 Naked Eye 3D Outdoor Advertising LED Display Screen

Recently, the "L-shaped" screen that has exploded on the Internet has attracted many people to check in. Such LED display screens frequently appear in major cities, attracting everyone's attention with shocking and realistic picture effects. Most of the naked-eye 3D large screens in shopping malls are corner screens to present real and three-dimensional images to users. So do you know how this effect is produced? What are the application advantages of the naked eye 3D LED large screen? What black technology is hidden behind it?

01-Effect Production

To be able to achieve such a strong three-dimensional video, two key features must be used here.

1) Border

The picture above has such a strong sense of three-dimensionality even though there are no folded corners. By letting the main body of the picture come out of the frame, people will instinctively think that the picture on the screen is fake, and both TVs and computers will have borders, so The picture should be within the border, we need to artificially draw a border.

For example, in this spaceship, there is actually a large screen on the left side of the screen, but they are deliberately not lit up to create a border effect. The giant panda falls, the lion's cage, the electronic hand's room, etc. are all the same. And when the main picture exceeds the frame, it will bring people a cognitive contrast. Thereby realizing the stereo effect of 3D.

2) Man-made Distorted Images

Obviously, this large 3D screen can only have the best three-dimensional effect when viewed from a specific angle. This is what the picture will look like if viewed from too low an angle, or if you play a normal video.

Normal picture

Even at the best angle, if the picture is not artificially distorted, it will look like this. The original road was folded up. But if a straight line is displayed on a special-shaped screen, we can only observe it at the same height as the straight line. Viewed from other positions, this straight line is angled. This kind of naked-eye 3D video generally only has a three-dimensional effect when viewed from a specific angle. Viewed from other angles, the picture will be stretched and deformed to achieve the desired effect. We need to know the resolution and size of the large screen, where the corners are on the large screen, follow up the size of the large screen to build the corresponding field volume, choose the appropriate angle to render the scene, and match the rendered film or video with post-production software to the resolution size of the large screen.

Next, I will show you the effect of objects appearing on different screens.

Therefore, you need to choose the best viewing position first, and then there is no need to equalize the screen according to this position, and make a video according to this curvature. Of course, if we change to another location to observe the picture, the picture will definitely not be perfect.

02-Application Advantages

1) Three-dimensional stereoscopic effect

Utilizing the screen shape and frame effect, it creates the feeling of a three-dimensional scene, which can bring users a visually impactful experience, and can also be used as a brand-new advertising and marketing promotion method.

2) Full sense of technology

The naked-eye 3D LED large screen that combines culture and technology is not only a cool effect, but also outputs culture to users in a trendy way, creating a unique visual expression effect. The effect display of naked-eye 3D technology is a unique display of culture and art through the naked-eye 3D advertising screen, which improves the aesthetics of the public.

3) Accurate information transmission

The visual effect is one of the display features of the naked-eye 3D LED large screen, and the information transmission effect can be conveyed through the film created by the naked-eye 3D technology. The novel and unique picture display firmly grasps the user's vision. Therefore, the naked-eye 3D advertising screen has gradually become one of the ways of marketing and promotion. The display of the naked-eye 3D LED large screen can not only bring users a novel and unique visual experience, but also enliven the atmosphere of the scene through a series of display methods during the display process.
