How to Make Glasses-free 3D LED Display
Optronics Industry | 2023-12-25

Glasses-free 3D LED display, also named as naked eye 3D LED display allows us to watch 3D video content without wearing 3D glasses or other extra equipment. Comparing with traditional 2D LED display, glasses free 3D LED display attracts great attention because of its more immersive 3D visual experience. It can transfer a city building to a landmark and attracts more and more visitors. It performs much better for advertising and of course, brings more potential purchasing and transaction for commercial center at metropolises.In this article, we’ll start from how we human beings see 3D images, step and step learn basic principles of glasses-free 3D LED display.

How we human beings see 3D images


In fact, the slight position differences of the two eye balls in our eyes get two slightly different images of a same object, one works as the main image, the other as a compensation; and the two together form spatial coordinates data for 3D images. And our brains, a complex nerve system, calculate these data and combine them into a 3D image.


Based on the above described 3D image system in our eyes, we’ve 3 ways to make glasses-free 3D LED displays. Let’s go deeper with below paragraphs.


3 Ways to make glasses-free 3D LED display


  1. Using reference objects


Using reference objects is an easy way transform a 2D LED display to a 3D LED display. In this case, we usually divide image into different layers by lines, or other background images to create 3D visual experience. For example, the famous SMTown uses a gray background to display 3D waves on the 3D wall display.


  1. L-shaped 3D LED display


An L-shaped 3D LED display appears on the two neighboring walls of a large building. It has two surfaces in a 90° construction. It uses the principle of our visual nerve system. One surface for the left eye and the other for the right eye, so you can see clear and vivid 3D images without wearing glasses from the cornering area of the building.

  1. Special 3D effect videos


Specially designed videos for 3D display effect is another way for creating immersive 3D visual experience. With special 3D effect videos, we can realize 3D display even on a flat 2D LED display.


What makes a good 3D LED display


To make a good 3D LED display, we should take below factors into consideration.


  1. Rich pixels


Rich in details is the basic requirement for a good 3D LED display, which means you need rich pixels for the screen to carry out the best naked eye 3D visual experience.


  1. Higher Contrast and gray scale


Higher contrast, gray scale and HDR features are essential for a glasses-free 3D LED display to produce rich layers of 3D video contents.


  1. Wide viewing angle


A good 3D LED display should offer wide viewing angles for audiences watching it from different positions.


  1. Higly weather resistant


Installed outdoors, weather resistant quality is a must for glasses-free 3D LED displays.


  1. Low Power consumption


Power consumption is also a factor you should consider since a glasses-free 3D LED display is usually large and operates a long time to draw public attention.


Kinglight LED display lamps for glasses-free 3D LED displays


Kinglight supplies a wide variety of LED display lamps and some of them, such as the 1820N-A series, 1820-GB series, and 1820-CS series, are suitable for making glasses-free good 3D LED displays.


No doubt that in the future, glasses-free 3D LED displays will be the mainstream for advertising. It can transfer buildings to city landmarks, deliver brand messages worldwide and deeply into audiences, and bring your brand to a global level or top level of the industry.
