With the development of technology, micro-projectors have finally embraced the bright spring after undergoing numerous technological innovations. Not only did they have a great improvement in brightness performance, but they also carried smart systems, video, music, and mobile phones. Family entertainment and leisure functions such as playing games have all been added to them. The 100-inch giant screen shock and the easy-to-price price of 1,000 yuan have made smart micro-investment quickly become a popular rookie in the audio-visual field and has been sought after by fashion men and women.
Just in 2015, it was a year of concentrated explosion of projection brands. Giant screen, smart, and portable became the keywords of projection, and even the concept of non-screen television was introduced. The momentum was directed at the current tepid TV field. The current smart projectors on the market can be of various types, with different functions and dazzling choices. While increasing the selection opportunities, we also have to make choices. So how do you choose a high price projection that suits you? The author here for your brief analysis.
Purchase Notes
First of all, it is necessary to have a general understanding of such products before buying smart micro-investments, so as to avoid being pitted by unscrupulous merchants because they are not familiar with the products. Smart micro-projection refers to a projector equipped with a smart operating system and adding wireless WiFi Internet access. Combining the features of projectors and smart devices, the following points are the ones that you need to pay special attention to when purchasing:
1. Light source brightness
At present, most of the micro-projectors use LED light sources. Compared with traditional UHE and UHP bulbs, LED bulbs have a small heat output, low power consumption, and long life, but their brightness is lower than that of traditional light bulbs, which also contributes to the fact that currently there are few micro projections. There is more than 1000 ANSI lumens of brightness. However, for home projection, in a dark environment with good light shielding, an image brightness of 200 ANSI or more is acceptable, and an image brightness of 600 ANSI lumens or more can be achieved. Everyone needs to pay attention to the unit of brightness and the imaginary mark when buying micro-projections. Some merchants use the relatively large ISO standard for brightness labeling in order to cater to the consumer's psychology, such as intentionally marking the brightness of 450 ANSI lumens as 1500 lumens. More unfair business direct ambiguity, deceive consumers, these are all we need to be vigilant.
2. Resolution
Good image quality is based on higher resolution. If we want better projection images, then we must choose microprojections with higher physical resolution. Currently, most of the micro-projections on the market use DMD chips developed based on Texas Instruments and DLP digital light processing technology based on this chip. The maximum resolution supported by this technology is 1280×800 (720P), so for now, if It is absolutely false to have a manufacturer label a product with a resolution of 1080p or even 2k and 4k.
3. Contrast
Contrast refers to the ratio of black to white on the screen. In general, the greater the contrast, the clearer and more eye-catching the image, the brighter the colors, and the less contrasting, the entire picture will be gray. At present, most DLP projectors have a nominal contrast ratio of 1500:1 (full white/all black). Some major brands have reached the mainstream of micro-projection 5000:1, of course, the higher the projector the higher the price, we need to be psychologically prepared for purchase.
4. System performance
Smart projection is no longer just a device that acts as an image output. It has network connections and smart systems that support the installation and operation of App software. Therefore, the system's operating capability, stability, and compatibility are also considerations when purchasing smart projectors. of. The vast majority of current smart micro-projections are systems based on Android customization. Most mainstream brands use Mstar smart TV processors, but the number of audit architectures, GPUs, and memory sizes vary. In the end, however, for those who want to enjoy high-definition encoding 4K video and thrilling large-scale games, users need to refer to the merits of the performance when purchasing micro-projection.
In addition, the projected throw ratio and color processing technology (that is, the color effect of the screen) are also more important, but for most users, these are blind spots of awareness and generally do not care too much. In terms of functionality, users can also have many choices according to their needs, such as whether they can carry it, whether they have a business model, whether they are compatible with 4K, support 3D, etc., and with the integration of voice input and somatosensory manipulation, these functions are also multiple Or less affect the user's choice. In addition to avoiding fraud by merchants, it is the users who really need to face the problem of how to buy only if they are not expensive.
Purchase guide
Although smart micro-invested brands are numerous and complicated in style, they can be roughly divided into three categories: mini-compact, stylish portable, and high-end home. In addition to mini-micro-casting because of low prices, low technical requirements and mixed chords, the other two categories are relatively clear in the purchase, choose the basic range in the meters, cool music, nuts and other mainstream domestic brands. The author summarizes the corresponding intelligent micro-investments in the market, and then presents them to everyone.
Mini compact
Such projection heads are often only palm-size or mobile power similar to mobile phones, and the brightness is relatively low, generally not exceeding 100 ANSI lumens, and the projection size is only about 100 inches. This type of projection is mostly used for personal simple entertainment or one-on-one business, and the price is generally not more than 2,000 yuan. Such projections are due to low prices and low technical requirements. No-name and small-manufacturers produce most of them. The quality varies greatly. It is time for people to buy their eyes that need to be polished. I simply introduce two models for everyone.
1, Cool music as Q6 Elite Edition
Cool music as the Q6 elite version of the compact size, easy to carry, only 999 yuan price allows more people to taste the fun of projection, and built-in 5000mAh lithium battery, easy to travel and mobile office use. However, the corresponding brightness and resolution all belong to the low-end configuration, and the use of the environment requires a relatively high quality, and it is difficult to obtain a good image quality effect. At the same time Rockchip micro-core processor and 512M running memory make the machine's running ability limited.
2. Papa pocket cinema
Papa's pocket cinema is also a mini compact model. The projection parameters are not much different from those of Cool Music's Q6, but the battery capacity is slightly lacking. The 3300mAh estimate can also play a standard movie. However, in appearance, Papa is significantly more refined, stylish atmosphere, using a square structure, hold and hold. In addition, Papa uses a quad-core Cortex A9 processor and 1G of running memory, which has a slight advantage in system performance.
The author's comment: From the above two projection parameters we can be compact and portable is the biggest feature of the mini-products, but only 60 ANSI brightness and only WVGA-level resolution is really not enough. If there is no large-scale presence in the home, commercial use of ambient darkness is highly demanding and inconvenient. It's probably only suitable for personal entertainment or a little romance with the female ticket.
Fashion portable
Fashion portable intelligent projection has the right price, portable body, can also be used for business while satisfying home entertainment, so this type of micro-projection is the most popular type of smart projection products, but also businesses are most worried about of. Such projections are of a suitable size and can be easily carried in a bag. The brightness is generally around 250 ANSI lumens, the resolution is 720p, and the projection size is more than 100 inches, which can fully meet the daily viewing requirements. The performance is also very good, to meet the HD decoding and smooth running of large games. Built-in large-capacity battery is very convenient for both home and business. Here I've singled out several of the more popular products under a brief introduction:
1. Polar meters Z4Air: stylish, outstanding price
The Z4Air is a business-friendly portable mini-projector launched by Rami Technology. The product enclosure is made of high-quality Australian alumina, and the ultimate thickness of 23.5mm is classic. It can be said that the Z4 Air is produced in the same intelligent micro-projection product. The craftsmanship is first-rate, and the lens protection cover that is perfectly integrated with the power switch is also a highlight of the product. Built-in business model and entertainment mode, business home Xpress transformation; content, the pole rice and mango TV and Baidu music for strategic cooperation, can be described as rich in resources, while giving a value of 720 yuan for 24 months of mango VIP, Jingdong sells for only 2348 Yuan, the high cost performance, it is difficult to have the right person.
2. Nut P1: Dynamic appearance, super life
The first impression of the nut P1 is that it is dynamic and full of science and technology. It has a built-in 15600mAh high-capacity battery, and the endurance can be said to be the strongest in its class. The slightest regret is that the picture contrast is slightly lower, only 1000:1. The product Jingdong sells for 2,499 yuan. I believe this product has an irresistible charm for young people who love to be cool and love sports.
3. Cool music as X6: electric zoom, the ultimate ultra-thin
Cool music as the X6 standard full body aluminum-magnesium alloy structure, all-glass lens lenses, shape is also elegant. At the same time using ultra-thin light engine, body thickness of only 19.5mm, in the same product can be regarded as the thinnest. In terms of functionality, the Cool Music X6 also upgrades manual focusing to electric focusing, which makes it easier to operate.
In addition, the cool music as the original micro-channel remote control function is the first shot of intelligent micro-projection remote control. Cool music as X6 Jingdong price of 2699 yuan, micro-channel remote control, the ultimate ultra-thin it believes there will be less than the user likes.
4. God painting Z1: virtual touch, powerful performance
The divine painting Z1 is nothing special in appearance, even slightly rustic in the author's opinion, but it is very awesome in terms of performance, 2.0GHz quad-core CPU, 2GB running memory is relatively good in similar products. Some, at the same time, unique dual-lens design, support for auto focus and video virtual touch technology, to bring users more convenient and casual feel. However, this product is slightly ambiguous in the design of battery capacity, 8600mAh really less. High performance means high prices. The price of Jingdong at 2,999 yuan is the highest among similar products. Users with higher performance requirements can consider it.
The author's comment: The stylish portable intelligent projection has a qualitative improvement in brightness, the resolution of the picture is increased to 720p, and the picture quality of the 1080p or even 2K is compatible, and the viewing of the 3D movie is also realized. In addition, the improvement in performance is not small. Basically, it has the mid-range mobile phone's ability to run and meets the daily home entertainment needs. There is basically no big problem. At the same time, the built-in battery and portable body are also capable of being used in the business field, and their directionality is very flexible. At the same time, the business also develops the characteristics of its own products according to different user needs. The radish pickles have their own love. As for which one to choose, it depends on personal preferences.
High-end home type
Some reports pointed out that by 2020, the value of the hardware and derivative services created by the entire living room economy will reach RMB 1.1 trillion, and in addition to the television industry, new intelligent micro-investments will bear the brunt of these value-bearers. For this reason, the smart projection company is trying hard to create high-end home projectors that can be used in parallel with smart TVs. This kind of projection not only has the high-definition picture quality but also has outstanding performance. Creating a private cinema at home is no longer a dream.
1. Polar meters Z4X: video and audio, the price of sky
As a high-end new product released in 2015, Extreme Z4X unique vinyl record design, retro and stylish coexist. The fuselage is equipped with S8 Opto-mechanical engine and adopts dual-optical path design. The brightness is increased to 580 ANSI lumens, which is a major breakthrough in the field of micro-investment. In addition to outstanding picture quality, this micro-projection product is equipped with Harman Kardon's tailor-made sound system and WIFI speaker mode for 3D gesture recognition. In addition, the body's ingenious built-in hard disk drive with 2T capacity is the gospel of fans. The price of the product is only 2,538 yuan, and the high cost performance is unprecedented.
2. Nuts G1-CS: Fashionable, elegant and elegant
Nuts G1-CS home projection shape using CD metal texture design, a strong sense of science and technology, placed in the home atmosphere. In terms of brightness and audio and video, it has also been greatly improved. In particular, the GPU has been upgraded to six cores, and the picture quality has been improved. However, in addition to the superior design style, other aspects do not have much advantages compared to similar products. Jingdong currently sells for 2,699 yuan. It is not known whether such a high value for nuts will have more users to buy.
3. God painting Y1J: Convenient operation, where you want to go
God painting Y1K as a high-end model of home models using the nest style, compared to the portable model Z1 in addition to the strengthening of the machine and projection capabilities to the same category level, in other aspects does not seem to change much, even 8GB The flash memory did not see its improvement. The price of 3999 yuan is still very strong, but compared with the previous two projections, its previous performance advantage seems to have been no longer. However, the reason why this is still introduced because it still has certain advantages in autofocus and virtual touch technology, where to point where the fool-type operation is still very popular.
4. Polar meter Z4 Aurora: trapezoidal correction, force 3D
The Z4 Aurora Polaris is an upgraded version of the Z4X pole meter, the flagship king of the Kami home machine. Once again, it builds on the basis of the high price of the Z4X meter and introduces the trapezoidal correction function of only about 10,000 yuan. Aurora Aurora can present the best picture in a more complex and demanding environment. At the same time, the remote controller is upgraded again, not only supporting voice input but also supporting flying squirrels in the air and gravity sensing, and once again upgrading the user's operating experience. Although there is no major improvement in picture quality, it has added 2D to 3D capabilities to make 2D movies more exciting. The price is upgraded to 3,999 yuan, but the change is also real.
The author's comment: In the smart micro-projection of household products, we have seen a further increase in the shadow and tone, although the brightness of nearly 600ANSI lumens still can not enjoy the daytime to the TV, but have to say that home intelligence micro-projection brings us A more exciting night. Perhaps it's hard for me to point out who is better and who is better at portable projectors. However, in the high-end home micro-investment, I feel that the series of extreme meters is undoubtedly the most outstanding, especially the Z4X's high price is enough to conquer everyone's heart.
The figure above shows the data statistics of the company's major smart microchip manufacturers' product shipments in the first three quarters of 2015. It is not difficult to see from the figure that the shipments of the ultra-thin brand are the highest and higher. The sum of other brands is a matter of popularity.
Concluding remarks: At present, smart micro-investment products are just in the initial stage of the market, but for now, many brands and manufacturers want to share a share in this field. Facing so many brands and models, the author hopes that he will be able to purchase your favorite intelligent micro-projection with a few thousands of words that will help you choose your future.
