1. Generally, the display module is about 10 ~ 15mm. This data is for reference only. After all, the modules of different factories will be slightly different, but the difference will not be too large;

What is the thickness of LED display screen

(1) simple box is used.
the thickness of module + box can reach 100 mm
(2) the thickness of waterproof box can reach 160mm
(3) the thickness of die cast aluminum rental box may be only 80mm
this needs to be confirmed according to the actual application

3. In addition, it also involves whether to keep the maintenance channel
(1) the maintenance channel should be reserved, and the thickness of 500-600mm should be reserved behind the screen.
(2) not reserved. The whole screen is only 90mm thick the brightness of the LED electronic display screen refers to the luminous intensity of the display screen when it is working normally.
the unit area of the display screen is CD / m2 (i.e. the luminous intensity of how many CDs per square meter of the area, "CD" is called candela in Chinese, The higher the brightness of the LED electronic display, the better the brightness of the image, The brightness of indoor video screen is generally between 200 and 1200 CD / m2.
the brightness of outdoor video screen is generally between 3000 and 7000 CD / m2.
the brightness of LED electronic display screen is a more difficult index to measure (because the test instrument is expensive).
generally, it can be calculated by testing the light intensity of LED display screen, For example, when a 2500 point / m2 outdoor LED full-color display is white balanced,Ten pixels were randomly measured by LED light intensity meter, and the average light intensity of red tube was 420 MCD; The green tube is 1620mcd; When the light intensity of blue tube is 285mcd, the brightness of the display screen is 2500x (2x420 + 1620 + 285) / 1000=6862.5cd/m2, 6862500mcd/m2, because the screen has 2500 pixels per square meter, and each pixel has 2 red tubes, 1 green tube and 1 blue tube.
