What is a key disadvantage of Twisted Nematic panels?

High cost
High power use
Limited viewing angles
High refresh rates

The correct answer is: Limited viewing angles

Twisted Nematic (TN) panels have fast response times and are relatively cheap to produce, making them a popular choice for computer monitors. However, one of the key disadvantages of TN panels is their limited viewing angles. This means that the image on the screen may appear distorted or washed out if viewed from an angle, making them less suitable for tasks that require accurate color representation or for sharing the screen with others. Option A, high cost, is incorrect because TN panels are actually considered one of the cheaper options for display panels. Option B, high power use, is also incorrect because TN panels have low power consumption compared to other display panels. Option D, high refresh rates, is incorrect because TN panels tend to have faster refresh rates compared to other display panels.
