In the process of using a laptop, it is vital that the screen looks “comfortable”, and there are many factors that affect the display of the screen, and in this article we will sort through them one by one.
Screen size
The common sizes of notebook screens today include 11.6 inches, 13.3 inches, 14 inches, 15.6 inches, 16 inches and 17.3 inches. If you often carry your laptop on the go, give priority to 14-inch or smaller size; if you usually keep your laptop in a fixed place such as home, office or dormitory, 15.6-inch or larger size can make you look better.
Display ratio
The display ratio of the laptop screen is mainly 16:9 and 3:2, are 14-inch notebooks, with 16:9 display ratio screen can make the body become more long and thin, and more suitable for watching videos; with 3:2 display ratio screen can shorten the length of the body, which is conducive to compressing the width of the upper and lower bezel screen to enhance the screen ratio, and this display ratio is also more suitable for office, a screen can display more More content.
Resolution
The higher the resolution of the laptop screen, the finer the screen display, but also brings the text and icons become too small and other problems, you need to use the Windows 10 display settings “zoom” function to enlarge to 125% ~ 150% to see clearly. For the majority of ordinary users, the FHD level of resolution is sufficient, more than 2K resolution is more suitable for professional design and graphics class workers.
Refresh rate
The standard refresh rate for laptop screens is 60Hz, and a few gaming notebooks are equipped with 120Hz, 144Hz or even 240Hz refresh rate screens. These ultra-high refresh rate screens are often called “gaming screens” by gamers, which can effectively reduce the blurring of dynamic images and screen tearing and other problems, making the gaming experience smoother and more fluid. If you like to play large 3D games, it is necessary to pick a gaming notebook with 144Hz refresh rate screen and GTX1660Ti or higher discrete graphics card.
Screen Material
The LCD screen can be divided into LCD and OLED by material, of which, the LCD screen contains TN panels and IPS panels, the former is the lowest cost, there is a low viewing angle (mainly vertical), the angle of a large screen will appear off-color and white phenomenon. Most of the notebook screens are equipped with IPS panels.
TN Screen
IPS screen
The advantage of OLED material screen is rich color, higher contrast ratio, almost no power consumption when displaying pure black screen, combined with black desktop and dark background is conducive to prolong the battery life of the notebook. However, the cost of OLED screen is very high, only a very few products in the field of notebooks more than 10,000 yuan to have hunting installed, belongs to the top notebook patents.
Color gamut
The color gamut affects the color reproduction of the screen, the higher the color gamut means that the screen color display is more accurate and more comfortable to look at. Currently, the color gamut of notebook screens is generally 45% NTSC, 72% NTSC and 100% sRGB. Both 72% NTSC and 100% sRGB are “high color gamut” and have the same theoretical effect, except that 100% sRGB is more suitable for people who are engaged in professional image design.
High color gamut screen is the immediate needs of users engaged in design work
Matte Screen
Early notebook screens existed “matte” and “mirror”, both types of screen panels are directly “bare”, only “mirror screen “In the screen panel surface to add a layer of coating, forming a mirror-like effect, looks very high-grade. However, this mirror effect has serious reflective problems, either daylight or light will affect the normal viewing of the screen, so the new notebooks listed in recent years are almost all “matte screen”.
Glass Cover
In addition to supporting the touch operation of the notebook, there are now many thin and light notebooks are covered with a glass cover on the surface of the screen panel, which can play a role in protecting the screen, but also make the machine look more high-end. However, the protective glass will increase the weight of the machine, and bring a certain reflection problem, belong to the old “mirror screen” advanced version.
Anti-glare coating
Even “matte screens” have a degree of reflectivity. Therefore, many notebooks now have an anti-glare coating on the surface of the screen panel (or protective glass) to further reduce the refraction of light and maximize the sensory experience of using the notebook outdoors (under lights).
Screen replacement
The vast majority of laptop screens are removable, and if you are not satisfied with the screen color or resolution, you can purchase your own screen panel on Taobao and then replace and upgrade it yourself.
Most of today’s new laptop screen panels use the eDP interface, only the interface exists single-channel and dual-channel respectively, the latter has 30Pins of pins to support higher resolution signals. If you have the need to upgrade the screen later, be sure to confirm in advance whether the laptop and (newly bought) screen panel is compatible with each other.
