What Are The Factors Affecting The Viewing Angle Of LED Display? LED WORLD Tell You
1. The definition of LED display viewing angle:
visual Angle refers to the Angle from which users can clearly observe all contents on the screen from different directions.Viewing Angle can also be understood as the maximum or minimum Angle from which the screen can be seen.And the viewing Angle is a reference value. The viewing Angle of the full-color LED display screen includes two indicators, horizontal and vertical.
The explaination of LED Display viewing angle:
Horizontal viewing Angle refers to the vertical normal line of full-color LED display screen (i.e., the imaginary vertical line in the middle of LED display screen). The display image can still be normally seen at a position perpendicular to the left or right of the normal line.Similarly, if the horizontal normal line is used, the Angle of view above and below is called the vertical Angle of view.Generally speaking, the visual Angle is based on the contrast change.When the viewing Angle is increased, the contrast of the display image seen in this position will decrease, and when the Angle is increased to a certain extent, the contrast drops to 10:1, this Angle will be the maximum viewable Angle of the LED display.
2. Factors affecting the viewing Angle of LED display:
the larger the range of full-color LED display that can be seen by the audience, the better, so the larger the viewing Angle is.But the size of the visual Angle is mainly determined by the tube core packaging, so in the packaging of the tube core must be carefully considered
The viewing Angle of LED electronic screen has a lot to do with the viewing Angle and distance. However, most full-color LED display manufacturers are unified at present. If you customize the Angle according to the situation of the scene, the cost will be very high.Note 1: for the same chip, the higher the viewing Angle, the lower the brightness of LED display.
