The laptop screen quality is easy to ignore. The following content helps you understand how to choose an LCD screen:
Resolution: The screen ratio and resolution of the laptop have evolved over the years, from WVGA (800 * 480) and WXGA (1280 * 800) at 16:10 to 1366 * 768 at 16: 9 which has occupied the mainstream market for nearly ten years, To today's mainstream Full HD FHD (1920 * 1080), and higher 3K \ 4K resolution, it has derived a variety of specifications. In recent years, many high-resolution screen products have appeared in the notebook, and 4K has become common..
Color gamut: Color gamut refers to the vividness of colors on the screen. Now laptop screen has two color gamut standards, NTSC and sRGB. Laptop screen color gamut can be divided into 45% NTSC and 72% NTSC and 100% SRGB. In terms of the products on the market at present, 72% NTSC and 100% sRGB are considered high-quality products.
Material: The display screen can be roughly divided into the LCD screen and OLED screen. At present, most of the laptops are equipped with LCD screens, and there are very few OLED products. TN and IPS are the most common LCD products.
TN is the twisted nematic panel. This kind of panel is widely used in the laptop because of its low cost. The advantages of TN panels are fast response speed and low cost, but poor color performance, unnatural transition, and very small viewing angle.
IPS is In-Plane Switching. It is an LCD panel technology introduced by Hitachi in 2001. IPS is a general name for this type of panel, which is also commonly known as a hard screen. There is no water ripple when the finger press on the panel and the color is accurate. The viewing angle is large, but the disadvantage is the light leakage problem. Compared to TN screens, IPS screens are also more suitable for touch devices.
Refresh rate: The refresh rate is the number of times the electron beam repeatedly scans the image on the screen. It is the number of screen refreshes per second of the display. The higher the refresh rate, the more images are refreshed per second. At present, most laptop screen refresh rates are 60Hz. Since 2008, many OEM manufacturers have launched gaming laptop with 144HZ screen.
