How to choose a good LED display?

LED display is not cheap. How to choose a LED display with good cost ratio? Let’s discuss this from 7 points: The maximum brightness, color temperature, refresh rate, wave length, viewing angle of the LED, PCB design, and average power consumption.

Today we will talk about the maximum brightness.

First of all, we must have an idea that the brightness is not the higher the better. Higher brightness means higher purchase and power cost, and faster component decay. The maximum brightness is the brightness of the LED display when it shows the maximum grayscale and brightness under a certain surrounding illuminance. The maximum requirement is different for different service environment. Normally if the display faces the direction of sunshine, 4000CD/m2 is good enough; if it directly faces the sunshine, 7000CD/m2 is bright enough to show qualified images under sunshine. If the display faces the west or east direction, 5500CD/m2 is good enough.

Theoretically, a display with 5500CD/m2 maximum brightness can meet the most using environment. It is the best cost-ratio maximum brightness.
