Home Theater Projector Tips: Several Common Laser Projector Problems Q & A

Different from the traditional projection, the laser projector adopts the most advanced laser light source technology, the laser belongs to the cold light source, the heat generation is not large during use, the temperature is low, so the life can exceed 20,000 hours, which is more than 10 times the service life of the traditional projector. Looking at the entire projection market, many projector brands have begun to develop and even launch their own laser projection products. However, not everyone has a deep understanding of laser projection, and here is a summary of several common problems about laser projection.

Q: When it comes to projectors, the first thing we think of is brightness, so how bright is the laser projector?
A: A single projection head provides brightness from 10,000 to 60,000 lumens. In fact, many systems are more than 30,000 lumens brighter, which is also the true value that laser projection can achieve. If more light output is required, any laser projection head can assemble a second projection head using Duo technology to achieve a brightness of 120,000 lumens.

Q: What are the advantages of laser projection system architecture?
A: The projection head and the light source are placed independently, a major advantage of the laser projection system is that it is easy to upgrade, and the laser module can be activated, prohibited, added or removed according to the desired brightness or primary color. Laser projectors can also achieve redundancy by using multiple laser modules, even if one module fails, as long as the other modules have no problems, the projector can continue to work; Another advantage is that the projection head can be installed away from the laser module, providing flexible deployment in demanding locations, allowing the light source to be installed in different locations, making it easier to manage cooling and noise and maintenance, while the modular design also simplifies projection system transmission.

Q: What is the better 3D effect projected by the laser projector?
A: The answer is yes. Laser projection effectively increases brightness and minimizes crosstalk between the eyes, which means that laser projection systems can bring a more natural, immersive and enjoyable 3D viewing experience to any application.

Q: What is a spot and how much does it affect movie watching?
A: Spots are visible imperfections in laser projection, which are scattered when coherent light reaches the projection screen, and manifest as unique video noise. The best solution at present is to choose the right screen material. In general, low-gain screens are better than high-gain screens, and screens (for polarized 3D systems) have the worst spotting performance.
