Explanation:
Visual angle refers to the angle from which the user can clearly see everything on the screen from different directions.
The light source that provides picture to liquid crystal display passes refraction and reflection after output has certain directionality, look beyond this limits can produce colour distortion phenomenon, and traditional CRT TV will not have this problem.
The visual Angle of LCD includes vertical and horizontal viewing Angle two indicators visual Angle, horizontal vertical normal viewing Angle said to display (displays in the middle of vertical imaginary line). In the perpendicular to the normal to the left or the right to the normal Angle position could see images, this Angle range is the level of the liquid crystal display visual Angle; Similarly, if the horizontal normal is used, the visual angles above and below are called vertical visual angles.
