What is the viewing angle of a full-color LED display?
We know that televisions, computer monitors, and liquid crystal displays all have a viewing angle. This is also true in the field of LED screens. What is the viewing angle of a full-color LED display? What is the viewing angle? With this question, learn together:
First, full-color LED display viewing angle definition
The viewing angle refers to the angle at which users can clearly observe all the contents of the screen from different directions. The viewing angle can also be understood as being able to see the maximum or minimum angle of the screen. And the viewing angle is a reference value. The full-color LED display viewing angle includes two indicators, horizontal and vertical.
For example, Waitem rent led display, the technical parameters inside have this description (visual angle: 140 ° / 140 °); said is the maximum viewing angle of 140 °, the maximum horizontal and vertical viewing angle is 140 °, more than 140 After viewing it, the viewing effect is poor or there is a blind spot.
The horizontal viewing angle means that the vertical normal of the full-color LED display screen (ie, the vertical imaginary line in the middle of the LED display screen) prevails, and normal viewing is still possible at a position perpendicular to the left or right of the normal line. Display image, this angle range is the full-color LED display horizontal viewing angle; also if the horizontal normal prevail, the upper and lower viewing angle is called vertical viewing angle. In general, the viewing angle is based on the change in contrast. When the viewing angle is increased, the contrast of the display image seen at this position will decrease, and when the angle is increased to a certain degree and the contrast ratio drops to 10:1, this angle is the maximum viewing angle of the full-color LED display screen.
Second, the full-color LED display viewing angle influencing factors
The larger the full-color LED screen can be seen by the audience, the better, so the larger the viewing angle, the better. However, 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 the viewing angle and distance, but at present most of the manufacturers of LED display screens are unified. If you customize the angle according to the situation on the spot, the cost will be high. In addition to the same chip, the higher the angle, the lower the brightness of the LED full-color screen.
