A screen sticker that can charge solar energy and transmit data through light

Almost every smart phone manufacturer has tried to charge smart phones in some way. However, at present, basically none of them can fully meet consumer expectations or usage habits, which is not very convenient. These traditional methods either have to put the phone on a special base, or have to put a big, heavy box on the phone. Although it is wireless charging, the whole process is very troublesome. Now, SunPartner and 3M have jointly brought us a new solution that not only helps us solve the problem of poor battery life, but also provides consumers with a completely new way of data transmission.

Solar charging

This new invention, called “Wysips,” is a thin layer of crystal glass that can be embedded in devices with small and medium screen sizes, such as smartphones, watches, and tablets, and then used as a solar panel. effect. Under normal circumstances, Wysips are completely transparent, and ordinary people can't see that this is a solar panel. It will not affect the user's normal operation during use. When there is sunlight or artificial light shining on the screen of the mobile phone, It will start working and charge the phone.

"As long as there is light, it will inject a little power into the phone," said Matthieu de Broca, head of business development and strategic alliances at SunPartner. "In the course of normal use, if this new technology is used, it can provide users with an additional 15% of the power."

Battery technology has not been as rapid as the smart phone itself, so this extra 15% of the power can sometimes solve many big problems (if you specifically put the phone under the light source for charging, it will bring more extra power). This new technology can theoretically help many people who forget to carry the charger or can't find the power supply so that the phone can be used for a longer period of time. The addition of this miniature solar charging panel can greatly increase the power of mobile phones.

This latest wireless charging device, if applied to some E-Ink electronic ink display devices, such as Kindle, Nook or small smart watches, can almost completely free the user from the dependence on the charger. The old model is not very big for the power consumption of mobile phones, the same can be completely through this new wireless charging device does not require a charger to charge.

Effect

The cooperation between SunPartner and 3M is very clear. The former is responsible for producing the glass panel film, while the latter is responsible for applying the new panel with a special adhesive to the mobile phone, and can make this new charging panel and mobile phone. The internal hardware connection is like DT technology.

We looked at this solar charged Wysips panel. It looks very transparent, but if you look at it from different angles, you can still see some sparkling phenomenon. If you observe it carefully, you can even see the solar crystal modules vaguely, just like the grid-like distribution on ordinary solar panels. We use an ordinary smart phone for demonstrations. When this type of solar charging panel is attached, although this kind of charging layer is not obvious, there are still some impacts on the viewing angle. However, since the models we tested are not flagship, their own screen effects are not the best. Therefore, although Wysips may have some impact on the screen, it is not too large.

SunPartner and 3M have stated that they have already found a relatively well-known mobile phone manufacturer to cooperate, and the first mobile phone to use this solar charging panel will be officially released in 2015.

Supports Li-Fi optical communication technology

Solar charging is a very great technology, but what we want to see next is a much coolr thing. At the CES 2014 Consumer Electronics Show held earlier this month, Wysips charging panels have announced support for Li-Fi data transmission technology, a new technology that can send and receive data via light waves. It is also known as VLC or visible light communication. technology.

The process of optical data transmission is very simple. If the user places the phone under a special light source, information and data can be sent to your phone by blinking at an inconspicuous light frequency that is not recognized by the naked eye. Compared with Wi-Fi and Bluetooth technology that use radio waves to transmit data, this optical communication technology is higher in speed and security. Li-Fi technology can achieve a transmission speed of 3.5GB, which means that each set of red, green and blue (RGB) LED lights can transmit four degrees at speeds up to 10.5Gbps, which is 10 times faster than ordinary Wi-Fi. At the same time as Wi-Fi can convert wired connections into wireless networks, Li-Fi can also convert fiber data into high-speed light sources.

However, we cannot expect to connect to the Internet through optical communication technology in the short term. At present, this kind of technology still remains in the demonstration stage. Just put your phone under a special light source, you can automatically open a video, web page or application. The future can also be applied to commercial areas. When a user walks into a restaurant or store, data such as coupons or promotional information is automatically received.

"Multiple use of a film"

According to Broca's introduction, the cost of Wysips is not particularly high. The cost of manufacturing each panel is only about 2 to 3 dollars (about 12 to 18 yuan) or even less. This is much cheaper than many other new technologies of its kind. This means that Wysips can be applied to products in the next few years with lower cost advantages. So this is not just a cool technology, but it is also a very promising product that is actually used.

Nothing is more exciting than being able to recharge with solar energy. Kindles, smart watches, etc. can be completely free from chargers, and ordinary smartphones can also get at least 15% more power, plus support. Li-Fi optical communication technology, I believe all this will make the equipment in our hands become better and better. All this need only be based on adding a small layer of “foil” to your mobile phone, and the cost is not too high. Therefore, the new technology jointly developed by SunPartner and 3M is really very exciting.
