1. Definition of the viewing angle of a full-color LED display
The viewing angle refers to the angle at which 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 at which the screen image can be clearly seen. And the viewing angle is a reference value. The viewing angle of a full-color LED display includes two indicators: horizontal and vertical.
2. Horizontal viewing angle and vertical viewing angle
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) is used as the standard. At a certain angle to the left or right of the normal, the display image can still be seen normally. This angle range is the horizontal viewing angle of the full-color LED display; similarly, if the horizontal normal is used as the standard, 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 increases, the contrast of the displayed image seen at this position will decrease. When the angle increases to a certain extent and the contrast drops to 10:1, this angle is the maximum viewing angle of the full-color LED display.
