What is the TN panel?

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 early TN panel with 6bit Drive IC only shows 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. Late cooperation with 8bit to a large extent to solve this problem, and can display 0 to 255 gray-scale three primary colors, a total of 256 gray-scale, in fact, the key factor in determining color is not the panel type, but the driver IC. In the past 99% TN panels provide 16.2M color, so it is logical to think that TN and 16.2M have a certain connection.　　At the same time, 16.7M color is a wide view panel of the patent, so also give the user left such an impression--tn panel is equal to 16.2M color, wide view panel equals 16.7M color. The principle of the liquid crystal display color is that the position of each pixel on the back plate has three strips which are only filtered through the red and green blue light, each pixel in each stripe has a separate circuit driving the corresponding position of the liquid crystal molecule rotation, so that the different brightness of the red, green and blue three-color mixing, so that people's eyes feel a variety of colors. The voltage increases the angle to be big, the voltage adds the low angle to be small, is the stepless adjustment. The driving voltage from the highest to the lowest 2n can make the liquid crystal display n-bit color. As a result, people who have a slightly longer head know that there is no board that supports only a few bits of color.　The only number of driver colors displayed for any single LCD panel is the best problem. In other words, regardless of TN or wide view panel, if the load is 6bit IC, then its color number is 16.2M (after jitter processing), if loaded 8bit IC, then the color number is 16.7M.　　According to our previous summary, the panel type and color does not matter, then can be inferred that the wide view panel can also be paired with 6bit IC, providing 16.2M color. 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.
