TN panel, the full name is Twisted Nematic (twisted to bai column type) panel. Due to the low production cost, TN has become the most widely used entry-level LCD panel.
The characteristic of the TN panel is the fast deflection speed of the liquid crystal molecules, so it is easy to improve the response time. But its color performance is worse. The TN panel is a soft screen, and a similar water pattern will appear when you lightly swipe it with your hand.
Due to the lack of viewing angle, this type of panel display is gradually withdrawing from the mainstream market.
