1, portability
Friends who have been in contact with the projector all know that traditional projection products, regardless of their size or weight, are called "big sized" and can only be fixedly placed or installed on walls or roofs. Less for the home, as to go out carrying is simply "to ask for food", we take several hot products as an example, the details are as follows:
As can be seen from the figure, the relatively light weight of the Optoma HD26 also reached 2.5kg, while the weight of the Panasonic BX621C was almost twice that of the former, reaching 4.9kg, and in terms of volume, these The products are relatively close. Although they belong to the smaller of the traditional projection products, they are still not portable.
Miniature projectors are different, these products are compact and light weight, can be placed in a backpack, bag, and even into the jacket pocket, with several well-known micro-projection products, for example, as shown below:
Compared with the above several traditional projection products, regardless of volume or weight, these micro-projection products are much smaller, the heaviest nut P2 but 1kg, VEZ Le BOX projector is only 0.15kg, its volume It is also the smallest of these products, so whether it is used at home or out to carry, micro-investment products are all right.

Second, light source
Different from the bulb light source used in the conventional projector, the LED light source used in the micro-projection products currently on the market. According to "China's projector market survey report for January-June 2016," the first four products in the first half of the projector market are all LED light sources. It can be seen that Chinese consumers pay more attention to LED pico projectors. high.
How DLP Technology Works
Although in terms of brightness, the LED light source may be slightly inferior to the bulb light source, the LED light source is better than the light bulb light source in terms of color, power consumption, and stability. The LED pico projector adopts TI's DLP display technology. The light is refracted by the color wheel to the DMD chip, and then the DMD chip projects the light after receiving the control signal. The DMD chip is composed of hundreds of thousands or even millions of micro-mirror units. Each micromirror is composed of a pixel, so that the light source presents more than 16 million colors and 256 grayscale levels; in terms of power consumption, the LED light source conversion rate is very high, and the energy consumption is only 10% of the light bulb. The power consumption is 80% less than that of a light bulb under the same power condition. In terms of stability, under normal circumstances, the light failure of LED light sources can be reduced to 70%, and the lifetime can be more than 20,000 hours, reducing the replacement frequency and other maintenance work. .

Third, practicality
Most of the ordinary projection products that we have come into contact with are located in classrooms, conference rooms and other places. It is usually necessary to connect desktops, laptops, and other devices via the HDMI cable. Otherwise, they cannot be used, so the functions will be relatively simple.

play games
Miniature projectors are different, usually these products are installed with Android operating system, such as JMGOOS nut projector, GMUI projector, VEZ projector VEZ UI, can be installed according to individual needs of applications, such as browsers, Video client, office software, games, etc., and can directly read U disk and various files on the memory card through the USB interface, TF card interface, connect the wireless network through wifi, so that the micro projector can directly play video online. Equivalent to the "smart set-top box + TV", but also an external Bluetooth handle for our game operations.
Fourth, audio and video effects
The reason why you choose to go to a movie theater instead of a home is nothing more than two reasons. First, the screen, because televisions, PCs, notebooks and other equipment can not show a cinema-like large-screen effect, the screen size is not enough, there is no full impact; The second is sound effects. Due to space limitations, home theater systems often cannot install sound systems such as movie theaters. For consumers who are interested in hearing enjoyment, they have no less than sound quality requirements.

Play TV shows
Large-screen projection is one of the characteristics of projection products. This can also be reflected in pico projectors. At home, we can project images directly onto the wall, and we can easily get a large screen of more than 100 feet. The screen effect can present more details, and the strong sense of substitution is quite powerful. Some brands of micro-projection products also support 3D functions, allowing us to watch 3D movies at home; sound effects, some of the hot selling Micro-projection products are equipped with professional-grade acoustic systems, such as polar meters Z4X Harman/Kardon, Cool LeTV S3 HiVi HiFi stereo, VEZ Le BOX's American Lou's cavity audio, etc. If these can not meet you, you can also add Bluetooth stereo, a small home theater. Therefore, micro-projection products bring not only a large screen, but also an immersive auditory experience.

V. Content resources
Only the hardware configuration is not enough, if there is no content enrichment, then the micro-projection product is only "unique." The reason why intelligent set-top boxes are sold well is that, apart from their own performance, a very important reason is the rich content resources, which is a good reference for micro-investment brands.
Polar Rice and Mango TV
Nuts and iQIYI
VEZ and CIBN
Examples of cooperation between micro-investment brands and content parties abound, with rice and mango TV in front, nuts and iQIYI, VEZ and CIBN behind. The performance of hardware and software shows the useless effect of “non-screen TVsâ€. Micro-investment companies are well aware of this. This kind of performance of “smart set-top boxes and TVs†also allows the micro-projectors to have the same knowledge as smart TVs.
