Choosing a Laptop Screen
Choosing a laptop screen (monitor) depends on the user, basically an average laptop owner considers the screen size and resolution as top priorities while gamers, product designers, graphics designers and individuals who need high definition picture quality consider high color quality and refresh rate as priority.
Some terms to note
- Screen Resolution: A screen display resolution is usually defined by the relationship between the horizontal and vertical pixel, a pixel being the basic unit of a digital picture. The common 1920 X 1080, also known as 1080p as well as the 4k resolution (3840 X 2160) and above are typical examples. Graphics processors basically manipulate and alter memory to accelerate the creation of images in a display device. A higher screen resolution means better picture quality. The resolution is generally affected by the size of the screen.
Although monitor screen technology plays a major role in display qualities, the panel of a monitor screen determines its colour precision. Monitors basically have three display types: twisted nematic (TN), vertical alignment (VA) and in-plane switching (IPS). All these are Liquid Crystal Display (LCD) technologies.
2. Nematic: Although this display type provides smooth motion, the colour precision is poor and oftentimes tint when viewed at a specific angle. This type of display is usually recommended for budget-conscious individuals and well experienced gamers. The TN display type has faster refresh rate which means, the amount of time it takes a pixel to change its color is shorter, therefore it can display images faster within a short time period.
3. Vertical alignment: One major advantage of this display is good colour display. However, slightly blurry motion and weaker viewing angle (to some extent) can be experienced. This display type is usually enjoyed by slow-paced game players.
4. In-Plane Switching: This has the most precise colour display as well as great viewing angles, it is known to be the best display type in monitor screen technology, although there are slight challenges while using it in a dark room, as there are slight issues with black colours in this type of display while in a completely dark environment. This type of display panel is also the most expensive of the three display types.
The terms and concepts above should well considered when choosing the best laptop screens suitable for a specific purpose with a balanced compromise on all factors, taking consideration of both the cost, color display and overall image quality, be it for personal use, work, gaming purposes e.t.c
The science of these technologies have been left out for simplicity sake. On a later article, a deeper delve into the science of the subject of Display technologies might be dealt with for our more technical readers.
