Definition of LED display viewing angle
Viewing angle refers to the angle at which the user can clearly observe all the contents on the screen from different directions. Viewing angle can also be understood as the maximum or minimum angle that can see the screen image. And the viewing angle is a reference value, full-color LED display viewing angle includes horizontal and vertical two indicators.
A horizontal viewing angle indicates that the vertical normal of the full-color LED display (i.e., the vertical imaginary line in the middle of the LED display) prevails, in the position of a certain angle perpendicular to the left or right of the normal can still see the display image normally, this angle range is the LED display horizontal viewing angle; the same if the horizontal normal prevails, the upper and lower viewing angle is called the vertical viewing angle. Generally speaking, the viewing angle is to contrast change as a reference standard. When the observation angle increases, the position to see the contrast of the display image will decline, and when the angle increases to a certain extent, the contrast ratio drops to 10:1, this angle is the maximum view angle of the LED display.

LED display viewing angle influences factors
Full-color LED display can be seen by the audience the greater the range, so the larger the viewing angle the better. But the size of the viewing angle is mainly determined by the tube core packaging method, so it must be carefully considered when packaging the tube core.
LED display viewing angle and viewing angle and distance have a lot to do with it, but at present most LED display manufacturers are unified if according to the site to give you a custom angle, the cost will be very high. It should be noted that the same chip, the larger the viewing angle, the lower the brightness of the LED display.
