What is Naked Eye 3D Display? And How to do 3D LED Display?

Naked eye 3D technology mainly realizes its effect based on the principle of binocular parallax. As we know, there is a certain distance between human eyes, which makes the images seen by each eye slightly different when we observe an object. The brain can process these differences, allowing us to perceive the depth and three dimensionality of the object. naked eye 3D technology is a clever application of this natural phenomenon.

From the perspective of technical implementation methods, there are mainly the following types:

Firstly, parallax barrier technology. In this technology, a parallax barrier with a special pattern is placed in front of or behind the display screen. The pixels on the display screen are arranged in a specific way, that is, the pixels for the left and right eyes are alternately distributed. The parallax barrier can precisely control the light so that the left eye can only receive the pixel information prepared for the left eye, and the same for the right eye, thus successfully creating a 3D effect.

Secondly, lenticular lens technology. This technology installs a group of lenticular lenses in front of the display screen, and these lenses are carefully designed. When we watch the screen, the lenses will guide the different parts of the image on the display screen to both eyes according to our viewing angle. Even if our viewing position changes, this guiding effect can still ensure that both of our eyes receive the appropriate images, thus continuously maintaining the 3D visual effect.

There is also directional backlight technology. This technology relies on a special backlight system, in which LED light groups can be independently controlled. These backlights will illuminate different areas of the display screen according to specific rules. Combined with a high - speed response LCD panel, it can quickly switch between the left eye view and the right eye view, thus presenting a 3D effect picture to our eyes.

In addition, the realization of naked eye 3D also depends on the content production process. To display 3D images, 3D modeling software is required to create three dimensional objects or scenes. The software will generate views corresponding to the left and right eyes respectively, and will make detailed adjustments and optimizations to these views according to the naked eye 3D display technology used, such as pixel arrangement, viewing angle requirements, etc. During the playback process, the display device will accurately present the views of the left and right eyes to the audience, thereby enabling the audience to experience vivid and realistic 3D effects.

3. Features of Naked Eye 3D LED Display

Strong stereoscopic visual effect with significant depth perception. When 3D LED display is in front of you, viewers can feel the stereoscopic effect of the image without wearing 3D glasses or other auxiliary equipment.

Break through the plane limitation. It breaks the limitation of traditional two dimensional display, and the image seems to "jump out" of the 3D LED display. For example, in naked eye 3D advertisements, objects seem to rush out of the screen, which is highly visually attractive and can quickly catch the audience's attention.

High brightness and high contrast:

High brightness. LEDs themselves have relatively high brightness, so the naked 3D LED screen can clearly display images in various light environments. Whether it is outdoors with strong sunlight during the day or indoors with relatively dim light, it can ensure bright and clear pictures.

High contrast. The RTLED 3D LED display can present sharp color contrast and clear image contours, making the 3D effect more prominent. The black is deep, the white is bright, and the color saturation is high, making the picture more vivid and realistic.

Rich and diverse content:

Large creative expression space. It provides a vast creative space for creators and can realize various imaginative 3D scenes and animation effects. Whether it is animals, science - fiction scenes, or beautiful architectural models, they can be vividly displayed to meet the display requirements of different themes and styles.

High customizability. It can be customized according to different application scenarios and customer requirements, including the size, shape, and resolution of the 3D LED video wall, to adapt to the installation and use requirements of various places. For example, in different places such as building exteriors, commercial squares, and indoor exhibition halls, an appropriate LED display can be customized according to the space size and layout.

Good communication effect. The unique visual effect is easy to attract the audience's attention and interest and can quickly convey information. It has excellent communication effects in advertising, cultural display, information release, etc. In the field of commercial advertising, it can enhance brand awareness and influence; in the field of cultural and artistic, it can enhance the audience's artistic experience.

High reliability. The naked eye 3D LED screen has high reliability and stability and a long service life. It can adapt to harsh environmental conditions such as high temperature, low temperature, humidity, and dust. This enables the naked eye 3D LED display to operate stably for a long time in different environments such as outdoors and indoors, reducing maintenance and repair costs.

5. How to Do Naked Eye 3D LED Advertising?

Select high quality LED display. The pixel pitch should be selected considering the viewing distance. For example, a smaller pitch (P1 - P3) should be chosen for indoor short distance viewing, and for outdoor long distance viewing, it can be appropriately increased (P4 - P6). At the same time, high resolution can make 3D advertisements more delicate and realistic. In terms of brightness, the brightness of the display screen should be more than 5000 nits outdoors under strong light, and 1000 - 3000 nits indoors. Good contrast can enhance the sense of hierarchy and three dimensionality. The horizontal viewing angle should be 140° - 160°, and the vertical viewing angle should be about 120°, which can be achieved by reasonably designing the arrangement of LEDs and optical materials. Heat dissipation should be done well, and heat dissipation equipment or a housing with good heat dissipation performance can be used.

3D content production. Cooperate with professional 3D content production teams or personnel. They can skillfully use professional software, accurately create and process models, make animations as required, reasonably set cameras and viewing angles, and prepare rendering output according to the requirements of the 3D LED screen.

Software playback technology. Use content adaptation software to match and optimize the 3D content and the display screen. Select software that supports naked eye 3D playback and configure it according to the brand and model of the display screen to ensure compatibility and achieve stable and smooth playback.
