Naked Eye 3D LED Display characteristics analysis

1、Glasses-free 3D LED display screen strong stereoscopic feeling - out of the box visual effect

Glasses-free 3D LED display brings a strong stereoscopic feeling to the audience with its unique visual presentation. Compared to the traditional Indoor Led Display and Outdoor Led Display, why does Glasses-free 3D LED display provide a deeper stereoscopic feeling? Some people may think that this is because of the folded corners of the screen design, however, even in the absence of folded corners of the screen, we are still able to experience a significant 3D effect.

To answer this question, we first need to explore a key element of naked eye 3D display technology: out-of-frame. The out-of-frame effect means that the main part of the picture seems to "fly" out of the boundaries of the frame, a design that cleverly tricks our eyes and thus affects our brain's perception.

In our daily lives, we come into contact with display devices such as TVs, cell phones, and computers where the image is usually confined to a frame. The existence of such a border makes us form a consensus that the picture should appear inside the border. Designers utilize this psychological expectation to artificially add a visual effect of a border to the picture. In some cases, parts of the screen are even intentionally kept completely black to reinforce this border effect. In some cases, designers even cleverly "copy and paste" the windows of the next building into the screen to further enhance the realism of the border. When the main body of the picture exceeds the preset frame in our brain, the visual contrast will bring us a strong 3D sense. This out of the frame design approach, not only breaks through the traditional picture boundary limitations, but also visually brings us a new, immersive experience.

2、Direct-view 3D LED display screen unique performance - picture distortion phenomenon analysis

The current so-called naked eye 3D technology, in fact, is not the true meaning of naked eye 3D, this kind of display only in the audience at a particular angle, and play a special customized for the big screen when the particular video, in order to present a strong sense of three-dimensional. Once the viewing angle or video content does not meet these specific conditions, the screen will appear distorted phenomenon. Some attentive netizens may have noticed on the network of some "through the gang" video clips. To take a simple example, in a flat plane, a straight line should maintain its straight shape no matter what angle it is viewed from. However, this changes when the line is placed in a shaped screen. Only when the viewer's eyes are at an equal angle to the line will the line maintain its original straight form.

So what do we do with the animation inside the display when we need to look up at the big screen in the plaza to give the Direct-view 3D effect? This requires us to project this straight line onto the screen to achieve the effect of a straight line in the viewer's perspective. However, on the screen, the line will actually appear as a curved and angled arc. In this way, when the viewer views the line from a specific angle, he or she will be able to see the correct proportions and shape.

Therefore, the production of content for Glasses-free 3D LED display is a rather complex process. First of all, the production staff need to determine the audience's viewing angle, which includes standing, sitting and reaching out with a cell phone to shoot the height, etc., combined these values range to take a middle value. Then, according to the structure of the screen to carry out the spatial extension, build the scene, and ultimately render the video suitable for playback in the big screen. This process not only requires specialized technical knowledge, but also requires an in-depth understanding of the audience's viewing habits and visual perception.

3、Advanced naked-eye 3D LED display screen depth of charm - the creation of inner space

In the pursuit of naked eye 3D display effect, the creation of inner space has become an important technical means, which can create a sense of depth of the picture, thus creating a three-dimensional visual effect. In short, inner space is to build a sense of three-dimensional space with depth on a flat or curved surface through specific visual elements and design techniques.

As an example to illustrate this concept, we can imagine an originally dark plane, when a few lines are skillfully added to it, the plane will immediately present a sense of spatial depth. This simple but effective technique is a visualization of the creation of internal space.

Whether it is in the production of video content for large flat screens or curved screens, we can see this technique of creating internal space is widely used. Through the carefully designed layout of elements and light and shadow effects, the interior of the screen seems to be endowed with a three-dimensional spatial structure, enabling viewers to feel a strong sense of depth and three-dimensionality when watching. The use of this technique not only enhances the visual effect of the Glasses-free 3D LED display, but also gives the audience a more immersive viewing experience.
