Led display basic knowledge - Chapter 2 view distance and view angle idisplayled

Chapter 2 view distance and view angle;


In this video, we'll introduce you about view distance and view angle of led display.




How to choose 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 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 viewing distance of led screen? In Briefly, It is the distance between viewer and led display

what is optimum viewing distance/OVD. 

OVD in m =2* commercial pixel pitch in mm

for example

P2.5, pixel pitch is 2.5mm

and OVD is 2*2.5=5meter

When you choose a led display, you need to know where your spectators are most likely positioned in relation to led display

then you can calculate its pixel pitch according to OVD formular.


Let’s say that if the spectators are most likely in 10meters away from led display, then you can choose a p5mm led display.

What is minimum viewing distance?

It is 100times of pixel pitch, which is also 1/2 of OVD

Which means you should stay further than minimum viewing distance, then you can get a better visual experience

 


Viewing angle 

It is the angle at which a led display can be viewed with acceptable visual experience.

What does acceptable means? 

We define that acceptable viewing angle as the angle at which the luminance of image is exactly half of its maximum

The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen. 

Viewing angle formular is 2θ0.5


Θpeak is the angle between center axis to the optical axis at maximum brightness.


θ0.5 is the angle between peak axis to half luminance optical axis 

Nowadays, there are more and more curable screens which require a wider 


viewing angle to give audience a better visual experience in different viewing angle. 

so wider viewing angle is become a vital specification of led screen


Quality LED display PCB board and summary PCB knowledges

In this article we introduce quality LED display PCB board and summary PCB knowledges;

PCB is short for 'printed circuit board', up to 1936, Dr Paul Eisner really invented PCB manufacturing

technology and published a number of patents.

PCB including copper platinum, base materials, corvered copper plate.

There are lots kinds of base materials.

Common substrate types including:

XPC phenolic resin substrate, FR-1 phenolic resin substrate, FR-2 phenolic resin substrate, CEM-1 epoxy resin composite substrate,

FR-4 epoxy fiberglass board, other resins -BT, PI, PTFE fiber cloth/organic fiber, etc.

PCB can be classification by hardness, material, structure, to different types.

And we also introduce QC test of PCB in short in this video.

What is can mode of led display? 1/6 scan mode, means 1/6 LEDs on the module are driven by IC at one time, and next time there are other 1/6 LEDs that are driven. Note: Because of the scan mode change scan lines very fast, and can’t be distinguished by human eyes, so visually, we feel the LEDs are light on all the time, but in fact, the scan mode has LEDs off when we see it.What is led display? LED Display (light-emitting diode display) is a screen display technology that uses a panel of LEDs as the light source.What is your products? Outdoor and indoor poster, flexible screen, traffic sign, outdoor fixed screen, shopping shelf display etc.
