A few meters of white wall turned into a hundred inch screenless TV, no rice screen TV H1S experience

As a traditional projector user has been plagued by body heat and fan noise. Since Wang Han began to pay attention to domestically-made non-screen TVs, he has started to pay attention to the Mi-H1. What is the experience of a projector called a non-screen TV? Is it really possible to replace a traditional projector to achieve a simple home theater and bring a large screen shock? A throbbing heart has been driving my desire, so in the H1S debut, decided to get a try.
Polar Rice H1S is an upgraded version of H1, so what's the difference between H1S and the previous H1? From the packaging, the appearance is basically the same, a drawer is covered, and cables and remote controls are placed in the paper tray at a glance. Take out the host, well, still the same appearance, the same taste. In terms of volume, it is smaller than traditional projectors, and it is lighter in weight, only 2.1KG.

Occasionally moving is not very hard. The body of the aluminum alloy shell material texture is very good, unfortunately H1 on the standard remote control of aluminum alloy shell into a black plastic material, which contains 2 7th battery, I used to use the millet remote control I have to Adapt to its thickness. The upper left corner is the sign of Harman Kardon's commissioning. The right side of the logo is a camera, H1S autofocus depends on it, this is the new features added on the H1S, very convenient. The upper right corner is the lens, the protective cover is manually opened, and the protective cover is also the switch button. The lenses are all made of more wear-resistant glass lenses. However, it is still not recommended to wipe, and the glass will be scratched!

At the top of the H1S is the operating area. You can increase or decrease the volume by sliding the top volume bar. It's inconvenient to say another thing. It's still pretty to look good. There are also playback operation keys and Bluetooth keys. The bottom of the H1S is equipped with a bass passive diaphragm, which is the guarantee of bass power. The interface on the back is still quite full. Although there is no common VGA interface on the projector, it is certainly enough.

Install the adapter plate, install it on a tripod, plug in the power or familiar taste. Pushing the lens cover off will turn it on, which is very scientific from the point of view of convenience and use. This generation has the help of the autofocus camera, you don't need to use the remote controller to tune slowly like H1, and the autofocus finishes!

H1S was placed in the middle of the living room and I was facing the white wall. It was less than 4 meters away. The width of the projection screen is 2.7 meters, which is equal to about 120 inches. Of course, there may be some external factors in the measurement process, which are different from the ratio given by the official, but they do not affect the actual experience. Although it's possible to shoot a 300-inch banner on a mega-advertisement, it is recommended that it should be between 100-120 inches, because first you have a living room that is as big as a movie theater. The flux projected by the second projector is constant, and the larger the screen, the smaller the light energy per unit area and the lower the brightness. The official proposal is to use brackets to place the brackets. The brackets are sold on the official website, but there is no provision for this evaluation.

Fortunately, the H1S body is lighter, buy a hundred yuan camera tripod can also make do, with the tripod head to adjust the angle of the fuselage than to facilitate the use of trapezoidal correction.

It has to be said that the sharpness increase that the resolution of the Hitachi 720P projector that I used before increased to 1080P is quite obvious. The brightness of the 1100Ansi is still good for the interior of a light curtain, and Polarite H1S supports contrast enhancement.

The H1S speakers should be excellent in projectors. Since it is the formation of a home theater, there are conditions to buy a set of 5.1-channel surround it.

Resources include mango and iQiyi's blessings. The video resources are quite complete. Members can enjoy more exclusive content. Do not want to buy members can also install third-party applications, the fuselage is not a USB socket, dozens of G Blu-ray original copy to the mobile hard disk into the broadcast. Mac and iPhone can be directly on the screen with the projector through AirPlay, the operation is very simple. I personally prefer to watch online videos in this way, and I can skip super-long advertisements to find movies quickly.

To sum up, the non-screen TV provides an overall home theater solution compared to the traditional projection. It is easy to install, does not need to configure audio, operates smart humanity, and makes content acquisition more convenient. So that ordinary users can also experience large-screen audio and video, is no longer exclusive to professional users.

Mercury Slip Ring

A slip ring is an electromechanical device that allows electricity and data to pass through a rotating assembly. A mercury slip ring uses liquid mercury as the electrically conductive element inside the rotating assembly, as opposed to traditional carbon brushes. Mercury is a better conductor of electricity than carbon, and it also has a very low contact resistance. This makes it an ideal choice for applications that require high-speed data transmission or where reliability is critical. Mercury slip rings are used in a variety of industries, including medical technology, aerospace, and defense.


Why do we choose a mercury slip ring?

A slip ring is an electromechanical device that allows electrical current to pass between rotating objects. Slip rings are often used in applications where a cable or connector would otherwise twist and tangle as the object rotates. There are many different types of slip rings, but one of the most common is the mercury slip ring. Mercury slip rings offer several advantages over other types of slip rings, including high reliability, low maintenance, and long life. Here are three reasons why we choose a mercury slip ring:


1. Reliability: Mercury is an extremely reliable material, and mercury slip rings are among the most reliable types of slip rings available. Mercury has a very low failure rate, and it is not affected by changes in temperature or humidity. This makes mercury slip rings ideal for critical applications where reliability is essential.


2. Low Maintenance: Mercury slip rings require very little maintenance. Because mercury is a very inert substance, it does not corrode or generate any corrosive gases that would affect its reliability. Mercury slip rings do not require any lubrication, and they can operate in a wide range of temperatures and environments.


3. Economical Mercury slip rings have a lifetime cost advantage over other types of slip rings as well. Generally speaking, mercury slip rings are approximately 25% more expensive per kilowatt than other types of slip rings. However, because they require less maintenance and have a greater degree of reliability than other types of slip rings, they will save you money over the lifetime of your equipment.
