1: LCD Projector: Using liquid crystal display technology, the projector modulates light through the liquid crystal panel to project images. It is small in size and light in weight, suitable for presentations and home theater applications. 2: Single-chip DLP Projector: Using a digital micromirror device (DMD) as an optical engine, the projector modulates light by quickly switching micromirrors. Compared with LCD projectors, DLP projectors have better image contrast and color reproduction.
3: Three-chip DLP Projector: After separating the red, green and blue primary color beams, they are reflected on three DMD chips respectively, which can achieve higher color reproduction. It is used in high-end theaters and professional display fields.
4: Laser Projector: Using laser as a light source, it can provide high brightness, wide color gamut and long life. It is suitable for large conference rooms, theaters and outdoor applications.
5: LED Projector: Using LED as a light source, it has a longer service life and is more energy-saving and environmentally friendly than traditional bulbs. It is suitable for small and medium-sized application scenarios.
The main parameters of the projector include brightness (lumens), contrast, resolution, input interface, etc. Users can choose the appropriate projector model according to the application scenario and budget.
