The panel type is related to the important factors such as the response time, color, viewing angle, and contrast of the liquid crystal display. Commonly used LCD panels include TN (Twisted Nematic), IPS (In-Plane-Switching), and VA (Vertical Alignment). The first two are relatively common.
1. TN screen: fast response time is an advantage
2. IPS screen: wide viewing angle, good color
3. VA screen: high contrast
