On April 25th, 2017, Kizemi held a press conference and officially released a number of non-screen TVs such as the H1S and Z5. However, what attracts the most attention is a product targeted at children – the ima children’s screenless TV.
Why is this product more interesting?
Because this is the first product targeted at children in the screenless TV market, filling a market gap that many people have not yet realized.
If there are children or parents around the reader, they will fully understand that most children now have a bad habit, that is, they are always on the screen.
Whether it is a TV, a mobile phone or a tablet, children always need a piece of screen to see the animation play the game. Although everyone knows that watching the screen is not good for the eyes, since the bear children can be quiet for a while, many people have closed their eyes and closed their eyes.
This has always been a kind of pain point, but there were no products on the market for this issue before, and imea children without screen TV came from it.
Can its performance meet the needs of bear children? Can they protect their eyes from harm?
Second, popular science: You have no screen TV. You want to know all this.
“No Screen TV†is a new product category that was launched in 2014. It was born out of a projector. As a newborn, many people may have heard of it, but most people do not understand it.
And because of the inextricable link with the projector, most people are confused about some of their terms and parameters.
For example, "Can I buy a projector as a screenless TV?", "Is there a TV without a screen TV?", "How is 1200 lumens lower than 400 ANSI lumens?", "What is the ghost of DLP and 3LCD?" and many more.
The question has come, so the answer is not far away.
1. Is a screenless TV a projector?
Everyone is familiar with the projector, and the application scenario is very extensive. Everyone should see a lot in the classroom and the company. I will not repeat them here.
The principle of non-screen TV and projector is the same. They are devices that project images onto walls or curtains. As for the biggest difference between the two, the author thinks it should be TV content.
The projector is generally just a single device and does not provide or contain video image content. Unlike a screenless TV, not only can it be placed on the screen, but it also often contains an operating system (usually Android), and many video and live broadcasts are built-in. Resources.
In other words, a non-screen TV is like a TV box with a projection function. If you buy a projector separately, it cannot be used as a non-screen TV. Therefore, after careful investigation, a non-screen TV should belong to household appliances.
2. What is the difference between non-screen TVs and TVs?
1 Advantages of No Screen TV Compared to Ordinary TV:
- Lightweight and portable: Obviously, no screen TV is very lightweight because it does not require an oversized screen to display the content.
The length and width of a non-screen TV is generally no more than half a meter, and the weight does not exceed 10Kg. It can display hundreds of inches of content. The 100-inch traditional TV should be at least 2 meters and weigh more than 100Kg.
- Adjust freely: No screen TV can change the screen size with the change of distance, even from 30 inches to 300 inches, suitable for various areas of the wall curtain.
And how many inches do you buy for television?
Eye protection: This is even simpler. No screen TV is placed on the screen and reflected in people's eyes. It is a diffuse reflection process. The eyes of the viewer will not be very exciting.
The average television is how much light, how much light the human eye received.
2 The disadvantages of non-screen TVs compared to ordinary TVs:
- Insufficient brightness: Because screenless TVs rely on diffuse reflection to provide pictures, their brightness is often inferior to that of televisions and is easily affected by ambient light. Low-brightness non-screen TVs often have no way to use them during the day, but with With advancements in technology, there are now many non-screen TVs with brightness exceeding 1000 ANSI lumens.
- Quality problem: When the TV has entered the 4K and 8K resolutions, the mainstream non-screen TV is still 1080P.
3. What is the difference between ANSI lumens and lumens?
When measuring projection products, there has always been a very important parameter - lumens.
Lumen (abbreviated to lm) is a measure of luminous flux. The specific meaning is that light energy passes through a certain area in unit time. The greater the luminous flux of the light source, the more light it emits.
For example, a 40-watt ordinary incandescent light bulb has a luminous efficiency of about 10 lumens per watt, so it can emit about 400 lumens of light.
People familiar with projectors know that brightness is one of their most important parameters. How many lumens have been used has always been their focus. However, in the last two years, a new lumen unit has emerged. This is ANSI lumens.
ANSI lumens are the lumens of the American National Standards Institute. Previously, lumens commonly used in the market were the lumens of ISO (International Organization for Standardization).
Because the two test methods are different, in general, 1 ANSI lumens = 4 ISO lumens, which is why many projectors want to write two zeroes instead of what the lumen unit is.
For example, a projector with a top-ranked sales volume is marked with 900 lumens, but after consulting with customer service, the actual parameter obtained is 50 ANSI lumens.
4, DLP display technology
Imea children's non-screen TV uses DLP display technology, which is one of the mainstream projection technology in projection products, in addition there are 3LCD (mainly Japanese manufacturers) and LCOS projection technology on the market.
Here we mainly talk about the working principle of DLP, projector has always had the ultimate problem, and their own color LCD screen can be different, we all know that the projector will certainly have a strong white light source to project, DLP is how to light The white light becomes a variety of colors?
Before answering, we first clarify two concepts:
First, DLP is a projection technology invented and commercialized by Texas Instruments. It is called "Digital Light Processing" or digital optical processing technology.
The second is that DLP has a core component DMD (Digital Micromirror Device), or "Data Micromirror Device."
Well, the DLP has turned white into color, using two magical props, one for the color wheel and one for the DMD chip.
The color wheel is a transparent disc coated with 3-8 colors (having at least three primary colors of RGB), which is the first item that the white light passes through.
Obviously, whether it is white light or not, as long as it is filtered by the color wheel, it will show one of the three primary colors of RGB, and the color wheel is constantly rotating during operation (speed is generally more than 200 rpm).
So through the color wheel, the projector now has an uninterrupted RGB trichromatic light source. How do these three primary colors form tens of millions of other different colors?
This step was passed on to the DMD chip. The light filtered by the color wheel in the projector was focused on the DMD chip through the lens.
Before explaining it, everybody needs to pay attention to, DMD chip is not a chip in common sense, in fact, it is a very magic optical chip.
How amazing is it?
DMD chip is composed of tens or hundreds of thousands of small mirrors!
The small mirrors on the DMD chip can adjust the angle according to the instructions to determine whether this light shines onto the body or not.
And tens of thousands of small mirrors can be adjusted according to the instructions of the three primary colors who are reflected more and who are reflected less.
The speed of these small mirrors can reach thousands of revolutions, which can cause illusions to the human eye, mixing the flashing three primary colors and seeing the new colors mixed.
This is how DLP technology transforms a piece of white light into a colorful picture. With two artifacts, the color and the DMD chip, the projector can display different colors and screens.
Third, the appearance of: a small robot with no angular angular design
1ã€imea children without screen TV
This infrared detector is the source of the screen protection function of the iime children's non-screen TV. When the object appears in the infrared area, imea will automatically stop the projection for 3 seconds, protecting the child from directing the light into the eye. It is very intimate.
It can be seen that the imae children have no screen TVs and they are completely round and round. This may also be the reason why children can easily bump into the equipment.
2, remote control and dedicated camera
The imea children's screenless TV also comes with a remote control. The early education version also includes a dedicated camera.
底部 At the bottom of the remote control, there is a volume key function key, open the Focus function, the volume plus and minus keys can adjust the focus of the projection screen.
The side of the fuselage, looks very much like a table lamp
Fourth, the functional experience: tailored for children's UI AR early childhood education is also quite bright
Imea children's screenless TV is a product for children, does it mean that its hardware is also very "children"? The author has collected a list of the top three products of an e-commerce non-screen TV category with a sales volume of 2,000 yuan and conducted simple parameter comparisons:
It can be seen that the iime's parameters not only do not lag behind competing products, but lead in terms of performance, contrast, and battery. It can be seen that polar meters have maintained relatively good value for money while developing imea for children.
The imea children's non-screen TV can be operated via a remote control, or it can be turned on or off by touching the head of the imea. The official recommendation is 2.2 meters to watch the distance, and the 32-inch projection is best viewed.
1, operation
After linking the remote controller, downloading application bindings and other simple preparation steps, you can use imea children without a screen TV. The imae feature is that it shields content that is not suitable for children and only has a built-in healthy version that is suitable for children to watch. content.
The imea main interface has also been modified to be a very cute forest portrait, where each building or animal is an application that allows children to adapt and learn to operate very quickly. In addition, iime will play a very cute background music in the main interface.
The main interface of the imea is mainly composed of the magic school, the story castle, the story, the animated world, my study, the super-mall shopping mall and the setting of these 7 blocks.
Magic World:
Story Castle:
The story:
Animation World:
My study:
Extreme meters mall:
Settings:
In the projection settings, you can turn on eye protection mode designed for children.
↑↑↑ Open eye protection mode, you can see the screen clearly filtered out part of the blue light, the implementation of the mode and the eye on the phone mode is almost the same, with the infrared screen protection function, you can reduce TV all-round stimulation of children's eyes.
2. Watching experience
The biggest factor affecting the perception of screenless TV is the brightness, then how does the imae children's screenless TV behave?
As a comparison, the author used Lenovo's new Air12 (50% brightness, around 150 nits) to shoot on the same screen.
Of course, the meter is not a product that can't make high-brightness products. The imae children's screenless TV may only have a brightness of 60 ANSI lumens, considering the child's eye protection and cost restrictions. However, from the actual experience, imea also basically meets the viewing needs of children.
3, AR smart early childhood experience
The AR smart early childhood education system is an additional feature for preschool children that is the main theme of iime. You need to purchase the imea early education version or purchase a dedicated camera separately.
What is the specific AR method?
In fact, it's simple. Isn't the camera equipped with a matching card? After opening the companion application, the application will indicate a number, letter, or pattern that will allow you to pick the correct card under the camera.
The supporting application will use the camera to identify whether you put it correctly, and tell you the result, the use of the jigsaw puzzle is also roughly the same.
Although the AR smart early childhood education system seems relatively simple, but through the matching application and the camera, to achieve the screen and children's interaction, it can indeed improve children's enthusiasm for learning.
Fifth, APP experience: remote intercom parental control do not think that go out can not control you
The imea children's non-screen TV also has a matching mobile phone APP, which displays a two-dimensional code to remind the user to download.
Sixth, summary: imae children without screen TV best gift for children
Appearance: The imae children's screenless TV can not only prevent children from accidentally bumping, but also can be turned into a small robot with a blind-type display, so that a simple device can be fun.
Child protection: as a screenless TV specifically for children, imea has done enough protection work, infrared automatic screen to prevent children from accidentally walking to the front of the projection; eye protection mode, filter blue light, reduce eye irritation; parents control remote intercom It also controls the time the bear children watch TV.
Get started: iMea's interface is very cute and simple. In the absence of arithmetic problems, children can only operate a few applications, and animation and story types are also abundant.
AR smart early education: With the camera, imea no screen TV can identify children's movements and interaction, greatly enhancing the fun of early education applications, but also can stimulate children's initiative to identify learning.
Overall, imae children’s non-screen TVs performed well as the first product for the children’s market.
Children's but not "children's" configuration, comprehensive children's eye protection, rich children's audio and video resources, cute and lively customized UI, and supporting AR early education have greatly improved the ease of use of imea children's screenless TVs. Availability.
At a price of around 2,000 yuan, imea children without a screen TV is undoubtedly one of the best health gifts for children.
