Exquisite and exquisite interface design Lightank D1 smart projection modeling is simple and elegant, warm porcelain white appearance can be well integrated with your indoor environment. The machine's compact size, the whole size of only 33.1cm × 30.4cm × 15.1cm, will not occupy too much space in the living room, the other weight is only 5.7kg, even if the strength of the female friends can easily move. 
The measured brightness satisfies the user's needs. The projector's data test mainly uses the ANSI standard developed by the American National Standards Association. This standard is also recognized as an authoritative standard in the industry. And consider the following aspects: maximum brightness, peak brightness, optimized brightness, and projector contrast color. Next, I will briefly explain a few technical terms for everyone: The first is the peak brightness, especially in the brightest mode, the highest brightness can be achieved at a single point, generally appear in the center point; maximum brightness, refers to the brightest mode The average brightness that can be achieved on the screen is higher than the reference value of this value; the optimized brightness, also known as ANSI brightness, is the average brightness of the 9 test points in the case that the projector just can distinguish eight gray scales. 
data analysis:
With regard to the brightness of the projector, there are three data in the table, namely the maximum brightness, the peak brightness, and the ANSI brightness. In simple terms, the maximum brightness is the average brightness of the screen in the brightest mode of the projector (brightness, contrast, and lamp mode are all adjusted to the maximum). From the results of our actual testing, the maximum brightness of the Lightank D1 smart projection is 777 lumens, which is a nominal 77.7%, which is still a certain gap from the best performance.
Peak brightness refers to the maximum value that can be reached at a certain point on the screen in the brightest mode. In general, peak brightness is best if it can approach 95% of the nominal value or even exceeds the nominal value. From the data actually tested, the peak brightness of the Lightank D1 smart projection is 873 lumens, which is a nominal 87.3%.
ANSI brightness refers to the ANSI test standard. As such, the ANSI brightness reference is more significant. From the actual test data, according to the ANSI test standard, Lightank D1 smart projection ANSI brightness reached 763ANSI lumens, and the maximum brightness difference is not large, it can be said to be outstanding, this brightness can also fully meet the daily needs of users .
Clear focus on the screen color reproduction High color testing has always been a very important part of the projector evaluation, in this link we mainly through the difference between the color test sample and real shot to understand the machine's color reproduction capabilities. So, as a projection product using 3LCD projection technology, is the performance of the Lightank D1 smart projection sufficiently bright? Here's the answer for you to unlock. 
Real shot images show excellent performance in detail. In fact, relative to the brightness, contrast and other parameters, color performance is a bad judgment, because everyone's favorite color style is not the same. So after seeing the color performance of Lightank D1 smart projection, the author has brought some real shots of the machine for everyone to help everyone understand more fully the color performance of this product. 
Smooth system operation and video resources The system interface of Lightank D1 smart projection system is simple and intuitive. The entire system is divided into four sections: film, music, games and applications. In the film and television system package ** Mango TV and Galaxy Kiwi fruit two major sources of content, built-in film and television resources are rich, while the music section has Baidu music constantly updated library resources. Overall, this machine can enrich the user's spare time. 
The measured performance is good Home users preferred Edit View:
The biggest feature of Lightank D1 smart projection is that its resolution is 10% more pixels than traditional 1920×1080 resolution products. During the evaluation, the author deliberately observed it at close range, and compared with other traditional 1080P projections. . After a detailed experience, the author can now tell you that the resolution of the Lightank D1 smart projection is indeed higher than that of the traditional 1080P projection. This should be very attractive to the user. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
Although the price of the recent 4K projection has dropped sharply, it is still expensive for many users, but the traditional 1080P projection can not meet the daily use needs. The Lightank D1 smart projection that we want to evaluate today brings us In the compromise, the resolution of this product is 1920×1200, which is more clear than the traditional 1920×1080 projection, and the price has not changed. How about its actual performance? Let's take a look with me. The Lightank D1 smart projection has a resolution of 1920×1200, which means that the user will get a sharper, larger picture. In addition, this machine also has a 1.2x optical zoom function, which can adjust the screen size while keeping the position of the machine unchanged. Compared with the traditional digital zoom, the optical zoom will not lose pixels and will not affect the picture quality. Give users a more outstanding viewing experience. The above figure is the objective test result of Lightank D1 smart projection. It is believed that you already have a general understanding of this machine through it. However, objective data such as color, system, etc. is not reflected, so I still recommend that you look at the complete department. Well, here we go into the complete evaluation of Lightank D1 smart projection. Behind the Lightank D1 smart projection is a rich interface such as USB3.0, HDMI, and LAN that allows users to connect multiple devices at the same time. In addition, the Lightank D1 smart projection design has a manual focus ring, allowing the user to quickly adjust the focus of the picture, making it easy to use. The measured brightness of the Lightank D1 smart projection is 763 lumens, and this brightness performance is considered acceptable by the author. In addition, the color of the picture projected by the camera is good, but the overall picture color is cold. Since the author personally likes the cool color system, I personally appreciate the color performance of the Lightank D1 smart projection. The author tested a lot of smart projections, but in the smart system, the music was placed in a section of the product. In the author's impression, the Lightank D1 was still the first one. After opening the music, the author found that the music resources are very rich, as a music lover. , Lightank D1 once again brought me a surprise. After work, a person used it to listen to music in the evaluation room to relax, have to say that it feels very good. In general, the author believes that the Lightank D1 smart projection will surely become a good companion for your home.
Clearer than 1080P Lightank D1 Projection Evaluation
Lightank D1 smart projection adopts 3LCD imaging technology. As we all know, 3LCD technology has more advantages in terms of color. Therefore, Lightank D1 projects more brilliant colors without whitening and rainbow phenomenon. The transition between different colors is also more smooth and stable. . In addition, the Lightank D1 smart projection uses a new LED light source, which has a lifetime of up to 30,000 hours, which means that if you use 8 hours per day, you can use it for 10 years. Can be said to be a purchase, the light source for life-long maintenance-free. Clearer than 1080P Lightank D1 Projection Evaluation
