LED display selection guide According to the characteristics of different LED display screens, combined with the actual needs of users, choose the appropriate display screen. Generally speaking, φ5.0 monochromatic display screens are used to guide the flow of people at the entrances and exits of stations, terminals, large markets, and elevators. It has the advantages of clear fonts, low price, and cluster control. For applications such as banks and shopping malls to display corporate images and advertisements, low prices are required, and a φ3.75 dual-color display screen is required. For display effects, a φ5 full-color display screen is required. . For occasions with large hall area, use φ5 double primary color display screen. For display effect, use φ1O full-color display screen. For the function definition of service windows in business halls such as banks, postal services, and electricity, the previous method of using stickers is very inflexible. Now use the display screen of φ3 or φ5 to change the service function of the window at any time. Outdoor display screens have higher quality requirements because of the harsh operating environment. There are also many factors to consider. From the perspective of use, full color is the mainstream of the future. Because of its high brightness, full color, and all-weather work, it has its irreplaceable advantages, but the price is relatively high. From an application perspective, there are reasons for products that meet user needs. The dual-primary color display screen has low requirements for displaying text and colors, and has no blue color. With its low price, mature and stable occupation, the orientation and distance of outdoor screens in a large market play a decisive role in price. The farther away, the larger the primitives and the higher the brightness. It is much cheaper to face northeast than southwest. Misunderstandings in the procurement of LED display screens 1. Technical materials issued by LED material manufacturers indicate that the life of the LED luminous body is 10 000 hours in an ideal state. The ideal state refers to the LED luminous body emitting light under constant voltage and constant current in the laboratory To the time when no light is emitted at all. 10 million hours is equivalent to 11 years. The amount of water in a wooden barrel is determined by the lowest wooden board. The life of the LED display screen currently used for civilian-grade devices does not exceed 8 years. The function of the display screen is to watch. When the display screen is lit only at night, it cannot be seen that it is qualified and has use value. A car can be driven for 15 years, and scrapped if it has been idle for 3 years. The environment and method used have a great influence on the life of the product. Second, comply with national standards Third, the software free display screen industry generally has a common problem of Chinese enterprises-only production and not research and development. Only a few companies currently have genuine software. It is illegal to use piracy now. Fourth, it depends on the performance-price ratio rather than the price. Fifth, gray scale is an important indicator of dual primary colors and full color display screen gray scale. At present, the market is flooded with many 16-level and 64-level grayscale screens impersonating 256-level grayscale. The control cost is only one fifth of the 256-level gray scale control. The easiest way is to play a VCD of a more intense sports scene to see if it can be seen clearly on the LED display. Sixth, the best purchasing power comes from the need to buy. Meet the needs and have a certain lead. Blind pursuit will waste a lot of money to buy functions that you do not need. Seven, the application is basically as a consultation in the application.The software upgrade, hardware maintenance, maintenance and repair are indispensable to the support of the manufacturer.

LED large screen classification:
(1) According to the use environment, indoor display screen, semi-outdoor display screen, outdoor display screen
The general specification of LED display screen is the ministerial standard issued in 1995. There are still many companies claiming to comply with national standards so far. After 8 years of technological development, it is no longer the standard to look at the time. For example, the out-of-control point, the national standard is 3 / 10,000, taking φ3.75 indoor dual-color display as an example . Generally, the display screen with 640x480 standard resolution is 7 square meters, and each square meter is 43264 points. According to the national standard, there can be 90 runaway points. Who will pay for such a display today?
The main purpose of stainless steel cable tray is to organize and route cables and wires in a safe and efficient manner. It is an important component of any electrical system, as it helps to ensure that cables are not damaged or exposed to external elements. Stainless steel cable tray can be used in both indoor and outdoor applications, as it is resistant to moisture, chemicals, and extreme temperatures.
One of the key benefits of stainless steel cable tray is its durability. Stainless steel is a strong and long-lasting material that can withstand harsh environmental conditions and heavy loads. This makes it an ideal choice for industrial and commercial applications where cables need to be supported over long distances and in challenging environments.
