How to choose a fine pitch LED display?

2021-11-18 1,013

When buying LED displays, the precautions for choosing fine pitch LED displays: users should consider their own cost, demand, the scope of application and other factors. Before buying a fine pitch LED display, decide whether you really need a small spacing. It should be decided according to the actual situation.

  1. The prerequisite is "low bright high gray".

As a fine pitch LED screen of the display terminal, we must first ensure the viewing comfort, so when purchasing, the primary consideration is the brightness. Relevant studies have shown that, as an active source, the brightness of LED is twice that of passive luminescence (projector and LCD) in terms of human eye sensitivity. In order to make the eyes look more comfortable, the brightness range of fine pitch LED screen can only be between 100cd / m2 and 300cd / m2.

  1. When selecting point spacing, we should pay attention to the balance of "effect and skill"

Ordinary LED screens want to get good visual effects. Some people can only see the sight distance and fine pitch LED screens. Users can simply measure P2 through sight distance = sight distance / 0.3 ~ 0.8. For example, the viewing distance of P2 fine pitch LED screen is about 6m.

  1. Select the resolution and pay attention to the matching with the "front-end signal transmitter".

The smaller the dot spacing of the low spacing LED screen, the higher the resolution, and the higher the definition of the image. In practice, users want to construct a good LED display system with small spacing. While paying attention to the resolution of the screen itself, they should also consider the matching with the front-end signal transmission products.
