Most of the TN panels are modified TN+film, which is the compensation film, which is used to make up for the lack of viewing angle of the TN panel. The viewing angle of the improved TN panel is 160°. Of course, this is the manufacturer’s contrast ratio of 10:1. In the case of the measured limit value, the image has actually been distorted or even color cast when the contrast drops to 100:1.
As a 6Bit panel, the early TN panel with 6bit driver IC can only display 64 colors of red/green/blue, and the maximum actual color is only 262.144. Through the "dithering" technology, it can obtain more than 16 million colors. , Can only display the three primary colors of 0 to 252 gray scales, so the final color display information is 16.2 M colors, instead of the true color 16.7 M colors we usually call; it is more difficult to increase the contrast with the TN panel.
The exposed problems are thin colors, poor restoration ability, and unnatural transitions. In the later stage, with 8bit, this problem was solved to a large extent, and it was able to display the three primary colors of 0 to 255 gray scales, a total of 256 gray scales. In fact, the key factor that determines the color is not the panel type, but the driver IC. In the past, 99% of TN panels provided 16.2M colors, so people naturally think that TN and 16.2M have an inevitable connection.
