What is Naked Eye 3D_ LED display large screen naked eye 3D_ LED display screen refers to a large LED display screen that allows the human eye to perceive stereoscopic display effects without the use of visual aids such as polarized glasses. This is a brand new media presentation method that utilizes MINI distributed optical matrix 3D fusion screen to overlay professional 3D frequency visual materials, presenting visual shock and impact with perfect display effects, breaking through artistic boundaries and overturning traditional flat video display modes. Naked eye 3D_ The Technical Principle of LED Display Screen: Naked Eye 3D_ LED display is based on the installation location and audience distribution of the LED display screen, using the MINI distributed optical matrix 3D fusion screen with ultra-high definition golden viewpoint as the perspective image carrier. It uses the pointing light source naked eye 3D technology to set the main perspective range, calibrate the viewing angle and distance of the audience, reconstruct the 3D model according to the perspective elements, basic voxels, and composite voxels, reverse the content perspective relationship, and then perform the perspective element points, lines In the perspective reverse engineering of the face, a basic reverse engineering was carried out from the perspective of graphics, and the corresponding inverse conversion algorithm model was provided. The scene application structure of the display screen was designed in reverse with the model. Then, through repeated fine-tuning of the algorithm, the 3D images were sorted into the eyes of the viewer, forming a parallax between the left and right eyes, thereby achieving the best effect of naked eye 3D display. Naked eye 3D_ The position selection and structural design requirements of LED display screens are based on naked eye 3D_ The principle of LED display large screen technology and the optimal viewing requirements, therefore, there are the following requirements for selecting the location of the LED display large screen: regional location: core commercial area, commercial square, with a wide viewing area and distance in front of the LED large screen, which can ensure clear, shocking, undistorted display, and sufficient information as the selection basis. Installation location: At the corner of the building wall, on the curved wall, approximately 10 meters above the ground level screen. Design the structural design of the large screen, striving to have a three-dimensional shape of the screen itself, such as arcs, folds, curved surfaces, etc. It is required that the brightness and color of the entire display screen viewed from the same viewpoint should be consistent, without color deviation or hood obstruction, and the transition between display surfaces should be smooth. Surrounding environment: Choose a location with a background building to create an overall wall effect, with an unobtrusive appearance that reflects reality and illusion. Display screen design: The optimal design mode is right angle+arc transition (outer arc), where the corner position is transitioned by an arc with a radius of about 0.5-1 meters. If the installation structure of the building is limited to making edges and corners, then the joint should be made small enough in combination with product design and process requirements, and can be used in display scenes viewed from a distance. You can boldly adopt a display screen without edges for better display effect, or consider black edges; At present, PH4 and PH3 have narrow modules that can achieve perfect arc splicing;
