What is the principle of ink screen? Is it harmful to eyes (Huawei ink screen tablet function)

Ink screen and e-book are not necessarily directly equivalent.

For mass users, it is easy to confuse these two words. Ink screen is the general name of display technology and display materials, and e-book refers to a product form. Generally speaking, e-books use ink screens, but until today, ink screens can't completely refer to e-books.

Tracing back to the source, when the ink screen first appeared, it was naturally applied to reading. Because of its unique lighting technology principle and power consumption, it can be directly ignored. Compared with color screen, its product form is "e-book".

The advantages of e-books over traditional books need not be said. The most successful e-book is the kindle launched in 2007. The $399 e-book was an unprecedented success as soon as it went on the market. With its compact appearance, friendly screen and the ability to download resources directly from hundreds of millions of Amazon websites, Kindle became a hit in American bookstores.

If Apple is the pioneer of APP software, it is no exaggeration to say that Amazon kindle has created the era of e-books.

After that, Amazon launched a series of products such as Kindle Youth Edition, Kindle paperwhite and Kindle Oasis. With this wave of e-books, there is a famous saying on the Internet: quot Pigs will be blown up when they stand in the wind. When domestic manufacturers such as Shi Wen, Zhang Yue and Xiaomi Duoduo and domestic manufacturers such as Hanwang, Job and Iflytek emerged with more localized book services, better hardware and more open source systems, Kindle was quickly shelved by users because of hardware, service and price problems, and online is the most convenient way to ridicule instant noodles.

Whether it's a foreign kindle or an e-book launched by a domestic brand, its main function is quot reading quot. Even if the screen is thinner and the refresh rate is higher, if only one function is used, the final result is still too single. This may be the best way to solve the problem.

Today, more than ten years later, the mobile phone screen can reach 7 inches, so this kind of "e-book" only provides a single function, which is somewhat unattractive to the mass users who are used to reading books and consulting materials on their mobile phones.

Huawei launched MatePad Paper, a tablet computer with ink screen technology, at the full scene conference in March. Nowadays, e-books seem to be out of date. What is the purpose of Huawei to launch such an ink screen product with a price of 2999 yuan?

As a quasi-pollen quot, I naturally want to experience it in detail. In addition to the brand "obsessive-compulsive disorder", I actually value the same brand operated by "Internet". Through the advantages of quot circulation quot HarmonyOS system and multi-screen collaboration, we can really avoid duplication of work to some extent and improve the efficiency of some usage scenarios.

Of course, in the process of multi-screen collaboration, it is inevitable that there will be too many screens, and sometimes people will be overwhelmed. For example, when I want to write some articles, I really want to look up information while watching videos. I want to play some games after looking up some foreign words on my mobile phone. When you start writing an article, your watch will remind you to stand for one minute.

This process of existence will really affect the efficiency gt;

Therefore, it is necessary to mention the concept of quot Huawei MatePad paper: In addition to quot e-books, it provides more immersive and uninterrupted experiences for researchers in professional fields who need to read a large number of documents or editors who need to review a large number of manuscripts.

As we said at the beginning, the problems faced by ink screen equipment at present can be simply summarized as a single use scenario, which can only be used as quot reading quot. Some advanced ink screens support annotations, but there is also a great delay in writing. In addition, it is not convenient to transfer files. Import and export may require a physical memory card or wired connection, what's more, some products also need proprietary software import, which greatly increases the inconvenience.

No matter how good the display effect and design are, users will be confused by this "design" and finally "degenerate" into instant noodles.

Huawei MatePad Paper may be the best solution we can find after seeing the above problems.

Huawei MatePad paper can be divided into quot two quot transmission logic, which is summarized as follows:

One is to use the distributed operating system with the advantages of HarmonyOS system to transfer the graphic content of quot mobile phone, tablet and notebook to Huawei MatePad paper. The operation mode is also very simple. Only use the "HyperTerminal" function drop-down menu of HarmonyOS system to suck and rotate.

Or simply act as the second display screen, and "drag" some high-density and plain text content to the graphic input board through the mouse.

Although this function is very convenient, we still need some Huawei notebooks with computer housekeeper installed, which indirectly raises the threshold for use. It can easily transmit quot without Huawei equipment?

It is necessary to talk about the second one, and directly regard the inkstone as a normal tablet computer. Huawei MatePad Paper has built-in app store, which can download commonly used graphic information software such as Today's Headline, Netease News, Sina Weibo, etc. As far as the overall use is concerned, it is not a big problem to browse information normally, but when encountering a video, because of its own ink screen characteristics, even if quot smart refresh quot is turned on, there will still be quot stuck on the video screen, so it is not recommended to watch the video on a tablet computer.

What is the performance of an ink flat panel display that can be installed with various applications and has global handwriting function? What about the delay?

The first thing to know is how the ink screen works. Of course, the name ink screen does not mean that there is really ink on the screen. It is actually a positively charged black particle, and together with negatively charged white particles, it forms a "microcapsule" containing electric pulses. In this way, after the black and white particles are charged, due to ionization, they will be concentrated on the top of the screen under the action of charges, thus displaying the content.

In addition, because the ink screen itself will not flicker, there will naturally be no PWM dimming and DC dimming problems. Most ink screens only display black and white, so there is no "blue" problem.

Generally speaking, it is closer to "paper". I used it for 2 hours in normal light and at night, and my glasses didn't hurt. In addition, the flat panel also supports light adjustment. Just click/slide the drop-down menu. It is recommended to set the night brightness at
