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.
