The spherical led screen allows the audience to watch a full 360° viewing angle, which is different from the conventional LED display, and the details of the picture are easy to show. At the same time, the spherical led screen can directly project spherical objects such as the earth and football onto the display screen, giving people an intuitive and perfect Video enjoyment.
The LED Ball Screen is composed of a core control module, a rotating display module, a wireless module, a font library module, a motor drive module, and a power supply. The fan blade is designed to be circular, and there is a circle of LED lamp beads on the fan blade. The LED light-emitting color is single-color or multi-color.
When the fan blade rotates around the central axis, a spherical surface will be generated, and all the spherical surfaces are LED, with the font software, when the fan blade goes to the corresponding position, the corresponding point is lit, so that the display content of a spherical surface can be controlled.
Full-color LED Ball Screen is mainly used in museums, science and technology museums, enterprise exhibition halls, exhibition halls, outdoor spherical video advertisements, spherical lighting projects and other places. change.
The installation methods of the spherical led screen are diversified, which can be installed in different installation methods such as sitting type, hoisting type, inlay type, embedded type, etc. to meet the installation needs of different customers.
The introduction of LED spherical displays into the market has only appeared in recent years. Up to now, three types of LED spherical displays have appeared on the market. The production technologies of these types of LED spherical displays have all applied for patents, and some have even applied for PCT. International Patent.
The earliest spherical screen on the market, commonly known as the watermelon peel spherical screen, is composed of a watermelon peel-like PCB. North, south of 45° south latitude) cannot play the image normally, so the picture utilization rate is too low or the image is seriously deformed. The reason is that the pixel points of all image sources are arranged in rows and columns, and the pixel points of the north and south poles of the watermelon peel LED spherical screen are not arranged in rows and columns, but in circles, so Difficult to display. See Figures 1 and 2.
Triangular LED spherical screen The spherical screen composed of flat triangle PCB, commonly known as football screen, overcomes the shortcomings that the north and south poles of the watermelon peel ball screen cannot play images, so the screen utilization rate is greatly improved. The disadvantage is that there are many types of PCBs, and the pixel spacing cannot be too small due to the limitation of the honeycomb arrangement of pixels, and the software writing is also more troublesome. See Figure 3 below
It is a Maipu brilliance LED spherical screen composed of quadrilateral PCBs that appeared recently, and is known as a six-sided panoramic LED spherical screen. See Figure 4 and Figure 5. Its production method is also very simple. Now take the production of a spherical screen with a diameter of 1.5 meters as an example: divide the entire spherical surface into 6 surfaces with the same shape and size, and then divide each surface into 4 unit boxes with the same shape and size. 6 faces total 24. Each unit box consists of 16 PCBs with LED lights welded on the surface, and they are finally installed into a six-sided panoramic LED spherical screen.
The type of PCB board of the six-sided panoramic LED spherical screen is also less than that of the football screen. The pixel layout is closer to the normal flat LED display, and the minimum point spacing is also similar to that of the flat LED display. Therefore, the image sources that can be used to play on the ordinary flat LED display can be directly played on the six-sided panoramic LED spherical screen. The effect is much better than the spherical screen composed of watermelon rind PCB and the spherical screen composed of triangular PCB.
In terms of physical size, the entire spherical screen is composed of 6 surfaces with the same shape and size, and each surface is composed of 4 unit boxes with the same shape and size, as shown in Figure 5 and Figure 7. They fit into the flight case and are easy to disassemble for rental operators. Of course, in terms of software playback function, it can also play on the entire spherical surface with one video source like a watermelon rind LED spherical screen, such as a globe. It can also play 6 different video sources or the same video source on 6 sides of the same size (ie up, down, left, right, front, back 6 sides).
Of course, different video sources can also be played individually or in combination through software. This is especially important for dome screens larger than 2 meters in diameter. Because the height of a person is less than 2 meters, the effective viewing angle is only about 1/6 of the surface of the ball. See Figure 6 below:
The principle of the outdoor LED spherical screen is basically the same as that of the indoor spherical screen, the difference is that the outdoor LED spherical screen not only needs to be waterproof, but also may need to be installed with air conditioners for cooling.
