Can the size of full-color LED display be made arbitrarily? Can this be achieved? Come and have a look with us with such questions.
Theoretically, the size of LED display screen can be unlimited, but the reality is as follows:
At present, the outdoor full-color LED display screen is spliced by a waterproof box, and the size of the box is generally about 1 square meter. It is too large to facilitate transportation, installation and maintenance, and too small to increase the production cost and purchase cost. The indoor LED display screen is a unit board module splicing, and a simple box is also used.
1. Watch visual effects
LED display screen is mainly viewed by human eyes, and the visual distance and effect of human eyes are limited. The viewing distance is long, the screen is large, the viewing distance is short, and the screen is small.
For example, the viewing distance of indoor LED display screen is generally a few meters or even tens of meters, so it is decided that the indoor screen area is small, generally within 20 square meters. For the outdoor LED display screen, the viewing distance is far, generally tens of meters, so the screen area will be relatively large, more than 30 square meters.
2. Price cost
At present, the price of full-color LED display screen is thousands of yuan per square meter. Others include steel structure, accessories, control card, etc. The larger the price, the higher the budget. Theoretically, it can be infinitely larger, but the price will be an amazing number, and no one can afford it.
3. Maintenance issues
The larger the, the more difficult it is to maintain and manage. Once a problem occurs, the maintenance and troubleshooting is also more troublesome. It is also a great test for manpower.
4. Installation location and environment
This indoor space is limited, needless to say. For outdoor, there is not enough open space to support the screen can be large enough.
Therefore, only from the above four aspects, it can be seen that it is impossible to be arbitrarily large in real life, and at present, the largest display screen can reach thousands of square meters, which is a limit.
