Theoretically, the maximum LCD view angle is 90° and might vary for each measuring direction. The three-dimensional angular range is called a viewing cone.
Why is a viewing angle important?
Viewing angles has a huge impact on the kind of image you are going to view on your screen. The quality of the image that you are seeing on the screen depends on the distance you are standing at, the direction you are viewing it from and the angle you are viewing it from.
The viewing angles of screens are measured both vertically and horizontally to find out at what range of angles a display can be viewed without seeing a negative image.
If you view the image from an angle wider than the viewing angle of the display, you’ll not be able to experience the best visuals.
LCD displays are supposed to be viewed by the audience and provide the audience with a good viewing experience.
If the image displayed on the screen cannot be viewed by the audience properly, then there’s no point in wall mounting LCD display. For this reason, it is important to ensure that the LCD display has an appropriate viewing angle needed for the usage and location of the wall mounting LCD display.
