Why an LED is a Major Improvement
There has been an important innovation in projector technology. In the past, a large format projector used a bulb or a lamp. This technology was developed in the late 80’s and created a way to show large projections relatively easily. The Digital Light Projector, or DLP, was used for a long time but had its limitations. The equipment was expensive to purchase. Also, the lamp would need to be replaced periodically, which wasn’t cheap either. Because it used a lamp, the device would run hot and was prone to overheating. Lastly, stray light would wash out the display and make it hard to see. Today, we have Lampless LED projectors.
