smartphone, Tablet, and laptop screens leaves you feeling confused. You aren’t alone. Prestigio wants to make display specifications easy to understand.

We’ve created this simple guide to making sense of screen features.

Screen Size

Measured in either inches or centimetres. Screen size is fairly self-explanatory. It is good to know, however, that ultra-portable devices screens usually feature a wide aspect-ratio feature that allows for adjusting viewing as well as zoom features to enlarge what you are viewing.

Touch Screens

Prestigio Smartphones, Tablets, and 2-in-1 devices all have visual displays that also perform as touch screens.

Touch Screen – This type of screen is resistive: meaning it will react to a specific input device such as a stylus but not human touch.
Capacitive Touch Screen – This screen will receive input from a specialized device &/ the touch of a user’s finger or hand. This means you do not need to depend on a mouse, trackpad, or external keyboard but can navigate and perform tasks solely on-screen.
Multi-Touch Capacity – This Capacitive Touch Screen is the most advanced thus far. It is capable of receiving input from not only one but two or more multiple contact points at the same time. Prestigio is proud to offer this within the majority of our devices.

Screen Resolution

Resolution refers to the number of pixels displayed on the screen.

Pixel – A pixel is the absolute smallest point or ‘dot’ of a screen display. Together pixels make up the lines and images that you see on your screen.

Pixels concentration determines how clear and bright images and text appear on your screen. It impacts the amount of fine detail you can distinguish. Pixel Count is listed as two numbers. These are the number of pixels displayed across (horizontal) the screen and the number of pixels displayed down (vertical) the screen. i.e. 1280 x 1040.

High Definition – High Definition (HD) defines a screen with a high number of pixels. HD qualities mean that a screen will have crisp, well-defined images, and be capable of displaying a very fine level of detail. HD screens come in 720, 1080i, and 1080p.

Colour Gamut – This refers to colour reproduction meaning the total number of colours that a screen can display. This becomes important to Professional Creatives dealing with high-end graphics.

Screen Types

Screen-type refers to the technology used to create what you see on the screen. Various manufacturers may add proprietary elements such as extra coatings to the screen and choose matte or gloss finishes. It is not possible to determine a ‘best’ screen across the board. Individuals should determine what will suit their usage requirements and not over-invest in high-end specifications which may not serve their needs.

LCD Screens

The overwhelming majority of device screens feature some version of Liquid Crystal Display (LCD) technology. LCD utilizes a source of light behind the screen (usually lots of little LED lights) to backlight and illuminate on-screen pixels that make up screen and text. LCD offers the advantage of reproducing natural colours and vivid colours with less energy output so batteries can last for longer, it can display images sharply and can be easy to see in outdoor settings when natural light is bright.

TN/TFT LCD- Twisted Nematic (TN) or Thin Film Transistor (TFT) are the same thing. While still possessing LCD technology they have some improvements on original LCD screens. They are the most common type of screen used in small portable devices. They are popular because they are good across the board and offer affordability, predictability and great features. They offer super-fast refresh rates (utilized by 3D gamers) and improved colour quality. Drawbacks may include diminished viewing angles (so they are best viewed straight-on), minimized colour gamut, and differing qualities of contrast ratio’s.

IPS LCD- In Plane Switching (IPS) technology has been developed to improve further on existing LCD technologies. In particular it addresses some of the weaknesses of TN/TFT including creating a higher colour gamut and extending viewing angles. An IPS LCD screen ensures that pictures appear bright and colourful from all perspectives. They boast great contrast ratio’s but they still lag a little behind TN/TFT when it comes to refresh rates. IPS screens are a fantastic choice for applications used by Professional Creatives.

OLED Screens

Organic Light Emitted Diodes (OLED) are unlike LCD in that they do not require a backlight. In an OLED screen, each pixel generates its own light using hydrocarbon chains. The display results equal ultra-contrast so that dark colours are extra deep and light colours are extra bright. The major benefit of OLED screens is that they can be less energy intensive than other types of displays. A significant drawback is that their expected lifetime is shorter than LCD technology.

w

AMOLED

Active Matrix Organic Light Emitted Diode (AMOLED) is a hybrid screen that features TFT LCD and OLED technology together. This creates very quick response times with less energy consumption than required in other types of screens. This type of screen is rare in portable devices and mainly utilized in large entertainment screens such as TV’s.

Screen Protection

Screens need to be protected from impact and foreign matter such as liquids and dust. Prestigio designs sturdy devices with built in protective features such as incredible Gorilla Glass. Gorilla Glass 3rd generation technology that offers heavy duty scratch-protection and impact resistance. We also offer affordably priced impact resistant quality protective cases and screen-covers so you don’t have to compromise when it comes to protecting your device.
