In the field of laptop screens, IPS and LCD are two common terms. But many users are not clear about the specific differences between them. In fact, IPS is not a completely opposite concept to LCD. IPS is a type of LCD technology, fully known as In Plane Switching technology. And the ordinary LCD screen we often refer to usually uses TN (Twisted Nematic) technology.
From a visual perspective, IPS screens have significant advantages. The viewing angle of a regular LCD (TN screen) is relatively narrow, usually around 170 °. When viewing the screen from the side, the image is prone to color deviation and reduced contrast. The viewing angle of IPS screens can reach 178 °, allowing for stable color and contrast at almost any angle. This is particularly important for users who need to share screen content with multiple people or frequently use laptops from different angles.
In terms of color performance, IPS screens are also leading. Ordinary LCD (TN screen) often only covers 45% -72% of the NTSC color gamut, and the colors are relatively dim. IPS screens can easily cover over 72% of the NTSC color gamut, and some high-end IPS screens can even reach 100% Adobe RGB color gamut, with bright and rich colors that can present more realistic image and video effects. For users engaged in design, film and television editing and other jobs with high color requirements, IPS screens are a better choice.
In terms of response time, traditional ordinary LCD (TN screen) has certain advantages, generally able to achieve 1ms, which makes it less prone to ghosting when processing high-speed dynamic images, and has wide applications in the field of esports games. However, with the development of technology, the response time of IPS screens is constantly shortening. Currently, some high-end IPS gaming screens can also reach 3-5ms, gradually narrowing the gap with TN screens in this regard.
