Laptop Screen

Types of Laptop Screen
Although they may all seem the same to the untrained eye, there are in fact several different types of laptop screen.
You may have heard of terms like LED, LCD, TFT and OLED, but what do they actually mean?
How can knowing the difference help you when choosing a new laptop or considering a replacement laptop screen?
Here are some basic explanations of the key terms associated with laptop screens.

Resolution
Measured by the number of pixels in a row and column, the higher the resolution of the LCD screen, the better the quality of the image displayed.

LCD
LCD screens are the most common type of screen in laptops, with laptop manufacturers choosing to fit them in their laptops for a variety of reasons. They provide a good median standard in terms of quality, price and performance. Due to being mass produced, the quality is good, but the price is lower than other types of laptop screen. The technology relies upon liquid crystals made from plastic or glass, and are created and activated by sending an electric current through them.

TFT LCD
Based on the LCD screen, TFT LCD screens employ active matrix display technology which is an improvement on passive matrix display technology.
The improved and smoother display result in a superior image quality, screen response time and image clarity to the LCD screens, but the price is higher.

LED
LED (Light-Emitting Diode) screens have made the step up from mobile phones to laptops with relative ease.  Developers were keen to improve LED screen technology for the transition to laptops, due to the greater viewing angles, and brighter and sharper image capabilities. Due to being newer to the market and not so mass produced, there is still a while before the price will drop, however, it is cheapest to produce, so the price should fall in the long term.

OLED
OLED (Organic Light-Emitting Diode) screens are a step forward from LED screens and made their breakthrough to the laptop screen market in 2010. Utilising organic material as opposed to conductive crystals produces better quality images, and the lack of need for a backlight improves battery life.
