The LED spherical screen has only appeared in recent years. Its main purpose is to be able to view the content displayed on the screen in 360 degrees, and display it in all directions, thus bringing a new visual experience. LED spherical screen principle ? What are the characteristics, what are the related products on the market now? With such questions:
First, the basic principle of LED spherical screen:
It consists of a core control module, a rotary display module, a wireless module, a font library module, a motor drive module, and a power supply. The fan blade is designed to be round, and there is a circle of LED lamp beads on the fan blade. The color of the LED is monochromatic or multi-color. When the fan blade rotates around the central axis, a spherical surface is generated, and all of the spherical surfaces are LED, with the font software, when the fan leaves to the corresponding position, the corresponding point is illuminated, so that the display content of a spherical surface can be controlled.
Second, the characteristics of the LED spherical screen:
1. Due to the aesthetic fatigue and the demand for innovative and personalized display, the rotating LED spherical screen is just a new and popular product. All the defects caused by playing a flat video source on a 3D spherical surface will be tolerated, just as a distorted photo taken with a wide-angle lens or a fisheye camera is accepted.
2, LED spherical screen resolution design is the same as ordinary LED display, that is, related to the viewing distance of the LED screen, generally if it is 2.5 meters away, it is recommended to select the model P2.5 or P2 model, 6 meters to watch, it is recommended Choose P6 or P5, of course, the budget is sufficient, you can also choose a higher-definition P4 or even P3. If it is used for outdoor viewing from 10 meters, you can choose the P10 model. Of course, this is a vague choice. It is qualitative rather than quantitative. It depends on the specific installation environment, audience and budget.
Third, LED spherical screen types
1. Watermelon skin LED spherical display:
It consists of a watermelon-like PCB. The advantage is that the structure is intuitive and the type of PCB is small. 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 screen utilization rate is too low or the image is severely deformed. The reason is that all the pixel points of the current image source are arranged in rows, and the pixel points of the north and south poles of the watermelon ball LED screen are not arranged in rows, but in a circle, so Difficult to display.
2, triangular LED spherical display:
The spherical screen composed of a flat triangular PCB, commonly known as a soccer screen, overcomes the shortcomings of the north and south poles of the watermelon screen, so the screen utilization is greatly improved. The disadvantage is that there are many types of PCBs, and the pixel points are limited by the honeycomb arrangement, and the dot pitch cannot be too small, and the software writing is also troublesome.
3, six-sided LED spherical display:
The LED spherical screen composed of a quadrilateral PCB is called a six-sided LED spherical screen. The advantage is that it is closer to the flat LED display. The minimum point spacing is similar to that of the flat LED display . The limit is not limited or almost unlimited, so the effect is much better than the ball screen composed of triangular PCB.
A new rule from the Drug Enforcement Administration (DEA) threatens to upend the American hemp industry, and could even result in criminal prosecutions for manufacturers of CBD and delta-8 THC products.
The DEA says the [interim final rule," issued Aug. 20, is simply a matter of adjusting its own regulations to account for changes to the Controlled Substances Act that were mandated by the 2018 Farm Bill (or Agricultural Improvement Act) that legalized hemp and CBD production. The new rule [merely conforms DEA`s regulations to the statutory amendments to the CSA that have already taken effect," says the agency. The new rule doesn`t break any ground, according to the DEA.
But many experts on cannabis and hemp law say the DEA rule creates a potential pathway the law enforcement agency could use to prosecute hemp processors and producers of CBD (cannabidiol) and delta-8 THC (or Δ8THC) products. There are two issues: partially processed CBD, and [synthetically derived" delta-8 THC.
