Outdoor LED display screens are generally installed in squares, building exterior walls, stadiums and other places, as information carrier, advertising media carrier. These displays have high brightness, long color mixing distance, high degree of protection, waterproof and UV resistance, making them suitable for long distance viewing. Therefore, the purchase of outdoor LED display should take into account the screen waterproof and lightning protection, heat dissipation and low temperature environmental protection as well as display brightness, viewing angle and other viewing factors.
High quality image
In terms of image quality, the main indicators are: gray processing power, color processing power, refresh rate, contrast, resolution, and so on. As we all know, the higher the parameters, the better: the higher the gray processing power, the richer the brightness of the picture; the higher the color processing power, the more beautiful the color quality of the picture; the higher the refresh rate, the better the continuity of the moving picture; the higher the contrast High, the more prominent the details of the picture; the higher the resolution, the more delicate the picture. Users should pay great attention to these parameters when purchasing LED display screens, and LED bright screen outdoor display has high refresh rate, high contrast, high resolution, rich colors, etc., which meets these requirements.
Easy to install and maintain
The outdoor LED display should be easy to operate and maintain. The outdoor installation display is often exposed to wind and sun, and the four seasons are replaced by dust, which makes the working environment worse. When the electronic device is subjected to rainwater intrusion or wet, the short circuit or fire of the single device may be caused, thereby causing unnecessary loss. On the basis of the display and control separation of the LED bright display, the display part adopts the modular design of the light bar, and the light bar can be easily disassembled and maintained separately, which greatly reduces the maintenance difficulty.
Audience visibility
The audience is wide, the distance between the line of sight is long, the field of vision is wide, and the ambient light changes greatly, especially if it is exposed to direct sunlight. In order to ensure long-distance visibility under strong ambient light conditions, ultra-high brightness LEDs must be used; the display medium uses a new wide viewing angle tube, which has a wide viewing angle, pure color, consistent coordination, and a lifetime of more than 100,000 hours. The outer packaging of the display medium is currently the most popular with a rectangular cylinder with a cover, a silicone seal, and no metallization; its appearance is exquisite and beautiful, durable and durable, with direct sunlight, dustproof, waterproof, high temperature resistance, and short circuit protection. "Five defenses" features. The LED bright display uses patented technology (ZL20092020579.2) to adjust the downlight angle of the light bar according to the installation height and the best viewing angle of the human eye, ensuring the optimal viewing area distribution you need;
Waterproof and lightning protection
The display screen is installed outdoors, often exposed to the sun and rain, the wind blows the dust cover, and the working environment is bad. If the electronic equipment is wet or seriously damp, it may cause a short circuit or even a fire, causing malfunction or even fire, resulting in loss. Therefore, the selected display screen body and the joint between the screen body and the building must be strictly waterproof and leakproof; the screen body should have good drainage measures, and once the water accumulation occurs, it can be discharged smoothly. The LED bright display structure components are all made of special surface treatment technology, which has good moisture and corrosion resistance; the electronic circuit adopts three anti-treatment processes to further protect the product from dust, moisture and corrosion, ensuring that the products are extremely strong. Weather resistance, long-term use in harsh outdoor environments.
Outdoor LED displays may be subject to strong electrical and magnetic attacks caused by lightning. Therefore, the lightning protection device should be installed on the display and the building after the optional display. The main body and the outer casing of the display are well grounded, and the grounding resistance is less than 3 ohms, so that the large current caused by lightning is discharged in time. The LED screen has a professional installation team, based on the specific conditions of the field, choose the best lightning protection program.
Heat dissipation and low temperature
The ambient temperature varies greatly. When the display is working, it must generate a certain amount of heat. If the ambient temperature is too high and the heat dissipation is poor, the integrated circuit may not work properly or even be burned, so that the display system cannot work normally. Install the ventilation device to cool down and make the inside of the screen. The temperature is between -10 ° C and 40 ° C. An axial fan is installed on the back of the screen to discharge heat; an industrial-grade integrated circuit chip with an operating temperature between -40 ° C and 80 ° C is selected to prevent the display from starting due to the low temperature in winter. The LED bright display has a light bar structure, and more than 90% of the transmittance provides an excellent ventilation environment for the display, which is perfect for heat dissipation.
Now you should know something about the characteristics of the outdoor display? LED display screens are not only costly, but also cause great losses to users if they fail during use. Therefore, when purchasing, you must shop around and choose products with both quality and service guarantees.
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.
