The holographic 3D advertising machine is a new type of advertising display device. Its main advantages are low energy consumption, cool effect, full of technology, and higher display performance than traditional advertising machines.

The holographic 3D smart screen is a display device that utilizes the principle of human vision persistence (POV) technology to achieve 3D visual enhancement by rotating images of ultra-high density LED lights. Since only LED is used as the light source, there is no border and no fixed screen, so the line of sight is not affected at all, and the content can be clearly seen. The whole image is suspended in the air, full of scientific sense, even if it moves left and right, it does not affect the viewing effect. One of the naked eye 3D.

3D fan screen is mainly used in advertising media, exhibition and exhibition areas, and can meet the 2D and 3D video playback. Built-in WIFI module to support network interconnection. It has the characteristics of playing 3D video, realistic life, long life, low energy consumption, easy to install and use, high use value and wide applicability. Widely installed in shopping malls, cinemas, hotels, restaurants, exhibition halls, specialty stores, subways, airports and other indoor and semi-outdoor occasions.

The realization of the 3D advertising machine mainly utilizes the persistence factor (POV technology) of the human eye vision, and densely arranges and rotates the image through one or several columns of LEDs.

In more detail, the visual effect of light on the retina remains for a while after the light stops. Although the recognition accuracy of the human eye is very high, the time required for the optic nerve to transmit images to the brain is 1/24 second. It is this factor that can be used to form a continuous picture when the switching speed of multiple freeze frames reaches 24 frames (the 24 frames referred to here are the frame rate directly displayed to the human eye, not the frame rate transmitted by the machine to some machines). . The frame rate of the holographic 3D advertising machine is generally around 30 frames per second, which means that the time of each frame freeze is 1/30 second, so the imaging effect is realized. At the same time, when the device is imaged, the LED lights are illuminated, and the surrounding outer casing is dark and does not emit light. When the device is in operation, the human eye will only receive the light staying, while the dark color will not be able to be too fast. The brain distinguishes, so that the display effect will only stay on the light displayed by the LED, thus achieving the effect of aerial imaging. Then use 3D effect material, which achieves the effect of holographic 3D imaging.
