LED screen or projector?

16 Sep, 2020 | LED screens

The current trend is to use LED screens more frequently to reproduce large format video projections, and in this way to gradually replace older and older projectors.

We will analyze the pros and cons if you are considering using one technology or another and why both indoor and outdoor LED screens are increasingly used in all sectors.

Brightness measurement of LED screens and projector

The projector and the LED screen are different items, so two different brightness measurement methods are used.
The brightness of the projector is in LUX and the brightness of the LED screen is in NITS.

3426 LUX = 1 MIT

The NIT brightness of LED displays is almost 3,5 times higher than that of LUX.
This means that it can operate at 20-30% of its brightness, which prolongs the life of the LED display.

In short, the projector is based on a backlight principle that measures the intensity of the light source on a surface and the LED screen uses a direct lighting system that indicates the brightness of the screen radiating itself.

One of the main differences between both technologies is the brightness provided by the LED screen is much higher than the brightness of the projector, and therefore we can compensate for the influence of external natural light, an advantage to be able to use LED technology in any environment. . In contrast, the projector is used where there is no direct light, which limits its use.

In addition, economically, the wear of the projector is greater with the corresponding maintenance and replacement of its parts. On the other hand, LED screens require a higher initial investment, but since they are composed of modules, they can be easily and quickly fixed on site, using cheaper components.

Regarding the resolution, since the LED each pixel is a beam of light, projectors tend to have a higher resolution in relation to the playback area, although its surface is limited. On the other hand, the resolution of LED screens evolves very quickly day after day, reaching a pixel pitch of less than 1 mm.

Without a doubt, LED technology will prevail over projectors and we will see this technology more and more in our daily environment.
