In recent years, the size of the projector is small, the screen is large, and the sense of immersion is strong when watching movies, and many families use projectors instead of TVs, or in professional video rooms, use projectors as the main electrical appliances for home audio-visual entertainment.
Among them, the laser projector has always been the best light source for mid-to-high-end projectors with its pure light source and high brightness, especially after using ALPD technology to solve the problem of speckle.
Laser TV is also a type of laser projector. According to the description of the laser TV specification and standard issued by the Ministry of Industry and Information Technology, laser TV refers to the display equipment that uses laser projection display technology and is equipped with a special projection screen to display radio and television programs or Internet TV programs.
The biggest difference between laser TV and laser projector,In addition to displaying radio and television programs,And Internet TV programs,It is also equipped with a special anti-light curtain,And the brightness unit is nits,Not the projector's CVIA、IOS、ANSI Lumens and other brightness standards。
Laser TVs generally have ultra-short focal lengths, and the projection ratio is generally less than 0Within 3:1, it is necessary to project a picture of about 100 inches, which generally requires 20-50cm. This kind of short-throw projector can reduce the loss of light source due to the relatively short projection distance, and at the same time, the movement of personnel will not interfere with the image.
However, the size of laser TV is relatively large,And the position is relatively fixed,It needs to be aligned with the screen,Can't be moved at will。 Laser projectors generally have a long focal length, projecting a 100-inch picture, which usually requires a distance of 2-3 meters. Moreover, the placement of the laser projector is relatively casual, which can be projected, side-projected, hoisted, etc., and can be placed and used at will according to the situation of the room.
In addition, in addition to the host and screen, laser TV also comes with its own sound system, and it can also be equipped with a high-quality sound system, which is not comparable with a projector.
In terms of resolution, at present, whether it is a laser TV or a laser projector, DLP display technology is commonly used, which uses the DMD chip produced by Texas Instruments as an imaging device to reflect light through thousands of tiny lenses to achieve imaging.
Due to the high ** of the DMD chip, the projector that realizes the native 4K resolution should be more than 2-30,000, although the current 4K resolution generally adopts XPR jitter technology, which reduces the cost of the projector with 4K resolution a lot, but it is still relatively high.
At present, projectors are generally based on 1080p, and the same is true for laser projectors. 4K resolution laser projectors have gradually increased in recent years, but ** generally higher, if the budget is not high, you can consider choosing a projector with a resolution of 1080p.
And laser TV is mainly based on 4K resolution,Plus equipped with a special anti-light screen,The effect of the display is obviously much better,But**It is also relatively expensive。 Take 75-inch laser TV as an example,**Generally more than 6000 yuan。
In addition, due to the pure color and high brightness of the laser light source, the projector of the early three-color laser light source will have obvious speckle or oversaturation problems, which greatly reduces the clarity and resolution of imaging.
At present, many laser projectors or laser TVs use ALPD technology, using rare earth fluorescent materials and hybrid laser technology, which solves the speckle problem of laser projectors, and at the same time has high efficiency and low cost. Therefore, whether you choose a laser TV or a laser projector, choose a product that uses ALPD technology, and the experience is better.
In addition, if you buy a brand laser projector or laser TV, the quality of the product and the after-sales and use experience are guaranteed to a certain extent. Among them, the brands of laser projectors are mainly dangbei、XGIMI、Nuts、Epson and other brands。
The brands of laser TVs mainly include Hisense、Vidda、Fengmi、XGIMI、Epson and other brands,You can choose products of this type of brand when buying。
In recent years, in the field of laser panchromatic display technology in the laser projection industry in China, it has a complete chain of independent intellectual property rights, especially in the field of all-solid-state trichromatic laser, laser display and other key devices and complete machine technologies have their own patented technologies.
And laser projectors have gradually entered ordinary families,At the same time, national policies also encourage the development of the laser display industry,In the future, whether it is laser TV or laser projector, the product experience will be better and better。
