The large selection of projectors is also due to the different projection technologies. There are LED, laser, LCD, DLP and LCoS projectors. You can quickly find out which technology is right for you with our list of the features of each projection technology. Finally, we have also summarized all the advantages and features of the devices in a table.
Home cinema technology at its best: with the DLP projector for the home
The light from the projector is projected onto the screen with the help of small reflective mirrors. The result of Digital Light Processing (DLP): particularly high-contrast images make home cinema a very special treat. This variant is also suitable for living room sizes - it's best to ask for advice!
High-end home cinema: the LCoS projector
This technology is based on both DLP and LCD technology. LCoS enables a high pixel density and an immensely high resolution up to 4K. These projectors are also suitable for 3D projections. Even if or precisely because this projection technology can make a visit to the cinema superfluous, LCoS projectors are located in the higher price segments.
Energy-efficient and durable: the LED projector
LEDs can be relied on for more than just room illumination: LED light-emitting diodes are also used in projectors and such models are the perfect choice for companies and educational institutions. Hardly any ventilation noise and no significant heating of the projector – it also does not consume much energy. The LED projector is particularly popular for flexible use as a mobile version. However, as it does not have the highest light intensity, it should primarily be used in rooms that can be darkened.
Also works in bright light: The laser projector
Innovative laser diodes deliver what LED diodes cannot: A high light output makes room darkening obsolete. In addition, laser projectors are just as energy-efficient as their LED siblings and are in no way inferior to them in terms of longevity. So if the spatial conditions of your company or educational institution make dimming impossible, the laser projector supports your presentations at any time of day and in any lighting conditions.
Bold colors for texts and diagrams: The LCD projector
Functions almost like a slide projector, but with the highest image quality: Liquid Crystal Display (LCD) technology separates light into the primary colors and reassembles the images via screens. With this technology, this projector variant enables you to achieve Full HD quality, which is best suited for presentation technology. However, the technology reaches its limits with fast moving images and color streaks can occur. LCD projectors are therefore rather unsuitable for video calls or home cinemas.
