The core technology of DLP projector is to realize imaging by reflecting light through millions of independently controlled micromirrors. Mainly divided into single-chip, dual-chip and triple-chip DMD systems, corresponding to portable devices, splicing display walls and high-brightness scenarios, covering education, home theater, large venues and other applications.

The device utilizes a closed optical path design to reduce dust interference and features high contrast, fast response (16 microseconds) and compact size. Color generation relies on either color wheel beam splitting or tri-color independent chip technology, and supports resolutions from 1080p to 8K, with brightness ranging from 3,000 lumens for home use to 50,000 lumens for engineering [4]. Product innovations include LED light sources (lower maintenance costs), 3D displays (120Hz refresh rate) and micro-projections (wearable device integration). The education sector relies on high definition and 3D interaction to enhance teaching and learning, and the professional market realizes ultra-large area projection through multi-chip systems.

The image is sharp and the pixel grid is not obvious. High contrast, deeper blacks, and more layered images. Sealed structure, not easy to get into the dust, relatively long life. Fast response time, dynamic images (e.g., watching sports events, playing games) are smoother.
