The Times is progressing and LEDFUL is advancing.
LEDFUL is a LED Display Manufacture with 12 years experience, specialized in Outdoor & Indoor Display, transparent display and floor display. For the new rising Naked-eye 3D display technology, LEDFUL provide our client with one stop solution. Here is the principle analysis, which can help you better understand the Naked-eye 3D LED Display.
Over the past few years, naked-eye 3D LED Displays have become more and more popular. Hundreds of cities across the country have successively created naked-eye 3D giant LED screens with local culture. At the same time, the naked eye 3D LED screen has attracted the attention of many led screen companies, and has also been cheered by the audience. Although the naked-eye 3D LED screen looks like a breakthrough compared with traditional display, it is quite "ordinary".
To make it simple, the LED Display naked-eye 3D technology is not a cutting-edge display technology, but this technology allows people to see vivid three-dimensional images without wearing 3D glasses. The naked-eye 3D working principle is to use the left and right eyes of a person to receive images from different positions, and then the brain superimposes and merges the information of the two images to form a picture with not only up-down, left-right, but also front-back, far -near three-dimensional images.
The common types of naked-eye 3D LED display technology are divided into shutter type and polarized type. Shutter type means that by dividing the image into two pictures by frame, two sets of pictures corresponding to the left eye and right eye are formed, which are displayed in a continuous interlaced manner. At the same time, the infrared signal transmitter will synchronously control the left and right lens switches of the shutter-type 3D glasses, so that the left and right eyes can see the corresponding picture at a certain moment.
Polarized type uses the principle of "vibration direction" of light to decompose the original image. First, the image is divided into two groups of vertically polarized light and horizontally polarized light, and then the 3D glasses use polarized lenses with different polarization directions on the left and right sides. In this way, a person's left and right eyes can receive two sets of images, and then synthesize a three-dimensional image through the brain. In comparison between the two, there are more applications for shutter-type glasses-free 3D LED screens.
The current naked-eye 3D technology does not give us a true naked-eye 3D LED display, but give a big LED screen that has a strong stereo effect when watching a specific video customized for the big screen at a specific angle, otherwise the image will be distorted. For example, when the viewer watch a straight line in a plane from any angle, the straight line is a straight line, but when the straight line is placed on a special-shaped screen, the straight line will become a diagonal line when viewed only at the same height as the eyes.
The naked eye 3D LED screens that have become popular in recent years are all composed of two images from different angles. The screen is folded by 90°, and the video material that conforms to the principle of perspective is used. The left screen shows the left view of the image, and the right shows the image. In the front view, when people stand in front of the corner and watch, they can see the side and front of the object at the same time, presenting a realistic three-dimensional effect.
