TN panels remain a very popular LCD option because of their advantages that revolve around inexpensive manufacturing and simpler production that translate further to cheaper price points for end consumers. Twisted nematic LCD technology was a breakthrough innovation that paved the way for an array of relatively inexpensive electronic devices that use digital electronic display. Conclusion: Advantages and Disadvantages of TN LCD panel This becomes more pronounced in cheaper and low-end panels. Note than another disadvantage of TN LCD panels is susceptibility to dead pixels. Images in low-end TN LCD panels can also be indiscernible when viewed under direct sunlight. The TN LCD panels used in these products can exhibit extreme color shifts even at slight change in viewing angle. Take note of cheap feature mobile phones as an example.
Low-end TN LCD panels have the tendency to exhibit extreme instances of other disadvantages such as poor viewing angle and poor color reproduction. Note that the quality of TN LCD panels depends on manufacturers. This is the reason why TN panels are not suitable for use in color critical tasks such as graphic design, photo manipulation, and video editing, among others. Poor color reproduction also means that color inaccuracy is another disadvantage of TN panels. Poor Color ReproductionĪmong the different types of LCD to include VA panels and IPS panels, TN panels suffer from poor color reproduction.Īpart from the inherent dull color reproduction in twisted nematic LCD technology, especially when compared against vertical alignment or in-plane switching LCD technologies, the problem with the limited viewing angle also produces poor representation of colors. Doing so can be problematic in larger TN LCD panels in which changing viewing angle is sometimes unavoidable. Nonetheless, the restricted viewing angle compels a user to remain sitting dead straight up in front of a TN LCD panel. User familiar with different types of LCD can easily discern if a panel is a TN panel through these color shifts and image distortion. When viewed from other angles, colors will appear duller and images will appear darker on a TN panel. A user needs to look at a TN panel from a straight up 90-degree angle to maximize its visual performance. Poor Viewing AngleĪ notable disadvantage of TN LCD panels is a narrow viewing angle.
Take note of the following limitations and disadvantages of TN LCD panels: 1. The disadvantages of twisted nematic LCD technology have prevented it from catapulting into more modern and wider applications however. The Drawbacks: Disadvantages of TN LCD panel In fact, some hardcore gamers prefer a TN computer monitor to a VA or IPS monitor due to its responsiveness and better refresh rate. These make TN LCD panels suitable for use in high-end gaming.
The better pixel response time and refresh rate advantages of TN LCD panels can enable them to display twice as much information every second. Furthermore, high-end TN LCD panels even have double the usual refresh rate of 120Hz instead of 60Hz. Pixels in a typical TN LCD panel change their state as fast as two milliseconds compared against the five milliseconds response time of a typical IPS LCD panel. Compared against IPS LCD panels, TN LCD panels have shorter response time and higher refresh rate.
