Brief Description:
1. Visual angle refers to the angle at which the user can clearly observe all the content on the screen from different directions.
2. The light source that provides the picture to the liquid crystal display has a certain directivity when it is refracted and reflected, which will produce color distortion phenomenon when viewed beyond this range, but the traditional CRT TV will not have this problem.
3. The visual angle of liquid crystal display includes two indexes: horizontal visual angle and vertical visual angle. The horizontal visual angle is represented by the vertical normal of the display (that is, the vertical imaginary line in the middle of the display), and the display image can still be seen normally at a certain angle perpendicular to the left or right of the normal.
4. This angle range is the horizontal visual angle of the liquid crystal display. Similarly, if the horizontal normal prevail, the visual angle up and down is called the vertical visual angle.
