Buying a projector means choosing between three different light sources and three imaging technologies, then making sure the projector has enough brightness for your environment and desired screen size, not to mention enough contrast and color accuracy to enhance your viewing experience. For newbies, this is a hassle.
why a projector?
Simply put, when it comes to watching movies or playing video games, bigger is better. Sitting at an appropriate distance from an image of 100 inches or larger allows for more detail to be seen, allowing for an immersive viewing experience. Other than that, unlike TVs, which illuminate your eyes with bright emitted light, projections are reflections on the screen. This is how we look at most objects in life, and we see ambient light bouncing off of them. Therefore, the projected image will be more natural.
Projection light source
The light source of projection is mainly divided into lamp, laser and LED projection.
laser. Solid-state laser light engines are taking over the commercial projector market. One advantage of laser projectors is that at the highest brightness levels, they tend to be easier to use than lamp- or LED-based models, and offer great color accuracy. In addition, no lamp replacement is required during the projector's 20,000-hour lifetime, and maintenance requirements are low or no replacement required.
LED projection is the light source for the vast majority of small projectors, they can be well below 100 lumens and no more than 1500 lumens, and they generally get their maximum brightness from LEDs, which often result in bright but oversaturated colors.
