Chapter 668: BOE

"Anyway, you are proud, and in a few years, the communication companies in this world will collapse one by one."

Yang Yi shook his head slightly, "It's still early, this market value is too big, and we won't be able to eat it in three or five years; Let's talk about the current situation of the display, what are the problems. ”

Now the cooperation between Star Group and BOE on IMAD display technology, after BOE gave up, Star Optoelectronics Laboratory has already achieved some results; IMAD (Interferometric Modulation Technology) screens are already available on some products.

Interferometry is the technique of obtaining information through interference phenomena caused by the superposition of waves, usually electromagnetic waves.

This technology is important for the study of astronomy, optical fibers, engineering metrology, optical metrology, oceanography, seismology, spectroscopy and its applications in chemistry, quantum mechanics, nuclear physics, particle physics, plasma physics, remote sensing, biomolecular interactions, surface profile analysis, microfluidics, stress and strain measurement, measurement, and optometry.

In fact, this kind of "display technology" has appeared on the butterfly as early as hundreds of millions of years ago, the colorful butterfly wings are a high-tech "display", the dead leaf butterfly uses them for "optical invisibility", and the black vein golden spotted butterfly uses their black and orange wings to express "don't mess with the brother, it's poisonous".

Some of these colorful colors come from the colored substances in the scales, and some from the subtle structure of the scales, and the light creates complex interference diffraction phenomena on the upper and lower surfaces of the transparent wing scales, resulting in a "selective" reflection of ambient light, thus presenting a variety of richer and more gorgeous color expressions that are far superior to skin pigments.

However, the colors and patterns displayed on butterfly wings remain the same throughout life, and in order to apply this display technology to human life, they need to be moved.

The most common interference phenomenon is that the oil droplets, which are close to colorless and transparent, diffuse into an oil film on the water surface, but produce a very brilliant and gradually changing color pattern.

The reason for the variety and change of color is that the water surface is not completely static under natural conditions, and the wind vibration and other reasons will lead to small bullying on the water surface, which in turn leads to uneven thickness of the oil film on the water surface.

However, the interference and counteracting effect of different thicknesses of the oil film on the light is different, so the final pattern of flow change appears.

The method chosen by Star Group is to introduce MEMS microelectromechanical technology to achieve a "film of air" with variable thickness, so as to control the color reflected at specific points.

MEMS simply means that the technology of making CPU is used to create micro-machines, these electromechanical systems of a few millimeters or even smaller contain sensors, actuators and energy parts, which can greatly reduce the volume of related mechanical equipment, in the nozzle of inkjet printers, digital micromirrors of D1P projectors, and also have a very wide range of applications in mobile phone sensors and microphones.

Each pixel on the IMAD screen produced by this new technology contains a reflective film that can move on the micron scale, which moves up and down precisely under the command of the control circuit, changing the distance from the glass substrate above, and finally changing the color of the reflection at that point.

In traditional display technology, each pixel on the screen is composed of sub-pixels of red, blue and green, that is to say, the screen can only produce these three colors of light, but by adjusting the brightness ratio of red, blue and green colors, the three colors of light will become orange, yellow, purple, white and blue and other colors after being mixed with the human eye.

The new imod screen omits this step,Directly reflect the light of the corresponding color,This can achieve the effect of reducing blue light to protect the eyes,Second, the water droplets on the imod screen、Fingerprints will not be refracted after the light,Resulting in the dislocation of sub-pixels makes the picture colorful and annoying。

However, this also brings a new problem,The specific color of each point on the imod screen is completely related to the moving distance of the reflective film,The accuracy of the latter positioning determines the number of colors that can be displayed in the end,At present, the number of colors of the first generation of the new imod screen is undoubtedly not as good as the traditional 1CD,After all1CDhe only needs to adjust the driving voltage of the sub-pixel liquid crystal,The latter also involves the mechanical movement of hundreds of thousands of internal reflective films,The difficulty of control is undoubtedly a lot more surging。

It's just this problem, although the Star Optoelectronics Laboratory has long made a prototype of a mobile phone equipped with this IMAD screen, it has not been put on the market at the first time, and even the second-generation Star mobile phone has not been carried.

It wasn't until not long ago that Yang Yi vacated the time and led the team to solve several key problems, and finally it was ready for commercial use; However, the products launched now are not hot-selling products, because several major product lines of Starry Sky have not yet reached the time period of new fabrics.

Then you can only use new products to warm up the market; Now the new product is e-books, after the acquisition of Shanda Literature, the star is already the leader in text reading, and there are also some achievements in the fields of comics and light.

With this foundation, it is naturally suitable to launch e-books; First of all, it is a free product for the majority of Star Reading Senior VIp members, and the Star Reading Senior VIp members need to spend 4999 yuan to achieve, and an electronic product that costs no more than 1,000 yuan is naturally worth giving away.

The listed price is 1999 yuan, which is suitable for reading comics, documents, drawings, and e-books; It is equipped with a customized APP client of the starry sky, which can be connected to the Internet through IFI.

At this time, the screen of the e-book reader is mainly the eink electrophoresis screen, and there are also LCD color screens; The former can only display black and white images,But the advantage is that the power consumption is low and can continue to read for several weeks,The latter is actually from the original color screen mp4 or Symbian、Android tablet computer changed,Low performance and insufficient battery life,But the price is cheap or color screen,You can also watch videos。

It can be imagined from this that the dilemma of the imod screen, the price is more expensive than the eink, the color is not as good as the LCD screen, and it can't be beaten at both ends, and in the end it seems that it can only be a cup.

Although in the past year, there are a number of manufacturers who claim to "jointly launch an e-book reader based on imod technology in the United Star Optoelectronics Laboratory", in fact, they are just holding the first generation of waste iMod screens produced by BOE for market warm-up, and because the yield rate of the first generation iMod screen is not high, in fact, it has not been sold on a large scale.

In addition, the product of e-book reader is following in the footsteps of consumer digital products such as DC and MP4, and has been defeated by more convenient and all-round smart phones, and the market is shrinking.

It is also in this context that seeing that the business has not improved for several months, BOE has given up the idea of recovering the cost of the first-generation technology and working hard to develop the second-generation screen that is more suitable for mobile phones.

The Star Group, on the other hand, did not give up, and began to conduct independent research after acquiring the share of the first-generation imod technology.

The leader who made this decision was naturally Yang Yi, who had no more confidence, in fact, others were not very optimistic about the imod technology where the color was not fine enough and the cost was still high.

Some people in the group always feel that the starry sky does not need to be like Sony, and they are eager to make everything from processors and flash storage, to mobile phones, cameras, laptops, plastic back covers and handbags, to control the supply chain and reduce costs.

However, Yang Yi's accumulated prestige is still there, and the Star Group is her own company, so the workers can only obey orders.

Because one is willing to buy and the other is willing to sell, and Yang Yi is not very tight on the amount, the transaction between the two parties was completed quickly, just like a local tyrant going to the auto show site to buy all the cars and people.

However, if BOE knew that it would only take half a year to launch an improved version after the Star Optoelectronics buyout technology, although vomiting blood three liters is not necessarily, but there will definitely be dissatisfaction, but Yang Yi can't take care of them, because BOE is not the only supplier of Starry Sky now, BOE is very tight on the shares, and Starry Sky will naturally turn to AUO to help upgrade products.

This time, imod's screen technology is also for AUO to OEM; There is only one main change in the new technology, that is, the other indicators remain unchanged, which greatly strengthens the color performance, making it reach the ordinary 1netbsp; The reason why the first generation of screens failed to be used, the most critical problem is that the picture quality is much worse than 1cd, but it is still much more expensive than the latter.

Although users also criticize the short battery life of smartphones for less than a day, the lack of battery life can be solved by replacing the spare battery or an external power bank, and the poor screen quality can only be endured while making up for it.

In fact,The actual number of colors of the new generation of imod technology has not increased much,Its picture performance has been greatly improved, which can be said to be the result of the viewer's own brain supplement。

To be precise, under the leadership of Yang Yi, the Star Optoelectronics Laboratory modified the underlying drivers and fine-tuned the control voltage corresponding to each color, so that the system could smoothly display the tens of thousands of colors that are most sensitive to the human eye.

On the one hand, digital photos and videos have given up a large number of indifferent details in the process of sampling, transcoding, compression and preservation, many of these details are small differences in color, on the other hand, even if these small differences are displayed on the screen, it is difficult for ordinary people without professional training to distinguish them.

In the history of the evolution of mobile phone screens, there have been 256 colors, four thousand colors, 60,000 colors, 260,000 colors, but after 16oo million colors, it basically stops, manufacturers like to talk about the size, resolution, and viewing angle and color temperature and other indicators when promoting the screen, and no longer emphasize the number of colors.

The main reason is that it is more than 260,000 colors,It is actually difficult for the human eye to distinguish the difference between the two screens,The reason why it stays at 16oo instead of 260,000 colors,Purely because the former has matured and the price is low enough。

So after Yang Yi, a person who "has a plug-in", took action in person, and no longer pursued 16oo million colors, he also completed the revised version of the imod screen with high efficiency, only from the naked eye, and the current color performance immediately soared.

Of course, this improvement effect is not 1oo% effective, and there will be obvious differences in actual use due to the different conditions of the user's eyes, but at least it can impress the eyes of at least one-third of the people, and the remaining part of the people will have to wait for the star optoelectronics to further optimize the color number.

However, in this way, there is no need for Yang Yi to take action in person, after all, there are experts and professional equipment, and then spend money to let them grind slowly.

In addition, it is a layer of coating technology, although the energy-absorbing coating technology makes this screen almost unusable in a lightless environment, but it is naturally beneficial, first of all, it is energy-saving, compared with 1cdThe screen saves at least half of the energy, which is basically equivalent to extending the use time of the same smart device by one-third; The energy-absorbing coating on the surface can further improve the battery life.

In addition, the battery used in the e-book is larger, which can increase the maximum battery life to 17o hours, which is the use time, according to the frequency of use by ordinary people, this can also have at least half a month of battery life.

Even if the energy consumption is increased after the upgrade, the battery life will be at least half higher than that of the existing device.

Nowadays, high-end graphene batteries have been unable to be miniaturized, and the cost of high-capacity lithium batteries has always been very high, and only high-end products of various brands can afford it.

This is also one of the main reasons why Starry Sky can open up the price difference, and the battery life has been increased by about double compared to other brands, which is difficult for people who are not bad for money to justify through marketing.

And now after the screen continues to improve, the battery life of the next generation of Star mobile phone products will be further improved.

The problem now is that BOE has made some small moves in production capacity because of this part, and Andy is solving this problem during this time.

Originally, the cooperation was good, but BOE was unwilling to continue to invest, nor was it willing to let the Star Group expand the amount of shares; In recent years, because of the technical support of the Star Optoelectronics Laboratory, BOE has become the world's No. 1 LCD provider.

In a short period of time, it has passed Sharp, Sony and other Dongying manufacturers; It's not a good thing for this partner to grow too fast, and it's normal for Enda to become enemies, so since last year, Starry Sky has begun to shift some of its share to support AUO, which is more willing to exhibit with Starry Sky.

This has led to the further division of interests between BOE and Star Group, which is inevitable, among the suppliers of Starry Sky, in recent years, BOE is not the first, nor the last, everyone is very open.

"The second quarter of BOE's financial report is about to be clothed, and when the stock price rises to 5 yuan, all the shares in the hands are thrown away, and now Tianma has also signed some supply agreements, and there are still a lot of materials in stock, and the new cloth in the second half of the year can also catch up."
