From the appearance of early projectors to various current smart projectors, they have gradually spread from commercial applications to civilian applications. More and more brands have become smaller, smaller and more functional, and prices have become more and more affordable. Accept, but don't buy products below 1,000 yuan, no matter in terms of display effect or service life.
Then another kind of projected product form began to appear, that is, projection TV or no screen TV. In fact, plainly is a combination of projection + set-top box, which is like your usual use of set-top box + projection gameplay, the screen is bigger, and also their own Will choose to add a speaker, audition will be better.
In the projection TV of the current market, PIQS Divine Painting is somewhat different. It is an intelligent micro-projection product introduced by Shenhua Technology (Shenzhen) Co., Ltd. in June 2016. It is said that it is an alternative because one is too small, it is really a micro-projection, a little bigger with the iPhone6s, and the size of the strip-shaped purse is similar to that of a married woman. Although the orientation of the product is oriented to the majority of college students, this portable feature undoubtedly brings convenience for travel and business trips.
In addition to the small size, there is also a main function of the gods and paintings is the AR function, support AR experience, that is, human-computer virtual interactive experience.
Hardware Configuration
The current 1G memory + 8G storage mix, in the set-top box configuration is very common, even 8G storage space than some domestic smart TV 4G storage products are good and practical. Cortex A5 quad-core CPU with Mali 450 MP6's design, multi-task processing is not a problem, to see 4K, 2K video is not a big problem, but the decoding of the support to be verified.
The god of painting uses RGB LED light source, DLP display technology, brightness is 300 lumens, not very high, it is necessary to pull the curtains during the day. The dynamic contrast ratio reaches 1000:1. This parameter will only be experienced in actual viewing. It is not that the bigger the value is, the better it is. It can be used as a reference but not to be influenced by numbers. After all, the situation of the virtual target in the projection market is still prevalent.
The products are those things
advantage
1. exquisite workmanship, excellent material design, small size and portable
2. Mainstream common hardware configuration, Cortex A5 quad-core CPU + Mali 450 MP6 design, with 1G RAM + 8G storage, to meet the daily needs

Need to pay attention
1. Lumen is 300, brightness is normal, but in the same price, the same volume of smart projection products is the mainstream
2. TF card supports up to 32G
3. HDMI as a monitor output, compared to pick the device, some computers or set-top boxes can be identified but can not normally display the content. According to the feedback from the manufacturers, an agreement has been reached with the authorizing party and there is no such issue in the follow-up
4.500G or higher mobile hard disk will not be recognized properly due to insufficient power supply, and it needs to be equipped with an independently powered USB HUB.
product description
The PIQS charm painting is relatively complete in terms of accessories, in addition to the necessary power adapter, Micro USB power cord, magic pen (Bluetooth gravity sensor remote control) and a host, but also provides an HDMI video cable, a The main body storage bag and the special bracket used for the use of the gods.
The storage bag is made of smooth silk material but thicker in material. It won't scratch the body of Xiaomei. The inside and outside workmanship is very fine. There is no problem of thread run or pin thread running. HDMI and USB cables are thicker, and they are much better than some of the set-top boxes, guaranteeing the stability of data and charging transmission.
The bracket is divided into two parts, not a plastic material, but a slightly heavy alloy material, the assembly is more convenient, and the insertion can adjust the angle of the movable part. The base adopts the design of integrated aluminum alloy architecture style. The surface of the bracket adopts anodized sandblasting technology and looks more beautiful.
To fully understand God painting. Xiaomei adopts Champagne gold color, and the upper shell adopts nano UV panel and optical coating technology, which makes it easy to think of the 2.5D glass design used in some current mobile phones. It is used to prevent scratches, anti-fingerprint and anti-stain, etc., but in terms of heat dissipation performance. There will be some influence. Only the aluminum-magnesium alloy is used in the middle frame, which keeps the weight of the body at about 235g. In addition, the 5700mAh rechargeable lithium battery is also built into the device.
The front adopts a dual lens design for fast autofocus. On the left side is the projection lens with the German OSRAM light source. The surface has been coated with 10 pieces of high-precision optical glass lens to ensure the brightness uniformity and color truth, but no lens cap is designed to make people feel less protection. , so I hope that the follow-up products can be added to the lens cap. The right lens is an interactive lens. From the actual experience, the interaction includes AR and remote control. In simple terms, the main lens is responsible for the projection screen, the auxiliary lens is responsible for monitoring the screen, with the realization of automatic focusing function.
As for the middle of the filter design, although it looks not very beautiful, but the role is very important, is one of the body's heat vent.
There are two tuyere in total, except for the one in front of the front and the one on the right, which can form a double channel for heat dissipation to ensure that the equipment will continue to work without hot.
The main interfaces of the painting are focused on the left, including an HDMI interface, a TF card interface, a USB2.0 interface, and a 5V DC interface. The small round hole on the side is not a reset hole but a power indicator. TF card is only supported to 32G, not 128G; USB interface supports 1TB of external storage device, but unfortunately it is not USB3.0. It will have some influence when playing large-size video. The design of the power supply and charging switch is somewhat peculiar. It adopts a push-pull design. It pushes for three seconds to the left, and pushes it to the left or pushes the 3S to turn it off when it is turned on. As for the charging status, it is toggled to the right when the power is turned on. Charging while playing, dialing in the off state and charging in the fast charge is fast, which is necessary for the 5700mAh battery.
The design of the rear fuselage is a speaker, the second is the source receiver, and the third is a 3.5mm headphone jack. This kind of design is mainly aimed at the scene such as a bed couch when the daily use of the bracket is used, and the device will be placed in front of the user. So if you're like me, often lying on the bed with a visual ceiling may feel inconvenient to plug in the headset. Speakers are high-fidelity independent speakers, from the BMW car audio brand, then the sound quality is worth the wait.
The bottom is also made of alloy material, beautiful, but easy to be scratched, why not use the nano-UV panel to deal with the front. At the bottom, there are only five silicone mats with a very small area, but the problem of slipping is not significant. The round hole at the bottom near the center is used for fixing with a bracket, and some self-timer bars can also be used together.
The remote control works well, all using nano-UV panel material, is also a built-in rechargeable lithium battery, charging port designed bottom. The transmitter on the top has a large area, and the key design is simple. The number is close to the common set-top box keys. Why is it necessary to design the power button and volume button on the left and right sides, respectively? This is not a mobile phone. It is inconvenient to operate with one hand. It is recommended that all designs be directly on the front.
Enter the actual experience stage below.
product experience
Here are some aspects of the auto focus effect and the screen size, pen experience, audio and video experience, VR experience, performance running experience in several aspects.
Auto focus effect
Auto focus function, but there is no trapezoidal correction function. Focusing can be done within 2 seconds, but it is related to the projection screen, which is the focal length. Through the actual measurement in the 0.8M-1.8M can be completed normally 2 seconds, which is also their own commonly used projection distance, the focus is more clear, do not need to manually adjust. If it exceeds 1.8M, there is auto focus due to the increase of the screen, but the resolution is somewhat poor. The device automatically adjusts the focus each time the distance and angle are displayed. The following figure shows that the time displayed in the screenshot will be greater than 2 seconds due to the reason that the disappearance of the font and the delay in manual capture and success.
The relationship between the screen size and the projection distance is as follows, you can choose to adjust according to their own use of the environment, their own bed to see the basic forecast of the ceiling is about 70-75 inches.
Screen size (inch) 25 35 40 60 180 Projection distance (m) 0.8 1.1 1.2 1.9 2.8 3.7 4.75.6
System and introduction
Xiao Mei Mei uses the PIQS UI2.0 system based on Android 4.4.2. The UI and the interface adopt a common flat design rather than the common waterfall flow style. The classification is clear and clear, giving the user more convenient interface control. Experience.
The user can see the tutorial: God Painting Mei Mei M1 installation method Install the sofa butler to expand third-party applications.
However, this is a common practice for lazy people nowadays. If you don't want to install third-party software, you can directly enter the system settings and open the test mode to open the test mode. That is, enter the settings and select About Projection TV, then select the version number and click on the version number more than 5 times to open Developer Mode. Under "Developer mode", check the "USB debugging" and "Test mode", and the installation files in the U disk can be seen.
Because Mei Mei's lumens are only 300, if you want to get a more realistic picture, darker lighting is necessary, and all-black interiors work best. The direct method of testing the screen display effect is to use the mobile phone to scan the two-dimensional code in the projection screen. When the definition is good, the iPhone6s and the Samsung S5 can identify the two-dimensional code within 3 seconds and correctly parse it.
Let's take a look at the photos taken during video playback. However, if you turn on a small desk lamp, there will be disturbances in the display effect and the colors will become lighter. So if you want to get better visual effects, watch it in the dark room. The following figure shows the actual shooting proofs and video shots under the default setting. The shooting camera is in the D3300 manual mode. The picture is not retouched, but it is more difficult to restore the effect shown in the figure. The effect of Xiaomei's actual display is that the brightness is not as high as the original video, but the color saturation is higher, whether it is grass, blue sky, flowers or clothes.
For teaching or office, the projected display effect of the document is acceptable. Whether Pdf or documents such as word, excel, and PPT, the display effect is also clearer. So it is possible to use it for teaching or meeting. (Image is Gif)
The magic pen is actually a matching remote control. It supports the gravity sensing function and supports virtual touch. This is the reason why you don't see which direction keys of the traditional remote control. It can be said that it is a kind of great innovation. After all, the experience it brings is also totally different.
Since it is a pen, it should be arbitrarily drawn, and the fact is true. First of all, for the cursor, which is the small hand of the figure below, it can be moved by shaking the stylus, eliminating the traditional remote controller frequently pressing the arrow keys to move Cursor trouble, sensitivity is relatively high, cursor movement corresponding to the movement of the stylus slightly delayed but not obvious, but also hold down the OK key with the left and right gestures to slide to achieve page switching, similar to the left mouse button function.
An important application scenario of this kind of simulated touch click is games, especially those games with touch screens, such as ski adventures, which can directly simulate the operation of tapping the screen to play the game.
Video playback and external memory card support
From the detection of video formats, the situation is not optimistic. Although there are no unsupported formats, there are seven formats that are not completely supported, and they contain frequently downloaded MP4 and MKV formats, which means that there will be video playback. Unable to play.
In the AR experience, Divine Image uses image recognition, 3D reconstruction, and automatic 3D mapping. It uses dual cameras to recognize objects in front of the camera in real time, and then uses CPU processing to map preset content to objects. In order to display the AR effect. However, only palms can be experienced at present, and other objects cannot be scanned and identified. (Image shows GiF)
Bluetooth connection is stable
The Bluetooth version is relatively high, using BT4.1. For Bluetooth speakers, Bluetooth controllers, Bluetooth headsets and other devices, there is no problem with the connection. However, in order to ensure the smoothness of the system, Bluetooth devices should not be connected too much at the same time.
Explain why you are passionate about doing Bluetooth compatibility testing, because you have encountered some problems with Bluetooth products that cannot be properly connected and can be successfully connected but can not be used, all of which are related to the hardware and software of the product. It is necessary to verify whether it is Bluetooth 4.1, 4.0 or Bluetooth 3.0.
For the performance section, one point to emphasize is that the score is only a reference. It is more meaningful to compare with other similar products under the same hardware configuration. For example, the 18533 score obtained with the security Bunny below may be a fraction compared to the high-end flagship mobile phone, but ranking in TV boxes and smart TVs? You can refer to your box or TV running situation to compare. However, a realistic situation also exists. It is a high performance and low experience. Running points are really high, but the user experience is not good.
3DMark's score reached 2151, but what I would like to say is that the CPU can run at full capacity during the test. There is no surprise that there is no slight fluctuation. (here Gif)
Here, the cat's smart socket intercepts the power situation during the use of Xiaomei. Figure 1 shows the real-time power when the computer is turned on, which is less than 12W. When it starts playing online video, it rises to 12W, and it floats within 12W. When connected to a 1TB hard disk to play local video, it rose to 13W. In terms of power, it is not great.
Regardless of whether you like to think of Xiao Mei Mei as a projection TV or as a fitting device for set-top boxes and projectors, the innovativeness of Xiao Meimei is not only small in size, but also the design that breaks the traditional remote control. The remote control is not a magic pen. The design of the arrow keys, but shaking the cursor to achieve the movement of the cursor, the movement is more convenient and quick, the design of the virtual touch screen to play touch screen games on the projection became a reality. The function of VR virtual reality is worth experiencing, but the function and gameplay need to be further improved.
It is a fact that there is no advantage in brightness and resolution compared with a few thousand yuan for a projection projector TV. However, similar products with similar prices are more contrastive. Compared with other similar thousand-thousand-smart projection TVs on the market, whether it is design, function, or display effect, the cost-effectiveness of the DIY AR projection TV is more outstanding. .
As a portable intelligent micro-projection TV or non-screen TV, limited and volume size, Xiao Mei Mei hardware configuration is relatively moderate, 300 lumens is not high, but the overall performance can deal with drama, office meetings, teaching, etc. The use of aspects. At the same time, it is also beautiful and stylish and small volume design, making the gods painted with a very high portability, will not occupy too much space. With the built-in 5700mAh lithium battery and MicroUSB charging interface, you can use mobile power to meet short-distance entertainment.
