When reviewing a TFT LCD’s specifications, MVA, IPS, PVA and other acronyms indicate that the LCD offers a true wide viewing cone. In other words, images are as clear, colors are as good up to 89 degrees from the center as they are looking straight on at the LCD.
A TN or Twisted Nematic TFT LCD is a cost-effective high performance LCD. It offers good brightness performance and fast response times. However, it suffers in one key area and that is its viewing cone. TN LCD’s typically have three good viewing angle directions. In these directions the image is typically clear and colors are consistent up to 80 degrees from the center of the LCD. The remaining viewing direction is usually good through 40-50 degrees from center. Afterwards, the image is likely to invert, almost appearing like an x-ray.
Display Logic enhances the poor performing viewing angle; typically the top or bottom angle to perform equally as well as the remaining three angles.
