How to create a naked eye 3D image LED display screen

Naked eye 3D LED display screen allows for viewing 3D video content with the naked eye without the need to wear 3D glasses or other 3D imaging devices. Compared with traditional LED displays, naked eye 3D LED displays have attracted much attention for their immersive 3D visual experience. It can transform urban buildings into landmarks, attracting more and more tourists. Obviously, advertisements on naked eye 3D screens have stronger expressive power and can bring more foot traffic and potential trading opportunities to large commercial centers.

This article will start from the visual principles of human 3D images and gradually analyze the basic principles and construction methods of naked eye 3D screens.

3D images in human vision

In fact, the slight positional difference between the two eyeballs in the human eye socket allows us to obtain two slightly different images simultaneously. One as the main image and the other as compensation; The two together constitute the spatial coordinate data of the 3D image. After passing through our brain's visual nervous system, we calculate these data and combine them into 3D stereoscopic images with positional difference information.

Based on the principle of human eye 3D imaging mentioned above, we have developed the following three approaches to achieve naked eye 3D imaging LED screens.

Using reference objects

The simplest way to convert a 2D LED display to a 3D LED display is to use a reference object. Usually, we can use lines or other images as background images to highlight the main content of the image with different layers, creating a three-dimensional visual experience for the image.

Curved LED display screen

L-shaped 3D LED displays appeared on two adjacent walls of a large building. It has two surfaces with a 90 ° structure. It utilizes the principles of our visual nervous system. One surface is used for the left eye, and the other surface is used for the right eye, so you can see clear and vivid 3D images from the corner area of the monitor without wearing glasses.

Professional designed 3D image content

Specially designed 3D visual content is another way to create immersive 3D visual experiences. 3D images designed and processed through special techniques can be directly played on flat LED screens and achieve 3D display effects.

High quality naked eye 3D LED screen

High quality naked eye 3D LED screens often require the following 5 characteristics:

Rich pixels

Rich pixels are a prerequisite for achieving delicate and three-dimensional content in naked eye 3D LED display screens.

High contrast and grayscale levels

Higher contrast, grayscale, and HDR capabilities are necessary conditions for naked eye 3D LED displays to produce rich and layered images.

Large viewing angle range

Naked eye 3D LED displays must provide a wide viewing angle range to meet the visual experience of different viewers in different positions.

Environment and climate tolerance

Naked eye 3D screens are usually installed outdoors, so excellent environmental and climate resistance is an indispensable quality.

low power consumption

Naked eye 3D LED displays are usually large in size and have a long running time, and low power consumption is necessary to gain more favor from users.
