LED dot matrix module and LED dot matrix display?

Why are the pixel sizes (LED) of the LED dot matrix module and the LED dot matrix display so large? Only 3.0mm, 3.7mm, 5.0mm, in the big diameter pixel resolution and pixel density is very low, in view of a strong sense of particle, why not make the pixel diameter small? For example, 1mm below, so that the unit area of pixel density is very high, how to solve? What is a single LED dot matrix module?...


As for your first question, I think it is not a problem to be a small technician, but it depends on the demand. If the manufacturer develops a P1 product, nobody buys it. It is no good.

If the matrix module is broken, it will be changed. Small is to save maintenance costs. Also, it's easy to assemble.

The size of a single LED is the main limitation, and the too small size of the LED will not be encapsulated. Simply put, the single area of LED is dead. Too small a size to do. Of course, some of this is due to cost pressures, and if you have money, you can spread the entire panel.

Now the LED screen has indoor and outdoor parts. Whether indoor or outdoor, his characteristic is big! Developed for hyperopia, that is, the LED display is different from the LED LCD tv. You say the sense of particle does not exist.
