Factors Affecting The Viewing Angle Of Full Color LED Display 2017-09-06 09:44:06

Now we all know that whether it's a TV,a computer screen,or a LCD screen,they all have their viewing angles.Similarly,there is also a viewing angle in the LED display field.What is the viewing angle of full color LED display?What is the viewing angle associated with?

First,it’s the definition of the viewing angle of full color LED display screen.

Viewing angle is the angle that users can clearly observe everything on the screen from different angles.The viewing angle can also be understood as the ability to see the screen clearly at the maximum angle or the minimum angle.The viewing angle is only a reference,and the viewing angle of LED full color display includes both horizontal indicator and vertical indicator.For example,LCF’s rental LED display,the technical parameters are described in this way(visual angle:140 degrees/140 degrees).It means that the largest viewing angle is 140°,both the vertical and horizontal visual angle are 140°,when it's over 140 degrees,it may lead to undesirable watching-effect and blind spots.

Full Color LED Display

The horizontal viewing angle is based on the normal line of the full-color LED display(that is,the vertical imaginary line in the center of the LED display).when the display image is still visible at the angle of the left side of the normal line or the right side of the normal line,then the angle range is the viewing angle of the LED full color display.Similarly,if the horizontal normal is as the standard,the visual angle of the upper and lower angles is called vertical viewing angle.In general,the viewing angle is based on the contrast change as a reference standard.When the viewing angle increases,the contrast of the displayed image seen at this location will decrease,and when the angle increases to a certain degree,the contrast down to 10:1,this is the full color LED display’s maximum viewing angle.

Indoor Fixed LED Display

Second,there are factors affecting the viewing angle of full color LED display.

Generally speaking,the larger the full color LED screen can be seen by the audience,the larger the viewing angle is.But the size of the viewing angle is mainly determined by the tube packing method,so it must be considered carefully when packaging the tube.In addition,the visual angle is closely related to the visual angle and distance.But now most LED display manufacturers are unified in angle.The cost will be high if you have to customize the angle according to the circumstances.To the same chip,the greater the angle,the lower the full color LED’s brightness.
