What is a naked eye 3D LED display?
Without the need to wear 3D glasses, standing in front of the large screen, the picture can fly to the eyes, as if you were in the general experience. This is the visual experience brought by the naked eye 3D screen.
For example, the naked eye 3D effects such as the sudden wave of the sea in front of the SM company building in South Korea, the robot dog in the Jiefang Monument in Chongqing, and the spaceship in Taikoo Li on Chunxi Road in Chengdu have brought warm responses on the Internet and short video apps. Naked-eye 3D will become a form of display to create a new type of landmark media.
In fact, 3D naked eye technology is not mysterious, it is essentially the embodiment of visual deception. In order to achieve extremely three-dimensional naked-eye 3D video, two factors are essential.
1.3D naked eye LED display boundary sense.
Naked eye 3D video is done to a certain extent using human visual deception. Normally, the content of the video is usually inside the border. If we put the content of the video as a boundary, people will instinctively think that the picture on the screen is fake. Therefore, when we do video content for the LED display, we need to artificially add a border to it. For example, this spaceship, in fact, there is a large screen on the right side of the screen, but they are deliberately not lit up, creating a convenient effect. When the main picture is beyond the frame, it will bring cognitive contrast to people. To achieve a 3D stereo effect.
2. 3D naked eye LED display artificially distorted picture.
The naked-eye 3D display has the best stereoscopic effect only when viewed at a specific Angle and distance. If it is too close, or left to right, the picture is distorted. In general, the naked eye 3D screen is curved, and if we play normal video, the picture we see on the screen is distorted. But if it is displayed normally on the naked eye 3D screen, we can only observe it in a specific position.
Therefore, before making the naked-eye 3D display, we need to know the resolution and size of the large screen, the number of angles, the distance position, etc., to make specific materials that match the naked-eye 3D large screen. So, every 3D LED display is unique.
