Packaging and accessories
▲ Different from the common popular paper packaging, the sandwich structure of black and silver is low-key but not vulgar. Huayi's packaging box really brightens my eyes.
▲ The pure black plastic box is exquisitely made, with only the logo of hmovie, which makes it simple. As the overall color matching is black, the packaging of Huayi TV V5 is also known as the "Pure Black Treasure Box".
▲ The surface of the packing box is covered with a protective film to protect the upper cover from scratches.
▲ Open the upper cover, it is a protective sponge.
▲ Uncover the sponge layer and you can see the pure white body and the silver remote control lying in the "cradle" of the sponge. The white fuselage stands out against the black protective layer.
▲ For silver white remote control, the key layout is not crowded.
▲ There is a button battery compartment on the back.
▲ Huayi remote control is Bluetooth 2.4G, which is convenient and flexible. There is no specific direction for remote control. Unfortunately, there is no built-in Bluetooth receiver, and external receiver is required.
▲ A USB interface is occupied virtually.
▲ Power adapter, glasses and other accessories are separately placed in two kraft paper packaging boxes.
▲ Considering the multiple use of 3D glasses, the upper and lower packaging similar to iPhone is adopted. There are two notches in the middle for users to open. It can be seen that Huayi pays attention to details. Each glasses is equipped with a separate dust-proof bag, which instantly improves the product grade.
▲ Active shutter 3D glasses have the advantage of providing high-quality 3D display effect. An infrared receiving window can be seen on the front of the glasses.
▲ There is an inconspicuous power button on the top of the glasses.
▲ In order to make up for the increased weight of the active shutter 3D glasses that need batteries, the legs of the glasses have been specially treated, which conform to human mechanics, very light and comfortable, and children have no burden to use them.
▲ Family photo. It includes the main body of the camera, remote control, power adapter, 3D glasses, dust-free cloth, instructions and 3D glasses instructions.
fuselage
▲ The whole machine is light and compact, and its three-dimensional size is 186 × 115 × 28mm. Maybe this number is not very impressive, but the volume of 0.000598m3 must be eye popping.
▲ The front of the machine body is made of UV polishing paint and 7 common touch buttons. Compared with similar products on the market, Huayi V5 does not bulge because of the lens, and the machine body is very flat.
▲ The bottom is also a UV polished baking varnish panel, which is very smooth and flat. There is no ugly bottom air inlet design of traditional micro projection, which avoids the machine bottom acting as a vacuum cleaner, thus affecting the service life of the machine. There are two rubber pads near the back. The front is an adjustable support base. This design makes V5 have very low requirements for the use environment.
▲ Both sides of the machine are the inlet and outlet and the heat dissipation port. Based on the convection principle, large area full heat dissipation is achieved, and the secondary heat dissipation is conducted through the golden metal heat dissipation grille.
▲ There is a manual focusing wheel on the left, and the user can adjust the imaging effect by himself.
▲ The back space layout interface is fully utilized, and TF card and dual USB interface are provided for data interaction. In terms of video output, there are common HDMI and optical fiber output, in addition, there is a traditional 3.5mm audio interface.
▲ There is only one lens on the front panel, and the simple and beautiful design of the fuselage can be seen at a glance. The design of no air outlet on the front face also fully avoids the bad experience of hot air blowing directly into the head when the machine is placed behind.
▲ According to the official display, V5 uses an all glass lens with an all metal lens barrel, which solves the problem of out of focus.
▲ The side of the fuselage is the drawing process of aluminum magnesium alloy, which adds a lot of beauty. The frame runs across the fuselage, and the white UV polished top has a more tough flavor under their auxiliary name.
Small science popularization of projection
Projection mode
At present, there are mainly two types of core technology of the projector products, which occupy the leading position in the market, namely, the monolithic LCD technology projector and the full digital DLP intelligent 3D projector.
▲ The projector based on monolithic LCD technology uses the photoelectric effect of liquid crystal, that is, the arrangement of liquid crystal molecules changes under the effect of electric field, which affects the transmittance or reflectivity of its liquid crystal unit, thus affecting its optical properties, and producing images with different gray levels and colors. It adopts the technology of single LCD screen and high-power packaged LED lamp. The driver is generally the chip of Taiwan Morningstar Semiconductor Mstar, a famous TV chip manufacturer. This technical product generally has low contrast, low brightness, and obvious flashlight effect. It is an entry-level product of household projection television.
▲ All digital DLP intelligent projector, which uses DMD (Digital Micomirror Device) digital micromirror as imaging device, is an all digital reflective projection technology. The first feature is digital advantage. With the adoption of digital technology, the gray level of the image is improved, the image noise disappears, the image quality is stable, and the digital image is very accurate. The second is reflective advantage. With the application of reflective DMD devices, the total optical efficiency of imaging devices is greatly improved, and the contrast and brightness uniformity are excellent. The DLP projector has high definition, uniform picture and sharp color. It has powerful functions such as a projection screen of 200 inches, illumination lumens of more than 1500 lumens, 2D and 3D one button conversion.
The projection technology adopted by Huayi V5 is DLP. However, the brightness is only 300 lumens, which is average in strong light environment, but the imaging effect is good in weak light and at night.
Projection size
Huayi V5 supports a maximum projection of 200 inches. According to the data in the manual, there is a prerequisite for obtaining this giant screen effect. The projection distance needs to reach 5.16 meters., Therefore, 73 inch images can be projected at 2 meters, which is the advantage of short focus, and larger images can be achieved in limited space.
Product heat dissipation
Heat dissipation has always been the top priority of projection products. Especially in such a small body, it is also a technical activity to do a good job in heat dissipation system. Huayi officially announced that its copper tube fin for heat dissipation is a return type design, which can quickly take the heat of optical and mechanical products away from the heart of the machine, ensure that all heat generated by the machine can flow out from the exhaust outlets on both sides, and ensure the stable operation of the machine. In addition, the secondary heat conduction effect of the metal frame outside the fuselage can be combined with the regenerative cooling system to achieve good heat dissipation effect of the small fuselage. According to the actual measurement by the author, the machine has been running for more than 2 hours and only feels warm.
service life
When it comes to projectors, what we associate with is that they have a short life, but Huayi V5 has achieved 30000 hours. Here we can calculate that if you use them for 8 hours a day, V5 can be used continuously (30000/365/8=) for 10.2 years, and after 30000 hours, only the brightness attenuation is not a direct scrap.
Hands on experience
▲ Although it is equipped with all glass lens and all metal lens barrel, which ensures the problem of out of focus to the greatest extent, V5 is still equipped with a manual focus knob to meet the needs of users to a greater extent. From the boot screen, it can be seen that the overall clarity of the projection screen is relatively satisfactory, and the edge and corner virtualization is not obvious.
▲ Compared with traditional video cameras, Huayi V5 not only has an incomparable advantage in size, but also has the most valuable built-in Android system. Users can fully understand it as a "video camera with built-in TV box". Only WiFi network is needed to enjoy online video live broadcast and massive applications.
▲ Huayi V5 UI style is similar to the Metro of Win8, with clear colors and simple and clear card like large icons.
▲ In terms of film source, V5 itself is a platform product, but it integrates three mainstream video databases, namely Taijie, Full Convergence and BesTV, and massive resources can meet the needs of users.
▲ Take the popular "full aggregation" as an example, there are rich video categories and the latest video push.
▲ The signal sources of hundreds of TV stations in the live broadcast function let users completely say goodbye to the shackles of wired signals. The most important thing for users is that these signal sources are completely free.
▲ The resolution of V5 is 1280 * 800, which supports 1080P signal display, and its image quality can fully meet daily needs. More importantly, for projection equipment, the viewing distance is basically several meters away, which greatly reduces the shortcomings of resolution. The movie watching experience is excellent. You can be in the scene under the big screen.
▲ V5 is based on Android system. Users can install Android applications on the market by themselves. For geeks, the most eye-catching reason is the "ES File Browser".
▲ For young people who are young and energetic, the game system is essential, and under the large screen, the game is more realistic.
▲ In terms of system structure, the local menu signal source and USB media player have exclusive interfaces and are automatically divided into music, video HDMI、 Photos and other categories, with clear hierarchy.
▲ Compared with similar products on the market, Huayi V5 has an unusually rich setting interface.
▲ In the network settings, there is only wireless connection, and V5 is not equipped with network cable socket. It can be seen that Huayi is more inclined to small size in terms of volume and connectivity.
▲ For a projection device, the projection option is essential.
▲ Users can set the brightness of projection according to the environment. The brightness of V5 video can reach more than 300 lumens, all thanks to the application of DLP technology. As we all know, the heat dissipation process of the high gloss machine is extremely difficult. With such a small size, we can see the efforts behind Huayi's team.
▲ Four projection modes are provided: front projection, rear projection, inverted coin projection and inverted rear projection.
▲ Audio and Bluetooth settings.
WIN8 style card style, simple and clear structure of large icons, local menu signal source, exclusive interface of USB media player, common settings, game and application menus, and related video library. In addition to adding projection settings, this structure is the same as mainstream TV boxes on the market, easy to use, and is undoubtedly a great benefit for small white users.
3D playback effect
▲ The application of all digital DLP technology enables V5 to support the playback of 3D movie sources.
▲ The solution of using backlight module components supplemented by image quality enhancement technology ensures the fullness of the picture color. There are no tips during 3D playback, which is a barrier for Xiaobai users.
▲ In combination with the randomly presented active shutter 3D glasses, it provides high-quality 3D display effect. Through actual viewing, there is a kind of visual spectacle that leaps out of the big screen. The picture is no longer dark and dazzling, but very fresh and vivid. The 3D screen display effect is excellent, giving people an immersive feeling.
However, in the 3D playback mode, switching 3D mode will lead to probabilistic jamming, which may be due to imperfect engineering machine optimization. In addition, when playing the local movie source, the remote control button will be stuck in probability if it is pressed too fast.
"Flying screen" function
▲ Compared with similar products on the market, the biggest highlight of Huayi V5 is the "flying screen" function similar to the TV box. You can push the screen to the projection screen through mobile phones, tablets, PCs and other products to fully expand the video resources. (It is necessary to show mobile phones, computers, and the same scene as the projection screen after the flying screen. Please refer to the following scene)
▲ There are three ways to push the screen, and the Apple phone is the simplest. You can use Airplay directly. Click the push screen icon in the upper right corner. Of course, the premise is that the projector and mobile terminal are in the same WiFi environment.
▲ There is a QR code on the video camera flying screen interface, which can scan and download the flying screen software - Watcher Movie, and Android phones can download the flying screen software for use.
It is worth mentioning that when watching online video on the mobile phone, the camera will automatically parse the video URL after pushing the screen through dlna. At this time, even if the mobile phone application is turned off, the camera will not affect playing online video, completely liberating the mobile phone.
▲ The realization of flying screen on PC is a little complicated. You need to install a software first, and then perform image operation.
▲ Opening the software is a boot operation, so there is no need to worry about Xiaobai users.
▲ After the above operations are completed, the projector will be connected to the PC end, and the projector end and the PC end will display synchronously, with the same effect as the teaching projector.
Projection effect test
Solid color display
Due to limited shooting equipment and shooting environment, the actual projection effect will be better than the renderings we shot. Especially for pure color test, the actual effect will be more natural and accurate.
▲ The four solid colors R, G, B and Y are more natural, and the expressive force of yellow is slightly worse.
Document Presentation
▲ In the presentation of office documents, the display effect is clear with straight and clear lines, but there are still some gaps with professional commercial projectors.

Live shooting of high-definition film effects
▲ In the high-definition image playing live shot, the bright and dark pictures show good picture effect and good contrast, while in the pictures with rich content and color, the details in the picture can still be accurately captured.
summary
Huayi V5, as a projection device with small size and unique flying screen function, (the price of 2499, equipped with two 3D glasses) has obvious advantages over similar products on the market. The introduction of the flying screen can not only fully expand the video resources, but also serve as a teaching projection equipment for both civil and commercial purposes. Based on Android system, it is more intelligent and open, not only suitable for ordinary families, but also able to meet the needs of geeks. For ordinary family users, Huayi's video camera's image quality performance can meet the daily needs, and its shocking large screen viewing effect and 3D depth of field experience are also outstanding.
But in terms of details, Huayi V5 is not very outstanding. It requires an external remote control receiver, and the remote control operation is too fast, and the probability of jamming and other problems will undoubtedly reduce the user experience. However, the advantage of the products created by Internet thinking is to achieve rapid iteration and improve the use experience by constantly collecting user feedback.
The traditional TV not only needs to occupy more indoor space, but also the larger the size of the TV, the more expensive its price will be. When it reaches 70 inches, it needs five digits, which is difficult for ordinary users to accept. For users who like to experience large screens, the projector is a good choice.
