Classroom Presentation Technology: Projection Versus Display

If you’ve been wrestling over which type of presentation technology is better for your classroom – projection or LED display, be aware that both systems have best-use case scenarios. There are pros and cons for each technology, so you may have difficulty choosing between them. The following comparison may help you decide.


Large Venue ProjectionProjectors have come a long way from their bulky classroom ancestors. Still, even newer projectors haven’t generally offered picture quality that can rival that of an LED display. That said, projectors are still the preferred mode for presentation in large classrooms, gymnasiums or auditoriums. With the projector, you’re assured that the image can be easily seen and read even by students sitting in the back of the room.

A number of improvements have been made in projector/screen technology in recent years, including the following:

  • interactivity allowing collaboration and encouraging student engagement
  • wireless technology
  • motorized screens
  • modular portable screens

Also, the physical properties of professional projection screen surfaces have been improved to enhance resolution, contrast and image brightness.

When a school wants to get as many classrooms equipped with AV technology as possible, projectors are traditionally a less expensive option. However, LED display costs have dropped in recent years so the two technologies have become more price competitive.


Educators might choose an LED display over a projector for the superior quality of the image. In some situations, such as a science lab, for instance, several displays may be required to present images and information simultaneously.

Another reason some educators might prefer LED is for interactivity. Using an interactive display for collaboration purposes ensures there is absolutely no shadow cast from the user. In addition, once set, the LED display typically doesn’t require any further calibration for touchscreen purposes.

Other factors in favor of the LED display:

  • There’s no need to turn off the lights in the classroom to see the image.
  • There’s no projector bulb to dim or burn out, requiring ongoing replacement.
  • No fan filters requiring maintenance or replacement.

On the other hand, the cost of LED systems large enough for auditorium-style classrooms may still be cost prohibitive. At Unified Technology Systems, we specialize in all types of presentation and can advise you as to the best solution for your classroom needs and budget.
