Viewing direction is a parameter used mainly in TN (Twisted Nematic) LCDs. It defines the direction from which the display offers optimal readability, accurate colors and proper contrast. Choosing the right viewing direction helps prevent TN-specific issues such as grayscale inversion, contrast loss or dimming. It is especially important in devices where the user’s position relative to the screen is fixed, such as machine control panels, counters or medical instruments.
