"Capacitive screen."

Looking at the LCD panel that the man took out, Zhang Ning was extremely surprised.

"It seems that this gentleman also has research on capacitive screens."

found that Zhang Ning knew this panel, and the man in his 30s continued to introduce.

"Unlike traditional resistive screens, our capacitive screens can be operated with the touch of a finger. In other words, the finger is our mouse, we only need to click on the icon on the phone with our finger, and we can use it. I think it's a really great innovation. In the future, the type of mobile phone may use a capacitive screen. ”

Listening to the man's explanation, Zhang Ning nodded.

In fact, touch technology appeared in this world as early as the decades.

Generally speaking, touch technology can be implemented in two screens.

The first is the resistive screen.

The so-called resistive screen, he is actually a kind of sensor, and his working principle is mainly to realize the operation and control of the screen content through guò pressure sensing. However, this kind of resistive screen has great drawbacks. Because he uses pressure to achieve the operation, he must have a certain amount of force when he touches it. Simply touching with his hands, he doesn't work well. For this reason, many electronic devices that use resistive screens are generally equipped with a resistive pen. In other words, if you want to touch, you can use this resistive pen as a mouse.

Of course, you can also do without a resistive pen, and its practical fingernail touch can also be achieved.

It is clear that although through guò resistive screen in this way, he has successfully achieved touch. Moreover, many electronics manufacturers have used such resistive screens in mobile phones. However, this is too much trouble to touch. Either with a pen or with nails, and because of this, he did not have a large-scale popularity.

However, in addition to resistive screens that can achieve touch, there is another technology, and that is capacitive screens.

The working principle of the capacitive screen is completely different from that of the resistive screen, and it is not operated and controlled by pressure. He uses the working principle of human current induction to achieve touch. When the hand touches this screen, due to the electric field of the human body, a small current will be generated when the user touches the capacitive screen. This current flows out of the electrodes on the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners.

Undoubtedly, the capacitive screen is higher than the resistive screen in terms of touch experience, not one point or two points.

Therefore, after the advent of capacitive screen technology, it was widely used in many electronic touch devices.

Like bank ATMs, government office electronic supplies, etc., capacitive screen technology has been widely used.

It's just that Zhang Ning didn't expect it.

Huaxing, which provides LCD panels for those copycat mobile phones, has also kept up with the international pace and began to study capacitive screens.

Of course, this is not what surprised Zhang Ning the most.

Capacitive screen technology actually appeared very early, although his technology is higher than the resistive screen, and it is also higher than the general LCD screen, but relatively speaking, it is not a very cutting-edge technology. Many LCD panel companies, they have successively launched their own capacitive screen panels. However, even so, these LCD panel companies only use capacitive screens, some ATMs, and public office electronic equipment.

That is to say, these LCD panel companies, they have never considered using capacitive screens on mobile phones.

The man from Huaxing Company was the first person to propose to Zhang Ning to use the capacitive screen on his mobile phone.

This is a very big innovation and a very big step forward.

Because, if it really happens.

Then, the touch technology that will change the smartphone the most will also be born.

"Hello, I don't know your last name."

"The contemptible surname is Hua, a star, and this company is also named after me."

Seeing that with his own efforts, the other party had some intentions, Huaxing felt a little relieved.

Regardless of whether the other party can become their own customers, but as long as they persist, who dares to say that Huaxing Company will not be able to become a super-large LCD panel giant in the future.

"Huaxing, I didn't expect that the name of your company actually came from like this. Hello, let's get to know you officially. My surname is Zhang, and I am currently in a newly established electronic company, responsible for the procurement of LCD panels. ”

Zhang Ning nodded, and then chatted with Hua Xing with great interest.

"It turned out to be Mr. Zhang, hello, hello, sit inside."

"Okay."

was originally about to leave, but at this time, Zhang Ning had another idea.

"This capacitive screen of yours is very innovative, though, I want to know. How did you come up with the idea of using capacitive screens on mobile phones? ”

At the reception of the Huaxing booth, Zhang Ning sat on the side and said.

"Doesn't Mr. Zhang think that the touch experience of capacitive screen is better than that of resistive screen?"

Huaxing explained.

However, Zhang Ning was not satisfied with this answer.

"Capacitive screens are certainly better than resistive touches because they can be touched directly with your hands, but that's just a touch experience. Our mobile phones are not meant to be touched by the user. I'm thinking if I used such a capacitive screen as a mobile phone screen. So, how should we operate the phone? ”

"I don't think there should be a big problem, in terms of operation, it can be the same as the operation on the ATM, as long as you see the icon clicked, it is relatively simple, and it doesn't require much learning. At the same time, we can also play some games that can only be played by touch. Like Lianliankan, if a capacitive screen is used, then, when we play Lianliankan, we can only use our hands, and he does not need a resistive pen. ”

"Looks interesting."

It's just that Zhang Ning still shook his head, and then said, "What you said is very innovative, but, I want to ask, how to send text messages or type through the guò capacitive screen?" ”

"This ......"

Faced with this question, Hua Xing suddenly didn't know how to answer.

The question of how to type has also stumped countless electronics manufacturers around the world.

In fact, since the emergence of capacitive screen technology, some theoretical researchers have said that capacitive screen technology can be used in mobile phones. Unfortunately, because the problem of typing on the capacitive screen cannot be solved, there have been few mobile phone manufacturers in the world that have launched mobile phones with capacitive screens.

It's not that they can't think of it, it's that their technology has hit a hard time.

It's like, although resistive screen mobile phones appeared, they have not been popular.

There is only one reason, that is, whether it is a resistive screen or a capacitive screen, he can't solve the typing problem.

Of course, some mobile phone manufacturers have also thought of solving the problem of typing.

Mohandola launched a mobile phone with a resistive screen last year, and at the same time, they also came up with a solution.

They install a piece of software inside their phone, which is something like a touchpad used in a computer. If you need to type, then the user can take out a resistive pen and write on the mobile phone screen to type. Although, this way seems to solve the typing puzzle. However, this way of typing has a very, very high error rate. Write almost a few words, and there is a chance that mistakes will occur. And after the error, it has to be rewritten. Of course, even if there are no mistakes and 100% correct, his typing efficiency is also very slow.

It couldn't be more convenient and faster than typing with a keyboard.

Therefore, last year's sensational resistive screen mobile phone has slowly faded because of the problem of typing.

Up to now, the world's top ten mobile phone brand companies have never launched a resistive screen mobile phone in the newly launched mobile phone models.

"It's already very difficult to type on such a small mobile phone screen with a resistive screen. I think if you use a capacitive screen. Based on the size of our mobile phone screen of about 2 inches, the width of one finger is at least 1 cm. Using our fingers as a pen to write is probably going to be a huge problem. ”

"I'm sorry, Mr. Zhang, but I don't know how to answer this question. I just think that the touch experience of the capacitive screen is really very interesting. If it is used on a mobile phone, it will make the mobile phone very innovative. As for how to solve the capacitive screen typing, I think that in the future, there will be technicians who will be able to achieve it. ”

"I think so too."

Zhang Ning nodded.

"I think that in the future, all mobile phones will probably use capacitive screens."

"Oh?"

Hua Xing was taken aback.

In the future, all mobile phones will use capacitive screens, how is this possible.

You know, just now he said that the capacitive screen is used on the mobile phone, which is just an idea.

He also knows that capacitive screen technology is actually flawed.

"Of course, I think it will. So, I think. Instead of making these low-end LCD screens, your company should upgrade and make more high-end capacitive screens. But I'm not talking about you. This capacitive screen produced by your company can be used, but the touch experience needs to be improved. ”

Not all capacitive screens are created equal.

Capacitive screens, like liquid crystal displays, are both good and bad.

Some have good display screens, while others have poor display screens.

The capacitive screen that Huaxing took out just now, although it can be touched, the touch experience is really bad.

Zhang Ning used it just now, and when Zhang Ning touched it with his fingers on this capacitive screen, sometimes the touch was effective, and sometimes the touch did not respond at all. Even, sometimes, it is obvious that it is touching one place, but it runs to another place, which is obviously a technical defect.

In addition to the low touch experience, the resolution of the entire screen is also too low.

Click on a random picture, and Zhang Ning can see that the picture is distorted because the resolution is too low.

"Mr. Zhang, thank you for your advice. This capacitive screen is just our actual product. If we will enter in the future, we are absolutely confident that this capacitive screen will be the world's top. ”

"Can it be compared to Samsung, Sharp?"

Zhang Ning couldn't help but be proud.

"Although Samsung and Sharp have always been leaders in LCD panels, we are absolutely confident that we can compete with them in the field of low-size LCD panels. As for why our company has been doing low-end, I can only say that the domestic market has this demand. Of course, we can also go to the high end. If your company needs a high-end capacitive screen, we can make products with the same panel as Samsung, Sharp and other LCD panel companies. Of course, the premise is still low-size, too large LCD panels, and we admit that they are indeed far inferior to them. ”

"Can you really make it?"

Zhang Ning has some expectations.

"Yes."

Huaxing replied with great firmness.

"Mr. Zhang, maybe you have some misunderstandings about our small LCD panel manufacturers. I don't know if you will think that we only do some low-end ones, and we only provide LCD panels for some copycat machines, which proves that our technical strength is not very good. Actually, no. As I said just now, if it is a large-size LCD screen, we really can't compare with Samsung, Sharp and other giants. However, if it is a small size, our technical strength may not be lower than theirs. It's just that many companies don't want to believe in us and don't want to give us opportunities. ”

Can't help but sigh a little.

Zhang Ning, who was on the side, was also shocked after hearing this.

yes, didn't I always misunderstand them before?

Before, didn't you always think that they were just small workshop-style manufacturers?

The low-end of their products does not mean that their technology is low-end.

They have been producing these low-end products, but there is a market demand.

If they really have a chance, they may not be able to turn pheasants into phoenixes like Meizu in later generations.

"Mr. Hua, your persistence touched me."

Zhang Ning nodded at Huaxing friendly, "We penguins are very willing to cooperate with you. ”

"Thank you."

Seeing Zhang Ning stretch out his right hand, Hua Xing stood up excitedly, not feeling Zhang Ning say the word penguin at all.

"I also want to thank you, if it weren't for you, perhaps, I would consider choosing a foreign LCD panel manufacturer. We can sit down and discuss how we can work together. However, Mr. Huaxing, maybe the products we need are far from being so simple as the current high-end LCD screen, we hope to create a more high-end product than the current high-end LCD screen, this is my business card, tomorrow, I will send someone to your company, specifically discuss. ”

As he spoke, Zhang Ning took out a business card.

The business card shows the contact number of Penguin, but no name.

"Great, thank you for choosing us Huaxing, we welcome you at any time."

Seeing Zhang Ning's departure, Hua Xing took the business card in his hand, still a little incredulous.

Although it is only a preliminary intention at this time, no formal cooperation has been reached.

However, Hua Xing thinks that his vision is very powerful, and he believes that if this list is completed, it will definitely be a big order.

Even, it is possible that Huaxing Company will rise, it is not known.

"Everyone, we're going to have dinner tonight, thank you so much for working so hard today."

Huaxing excitedly announced to the staff at the scene.

"Long live, long live the boss."

"Haha, Mr. Hua, we succeeded."

"yes, it worked."

The staff cheered.

"By the way, Mr. Hua, which company is that gentleman the representative of?"

"He seems to say that their company is called Penguin."

Hua Xing didn't react for a moment, and when he finished speaking, his whole head was completely shut down at once.
