Using outdoor advertising LED display for promotion and brand promotion is not new. However, recently, some innovative ideas have once again made the display technology industry boiling, presenting amazing naked eye 3D visual effects on outdoor LED displays. The visual effect brought by 3D LED display is more powerful and aesthetic than any traditional LED static image, making it the next focus of display technology.

 


How does the 3dled display work?


Without the assistance of 3D glasses, how does this immersive naked eye 3D visual display come into being? 3D LED screen is actually a combination of 3D digital display technology and traditional flexible LED screen to generate 3D images. The reason why people can enjoy naked eye 3D images or videos is that the depth of images displayed on 3D LED displays is different, which makes the human eye perceive the displayed 2D images as 3D images.


We are born with a sense of 3D space. When our eyes see an object, because the distance between the two eyeballs is very small, two different tiny pictures will appear, which enables the brain to calculate the spatial coordinates between objects, thus showing a three-dimensional effect. The 3D display technology of glasses also adopts the same principle to separate the images and send them to the left and right eyes of the viewer respectively to achieve the 3D effect.


The 3D LED screen uses a flexible LED screen that can be bent into a certain radian or 90 degrees as the hardware to combine two images taken from different angles into one lens. When we view these images with the left and right eyes, parallax occurs, resulting in the depth observed in 3D technology.

 

 3D LED Display


3D LED display is not to create 3D effect with distinct structure, but to realize 3D effect on billboard display by using digital technology and naked eye imaging, which is the biggest difference between 3D LED display and 2D display. As consumers' expectations of 3D LED screen become higher and higher, and the advertising effect it brings to the brand, 3D LED screen is more and more favored by audiences and brands.


The naked eye 3D screens that have become popular in recent years are all composed of two pictures from different angles. The display screen folds the picture by 90 °. Using the video material that conforms to the perspective principle, the left screen shows the left view of the image, and the right shows the main view of the image. When people stand in front of the corner to view, they can see the side and front of the object at the same time, presenting a realistic three-dimensional effect.
