What is the effect of the viewing angle of the full-color LED display


What is the effect of the viewing angle of the full-color LED display? The viewing angle of the full-color LED display refers to whether the video or picture displayed on the full-color LED display can be seen clearly when viewing the LED display on the left and right sides or up and down. The content, especially the stage LED display screen has many audiences, and the front audience can see clearly, but the audience on both sides may not see clearly, so when purchasing a full-color LED display screen, it is necessary to convey the requirements according to the purpose of the LED display screen Tailor-made for LED display manufacturers. The LHHY-P3 full-color LED display screen of United Huiye Technology can reach 160°/120° horizontal and vertical viewing angles, which can meet various display environments. Influencing factors of viewing angle of full-color LED display The larger the range of full-color LED display that can be seen by users, the wider the audience, but the viewing angle is mainly determined by the die packaging method, and the viewing angle The bigger the better, such as the outdoor LED display, due to direct sunlight during the day, the outdoor LED advertising screen must have enough brightness to be greater than the illuminance of the sun. If the angle is too large and does not concentrate, the brightness will be affected. When purchasing an LED display, you must take into account the main factors of concern. As the saying goes, you can't have the best of both worlds, you can only choose one.

In addition, the viewing angle has a lot to do with the viewing angle and distance, but at present, most full-color LED display manufacturers have uniform angles. If you customize the angle according to the situation on site, the cost will be very high. In addition, for the same chip, the larger the angle, the lower the brightness of the full-color LED display. Definition of viewing angle of full-color LED display The viewing angle refers to the angle at which users can clearly observe all content on the LED display screen from different directions. The viewing angle can also be understood as the maximum or minimum angle at which the screen can be seen clearly.

And the viewing angle is a reference value. The viewing angle of the full-color LED display includes two indicators: horizontal and vertical. The horizontal viewing angle means that the vertical normal of the full-color LED display (that is, the vertical imaginary line in the middle of the full-color LED display) shall prevail, and it can still be normal at a position perpendicular to the normal to the left or right of a certain angle. To see the displayed image, this angle range is the horizontal viewing angle of the full-color LED display; similarly, if the horizontal normal is taken as the standard, the upper and lower viewing angles are called the vertical viewing angle. Generally speaking, the viewing angle is based on the contrast change as the reference standard.

When the viewing angle is increased, the contrast of the displayed image seen at this position will decrease, and when the angle is increased to a certain extent, the contrast ratio will decrease to 10:1, this angle is the maximum viewing angle of the full-color LED display. .
