Many people ask what is the viewing angle of a full-color LED display? What are the determining factors? Generally speaking, the larger the range that the full-color LED display can be seen by users and friends, the better, so the larger the viewing angle, the better. Let's talk about LED display manufacturers in detail.
The viewing angle refers to the angle at which the user can clearly see all the content on the screen from different directions. The viewing angle can also be understood as the maximum or minimum angle at which we can see the screen 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 line of the display screen shall prevail, and the display image can still be seen normally at a certain angle to the left or right of the normal line. This angle range is the horizontal viewing angle of the LED display screen; Likewise, if the horizontal normal is used, 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 decreased to 10:1, this angle is the maximum viewing angle of the LED full-color screen.
For example, the technical parameters of the LED full-color advertising screen are marked as follows: the horizontal viewing angle is 120° and the vertical viewing angle is 120°; it means that the full-color LED display has a maximum horizontal viewing angle of 120° and a maximum vertical viewing angle of 120°. °
What factors are related to the viewing angle of the full-color LED display?
The size of the viewing angle is mainly determined by the die packaging method, so it must be carefully considered when packaging the die. In addition, the viewing angle has a lot to do with your viewing angle and distance, but at present most LED display manufacturers have the same angle.
