According to the characteristics of different LED displays, combined with the actual needs of users, choose the appropriate display.
In general, the φ5.0 monochrome display is used for the entrance and exit of the station, the dock, the large market, and the flow of the elevator. It has the advantages of clear font, low price and control of the fleet.
For banks, shopping malls and other occasions to display corporate image, advertising and other applications, the price is low, using φ3.75 dual primary color display. Requires display effect, using φ5 full color display.
For large halls, use φ5 double primary color display. Requires display effect, using φ1O full color display.
For the function definition of the service window of the business halls such as banks, postal services, and electric power, the method of using stickers in the past is very inflexible. Now use the φ3 or φ5 display to display the service function of the window at any time.
The outdoor display has higher requirements for quality due to the harsh environment. There are many factors to consider.
From the perspective of use, full color is the mainstream in the future. Because of its high brightness, full color, and all-weather work, it has an irreplaceable advantage, but the price is high.
From the application point of view, there are reasons for the existence of products that meet the needs of users. The dual-primary display screens occupy a large market with low price, mature and stable when the display text and color requirements are not high.
The orientation and distance of the outdoor screen play a decisive role in the price. The farther the distance is, the larger the pixel and the higher the brightness. It is much cheaper to face the northeast than to the southwest.
Misunderstanding in the procurement of LED display signs
First, the technical data issued by the LED material manufacturer indicates that the life of the LED illuminator is 10 million hours under ideal conditions. The ideal state refers to the time from the illuminating to the complete illuminating of the LED illuminant in the constant voltage and constant current state in the laboratory. 1 O 10,000 hours is equivalent to 11 years.
The amount of water in a wooden barrel is determined by the lowest board, and the LED display currently uses a civilian-grade device with a service life of no more than 8 years. The function of the display screen is to watch. When the display is lit only when it is clear at night, it cannot be said that it is qualified and valuable.
A car can be opened for 15 years, and if it is idle for 3 years, it will be scrapped. The environment and method of use have a significant impact on the life of the product.
Second, comply with the national standard
The general specification for LED displays is the 1995 ministerial standard. So far, there are still many companies that claim to meet the national standards. After 8 years of technological development, they will not look at the standards at that time. It is no longer a standard. For example, the out-of-control point, the national standard is 3/10,000, taking the φ3.75 indoor dual-primary display as an example. . Generally, the display with 640x480 standard resolution is 7 square meters, 43264 points per square meter, and there are 90 out of control points according to the national standard. Who is paying for such a display today?
Third, the software is free
The display industry is ubiquitous with the common problems of Chinese companies - only production is not developed. Currently only a few companies have genuine software. It is illegal to use piracy now.
Fourth, it depends on the performance price ratio. It depends on the performance price ratio rather than simply looking at the price.
Grayscale as a dual primary and full color display is an important indicator. The current market is flooded with 16-level and 64-level grayscale displays that pretend to be 256 shades of gray. Its control cost is only one-fifth of the control of 256-level grayscale. 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, to buy the best, all purchasing power comes from need. Meet the needs and have a certain lead. Blind pursuits will waste a lot of money to buy features that you don't need.
Seven, application is fundamental, as the application of the consultation, software upgrades, hardware maintenance, maintenance and repair, and ultimately the support of manufacturers.
