Today, let us know what is the viewing angle of the full-color led display?
First, the full color LED display screen angle definition
The full-color led display 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 ability to see the maximum or minimum angle of the screen. And the viewing angle is a reference value, and the LED full color display viewing angle includes two indicators of horizontal and vertical.
For example, the full-color led display usually has the following description in the technical parameters (visual angle: 140°/140°); the maximum viewing angle is 140°, and the horizontal and vertical maximum viewing angles are 140°, over 140 degrees. After that, the viewing is not good or there is a blind spot.
The horizontal viewing angle indicates that the vertical normal line of the full-color LED display (ie, the vertical imaginary line in the middle of the LED display) is normal, and can still be seen normally at a position perpendicular to the left or right of the normal. Display image, this angle range is the horizontal viewing angle of the LED full color display; also if the horizontal normal is taken, the upper and lower viewing angle is called the vertical viewing angle. In general, the viewing angle is based on contrast changes. When the viewing angle is increased, the contrast of the displayed image seen at the position will decrease, and when the angle is increased to a certain extent, the contrast is reduced to 10:1, which is the maximum viewing angle of the full-color LED display.
Second, the full-color LED display screen viewing angle factors
The larger the full-color LED large screen can be seen by the audience, the better the viewing angle is. However, the size of the viewing angle is mainly determined by the way the die is packaged, so it must be carefully considered when packaging the die.
In addition, the viewing angle has a great relationship with the viewing angle and distance. However, most LED display manufacturers are unified at present. If you customize the angle according to the situation on the spot, the cost will be high. In addition, the same chip, the greater the angle, the lower the brightness of the LED full color screen.
