Thin profiles can be created to be 5 cm thick instead of the usual 9 cm, and there are a few on-demand custom boxes that can be made to be more than 10 centimetres thick for greater power output.
Regardless of screen size, a standard LED display is less than 10cm thick; however, a 4m rear projection system might require 4-5 m of depth. In many 24/7 control rooms, rear-projection LEDs are the favored technology. They have a very small bezel, outstanding image quality, and a very long lifespan.
Choosing Between Ultra-Thin and Rear-Projection
Below are some factors to consider when choosing between a front-projected ultra-thin LED screen and a thick rear-projected screen.
Location
Where would be the ideal location for your LED display? If there is not enough space for a projector to be placed behind the screen, then you should pot for a front-projected screen.
Ambient Light
How much ambient light is there in your space? If the ambient light level is uncontrollable, you should consider a thin front projector with a greater lumen rating and an ALR (ambient light-rejecting) screen. Even though it will cost more, front-projection installation may still be less complicated and more affordable than rear-projection once construction-related costs are taken into account.
Text
A front-projected image will provide you with a modest advantage in fine detail when displaying a lot of text as opposed to a rear-projected image.
Aesthetics
If you have enough space and would like to hide as much of technology as possible, then a thick rear-projected LED screen will be more suitable.
Noise
If there is a problem with noise levels, rear projection may prove advantageous. The projectors can be hidden in another room to lower ambient noise levels in settings like museums, theatres, churches, and art galleries.
