So your church has decided to install a LED wall over projection.
Now the next hurdle is to figure exactly what manufacturer or model of an LED wall would be the right fit for your worship space.
The manufacturers highlighted in this slideshow include Absen, Barco, Chauvet, Christie, Daktronics, Elation, Mega Systems, PixelFLEX, Planar/Leyard and ROE Visual.
For churches seeking a product that will last for many years to come, six of the ten are rated with a lifespan of 100,000 hours, those being the Absen N4, Christie Velvet Merit Series 4.0mm, Daktronics 4mm SMD, Elation EPT6iP, Leyard uEV5 and the PixelFLEX FGi-6. The remaining four in the group, the Barco V4e GII, Chauvet C6, Mega Systems I-501 and ROE Visual BO3, each rate at half that, at an estimated 50,000 hours.
Even with what seems to be a significant difference in lifespan, it should be noted that all of them should be seen as rating highly in that regard.
To give you an idea what "only" 50,000 hours amounts to, imagine leaving the LED wall on 24/7 immediately after it is installed. Using the 50,000 yardstick, that model would last nearly six years in such a hypothetical scenario.
And we all know that such equipment will often be used frequently, but by no means to the extent of being used nonstop each and every hour.
Looking beyond the rated lifespans of each of the ten models, another key aspect to judge them would be based on their pixel pitch ratings. But when three of the models each come in rated at a 4.0 mm pixel pitch, only for the range between the ten models to run just 3.47 mm to 6.67 mm, it's hard to envision any configuration within a church where any of them would fail to achieve the optimal viewing distance desired for the congregation.
Depending on where the LED wall is installed, it can result in a model's viewing angle spec to be deemed crucial. There is a notable difference between a few of the models with regard to that calculation, with the Daktronics rating at an impressive 170 degrees vertically and horizontally and the Leyard model right behind with a rating of 160 degrees, both horizontally and vertically. Scoring lower in this area, though, was the Barco unit, which rated at just 100 degrees on its horizontal calculation, while the Elation model rated slightly better, at 120 degrees both horizontally and vertically.
Lastly, another data point worthy to review when comparing models, is each model's refresh rate. Some LED walls can cause frustrating "flickering," when the content from the LED wall is being recorded by a video camera, which can occur when the LED wall model's refresh rate is below 1,000 Hz. In such a scenario, line breaks can appear in photos taken by a still camera, which then looks like "flickering" when capturing video. None of the ten models shown in this slide show have a refresh rate below 1,080 Hz, so that issue seems unlikely to occur with any of them. But one model in particular, the Christie model, does stand above the rest, with a stellar 3,200 Hz refresh rate, to definitely eliminate any such chance that will occur.
