1. Definition of viewing angle of LED display: The viewing angle refers to the angle at which the user can clearly observe all the content on the screen from different directions. The viewing angle can also be understood as the maximum or minimum angle at which the screen can be seen clearly. And the viewing angle is a reference value, and the viewing angle of the full-color LED display includes two indicators, horizontal and vertical.

The horizontal viewing angle means that the vertical normal of the full-color LED display (that is, the vertical imaginary line in the middle of the LED display) shall prevail, and it can still be seen normally at a certain angle to the left or right of the normal. To display an image, this angle range is the horizontal viewing angle of the LED display; also, if the horizontal normal is the criterion, the upper and lower viewing angles are called vertical viewing angles. Generally speaking, the viewing angle is based on the contrast change as a reference standard. When the observation angle is increased, the contrast of the displayed image seen at this position will decrease, and when the angle is increased to a certain extent and the contrast is reduced to 10:1, this angle is the maximum viewing angle of the LED display.

2. Factors affecting the viewing angle of the LED display: the larger the range that the full-color LED display can be seen by the audience, the better, so the larger the viewing angle, the better. However, the size of the viewing angle is mainly determined by the die packaging method, so it must be carefully considered when packaging the die.

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