Coquettish Rebirth

What can such an imperfect thing be used for?It's easy!It's easy!That is used as a promotional carrier for businesses, especially supermarkets!That's right, if a merchant wants to promote, the consumption of promotional materials is quite large!First of all, there are various fixed posters posted in the entire shopping mall, such as the posters on the guardrails next to the escalators and elevators?On the wall next to the various snacks next to the escalator, there are posters?Then I walked into the mall, where every product has a price tag?There are promotional signs showing how much the price has been reduced?Then, during the holidays, there are various xx festivals, or promotional advertisements or event advertisements for some products?

Although these things can be made of paper, the cost can be very low, but they have to be replaced every once in a while, isn't it free?But the screen of this electronic paper book is different, there is no size limit, you can make it as big as you want, and the power consumption is extremely low, so in theory, as long as the price can not be too high, it is a good choice for merchants. It is acceptable - for example, a substantial replacement of this kind of stuff, although it seems that the one-time investment is high, but they may not need to use paper promotional materials in the next ten years!This is also cost reduction!Costs are reduced, and profits will increase in the future!

For a small thing like this, the power consumption of the screen is only 0.2 watts. Even if there are 1 such screens in a supermarket, how much power will it consume?Isn't it only 2000 watts? 2000 watts, 1 screens, for businesses, that would be a waste of money, okay?The power consumption of the fluorescent tubes in the shopping mall must be far more than 2000 watts!Moreover, even the power consumption of two kilowatts looks like it will continue to be consumed every day purely from the numbers.But the problem is, it can be used for half a year on a single charge!And in my impression, this kind of electronic paper book is not as easy to break as a tablet, so the repair cost and maintenance cost are also low. Cabinet or something, it really saves electricity and can no longer save electricity!

Perhaps, this thing is not suitable for civilian products to be promoted to the market for the time being, but who said that this thing cannot be commercialized?right?In terms of some requirements for commercial use, it is really not as high as civilian use.The key is power saving and durability.The overall cost is low, this is the kingly way!

After thinking about this, Jia Hongjian asked Professor Chen, "Professor, what about this thing? How long can the storage time be the limit in our laboratory? I mean to maintain a fixed image without power on!" "Professor Chen thought for a while.Then he replied slowly, "The results we did in the laboratory can basically last up to a week. After all, our product does not need electricity to maintain the current display effect, only when it is changed It consumes electricity. However, the results we do are laboratory results after all, and it is not easy to become the results of assembly line operations. On the other hand, we found that such a one-week maintenance effect, after a long time, If you want to refresh the page, there will be a lot of fonts left, and you need to refresh it several times to remove it. This seems to have an impact on the consumer experience, and consumers don’t need to save it for such a long time, so we have tested it , I think it is enough to keep it for a few hours, so that the font remains at the least, and the consumer experience is relatively good, and even a part of it can be kept..."

ha!This thing is so amazing?A content can be kept for a week?So if there is such a level, obviously the power consumption will be lower!After all, people have said that this thing only consumes power when changing the image!And for a week at a time!How long is it now?Then the power consumption will obviously continue to drop!And in this way, it will be even better for shopping malls and so on!Although this practice of keeping for a week will cause some font residues to be refreshed uncleanly, it may be troublesome for ordinary consumers to refresh several times, but for merchants, this is not a problem at all. !

After all, this is something you can just swipe before opening the store one day!Love to swipe a few times, as long as it can save electricity, as long as consumers can see a nearly perfect publicity, it will be fine, merchants will not refresh these things in front of consumers, even in person, consumers will You don't care, do you?After all, they didn't use this stuff to read books!

So at this time, Jia Hongjian still has high expectations for this product!He may not know how many times this stuff evolved before it entered the market and was known to him later, but now, obviously he wants to try to promote this imperfect product!Even if it is unsuccessful after spending money, isn’t there still a Sherlock Holmes platform to sell e-books in the future?Anyway, he won't lose money if he invests, so what is he afraid of?

Then he chatted with Professor Chen for a long time, and learned a lot of product information from Professor Chen, such as the principle of this product-in simple terms, it is like a layer of "swimming pool" sandwiched between two glasses.Inside this "swimming pool" are n bluish "electronic inks" whose diameter is thinner than a hair, and then, when the content to be displayed is converted into electrical signals, these small floating inks will start Divide camps according to electrical signals.For example, in terms of fonts to be displayed, rows of small blue inks are gathered on the "water surface", and the ink drops sink to the "bottom" where it is not displayed. In this way, if the "swimming pool" itself is dyed by fuel If it becomes off-white, then of course the human eyes will not be able to see those little blue inks that sink to the bottom of the water!When it needs to be refreshed, all the small balls are floated up through the electric charge, and then the charge signal of the corresponding font or image is input, so some small ink remains on the water surface, and some sinks.

After these small inks have achieved their own sinking or floating, without the interference of external charges, they will hardly change their state.So for such a thing, it is much simpler than the complex technology of the LCD screen on the whole, and the contrast is also much better-like in the tft LCD screen, n layers of things are required, so the stuff displayed in the end , It is not easy to see clearly, just like the mobile phones of later generations, even if the backlight is turned on, it is not easy to see the display content on the mobile phone in a place with strong sunlight.But under the same light, you can see it very clearly with a paper print!As for the display of such an electronic paper book, because the structure is not as complicated as that of liquid crystal, it does not need so many layers, and the "swimming pool" in the middle is still dyed as the background color, so the overall effect is worse than that of real paper, but comparable to that of real paper. The LCD screen is so much better!As long as the outside light is stronger, this thing can be seen more clearly!On the contrary, it is not clear where the light is not strong!

However, there is a problem with this little thing, that is, the tft LCD screen and the like can be added with a backlight, but this e-paper book cannot be added with a backlight under temporary technical conditions-because adding a backlight is equivalent to changing from " The bottom of the "swimming pool" is lit up, and the water in the pool itself is colored, so the light transmittance is naturally low, and the problem is that there is still so much "ink" under the pool!If the lighting is used to reveal the sinking ink, won't this interfere with the reading effect instead?The result is that with the backlight, the contrast is greatly reduced, and the entire screen is not a white background with blue characters, but a blue-gray background with blue characters. Is this something that people can read?

After hearing this, Jia Hongjian really wanted to invest in this thing, so on the second day, Jia Hongjian and Olsen came to the Multimedia Laboratory of the Massachusetts Institute of Technology, and then talked to their The principal of the school signs an investment agreement.Jia Hongjian invested 1000 million US dollars, Olsen invested 200 million US dollars, and the two together accounted for 70% of the shares of this e-ink company, and mit school invested in technology, talents and equipment, accounting for 30% of the shares. % dry stock.Among the 70% shares, Jia Hongjian alone accounted for nearly 59% of the shares!

After signing the agreement here, Professor Chen and the principal looked at Jia Hongjian the way they looked at Lei Feng.Professor Chen, in particular, seemed a little embarrassed, "Mr. Jia, no, Mr. Chairman, I'm sorry, our current products are still far from being launched, and we may not be able to launch products suitable for consumers until next year..." But who knows, Jia Hongjian smiled brightly at this time, "It's okay, we can launch commercial products now!"

Then, Jia Hongjian began to talk about the product idea he designed for merchants, especially large supermarkets and shopping malls.After he said this, at that time, whether it was Professor Negroponte, the principal, or even Olsen, everyone looked at Jia Hongjian in surprise. None of them thought that this Jia Hongjian could be so fast. Just design a market direction!When I was going to show him the market research report yesterday, the young man also said that he himself was the market research report... Could it be true?Could it be that he decided to invest only after thinking about how this product should be applied at a glance?Is it that exaggerated?

But surprises are all surprises, the various concepts Jia Hongjian put forward are quite attractive!If we follow what Jia Hongjian said, it is true that commercial users are not so demanding whether there will be residual problems after long-term storage, and this kind of display screen is also quite a gimmick from a certain point of view. Not to mention the application of paper can also be reduced a little.If it is really the first company that can make it low, it will really save money for the merchants, and allow them to play high-tech gimmicks, and even use the name of environmental protection, paper saving and tree protection to attract those extreme radicals who are green and environmentally friendly. activists...
