Chapter 312： take money

Professor Huang helped his eyes on the bridge of his nose, a little surprised that Chen Yang's first question was this,

But he didn't care, maybe the boss saw the information from somewhere, and he got it here to show his presence,

Then he smiled and explained patiently, "This is a resistive screen. Compared with a capacitive screen, because of the foundation of PDA technology development before, the resistive screen technology is more mature and the price is relatively cheap. Therefore, the current mainstream mobile phone market is is the resistive screen used,

For example, Jinli, Ham Sausage, and Duopoda have all launched touch-screen mobile phones, especially the two brands of Duopoda and Jinli. A1200 and a new mobile phone launched this year are also resistive screens.

In contrast, there are relatively few mobile phone brands using capacitive screen technology. The more well-known ones seem to be South Korea’s LG and Apple in the United States. LG released it in December last year, and it seems to be the world’s first capacitive screen product, while Apple It was released in January this year, and the release time of the two is not much different, just a month or two ago,

Only limited by technical conditions, their screens can only be up to 3.5 inches, and LG's is only 3 inches.

Judging from the current market feedback, LG can not be mentioned, and its sales are limited, so it cannot be used as a reference.

As for Apple's mobile phone, I can only say that it is average. It is mainly purchased by Apple fans. Although it is said that the response is not bad, most of the opinions of such users need to be discounted.

Therefore, after comprehensive consideration, I think it is better to use a resistive screen. "

Convincing with reason and evidence,

Unfortunately, the overlord of the future mobile phone screen is the capacitive screen!

Silently sighing, Chen Yang nodded, looking at the phone in his hand,

Black casing, boxy shape, almost four-inch mobile phone screen, there are three buttons at the bottom of the mobile phone? ? ?

Hang up button on the left, home button in the middle, answer button on the right,

Well, he remembered, most of the touch screen phones at this time seemed to have buttons, and some even had full keyboards!

I don’t know why touch screen mobile phones are equipped with keyboards. Is it because the screen is broken and cannot be used?

Fortunately, there is no row of white icons at the bottom of the screen, otherwise it would be too much.

I looked at the side and saw that there was no side button, so I tried to press the home button. Sure enough, the screen lit up.

It is somewhat similar to the mobile phone pages of later generations. The home page is a bunch of big icons, but there are no such common software.

I reached out and clicked, but there was no response.

At this time, Professor Huang quickly said, "The resistive screen is based on pressure sensing. You need to use a stylus. The stylus is on the top of the phone and can be pulled out, or the fingernail can also be used."

"No," Chen Yang raised his head and smiled, "I'm looking at the touch of the screen, it's a bit soft."

"Yes, softness is one of the characteristics of resistive screens, and capacitive screens are very hard because they have an outer layer of glass."

Professor Huang said with a smile, "Although it is a bit soft, it does not mean it is easy to damage. This is because the precision of the resistive screen can reach a single display pixel, which can be seen when using a stylus, which is convenient for handwriting recognition.

Capacitive screens are worse in this respect, limited by the contact area of ​​fingers, and the accuracy is far inferior to resistive screens. "

Chen Yang pursed his lips and swiped his fingernails across the screen. Sure enough, there was a reaction, and the speed was not too slow.

Then turn off the screen and take a closer look at the surface. It seems that there are no scratches with the naked eye.

Professor Huang laughed again, "This kind of screen has a certain service life, but within half a year, as long as it is used at a normal frequency, there will be almost no obvious scratches, and it will wear out after a long time."

"Uh," Chen Yang thought for a while, and said, "That is to say, if I buy this phone, after half a year, a bunch of coils will appear on the screen?!"

Professor Huang's eyes narrowed slightly, and he felt something was wrong with what he said, but after thinking about it, there seemed to be no problem, so he nodded, "This kind of situation will indeed happen, and it is unavoidable, but when the screen lights up, Does not affect use."

"Oh,"

Chen Yang smiled, and asked again, "Aside from hardness and precision, what is the difference between capacitive screens and resistive screens in use?"

Professor Huang said, "It's mainly about hardness and precision. The only other thing is the operation method. Capacitive screens can be operated directly with fingers without special pressing. In addition, capacitive screens can support multi-touch. be weaker,

Oh, it’s not impossible, but a resistive screen that can support multi-touch will be very expensive, and it is not suitable for mobile phones. "

"Well," Chen Yang nodded, finally skipped the topic, and asked with a smile, "Then is this a feature phone or a smart phone?"

"It's just a functional phone,"

Seeing that the boss didn't bother with the screen any more, Professor Huang breathed a sigh of relief unconsciously, and said with a smile, "The current mainstream operating systems for smartphones are mainly Logia's Symbian, Blackberry's OS, and WP of Plague Fight. But Symbian and OS are basically used by themselves, rarely authorized externally, and only WP is used more externally, oh, I almost forgot, "

As he spoke, he patted his forehead and said with a smile, "There is also Apple's IOS, but I don't mention this, you know that Apple's system has always been closed-loop, and it is harder to get than Symbian and Blackberry.

In addition, the smart phone system is not ready to use after installation, but also needs to be adjusted and tested in all aspects of software and hardware. Therefore, I never thought about making a smart phone from the beginning. In addition, the current smart system ecology is not yet mature, but it has no functions If the machine is easy to use, it is better to concentrate on making a functional machine, which is more practical. "

Chen Yang glanced at him with a smile on his face, hiding his surprise well,

Normally, an expert and professor like him should be keen on the research and development of new technologies. I didn't expect him to do the opposite, emphasizing the use of mature technologies. It seems that his style is not right.

At this time, Professor Huang adjusted his glasses again, and said with emotion, "Actually, I also want to do research and development of smart phones, but the company currently does not have the conditions to launch the project in terms of technology and R&D talents. When the time is right, I suggest that the company can use smartphones as a key research and development project, which is of great significance both in terms of technology accumulation and market prospects!"

Of course, it is impossible for Chen Yang to object to such a suggestion, he nodded with a smile and said, "Yes."

After a pause, he smiled again, "Actually, Professor Huang, you can start preparing now. The foundation of technology lies in talents. UU reading "

He looked around and said with a smile, "Isn't there good conditions here? Let's use it first. Even if the Damai Technology Building is opened in the future, it will continue to be used here. If you need equipment, just spend money to buy it." , even if you spend money on it, you have to invest in a first-class mobile phone research and development center in China!"

Hearing this, Professor Huang immediately beamed with joy, "Okay, okay, if you have Mr. Chen's words, then I will let go and do it!"

Although he has the title of R&D director, he is just a newcomer after all. He is not uncommon for bosses who talk generously and are actually stingy. He has just joined the company not long ago, so naturally he dare not make mistakes casually, so when doing R&D, It also focuses on conservative schemes in pursuit of benefits,

But now that the boss has repeatedly said this in public, he can try to take a step forward and see how he responds.

At this time, Huang Shan also smiled and said, "Old Huang, just do it, we want money to give money, we want people to give, and we will definitely be your most solid backing!"

Well, with the two bosses speaking, Professor Huang felt more at ease, and began to think about the next development plan of the R&D department.
