The technical data issued by the manufacturer of LED display indicates that the life of LED luminous body is 10 million hours under the ideal condition. The ideal condition refers to the time when the LED luminous body emits light from light to no light under the condition of constant voltage and constant current in the laboratory, 10 million hours is equivalent to 11 years.

The technical data issued by the manufacturer of LED display indicates that the life of LED luminous body is 10 million hours under the ideal condition. The ideal condition refers to the time when the LED luminous body emits light from light to no light under the condition of constant voltage and constant current in the laboratory, 10 million hours is equivalent to 11 years. The amount of water contained in a wooden bucket is determined by the lowest wooden board. Nanjing LED display currently uses other equipment for the people, with a service life of no more than 8 years. The function of the display screen is to watch.

A car can be driven for 15 years. If it is shelved for 3 years, it will be invalid. The environment and methods used have a great impact on the longevity of commodities.
So far, many companies claim to conform to national norms. In the eight years since the development of science and technology, the norms at that time are no longer norms. For example, at the point of out of control, the national standard is 3 / 10000 φ 3.75 indoor dual primary color display screen as an example. Usually, the 640×480 standard resolution display screen is 7 square meters, 43264 points per square meter, and there can be 90 out of control points according to the national standard. Who pays for such a display today.
There is a common problem in Chinese companies – only production without development. At present, only a few companies have genuine software. Nowadays, it is illegal to use piracy.
As a dual primary color and full-color display, gray is an important goal. At present, the market is full of many 16 and 64 gray display screens pretending to be 256 gray. Its control cost is only 1 / 5 of that of 256 gray levels. The simplest way is to broadcast a VCD of a violent sports scene and check whether it can be seen clearly on the LED display screen.
