At the 2017 MWC Shanghai Exhibition, Qingcheng officially released its high-end series VOGA V laser projection mobile phones, hoping to break the conventional interaction limitations through laser projection and give people a new infinite horizon experience. Now this distinctive VOGA V has come to the studio to see how many breakthroughs it can bring with laser projection.

Exquisite appearance

As a high-end series of Qingcheng, Qingcheng VOGA V is obviously different from ordinary machines in terms of outer packaging. The main color of black and the square packaging all indicate its high-end positioning.

The entire outer package is very simple. In addition to the rendered image of the machine and the relevant slogan, only the label on the back lists the relevant parameters of the cyan VOGA V in detail.

Open it and you can see the teal VOGA V lying quietly inside. The bright orange is used in the inner layer of the package, showing a trace of vitality in calm.

The accessories are very rich. In addition to the standard instructions, pins, data cables and chargers, Qingcheng also has a transparent protective case, headphones and a small bracket for supporting the projection.

The front panel of the teal VOGA V is black, which can almost be perfectly integrated with the body when the screen is turned off, bringing good visual effects.

The back is a common three segment design. The injection molding antenna on the metal body to ensure the signal acts as a "dividing line", and the CNC trimming on the side is quite textured.

Since the projection module and the camera are placed on the top, the camera part inevitably protrudes. However, in order to better decorate this part, Qingcheng imitated the design of high-quality wristwatch using tourbillon streamer. The lenses made with 10 layers of technology are very eye-catching.

The buttons on the side are not lazy. The power button has been specially textured to better distinguish it from the volume button. The metal material also reflects the whole metal body.

Projection module is arranged on the top, and Qingcheng is very considerate with protective dust cover, which can provide better protection when projection is not used.

Teal VOGA V provides a wide range of colors. We got two kinds of colors: obsidian black and moonlight blue. The integration of obsidian black is stronger, while moonlight blue is more exuberant. Both of them are excellent in terms of workmanship and seams, and the metal texture is also outstanding. And the laser projection is integrated in a slightly larger volume than ordinary smart phones, which is not a bad design.

Systems designed for projection

Qingcheng VOGA V is equipped with a VOGA UI that is deeply customized based on Android 7.0. The overall style is similar to that of most domestic brands' customized ROMs. The secondary menu is canceled, and a shortcut menu is arranged on the left side of the main screen. The smoothness is basically satisfactory, and 4G memory is fully enough. But the VOGA UI is also very different. It has customization options for projection services everywhere.

For example, its main screen is equipped with a projection switch, which can quickly open documents, pictures, videos and other content for projection, which is very convenient; Even if it is not on the main screen, it does not matter. The drop down notice bar is integrated with the projection switch, and the projection can be turned on with one button on any interface; At the same time, you can also perform projection operations in pictures and documents in one step, and there will also be projection assistants to operate during projection, which can be said to cover all aspects.

Moreover, the projection of Qingcheng VOGA V is not only simple, its system supports the connection with other mobile phones, and directly projects the interface of another mobile phone to achieve wireless same screen; Similarly, the system also supports connecting other mobile phones as remote control devices, and wireless control is optional; In addition to operating on the screen of Qingcheng VOGA V during projection, the system also supports operating when the screen is turned off, officially named "black screen control".

It can be said that the system of Qingcheng VOGA V is not very different from that of other manufacturers in terms of functionality, but every option customized for projection service can make you clearly realize that this is a smart phone capable of projection, which makes people eager to try. In addition, many adaptations have been made to meet the various needs of consumers, including ordinary projection, projection sharing, and even black screen control. Every time you use the projection of Qingcheng VOGA V, you can feel the intention of the manufacturer.

Screen 1+1

The teal VOGA V is equipped with a 5.5 inch 1080P full fit screen on the body. The default color temperature is 8390K, which conforms to the taste of Asians who are cold in tuning. The maximum manual brightness obtained from the test is 435 nits, covering 94.7% of sRGB color gamut, and the average DeltaE is 4.3. The actual appearance is similar to the test. The overall feeling is cold and the permeability is good. The visibility in the sun is OK and the quality is good.

However, Qingcheng VOGA V has a better "screen": equipped with MEMS laser imaging projection. According to the official parameters, the maximum projection size is 200 inches, and the resolution has reached the 720P HD standard. Using the MEMS laser projection technology, firstly, the volume of the projection module is greatly reduced, and compared with the previous projection mobile phones, the Qingcheng VOGA V is more compact; Secondly, it does not need to focus like the traditional projector. It has a trapezoidal correction function, which can display normally even if it is tilted; At the same time, the projection of MEMS has higher contrast (5000:1) and wider color gamut (150% NTSC) than DLP technology.

Although limited by the resolution, the teal VOGA V performs well on the test chart. The details can meet the projection needs of business people. The color gamut is excellent, the visual angle is also good, the trapezoid correction is also powerful, and the level restoration is much better than that of ordinary projection phones.

In the field test, the projection effect of Qingcheng VOGA V is much better than what the author expected, and it has been greatly improved compared with the previous projection mobile phones. Of course, due to the size and light source, don't expect perfection in strong light. Just a little control of the light at the projection, the Qingcheng VOGA V can immediately become a portable projector as shown in the picture, and the PPT speech can start anytime and anywhere. Whether in the coffee shop or in the restaurant, business exhibition is so simple that it helps the work take off.

In a dark environment, the projection performance of the Qingcheng VOGA V will be better, and it can also support the wireless connection of the mobile phone as a remote control. You can hardly enjoy the glory of playing king with the projection. The Qingcheng VOGA V can also cope with the occasion of multi player gatherings. It has built-in games that multiple players can play at the same time, so you don't have to worry about the small screen of your mobile phone to play with friends.

Back at home, close the curtains and open the video of Qingcheng VOGA V to project it. Then the mobile home theater was born. It is so simple to share happiness with family and friends. With projection sharing, Qingcheng VOGA V can instantly become a professional projector, and all kinds of resources on other mobile phones can be shared through it, which perfectly explains that solo music is not as good as public music.

It is worth mentioning that because the MEMS technology used by Qingcheng VOGA V has unique advantages in color gamut, it is more excellent in projecting videos or pictures with bright colors and obvious contrast, which is pleasing to the eye.

Duty camera

In terms of photography, Qingcheng VOGA V has a front camera of 8 million and a rear camera of 13 million, which belongs to the current mainstream level. In terms of photographing function, Qingcheng VOGA V also has panoramic, professional and night view modes in addition to the automatic mode. The video also provides the option of slow motion, which basically covers the scenes of daily use. If you want to have special filters or weird effects, you can install a third-party app to achieve it. Focusing is relatively fast, and the imaging is basically without delay. The photo taking experience can match the positioning of Qingcheng VOGA V.

In terms of the performance of the actual proof, the white balance, details and tolerance of the Qingcheng VOGA V are remarkable, but after all, it is the positioning of the main projection, so photography is naturally not the top level. Rest assured that Qingcheng VOGA V is competent for most of the daily use scenarios, and the need for business people to shoot documents is no problem.

Excellent endurance

In order to ensure the duration of projection, Qingcheng VOGA V is specially equipped with a large 4000mAh battery, and its endurance performance is quite expected. In our routine endurance test, the last remaining 79% of the power of the Qingcheng VOGA V is enough for one day's use. During projection, the screen and projection automatically adjust the brightness, which consumes 24% of the power in half an hour. That is to say, the fully charged Qingcheng VOGA V meets the requirements of two hour projection without pressure. With the power saving adjustment, the built-in screen will be turned off, and the projection time can be further extended. Compared with the previous projection mobile phones, the performance is significantly improved.

summary

Qingcheng VOGA V performs well in all aspects. Compared with previous projection predecessors, it is more excellent in both volume and projection ability, and can meet the needs of different scenes. Moreover, Qingcheng is also very accurate in its positioning. In the face of business people who need mobile projection and some large screen entertainment users, Qingcheng VOGA V can cope with all kinds of scenes such as mobile office, multi person gathering, and ready cinema. The improvement of endurance also makes it more confident.

It is totally different from other manufacturers in competing for a larger high-end market. Qingcheng is aimed at subdividing just needed users, making it easier to find a breakthrough. Qingcheng's VOGA V is also strong. For users who have requirements for mobile projection, it is worth being included in the alternative list.
