WHAT ARE IMAGE VIEWING ANGLES?
In televisions and screens of all kinds, the viewing angle is the position from which the viewer can see an image or video adequately.
On screens with a reduced viewing angle, you can only get a clear image by positioning yourself in front of the screen.
LED SCREEN VIEWING ANGLES
The viewing angles of a LED screen are measured horizontally and vertically and indicate at which range the image on the screen is visible in regard to the perpendicular view of its surface. For example, in a 160/120 viewing angle, the first number (160) represents the horizontal viewing angle and indicates that an image on the screen is visible if we move up to 160 degrees horizontally (that its, from one side to the other). The second number (120) represents the vertical viewing angle and indicates that the image on the screen is visible up to a 120 degrees vertically. This vertical angle is very important for LED screens that are above ground levels, such as those hanging or located on poles, monopoles, facades.
WHY ARE VIEWING ANGLES IMPORTANT FOR A LED SCREEN?
The viewing angles of a screen affect the audience’s adequate perception of the content. Therefore, your screen should have a horizontal viewing angle between 120 and 160 degrees and a vertical angle between 120 and 160 degrees.
The type of LEDs used in a screen can have an impact on the viewing angles it offers. The SMD and vandal resistant LEDs favor better viewing angles
In addition, by incorporating the 3 basic light colors in the same capsule, there is no visual interference when viewing contents from wide angles. In the screens with DIP LEDs, these angles are reduced due to the LED’s structure. Since the three basic colors are in separate LEDs, a slight loss of visibility of one of the colors may happen when viewing contents from extreme angles. This means that a color may dominate the image perceived by the spectator, degrading the image’s fidelity.
