Choosing the right display technology is crucial for making a strong visual impact. While projectors and video walls have been popular, direct view LED displays offer sharper images, better reliability, and less maintenance. Let’s explore why LED is quickly becoming the smarter choice.
Ambient Light
Front projection is compromised when ambient light, that is light from windows, skylights and/or lighting fixtures intrudes on the auditorium, sanctuary, etc. Projected images will appear faded as ambient light will wash out the projected image. Colors will not be sharp or deep. Blacks will not look intense. While rooms can be darkened with shades, curtains, turning off lights, sitting in the dark is not the optimal atmosphere for a corporate presentation or church service.
LED displays on the other hand are not affected by ambient light. Colors always appear sharp and deep. In most indoor applications LED displays can be run at 50% brightness or even less and still be intense enough to not be impacted by ambient light.
Shadows
As is often the case, a presenter in a corporate meeting setting may want to be up at the screen. A presenter in front of a projection screen will cast a shadow on the screen. Standing in front of an LED display has no impact on the images shown.
Rear Projection and Lack of Space
Rear projection solves the problem of a presenter casting shadows on the screen. The downside to rear projection is the amount of space needed behind the screen. To implement a rear projection system, you need to account for at least 4-5 ft. behind the screen for the projector. Space is at a premium in most corporate environments so rear projection is not a viable solution in most applications. An LED display can be mounted on the wall and only takes up a couple of inches of space at most.
Display Size Limits
The image size a single projector can project is limited. Beyond a certain size, you need to use multiple projectors. This requires skilled technicians and software to blend the image between the projectors being used to create a single image. There are no limits on the size an LED displays can be, as it is as simple attaching more LED cabinets in both the height and width as needed, with “edge blending” a non-issue.
Stability
When using multiple projectors to achieve a large-blended image, physical location of the projectors to each other is critical. If a single projector is moved for any reason all the projectors have to be re-aligned, which is a time-consuming tedious undertaking.
Aesthetics
Seeing a projector up on the ceiling or multiple projectors in an array on the ceiling isn’t the most aesthetically pleasing sight. With an LED display, you see the LED display and nothing else.
Fan Noise
All projectors have fans. Fans make noise. Some projectors are louder than others, but they all produce some fan noise. There are no fans in an LED display, so an LED display will not distract the presentation with noise the way projection will.
Maintenance
Projectors require more maintenance than LED as they contain expensive bulbs that have a short lifespan and many moving parts. While newer generation projectors using laser rather than bulbs have cut down on needed maintenance for projectors, the cost and maintenance of projectors is still more than what is required with LED displays where little or no maintenance is needed.
Simulation Using Cylinders and Domes
Using projectors for simulation is a complex, expensive undertaking. Ambient light creates shadows, and images that are not sharp. The expense of replacing bulbs adds up. But the most serious problem, in using projection, is that if after having set up multiple projectors, they are jostled or moved slightly the process has to start over from the beginning, which can be a very frustrating, time-consuming process.
AVOE uses flexible LED tiles to create curved LED video display domes and cylinders that have seamless rounded curves. Ambient light has no effect on these LED video tiles. As images are fed directly to the LED screen, any movement in the simulation area is irrelevant. The high resolution that was needed in certain simulation applications that could be achieved with LED flex tiles was lacking. However, flex LED tiles can now achieve a very small pixel pitch of P0.9 and as a result the arc minutes LED flex tiles can hit are very low and the resolution can meet any demand.
