The popularity of modern laser projectors is only gaining momentum. This is due to the expansion of their functionality, improving the quality of the output picture and adding SmartTV. Thus, for some users, the choice between a large-screen TV and the laser projector itself may become relevant, since, at almost the same price, the projector can produce a much larger image. In the publication below, I will try to analyze the main characteristics of a laser projector that you should pay attention to when choosing tripod projector screens.
Projector types
Lamp projectors
This is the most common type of projector today, such popularity came to these projectors primarily because of their low price. Such models use mercury or xenon lamps, which lose their brightness over time and require replacement, and the relatively low brightness of the lamps can also be attributed to the disadvantages of such devices, which is the reason for the use of such models in dark rooms.
LED projectors
Such models are equipped with LED lamps, which increases energy efficiency, reduces the overall dimensions of the device, increases its durability, and also provides a fairly good color rendering. However, such models also have their disadvantages, which are associated with relatively low brightness. This is due to a number of features of the use of LED lamps as a light source for projectors and manual projector screen also can be use.
Laser projectors
This type of projectors is by far the most high-tech, they provide the highest brightness of the reproduced picture, and the highest possible color reproduction. Laser projectors combine many more advantages, which I will discuss later in the publication, and, in my opinion, such projectors are one of the best choices for organizing your home theater.
Principle of operation and main characteristics
How light turns into a picture
In a nutshell, regardless of the type of projector, they are united by the basic principle of operation. The light source produces a luminous flux, which is directed to a special matrix. The matrix, in turn, either opens or closes certain cells, thereby the passing stream of light forms the necessary picture. But everything is not so simple here, for example, to form a high-quality color image, manufacturers immediately install three matrices for basic colors (red, blue, green). Another design solution may be to install a matrix in the form of a rotating disk, each sector of which is responsible for its own color. I will add that in laser projectors, engineers managed to expand the capabilities and improve the characteristics of brightness and contrast. Some models use additional filters, for example, yellow.
Brightness and Contrast
One of the main characteristics when choosing a projector is the brightness of the light flux and contrast. Here it is worth paying attention that when choosing brightness parameters, you should focus on ANSI-lumens, and not on the usual lumens. Both parameters reflect the brightness of the light flux, however, the measurement technique is different. In a nutshell, the ANSI-lumens settings are used directly in the projectors. It is better to read more about this in a separate article, which can be found by searching. So, for example, Chinese manufacturers often indicate the brightness of their projectors in ordinary lumens, these are a kind of peak values \u200b\u200b(Peak-lumens). So, when choosing, I recommend paying attention to the ANSI-lumens parameters, which are kind of more objective.
As for brightness, I’ll add a few examples. A projector with a luminous flux of about 1000 ANSI-lumens is suitable for use in well darkened rooms. If we are talking about laser models, then they can be purchased with values from 2000 ANSI-lumens, such models can already be used in brighter rooms or during the day. Here I think it is clear that the higher the value of ANSI-lumens, the better.
Focal length
Mostly laser projectors can be installed very close to the screen, and this is also their plus, but it all depends on the desired image size. When choosing a laser projector, you can pay attention to the so-called ultra-short throw models, which can be installed almost close to the screen (15-20 centimeters) and get the largest possible picture.
Permission
When choosing a modern projector, just like when choosing a TV, you need to pay attention to the resolution of the resulting image. Most laser models on the market have a resolution of at least FullHD, while more expensive ones are capable of producing an image with Ultra-HD resolution. It is also worth paying attention to the presence of HDR technology, which provides a more saturated color picture.
Smart TV function
At the moment, laser protectors, like their budget representatives of another type, are equipped with the Smart TV function. Here, when choosing, you should pay attention to whether Smart TV supports your favorite streaming services. Almost all projectors have access to the Internet via Wi-Fi and the ability to control using a special remote control.
Sound
Initially, protectors were used exclusively for picture reproduction, however, some modern models are equipped with relatively powerful speakers with 3D sound support and 40-watt speakers with 4.2-channel support. This provides high-quality sound that can be compared with the sound of the built-in acoustics of any TV. But still, when organizing a home theater, you can’t do without an additional speaker system.
Is it possible to replace a TV with a laser projector
Typically, TVs can be purchased with a diagonal of up to 90 inches, in rare cases in stores you can find TVs with a screen of more than 90-100 inches, and the price of such models is already much higher. As mentioned above, a modern projector can easily provide a picture with a diagonal of up to 130 inches, and laser projectors can also provide excellent picture quality that is fully comparable to modern TVs. Especially, the choice towards a laser projector looks more relevant when organizing a full-fledged home theater. So yes, a modern laser projector can replace a TV.
Conclusion
Summing up, I would like to go over the main advantages of a laser projector once again. Firstly, this is a large screen diagonal of up to 130 inches, with a high-quality and bright picture, and secondly, it is worth noting the price, which will be significantly lower compared to a TV with a diagonal of more than 75 inches. I would also like to note the mobility of the projector and the ability to easily transport it from place to place if necessary. Another thing worth highlighting is the design of projectors, especially models with ultra-short throw distance. Such models are obviously designed for installation in the most visible place, so manufacturers take care of their appearance. Perhaps that’s all, thank you for your attention.
