Except for this touch tft lcd display with TN glass, we also have various models which is with IPS glass. Do you know what's the difference between IPS and TN display?
1. Different viewing angles
Due to the manufacturing principle of the TN display, the viewing angle cannot be rotated too much when viewing, otherwise the content on the screen will not be seen. The film compensation film technology can be used to increase the viewing angle to 170°.
The ips display does not have these restrictions, and the content on the screen can be perfectly seen at an angle of 178°
2. Different color gamut
The TN display is a 6Bit native panel, which can only display 64 colors of red, green, and blue. The maximum actual color is only 262,144. It can be increased to more than 16 million colors through the "dithering" technology, but the final color display number is obtained. The highest is only 16.2 million colors.
The ips screen can display more colors, and its color accuracy is better than the TN display.
3. Different response speed
The grayscale response time of the TN display is longer, which will cause the dynamic image displayed on the screen to leave an afterimage, which will have a certain impact on the user.
IPS hard screen technology changes the arrangement of liquid crystal molecules, and adopts horizontal conversion technology to make the liquid crystal screen respond faster and more stable, and can perform excellent dynamic high-definition pictures. Compared with tn screens, it is more suitable for moving image reproduction. No afterimages and smearing.
