The advantages of TN panels are that due to the small number of output gray levels, the rapid deflection of liquid crystal molecules, and the easy improvement of response time, TN panels are basically used in liquid crystal products below 8ms on the market.
In addition, Samsung has also developed a B-TN (Best-TN) panel, which is actually an improved type of TN panel, mainly in order to balance the contradiction of high-speed response of TN panel that must sacrifice image quality. At the same time, the contrast ratio can reach 700:1, which is close to MVA or early PVA panels.
Many panel manufacturers in Taiwan produce TN panels. TN panels are soft screens, and similar water lines will appear when you lightly swipe them with your hands.
