Another one bites the dust
The imagers in DLP projectors typically have a sealed DMD chip and cooling is done through the back of each imager device without hindering the optical path. This means that the DMD is shielded from the cooling air and dust particles. It makes sure your viewers will see a clear and dust-free image.
And it also reduces the time and money required for upkeep of your projector. LCD projectors typically do not have sealed optics, are more sensitive for dust build-up and require periodical replacement or cleaning of the air filters to avoid dust spots on the projected image.
Long live the DMD
In addition, DLP projectors are considered more durable with guaranteed image uniformity, color accuracy and light output over time. Not only because the design prevents dust build-up but also because DMDs are micromechanical structures. They don’t change or fade over time.
The organic character of the liquid crystal modules, on the other hand, makes the LCD imagers sensitive to light, blue light in specific. Meaning that after long exposure, their performances will reduce in image quality.
All imaging technologies have of course their own pros and cons and the ideal choice always depends on several factors. The DLP Digital Light Processing projectors offer a better image representation, especially at higher resolutions, higher brightness capabilities, better predictability and stronger reliability. For these reasons, the projectors are typically used for mid- and high-end applications such as large venue projections by the rental industry and immersive experiences in the fixed install market.
