We know that TV, computer monitors and LCD screens have a viewing angle. Also in the display field, LED displays have this statement. What is the viewing angle of the LED display? What is the factor? The following is introduced to everyone.
First, the LED display angle definition: the viewing angle, the user can clearly observe the angle of all content on the screen from different directions. The angle of view can also be understood as the maximum or minimum angle at which the screen can be seen. And the viewing angle is a reference value, and the full-color LED display viewing angle includes two indicators of horizontal and vertical.
The horizontal viewing angle indicates the vertical normal of the full-color led display (ie, the vertical dashed line in the middle of the LED display), and the normal display image can still be seen normally in the position perpendicular to the left or right. The angle range is the LED display. Horizontal viewing angle; in addition, if horizontal normal is used, the upper and lower viewing angles are referred to as vertical viewing angles.
Typically, the angle of view is based on contrast changes. As the viewing angle increases, the contrast of the displayed image seen at that location will decrease, and as the angle increases to a certain extent, the contrast is reduced to 10:1, which is the maximum viewing angle of the LED display.
Second, the LED display angle influence factor: the full-color LED display allows the viewer to see as much as possible, so the larger the angle, the better. However, the size of the viewing angle depends mainly on the way the chip is packaged, so it must be carefully considered when packaging the chip. The viewing angle of an LED display has a lot to do with the viewing angle and line of sight. However, most LED display manufacturers are currently unified. If you customize the angle based on site conditions, the cost will be high. It should be noted that the same chip, the larger the viewing angle, the lower the brightness of the LED display.
