What Are The Factors Influencing The Viewing Angle Of Full-color LED Display?

1、 Definition of viewing angle of LED display

Visual angle refers to the angle that users can clearly observe all the contents on the screen from different directions. The viewing angle can also be understood as the maximum or minimum angle to be able to see the screen. And the visual angle is a reference value. The visual angle of full-color LED display includes horizontal and vertical indicators.

The horizontal viewing angle refers to the vertical normal of the full-color LED display screen (that is, the vertical imaginary line in the middle of the LED display screen). The display image can still be seen normally at a certain angle perpendicular to the left or right of the normal. This angle range is the horizontal viewing angle of the LED display screen. Similarly, if the horizontal normal is taken as the standard, the upper and lower viewing angles are called vertical viewing angles Angle. Generally speaking, the visual angle is based on the contrast change as the reference standard. When the viewing angle increases, the contrast of the display image will decrease. When the viewing angle increases to a certain extent and the contrast drops to 10 ∶ 1, this angle is the maximum viewing angle of the LED display.

2、 Influencing factors of viewing angle of LED display

Full color LED display can be seen by the audience the larger the better, so the larger the viewing angle, the better. But the size of the visual angle is mainly determined by the chips packaging method, so it must be carefully considered when packaging the chips.

The viewing angle of LED display has a great relationship with viewing angle and distance, but at present most of the LED display manufacturers are unified. If you customize the angle according to the situation on site, the cost will be very high. It should be noted that the larger the viewing angle of the same chip, the lower the brightness of the LED display.
