Teach you to estimate the visual range of LED display

The visual range of the LED display firstly depends on the horizontal viewing angle and vertical viewing angle of the screen itself, and secondly depends on the position of the audience and the visual discrimination ability of the human eye.

First of all, analyze from the horizontal viewing angle, the horizontal viewing angle of the screen is 160 degrees. It can be seen from the angle analysis diagram that when the seat is placed at a position greater than 0.64 meters from the screen, the left and right ends of the LED display can be seen. Next, analyze the seat position from the resolution ability of human eyes.

If the audience sits at a position of 3.97 meters, the vertical viewing angle is 46 degrees, and the lower angle is 0 degrees, which exceeds the dynamic sensitive area to meet the basic viewing needs, but to clearly see the top of the screen, you need to look up.

From the analysis of the standard field of view, if the intersection angle between the audience and the screen in the standard 50 meets the required mm lens range, then the seat is 5.18 meters away from the screen, which is the most ideal viewing distance. If the vertical angle falls in the dynamic visual sensitive area at the same time, it is within the range of 30 degrees viewing angle. The seat is 7.02 meters away from the screen, and the horizontal field of view is 55 degrees.
