The LED spherical screen has appeared in recent years, and its main purpose is to be able to view the content displayed on the screen in 360 degrees, display and watch in all directions, thereby bringing a new visual experience. The principle of LED spherical screen is? What are the characteristics and what related products are currently on the market? With such a question, the following is shared by LCF:

1. The Basic Principle of LED Ball Display Screen:

It is composed of core control module, rotating display module, wireless module, font module, motor drive module, and power supply. The fan blade is designed to be circular, and there is a circle of LED lamp beads on the fan blade. The light emitting color of the LED is monochromatic or multicolor. When the fan blade rotates around the central axis, it will produce a spherical surface, and all of them are on the spherical surface. LED, with the font software, when the fan blade goes to the corresponding position, the corresponding point is lighted, so that the display content of a spherical surface can be controlled.

 

2. Features of LED Spherical Screen:

1. Due to aesthetic fatigue and the demand for innovative and personalized display, the rotating LED spherical screen happens to be an unconventional product that gathers popularity. All the defects caused by using a flat video source to play on a three-dimensional spherical surface will be tolerated, just as people accept distorted photos taken with a wide-angle lens or fish-eye camera.

 

2. The resolution design of the LED spherical screen is the same as that of the ordinary LED display, that is, it is related to the viewing distance of the LED screen. Generally, if the viewing distance is 2.5 meters, it is recommended to choose the model P2.5 or P2, and the viewing distance is 6 meters. Choose P6 or P5, of course, the budget is sufficient, you can also choose more high-definition P4 or even P3. If it is used for outdoor viewing 10 meters away, you can choose the P10 model. Of course, this is a relatively vague choice. It is qualitative rather than quantitative. It depends on the specific site installation environment, audience and budget. Lianchengfa has withdrawn from the stadium LED display series products as early as 2016, the models include P3, P4, P6 and so on.

 

3. Types of LED Spherical Screen

1. Watermelon Peel LED Spherical Display:

It is composed of watermelon skin-like PCBs. The advantage is that the structure is intuitive and there are fewer types of PCBs. The disadvantage is that the north and south poles (that is, north of 45° north latitude and south of 45° south latitude) cannot play images normally, so the picture utilization is too low or the image is severely deformed. The reason is that the pixel points of all current image sources are arranged in rows and columns, and the pixel points of the north and south poles of the watermelon rind LED spherical screen are not arranged in rows and columns, but arranged in a circle, so It is difficult to display.

 

2.Triangular LED Spherical LED Advertising Display:

The spherical screen composed of a flat triangular PCB, commonly known as a football screen, overcomes the shortcomings of the watermelon rind spherical screen that the north and south poles cannot play images, so the screen utilization is greatly improved. The disadvantage is that there are many types of PCBs, limited by the honeycomb arrangement of pixels, and the dot pitch cannot be too small, and software writing is also more troublesome.

 

3. Six-sided LED Spherical LED Billboard:

The LED spherical screen composed of quadrilateral PCB is called the six-sided LED spherical screen. The advantage is that it is closer to a flat LED display, the minimum dot pitch is similar to that of a flat LED display, and there is little or no limitation, so the effect is much better than a spherical screen composed of a triangular PCB.
