The technical data provided by the LED material manufacturers indicate that the lifetime of the LED luminaire is 10 million hours in an ideal state. The ideal state refers to the time during which the LED illuminant emits light to no light at all in a constant voltage and constant current state in the laboratory. 10 thousand hours is equivalent to 11 years.
First, LED life
The technical data provided by the LED material manufacturers indicate that the lifetime of the LED luminaire is 10 million hours in an ideal state. The ideal state refers to the time during which the LED illuminant emits light to no light at all in a constant voltage and constant current state in the laboratory. 10 thousand hours is equivalent to 11 years.
How much of a barrel's water is determined by the low board, LED display is currently used for civil-grade devices, the service life of not more than 8 years. As the function of the display is to watch, when the display is on only the night to see clearly, it is unable to show that it is qualified, has a use value.
A car can be opened for 15 years and will be scrapped if it is idle for 3 years. The environment and methods of use have a great influence on the life of the product.
Second, comply with the national standard
The general specification of LED display is the ministerial standard of 1995. So far there are many companies claiming to be in line with the standards. After 8 years of technology development, it is no longer a standard. For example, if the control point is out of control, the national standard is 3/10000. Take φ3.75 indoor dual-color display as an example. The screen with a standard resolution of 640x480 is generally 7 square meters, with 43264 points per square meter. According to the national standard, there are 90 out of control points. Who will pay for such a display today?
Third, the software is free
There is a common problem in Chinese display industry in the display industry - only production does not develop. At present, only a few companies have genuine software. It is illegal to use piracy right now.
Fourth, the cost performance depends on the ratio of performance to price. It depends on the price of performance rather than simply looking at the price.
Fifth, grayscale
Grayscale as a dual-color and full-color display is an important indicator. The current market is flooded with many 16- and 64-gradation display screens posing as 256 shades of gray. Its control cost is only one-fifth of the control of 256 gray scales. The easy way is to play a VCD with a more intense sports scene to see if the LED display can be seen clearly. 6. It is better to buy if you want to buy it. All purchasing power comes from needs. Meet the needs and have some advancement. Blind pursuit will waste a lot of money to purchase functions that you don't need.
Seven, practical application is fundamental, as the application of the consultation, software upgrades, hardware maintenance, maintenance and repairs, ultimately, manufacturers support. Source: Xi'an led/
