​The reasons why customers in the industrial and medical sectors are more likely to choose TN LCD?

In the current market where IPS, LTPS, OLED, AMOLED and other technologies are becoming more and more common, why could the TN panel still be widely used? They don't have a good viewing angle, 65° or even lower, but they have better industrial properties, such as a wider operating temperature range and a longer supply lifecycle. Many products using IPS, LTPS, OLED panels are more in line with the application of consumer products, and most of them are not suitable for the use of industrial control products. Why are these panels not suitable for industrial and medical products? The biggest headache is that their life cycle is short, basically only one to two years, which is fatal for industrial products. Industrial control products usually require a supply cycle of 5 to 10 years, and the discontinuation of LCD panels means the interruption of the supply of products and the failure of the project. Therefore, the TN LCD panel still has a place in industrial field.

However, TN LCD panels also have a disadvantage, the grayscale inversion phenomenon is very obvious. So what is a grayscale reversal? The display screen from 0 gray scale (black) to 255 gray scale (white) should theoretically be the higher the gray scale, the brighter it is, but when the display is at a large angle, it is possible to see that the low gray scale is brighter than the high gray scale, this phenomenon is called gray scale inversion. Therefore, the viewing angle of the TN panel is often 6 o'clock or 12 o'clock, and the display angle has certain limitations.

So how can we improve this disadvantage of TN LCD panels? Victronix Display Co., Limited can solve the problem for you perfectly, our O-Film TFT module can increase the width of the viewing angle and improve the grayscale inversion phenomenon. The following is a comparison of the general TFT and the O Film TFT, the normal TFT module on the left has begun to show the grayscale inversion problem when viewed from the 6 o'clock direction past the best viewing angle, but the grayscale inversion problem has been improved when the O-Film TFT on the right is also from the 6 o'clock direction beyond the best viewing angle.

Therefore, in the absence of full-view product substitution, O-Film TFT module is the best solution for wide viewing angle requirement.
