Chapter 2 view distance and view angle.
In this video, we’ll introduce you to the view distance and view angle of LED displays. How to choose an LED display according to the viewing distance and viewing angle this is the Channel for people who want to learn basic knowledge of LED display in the last Video we learned the pixel pitch is the center distance of two pixels, and today I am going to introduce view distance and viewing angle. What is the viewing distance of the LED screen? Briefly, It is the distance between the viewer and the LED display.
What is OVD(optimum viewing distance)?
OVD in m =2* commercial pixel pitch in mm. For example P2.5, the pixel pitch is 2.5mm and OVD is 2*2.5=5 meters. When you choose a LED display, you need to know where your spectators are most likely positioned in relation to the LED display then you can calculate its pixel pitch according to the OVD formula. Let’s say that if the spectators are most likely in 10meters away from the LED display, then you can choose a P5mm LED display.
What is the minimum viewing distance?
It is 1/2 of OVD and also the 1000 multiples of the pixel pitch. For example P2.5mm, the minimum viewing distance is 2.5m.
This means you should stay further than the minimum viewing distance, so then you can get a better visual experience. Viewing angle It is the angle at which a LED display can be viewed with an acceptable visual experience.
What does an acceptable viewing angle mean?
We define an acceptable viewing angle as the angle range at which the luminance of the screen is exactly half of its maximum luminance.
Nowadays, there are more and more curable screens that require a wider viewing angle to give the audience a better visual experience in different viewing angles. so a wider viewing angle becomes a vital specification of LED screens.
