We absorb information from display at every moment. Are you aware of the difference when you watch your display at each angle? The main reason is transmission of light rays of different elevation angle on the surface. There is quite different between watching from front view and side view. It has the scope of view angle.

Technology

TN technology has been widely used in the industrial equipment. The disadvantages of TN-LCD type are narrow viewing angles and gray scale inversion. Gray bars are from gray level G0 (black) to G255 (white). Theoretically, the higher gray level is, the higher brightness is. However, you can see low gray level is brighter than high gray level at some specific angles and that is called gray scale inversion.
