What is the difference between a laser TV and a projector? A complete analysis of one article

When people set up a home cinema, they often face two choices: Laser TV and home projector. They can achieve a large picture of more than 100 inches, bringing immersive experience. But what’s the difference between the two? Let’s see today. The home projector has a long history. In order to improve the viewing experience, many movie lovers have opened up a video studio, purchased high-end home projector, enjoyed the film in the dark, saw the dark details, color levels, and even realized the sense of touch and smell through the screen. < / P > < p > laser TV is a new product. It is a combination of intelligent ultra short focus projector and anti light screen, which overcomes the strict limitation of traditional projector for environmental light. In other words, it is the “living room improved version” of projector, which does not need to pull curtains and hoisting. Laser TV is more suitable for family daily viewing, gathering and playing games. < / P > < p > but any product is a comprehensive experience game in all aspects. When the price is the same, there is no absolute crushing. In order to adapt to different environments, laser TV and projector have opened different skill trees. < / P > < p > in order to have a beautiful environment, the laser TV needs to be placed on the TV cabinet in the living room. For example, BenQ’s latest laser TV has a projection ratio of 0.252, a projection distance of less than 50cm, and a short focus function, which can reduce the interference caused by people walking in the living room and reduce their own light loss. Ordinary projectors are mostly in the video room. They are usually hoisted and cast 100 inches in 2-3 meters. < / P > < p > the lens determines the projection distance. The shorter the distance, the more complex the lens design. The lens group needs to be polished and matched with each other more finely. Therefore, the laser TV needs to be equipped with a higher specification lens, such as BenQ laser TV i960l 4K short focus lens, with 19 lenses, is to achieve better analysis and make the picture sharper on the basis of short focus projection. Only in this way can we show the animal hair with distinct roots and show the subtle difference between soft and fluffy hair. < / P > < p > People’s perception of screen brightness is affected by the environment. Compared with the video room, the living room environment brightness is higher, so the brightness of most high-quality laser TV is about 3000 lumens. For example, the brightness of BenQ i960l reaches 3000m, which is much higher than 2000 lumen of home projector, so as to ensure good visual effect. < / P > < p > the screen brightness is not only affected by its own machine brightness, but also limited by the screen. For household projectors, white plastic curtain, glass bead curtain and glass fiber screen are usually used. These screens pay attention to color reduction performance and detailed display of gray scale, which can improve brightness to a certain extent. Laser TV must be equipped with anti light screen to deal with living room environment. Through the special optical structure, the anti light screen will reflect the light from the host TV to the audience’s location, filter out the ambient light, and improve the overall visual brightness. High brightness brings strong power to the picture. Thanks to this, the picture is no longer gray, as if it is alive. The service life of laser TV and projector is greatly affected by the life of light source. Ordinary household projectors mostly use mercury lamp light source, and the service time is more than 6000 to 8000 hours. As a supplement to the TV set, it can be used for watching movies irregularly. However, laser TV uses laser light source. In normal mode of use, BenQ laboratory has measured that the service life of laser TV light source is about 2W hours, which is about three times of that of ordinary projector. It can meet the needs of daily TV watching, family entertainment and other high-frequency applications. < / P > < p > to add, laser light source not only has a long service life, but also reduces the trouble of future maintenance and replacement of light bulb, and has concentrated energy and higher relative brightness. However, manufacturers have their own technology on how to use laser light source. For example, BenQ laser TV i960l mainly focuses on color reproduction to show the original mood and atmosphere of the film, and also takes the lead in launching dci-p3 wide color gamut. < / P > < p > for safety reasons, many laser TVs use eye protection induction devices to automatically detect the position of a person. Once someone approaches, the light source is turned off immediately to avoid direct light entering the eyes, and then the picture is restored. < / P > < p > again, for example, the bright base laser TV i960l can also automatically detect the ambient light brightness and adjust the screen brightness in real time. From morning to night, the effect is good. In short, laser TV is more suitable for living room and family entertainment, while home projector is more suitable for independent space viewing.
