What’s the Difference Between DLP, LED, and Laser Projectors?

DLP & LCD & Laser PROJECTOR - How They Work + TEARDOWN

  • DLP – Short for Digital Light Processing is a lamp-based projector that uses thousands of small mirrors to reflect light to produce colors and form the lifelike images you see on screen. They are best known to be portable, lightweight, yet very reliable.
  • LED – Or Light Emitting Diode, this type of projector uses LED bulbs to operate. Considered the most cost-efficient, they can run for up to 10,000 hours and consume less electricity.
  • Laser – Projectors of this kind use laser light to pass through a physical color wheel to emit higher image brightness on your projector screens. For customers who want really bright images, this is the best option. However, this is the most expensive amongst the three and the least portable in setups.

Frequently Asked Questions

1/ Since my lamp already failed, should I go ahead and change the lamp already?

There are two main reasons why a lamp may fail. It’s already used up and needs replacement, or your lamp is defective. If you’ve consistently used your projector for almost two years, you can change the lamp. But if it’s relatively new, we suggest you head to a service center to see if it can be fixed or replaced.

2/ I see my projector flashing an orange light. Should I also be worried?

Flashing orange lights usually signal standby mode or that the unit is shutting down. It does not indicate any sign of failure or issue compared to the red light.

Conclusion

A red blinking light on the projector signals different concerns. Before you panic and worry too much about your device, always check where the light source comes from because it’ll tell you the root of the issue. If you’re unsure how to resolve the blinking lights and how to restart your projector, it’s best to approach the service centers for checkups and repair.
