What is the viewing angle of the LED display?

Viewing angle refers to the angle at which users can clearly see all 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. The viewing angle of a full-color LED display includes two indicators, horizontal and vertical.

The horizontal viewing angle means that the vertical normal line of the display screen (that is, the vertical imaginary line in the middle of the display screen) shall prevail. The displayed image can still be seen normally at a certain angle to the left or right of the normal line. This The angle range is the horizontal viewing angle of the LED display; similarly, if the horizontal normal is taken as the standard, the vertical viewing angle is called the vertical viewing angle. Generally speaking, the viewing angle is based on the contrast change as a reference standard. When the viewing angle increases, the contrast of the displayed image at that position will decrease, and when the angle increases to a certain extent, the contrast decreases to 10:1, this angle is the maximum viewing angle of the LED full-color screen.

For example, the technical parameters of LED full-color advertising screens are marked as follows: the horizontal viewing angle is 120° and the vertical viewing angle is 120°; that is, the maximum horizontal viewing angle of the full-color LED display is 120°, and the maximum vertical viewing angle is 120. °

What are the factors 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. Liancheng sends LCF to remind you: If you customize the angle on site, the cost will be very high. . In addition, with the same chip, the greater the viewing angle, the lower the brightness of the LED display.
