What is tn in the liquid crystal display

TN is known as the Twisted nematic (twisted nematic) panel, low production cost makes TN the most widely used entry-level LCD panel, and is widely used in the mainstream low-end liquid crystal displays currently on the market. At present, we see more than the TN panel is modified tn+film,film that is compensated membrane, used to make up the TN panel visual angle, the current improved TN panel visual angle of 160 °, of course, this is the manufacturer in the case of contrast 10:1 of the measurement of the limit value, In fact, the image has been distorted or even skewed when the contrast drops to 100:1.

As a 6Bit panel, the TN panel can only display red/green/blue each 64 colors, the maximum actual color only 262.144, through the "jitter" technology can make it more than 16 million colors of performance, can only display 0 to 252 gray-scale three primary colors, So the final color display number of information is 16.2 m color, rather than what we usually call True color 16.7M color, plus the TN panel to improve the contrast degree of difficulty, the direct exposure of the problem is color thin, poor ability to restore, the transition is not natural.

The advantage of the TN panel is that the output grey class number is small, the liquid crystal molecule deflection speed is quick, the response time is easy to improve, the current market 8ms below the liquid crystal product basically uses the TN panel. In addition, Samsung has developed a B-TN (BEST-TN) panel, which is actually a modified TN panel, mainly to balance the TN panel high-speed response must sacrifice the quality of the contradictions. At the same time the contrast is up to 700:1 and can be close to MVA or early PVA panels. Taiwan many panel manufacturers to produce TN Panel, TN panel is a soft screen, with the hand lightly strokes will appear similar to the watermark.
