"Think there's a problem with the screen size?" Du Jiayi asked.

Wu Wei nodded.

When Du Jiayi took out the LCD screen patent sales contract, Wu Wei's thinking was swayed by Du Jiayi, especially when he knew that the amount was as high as 100 million US dollars, Wu Wei was already impressed by Du Jiayi's courage.

In the entire field of electronic products, dare to invest 100 million US dollars, just for a patented technology, except for Du Jiayi, it is estimated that there is no one else.

China is still in the stage of imitation and plagiarism, and many domestic mobile phones directly copy foreign shapes and technologies, without considering the issue of technology patents. In the southern coastal city, a family workshop used the motherboard produced by Shangwanwan, with a plastic shell and a speaker speaker, and then bought a matching battery from Shenzhen, and a mobile phone was produced. There is no technical content, and there is not even a brand, so you can enter the market by sticking it casually.

More licensed telecommunications companies are also powerless to reverse the reality of the bottom market share, and can only buy a large number of bare metal from South Korea and island countries and sell them under their own brands.

And Du Jiayi's emphasis on patented technology makes Wu Wei, as a technician, feel sorry for him. Due to the domestic market environment, some people pay attention to appearance, some people pay attention to publicity, and there are really not many people who are willing to invest heavily in technology. As the saying goes, a man dies for a confidant, and a woman is a person who pleases herself.

Wu Wei was actually shocked by Du Jiayi in his heart.

"There is still a lack of technology, which has been purchased from American companies, and it is expected to be around 50 million dollars." Du Jiayi said lightly.

And Wu Wei has no other emotions except shock and shock.

100 million US dollars, plus 50 million US dollars, Du Jiayi took over Luo Feng, and has invested 150 million US dollars in advance, which is converted into RMB, which has exceeded one billion!

If it weren't for Wu Wei knowing that Du Jiayi's thinking was not chaotic, that he was organized, and that he also had professional contracts and plans, he would have felt that Du Jiayi was a rich second generation with money and nowhere to spend.

"Another technology is capacitive touch screens." Du Jiayi revealed the bottom line to Wu Wei.

Wu Wei is obviously the key to reconstructing Luo Feng, and according to Zhang Heran's investigation, Wu Wei's technology is reassuring enough and sensitive enough to be the new person in charge of Luo Feng.

At the beginning of the year, the American fruit company launched a music player with a capacitive touchscreen that could also play some videos that were not particularly large. Not only is it beautiful, but it also has a unique and user-friendly way of operation and a huge capacity.

Originally, the fruit company had the ability to lead the music player, and the exquisitely designed music player was popular in many countries, which made the fruit company that was already in debt crisis breathe a sigh of relief.

The use of capacitive touch screen, in the music player, gets rid of the cumbersome buttons, and has a more sense of science and technology. It has already been released and detonated the entire market, and there is no sales of products of the same type at all. Consumers would rather save money to make a fruit player than settle for a low price.

A capacitive touch screen can be simply seen as a screen composed of four layers of composite screens: the outermost layer is the protective layer of glass, followed by the conductive layer, the third layer is a non-conductive glass screen, and the innermost fourth layer is also a conductive layer. The innermost conductive layer is the shielding layer, which plays the role of shielding the internal electrical signal, and the middle conductive layer is the key part of the entire touch screen, with direct leads at the four corners or four edges, which is responsible for the detection of the position of the touch point.

When the user touches the capacitive screen, due to the electric field of the human body, the user's finger and the working surface form a coupling capacitance, because the working surface is connected with a high-frequency signal, so the finger absorbs a very small current, this current flows out from the electrodes on the four corners of the screen respectively, and theoretically the current flowing through the four electrodes is proportional to the distance from the finger to the four corners, and the controller obtains the position through the precise calculation of the four current proportions.

Of course, there are still many problems with the capacitive touch screen in the hands of the fruit company, which is why the music player uses a very small screen. Once the screen is too large, the effect of touch will be greatly reduced. The capacitive screen is seriously reflective, and the four-layer composite touch screen of capacitive technology has uneven transmittance to each wavelength of light, and there is a problem of color distortion, and due to the reflection of light between the layers, it also causes the blurring of image characters.

As the core technology and user experience of the fruit company's music player, the price of wanting them to sell this technology is definitely not small, and even the fruit company will directly refuse Du Jiayi's request out of competitive considerations.

However, Wu Wei is not clear about this, and Du Jiayi has no problem fooling him at all.

With a color LCD screen and capacitive touch technology, Wu Wei directly came up with the appearance of the finished product in his mind.

There is no keyboard, it takes full touch technology, and the color HD LCD screen is ......

Where is this mobile phone, this is a work of art!

Wu Wei couldn't help but boil with enthusiasm.

The LCD screen is a technology that was born many years ago, and many companies' products use this technology. Capacitive touch screens are also readily available, and the use of them in music players has caused the stock price of fruit companies to skyrocket.

Almost 100% praise, especially the touchscreen full of sensibility, made the major newspapers and magazines shout: this is the future.

But no one seems to have thought of adding touch control to the LCD screen and adding a call function to the music player to make it a mobile phone!

It's an innovative mindset that can change everything.

It's very easy to operate!

Wu Wei thought.

Both technologies are off-the-shelf, and there may be a lot of things to add to the motherboard when they are put together, especially the CPU has to be customized. It will take a long time for this mobile phone to appear, but after Du Jiayi bought the patent for the LCD screen and sent people to negotiate the technology of the capacitive touch screen with the fruit company, everything seems to be within reach.

"It's going to be a new era!" Wu Wei said affirmatively.

"Of course this is a new era!" Du Jiayi said with a smile, "My Yijia network has a preliminary architecture on the mobile phone operating system, and I believe that when the prototype appears, the operating system will probably be able to enter the physical application!" ”

"Do you need a dedicated operating system for your phone?" Wu Wei was shocked again.

In the past, mobile phones needed very little programming to use, after all, their basic functions recently were to make calls and send text messages. The music mobile phones that have appeared on the market recently are just putting some of the functions of the music player on the mobile phone, and there is no substantial breakthrough.
