Li Jun saw that the people below were almost discussed, so he said, "Polycarbonate, in fact, to put it bluntly, is also a kind of plastic, but it is different from ordinary plastic. It has a well-balanced mechanical properties, several properties, and thermal properties. You may not understand this. ”

"It can be used for a long time from -60° to 120°!"

"Oh!?" exclaimed the audience.

Ordinary plastics, you can't do this at all.

"The most important thing is that it doesn't deform easily. I believe many friends know that the back cover of the mobile phone battery, after opening and closing for a long time, will be deformed, resulting in a loose seam. Polycarbonate can solve this problem very well. ”

"And that's not the most critical either. ”

All were intrigued.

"What's the most important thing?" Li Jun paused, looking at the audience looking at him with a very expectant look.

"I think that a mobile phone is often in contact with people, so the importance of hand feel is self-evident. ”

"Polyester carbonate, in your hand, you will feel a warm and jade-like feeling. This is something that other materials don't have! Through different processes, it can be made into a different feel. ”

"Do you feel looking forward to it?" asked Li Jun with a grin.

"Yes!"

"So how do you get the best feel?"

"I think the main thing is weight and thickness, what is the thickness of the mobile phones on the market now?"

"15 mm, 20 mm, this is a smart machine. 10 mm and 9 mm, this is an ordinary microcontroller. ”

"Why is the smart machine so thick? The main reason is that there are too many motherboard components and not enough integration. The resistive touch screen is too thick, and the strength of the engineering plastic is not enough. ”

"So, how thick are our phones? I don't like bricks, so I've asked engineers over and over again to make sure it's a little thinner, even if it's just 0.5 mm, it's a great improvement!"

"With our tireless efforts. We ended up with a thickness of 9 mm!"

"Wow!9mm!" exclaimed from the audience.

Doesn't it mean that this smart phone is equivalent to an ordinary feature machine that focuses on being thin and light!? In this era, only non-smart devices can be thin and light.

Compared with international manufacturers, it can also be said to be top in terms of thickness.

"The appearance and grip are very good, but the experience of a mobile phone cannot only rely on the feel, it must have connotation! Therefore, we also use the top processor in the hardware. ”

"The main frequency is 256MHz, 256M memory, equipped with 4GB storage space, and it also supports up to 6|4GB TF memory card. ”

"You may not be very clear about the concept of storage, and other manufacturers have not popularized it, so I will talk to you about it now. ”

"Memory, which means the computing space of the application, is more straightforward, it is equivalent to the memory module of the computer. As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory. Therefore, the size of the storage is the key to whether the system can be smooth. ”

"I don't know what you think of such a configuration?"

"Good!" followed by a round of applause.

Li Jun smiled slightly.

"So, what is the most intuitive experience for users? This involves the screen, in the era when most mobile phones are still in the era of black and white screens, very rough color screens, and resistive touch screens with a very bad touch experience, we have worked with Sharp to develop a new type of mobile phone screen. ”

"You must have seen it before, there is no commonly used stylus in the video, and there is no use of fingernails, just a light touch with your fingers. ”

"What is it?"

"The innovation of the times!, capacitive touch screen!" Li Jun shouted excitedly.

Although I have too many capacitive touch screen mobile phones, but, in 04 years, the concept of capacitive touch screen has just been produced, and only Sharp is researching.

Apple, the original applier, didn't apply it until two years later.

Now it's different, because of his own joining, let Meng Qiang bring Sharp some information that he knew from the previous life.

Directly accelerate the initial research of Sharp's capacitive screen to the end product soon!

Sharp is excited, this is a product of the times!

So I made up my mind to cooperate with Warwick, there is no way to cooperate without cooperation, Huawei has made a capacitive screen in Panda Group, and has applied for a patent.

And judging from the data, Warwick's technology is very mature, and it is not a loss to work together!

Because the screen is a highlight, it has been kept secret from the beginning when Meng Qiang was explained, and no one knows.

The reporters of various science and technology channels, looking at Li Jun's excited expression, immediately understood that this must be a great thing, and immediately recorded what Li Jun said.

The hearts of everyone present were full of questions.

You've never heard of that name.

"You must be wondering, what exactly is a capacitive touch screen? ”

Li Jun pressed the remote control in his hand, and the structure of the capacitive screen began to be displayed on the large screen.

"Capacitive touch screen technology works using the body's current sensing"

"Capacitive touch screen, compared with the resistive screen, the use of capacitive touch screen is more convenient, for the screen you need to use the organism (finger flesh), not the fingernail to press vigorously, so that the screen will not leave unsightly scratch marks, and the response is sensitive, which is not possible with the resistance touch screen. Moreover, capacitive screens are a trend in touchscreen mobile phones, which are brightly colored and power-saving compared to resistive screens. ”

"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 capacitor, because the working surface is connected with a high-frequency signal, so the finger absorbs a very small current, this current flows out of 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. It can achieve 99% accuracy and has a response speed of less than 3ms. ”

"Precision, that's a huge advantage. Resistive touch screen, I believe everyone has used it, and if you want to achieve relatively high accuracy, you can only use the tip of the stylus. I think it's very inconvenient. ”

"Who would carry it with them? Even if the pen is designed into the inside of the phone, but because the pen is too thin, the experience is not good. With your fingernails, you can easily scratch the screen. The outside of the resistive screen is just a layer of plastic. ”

"What about our screens, glass, and we all know where the advantages are, right? Glass transmits light very well, so our screens are more vibrant than other screens. ”

"Oooo The audience cheered and applauded.

Li Jun suddenly felt that it seemed good that there were more people at the press conference, but this kind of atmosphere alone could not be felt at the later mobile phone press conference!
