1.What is a 3D naked eye led screen?

3D naked eye led screen refers to the LED display large screen that the human eye can see the stereoscopic display effect without using visual AIDS such as polarized glasses. This is a new way of media presentation, using MINI distributed optical matrix 3D fusion screen superimposed professional 3D audiovisual materials, to present visual shock and impact with perfect display effect, naked eye 3Dled screen broke through the artistic boundary, subverting the traditional tablet video display mode.

2.3D naked eye led screen and conventional led screen difference?

(1) Beautiful structure :right-angle arc transition, coherent and complete display, providing a structural modeling basis for presenting realistic 3D naked eye led screen effect, perfect combination of modeling and content.

(2) Hardware: Compared with traditional products, 3D naked-eye led screens pay more attention to high refresh, high gray level, high dynamic contrast and smooth transition of surface/corner; In addition, the 3D naked eye led screen playback server needs to connect to a professional graphics workstation and configure a multi-graphics frame synchronization card;

(3) In terms of software:The 3D naked eye led screen needs a more professional decoder, which must be able to support the material mapping and correction function of the special-shaped display carrier, and support the underlying optimization of the decoding of high bit streams;

(4) Production requirements: The material production of 3D naked eye led screen depends on the surrounding environment of the LED display to achieve the best visual effect. Due to the different shape and surrounding environment of each 3D naked eye led screen, the video footage and presentation effect of each 3D naked eye led screen are also different.

3. What is the application principle of 3D naked eye led screen technology?

(1) Optical screen technology.

Light screen naked eye 3D technology is the use of a switch LCD screen, polarization film and polymer liquid crystal layer, using the liquid crystal layer and polarization film to produce 90 degrees of vertical stripes, the width between each stripe is only tens of microns, through the light can form a vertical strip grid mode, also known as "parallax barrier". Simply put, the principle of naked-eye 3D technology is to separate the visual screen of the left eye and the right eye, and the user can see a three-dimensional image.

(2) Cylindrical lens technology.

The naked-eye 3D technique of cylindrical lenses makes the image plane of the LCD screen located on the focal plane of the lens, so that the pixels under each cylindrical lens are divided into several sub-pixels, and the lens can project each sub-pixel in a different direction. When the user looks at the display from different angles, they can see different sub-pixels.

(3) Integrated imaging technology

The principle of the naxed-eye 3D technique of integrated imaging is to use a set of spherical, square or hexagonal lenses to produce the corresponding three-dimensional image, while providing horizontal and vertical parallax.

4. 3D naked eye led screen installation requirements?

(1) Location of the 3D naked eye led screen area: the core business district, commercial square, wide viewing space, and viewing distance before the 3D naked eye led screen can ensure that the display is clear, shocking, and undistorted, and there is enough information as a basis for selection.

(2) 3D naked eye led screen installation position: building wall and curved wall corner, about 10 meters high from the ground screen. Surrounding: Select the position set off by the background building to form the overall wall effect, the appearance is not obvious, there is illusion in reality, and there is reality in illusion.

(3) 3D naked eye led screen modeling: Design the structural modeling of the 3D naked eye led screen, and strive to have a three-dimensional modeling of the 3D naked eye led screen itself, such as arc, folded surface, curved surface and so on. It is required that the entire 3D naked eye led screen viewed from the same viewpoint has consistent brightness, no color bias and edge shadows, and smooth transition between the naked eye 3D led screen.

 (4) Detail processing: 3D naked eye led screen corner position is best arc transition, arc radius is about 0.5-1m. If the structural limitations of the building installation can only be made into corners, then the joint must be made small enough in combination with the product design and process requirements, and the display scene can be viewed in a space. You can boldly use the 3D naked eye led screen without a border to get a better display effect, or consider a black border.

5. 3D naked eye led screen production process?

Customer cooperation→Material collection→Video production→screen testing→sample submission;

Usually, a 30-second 3D naked eye led screen advertisement can be completed in 30-60 days; Naked eye 3D full color LED display large screen video is unique, each piece of 3D naked eye led screen needs to customize its own video. 3D naked eye led screen technology and the form of art have been used by more and more commercial projects to enhance the style of business and cutting-edge sense of the cost of the city's new landmark. Get a lot of exposure and attention.

 6. 3D naked eye led screen development.

In the field of LED display 3D naked eye led screen although said to have achieved results, but it is still in the development stage. Its research and development is divided into two directions, one is the development of 3D naked eye led screen hardware equipment, and the other is the processing and development of 3D naked eye led screen content. At present, the development of conventional 3D naked eye led screen hardware solutions and software materials is gradually on the right track, more and more 3D naked eye led screens also appear in our line of sight, but also become the current popular products, the place has become a network celebrity card, visible traffic is very considerable.

(1) The stage beauty display may become a new opening for the development of 3D naked eye led screens.

Although the naked eye 3D naked eye led screen is not as good as a variety of subdivided displays in traditional applications, in the application of the dance stage, with the development of visual display technology, it can highlight the display characteristics of the 3D naked eye led screen, so that it shines brightly. The unique naked eye 3D LED display mode creates a sense of spatial dimension. Combined with stage lighting, it creates an immersive lighting and movie feast, bringing a strong visual impact to the audience. In addition, in recent years, the demand for artistic performances has been on the rise, and the future prospects of the immersive visual performance stage are very broad. For nake-eye 3D LED display enterprises, it is recommended to start from the stage field of stage beauty, seek breakthroughs in the application and effect of 3D nake-eye led screens, and promote a substantial leap in industrial technology.

(2) Creative LED display or become a major opportunity for the rise of 3D naked eye led display.

In recent years, the creative led display has shone brightly, and many creative screens have brightened our eyes and added a lot of characteristic signs to the city. Various types of LED creative displays are also rising strongly. The realistic screen display effect of the naked eye 3D LED display can be integrated into the creative display to create a more realistic and shocking immersive experience scene.

(3) 3D naked eye combined with AR,VR technology to open up a broader sky.

The naked eye and Dled display has been applied more and more frequently in various exhibitions, AR, VR, holographic projection and other scenes. The naked eye and Dled display integrated with AR, VR and other technologies can not only achieve two-way interaction with users, but also present relevant content more vividly and directly, becoming an eye-sucking device for major application scenarios. Coupled with the further miniaturization of the point spacing of the small-pitch display and the deepening of the technology, coupled with the naked-eye 3D technology, not only brings more detailed display effects, but also makes up for the pain points of naked-eye 3D technology in the use of LED displays, opening a wider application space for 3D naked-eye led screens.
