With the continuous changes in market demand, LED smart projection gradually into the ordinary consumer's family. The price has also dropped from the initial value of nearly ten thousand yuan to a few thousand dollars today. This trend of improving product technology and at the same time reducing product prices has enabled more and more users to begin accepting smart projections. This acceptance is actually an invisible impact on the traditional television industry.
However, smart LED projection still has a projection label, and the first indicator to determine the projector is the brightness. Looking back at the history of projectors, it is not difficult to find that the lumens of smart projectors are almost proportional to the time, from 100 lumens in 2011 to 550 ANSI lumens in 2015. These are the constant progress of the times and the continuous breakthrough of smart hardware. As a projection of business, conference or teaching, although they are bright, they are expensive and large in price and size, and there are some extravagances for home use.
At present, the domestically produced projector has actually developed quite well. In the projectors I used, Cool Music is considered to be one of the most cost-effective ones. However, the models used originally were not powerful enough, and the effect was not shocking enough. Of course, a good company is in need of advancement. As far as I know, Cool Music Vision has recently launched its new projector S3 in JD. It may be the world’s first HD LED intelligent projection with brightness exceeding 1000 ANSI lumens. The machine is said to have a maximum of 1200 lumens. In order to confirm this brightness, it is said that CoolVideo has already planned to invite authoritative testing organizations and media to conduct notarized brightness tests, and even gave users a light meter to allow users to test on their own. It seems that they are very confident in their products.
Of course, the other parameters are also very flexible, such as automatic electric focus, finger-level precision gesture control, support for full 3D, 4K decoding, etc., in fact, the parameters given are tempting, not as good as actual detection. say. With the popularity of smart projection, I suspect that the real era of non-screen TV is coming. How should traditional TV and emerging smart TVs face?
