The two commonly used screens in the POS industry are TN screens and IPS screens. The TN screen is more suitable than the main screen of the POS terminal due to its smaller viewing angle, which can ensure the privacy of the operation. Compared with the TN screen, the IPS (In-Plane Switching) screen has more advantages in color, viewing angle, and display clarity, and is an ideal choice for the second display of the POS terminal.
1. The IPS screen’s viewing angle reaches up to 178 degrees, meaning customers can view the display clearly from any angle, with accurate and consistent colors. In contrast, the TN screen has a more limited viewing angle and tends to show weaker color reproduction.
2. The second display of the POS terminal can be used to play promotional advertisements. The color reproduction effect of the IPS screen is better than that of the TN screen, and it can display more realistic and vivid images and videos.
3. Some POS terminals include a touch function on the second display, enabling customers to interact by performing tasks such as checking in, querying points, and providing feedback. IPS screens support multi-touch, smooth operation, and are not prone to lag.
5. IPS screens are designed with a special liquid crystal molecule arrangement, making them more durable and less likely to experience colour shifts or brightness reduction over time.
