In fact, mobile phones before 2017 were all packaged in COG, so they all had big foreheads and big chins.

Being able to create a Xiaomi Mix with no forehead and ultra-narrow chin is already the limit. For this reason, the camera has to be placed in the lower right corner.

If you want to achieve a next-generation full-screen display with an ultra-narrow forehead like the Samsung S9, which is narrower than the ultra-narrow chin, you need to develop the next-generation COF packaging technology, which is flip-chip film packaging technology.

The punch-hole screen must at least use COF packaging technology.

In the previous life, COF packaging technology only appeared in 2017.

Samsung ix2 uses COF packaging technology to achieve a higher screen-to-body ratio.

If you want to achieve a 100% screen-to-body ratio and a full screen, you need COP packaging technology.

And COP can only be used for OLED screens, not LCD screens.

Such as iPhone x!

In response, Wang Yi looked at Zhu Changlin: "Lao Zhu, continue to recruit talents, poach people, and do your best to develop COF packaging technology."

COP is more advanced, but cannot be used for LCD screens.

At a time when LCD screens are the mainstay, COF is more practical, easier to develop, and cheaper.

Cost:COG < COF < COP.

Screen-to-body ratio/advanced level: COG < COF < COP.

"Okay!" Zhu Changlin responded.

But unfortunately, even if Wang Yi invests heavily in research and development in advance, it will still take time to make a breakthrough.

"How to maximize the possibility of achieving a full screen without a breakthrough in the packaging process, and the camera is not in the lower right corner." Wang Yi fell into deep thought.

Zhu Changlin also had no idea.

This requirement is somewhat harsh.

Without breakthroughs in packaging technology, it is impossible to achieve a 100% screen-to-body ratio, and the narrow chin cannot be removed.

For the sake of screen-to-body ratio, we can only remove the forehead and place the front camera on the narrow chin, so the lower right corner lens appears.

But many people don’t like the lower right corner lens, so if you continue to place it at the top of the screen, you have to keep the forehead.

With a chin and a forehead, the screen-to-body ratio is high.

This is difficult to correct.

But Wang Yi's eyes lit up: "Lifting camera!"

"???" Zhu Changlin was startled, and then suddenly realized: "Chairman, do you mean that the front camera continues to be above the screen, using a lift type, and is hidden inside the fuselage?"

Wang Yi nodded: "Yes, this way you can remove the forehead, super-narrow the chin, and achieve the first-generation full screen while still keeping the front camera at the top!"

"What a great idea, why didn't I think of it!" Zhu Changlin suddenly realized: "But the lifting camera needs to be developed. This year's Xphone 3 will be released in September. I'm afraid it will be too late."

Wang Yi nodded: "It's okay. The Xphone 3 is designed according to the conventional design, with an ultra-narrow forehead, an ultra-narrow chin, and the front camera at the top center. With the power of Kunpeng 902, it is enough to sell well."

"Xingyi Phone X1 can consider abandoning the lens on the lower right and changing it to a pop-up camera, but this requires abandoning the ceramic body and implementing side fingerprint unlocking!"

Wang Yi likes Xiaomi MIX’s full screen, ceramic body, and ceramic back shell, which is full of high-end feel.

But Xiaomi Mi Mix’s lower right corner lens and back fingerprint are just flaws.

Otherwise, the ceramic body is difficult to process, and it is unrealistic to put fingerprints on the entire side of the ceramic middle frame.

The side fingerprint keys are destined to be relatively wide. It would be too technically difficult to open such a wide hole in the ceramic middle frame. It was achieved within ten years.

Therefore, the Xiaomi Mi Mix series uses fingerprint recognition on the back, so there is nothing you can do about it.

To put it bluntly, ceramic body and side fingerprints cannot have both.

A full screen and a front fingerprint home button are also incompatible.

You need to think of everything, unless you create 3D structured light or under-screen fingerprints, or a hole-punch screen.

But it was impossible to do it in 2013, not even one.

All that can be done now is to make choices.

The Xphone 3 will be launched in five months, and it will be too late to lift the lens or fingerprint on the side.

It can only be made into a conventional design like the xphone 2pro, with the front lens in the center of the narrow forehead, and the front touch fingerprint unlocking on the narrow chin home button.

The Xingyi X1 can be released on New Year's Day, and there is still time for major changes. You can choose a metal body + lifting lens + side fingerprint.

Or choose ceramic body + lower right corner lens + back fingerprint.

There is no doubt that the lift lens + side fingerprint is definitely better than the lower right corner lens + back fingerprint.

But the texture of the all-ceramic body is better than that of the metal frame.

You can only choose one of the two.

After some tangle, Wang Yi chose to give up the all-ceramic body like Xiaomi Mix.

"Changlin, Xphone 3 has a decent design. It is equipped with Kunpeng 902, which is powerful enough."

"As for Xingyi X1, it uses a metal body + side fingerprint + pop-up camera."

"Are we going to give up on ceramic fuselages altogether?" Zhu Changlin asked.

Wang Yi sighed: "The large opening of the ceramic version is unrealistic. You have to use the lower right corner lens and the fingerprint on the back, which is a bit awkward. Moreover, the all-ceramic body is costly and difficult to process, and is not suitable for large-scale mass production. Let's put it aside for now."

.When the technology matures in the future, we will make a ceramic body."

"Yes, the production capacity of ceramic fuselage will not be high." Zhu Changlin agreed very much.

The simplest one, Xingyi Mobile Phone Factory, produces metal bodies and can produce 13.33 million units per month.

If we were to produce ceramic bodies, it would be difficult to produce 10 million units per month!

The processing difficulty of ceramic fuselage and the difficulty of drilling holes are much more difficult and troublesome than that of metal fuselage.

It is precisely for this reason that there are not many mobile phones with ceramic bodies, they are either niche or high-end, and the prices are very expensive.

In addition, the ceramic body requires fingerprints on the back and a lens in the lower right corner, which is too high on the hips. Wang Yi chose a metal body + lifting lens for the Xingyi Phone X1.

"Okay, Chairman, I will develop the Xphone 3 as soon as possible. It has a regular design and will not delay the release. The Xingyi X1 will have a metal body, side fingerprints, and a pop-up lens. It will probably be released later, probably around New Year's Day.

"

"Okay, let's adjust. Xingyi Mobile X1 will be released on New Year's Day. As the first innovative full-screen super flagship product in 2014, the price starts at 6,999."

"Unbounded note is adjusted to be released in November. Double Eleven will boost sales and take over the market of xphone 1 and xphone 1pro. By then, xphone 1 and xphone 1pro will be completely discontinued. It will take advantage of Double Eleven and Double Twelve to clear out all

in stock."

"This is the best arrangement." Zhu Changlin responded: "The only regret is that the ceramic mobile phone has to be moved back a little bit."

"The short delay is just to start better!" Wang Yixiao said.

When there are under-screen fingerprint scanners and hole-punch screens, ceramic phones will be launched in a big way, killing everyone everywhere.

But before that, you can only choose:

"However, the Xingyi mobile phone X1 on New Year's Day, in addition to the regular version with a metal middle frame + glass back shell, can also have a higher-end ceramic back shell version, using the same color metal middle frame + ceramic back shell, which is barely achievable.

A semi-ceramic phone!”

"This is great!" Zhu Changlin was excited: "The metal middle frame can be used for side fingerprints and lift-type cameras, and the ceramic back shell can also give play to the texture of ceramics."

“Although it’s not as good as an all-ceramic body, it’s still rare. And it’s made with a metal frame of the same color, so I’m afraid many consumers won’t be able to tell it’s a metal frame. It can definitely hit the higher end!”

Wang Yi nodded: "At that time, the standard full-screen version of Xingyi Mobile Phone X1 will start at 6,999, and the full-screen version with ceramic back shell will start at 7,999!"

The Porsche versions of several Huawei models in previous generations had metal bodies + ceramic back shells.

Moreover, a separate ceramic back shell is easy to produce. It is not as complicated as an all-ceramic body, and production capacity is more guaranteed.

"Let's arrange it this way!" Wang Yi sighed.

In order to solve the disadvantages of the lens in the lower right corner and fingerprints on the back, a lifting lens + side fingerprints were designed.

Before the emergence of under-screen fingerprint scanners and hole-punch screens, this was considered the best solution.

As for the under-screen fingerprint scanner, it is more difficult and requires time to develop.

Hole-digging screens require a breakthrough in packaging technology.

Due to the limitations of the times, Wang Yi could only compromise.

But even so, the Xingyi mobile phone X1 on New Year's Day next year, Kunpeng 902 SOC + full screen + pop-up camera + side fingerprint, is still an absolute king product.

Even if it starts at 6999, it will be completely sold out.

Even the ceramic back shell version of 7999 is a hot seller.

Without him, eliminating the bottom right corner lens will stop 30% of users from being resistant.

Side fingerprints will also solve the problem of users who don't like back fingerprints and worry about blurring the rear camera by touching fingerprints.

As for the side fingerprint on the right side, it is inconvenient to unlock...

The problem is that the lock screen keys of Apple and many Android phones are on the right side, and everyone can use them very easily...
