Rewriting the Technological Scenario

Chapter 663 OLED screen hidden

On August 5, ZTE was coming.

The medium-sized model of the model is called a brand of huge models. ZTE has not disappointed this time. One launch will introduce ZTE V series, Q series, X series, Blade series, Open series five Series mobile phones.

This is also the style that ZTE has always maintained, and a conference does not take out three series of guarantees as if you can't afford the user.

As of now, ZTE has launched 15 series, and it is currently the most smartphone brands. At the beginning, everyone feels very chaotic, but slowly starts to accept ZTE "people", and every time I possess I look forward to how many new models that ZTE can come up again.

This five series mobile phones are from 599 to 1999, which basically covers the main price of low-end mobile phones.

Where the Blade series and the Open series are the Hongmeng processor, one is M3 one is M2, and the remaining high-pass processors.

The system is 10,000 elephants, while Samsung is most concerned about the screen. The result screen is all LCD screens, which is afraid that it is a high-end machine to use AMOLED screen.

However, Samsung does not find a special place, that is, the medium-end Mid-range machine and medium-sized machine use of wind Sony Optoelectronics LCD screen.

Great wind Sony Optoelectronics, is a very mysterious company established by the Great Breene Group in 2008, and the company has 50% of the company, and it is very low in the establishment. It is simple to accept the screen to further drive the screen. Technological development.

After that, I didn't have no longer appeared again, as if I have never had such a company in this world, until 2 years later, everyone finally heard the name of this company again, many people said it.

This time Li Yun is sensitive to what.

For a while, Meizu, Cool, Jin Li and other enterprises held their own conferences, basically introduced three mobile phones, and the price is about five or six hundred to two thousand.

The common point of this batch of mobile phones lies that the low-end machine is basically the LCD screen of the Great Breeze Group, and the medium and high-end machines are basically the high wind Sony Optoelectronics LCD screen.

There is also a common point in that Huaxia mobile phone manufacturers began to accelerate the foreign rush. This time, it is not for the market in China, but for the global market.

Over time, when more and more users from the world, a topic is gradually hot.

Especially for Huawei's conference at the end of August, Huawei directly uncovered this topic in the friendship.

Huawei launched three series of glory, glory youth, and Nova, and in the friendship, Huawei directly displays Samsung's SuperaMoled screen.

"We can see that Samsung Galaxys will display unevenness and bias, and there are many Samsung users in the latest time.

In fact, from the principle, it is because Samsung Galaxys uses DC dimming, but in fact, OLED screen and DC dimming are not fully fitted.

DC dimming is suitable for matching the LCD screen. "

Huawei directly name Samsung, making the Samsung screen after the conference, there is a problem in this feature.

In fact, the Samsung Galaxys has this screen problem, but the Samsung's brand is in that, Samsung is the leader of AMOLED, even a similar opponent, although there is a flaw, it is not so obvious, users also Not very clear.

After waiting for two years, the AMOLED screen began popularization, and the user was more and more focused on the screen.

But this Samsung has a strong wind group, this competitor, and even mixed the wind group is followers. At this time, you can don't be very fooled.

After all, in order to compete with the wind group Samsung every day, Samsung said that SuperaMoled is better than the ultimate screen. Every day, SUPERAMOLED is the top screen. Since you know the top, then you can't blame people.

Samsung Electronics held a meeting.

"SUPERAMOLED problem, why doesn't you seem to?" When Li Yun, when he saw the netizens pointed out that the Samsung screen problem, the first reaction naturally thought of seeing everyone's view to the extreme screen.

As a result, everyone said that there is no problem with the extreme screen.

"We read the introduction of the extreme screen, the PWM dimming of the extreme screen."

"PWM dimming?"

"Since theoretically, the OLED has a self-illuminating characteristic, if the voltage is lowered, it can even be lit, so the most practical way may still be PWM dimming."

"Then why do you choose to use DC dimming?"

"The theory is just theory ..." R & D personnel also said that it is very helpless. "Many theories are originally to accept market inspections.

In addition to the wind group, this world has never seen any company follows the mounting without market inspection, it can always know the market.

Moreover, we also found problems when studying PWM dimming. "

"what is the problem?"

"Although in theory, we can control the PWM dimming flash frequency within 400 Hz, which should be harmless to the human body.

However, in the process of our experiment, it is not comfortable, especially for visually sensitive people, and although there is no theoretical basis to prove that such frequency will be harmful to the human body, the phenomenon that can be tired Not rare.

So we gave up the direction of PWM dimming. "

Li Yunyu immediately asked, "That should have a user who feels uncomfortable after using the extreme screen?"

"Yes, I can really see this thing online."

Li Yunyu can't help but frown, "So PWM dimming this direction is also wrong?"

"This, see how companies have dealt"

"What do you mean?" Li Runwa's appearance.

"Although some people are saying that the ultimate screen is tired, but more people don't mind, because the wind group has made a very important thing, telling the words in front.

Hong Meng 4's instruction manual and the user code of Hongmeng 4 directly mentioned this problem. According to IEEEPAR1789 description, low-risk affecting the human health PWM dimming flash frequency should at least 1250 Hz, basically not affect human health. The PWM dimming flash frequency should be over 3000 Hz.

However, the OLED screen PWM dimming flash of the Hongmeng mobile phone is only 300 Hz, which is much lower than the wellness allowed in the IEEE document.

However, IEEEPAR1789 is to illuminate light source, but whether it is a lighting source or a screen source, it is an essential thing, so this thing is really hard to say.

It can only be said that there is no accurate theory that can support the OLED screen is harmful to the human eye. Even so, the Great Breeze Group is actively proposed that some sensitive people encountered in the experiment will not be uncomfortable to the OLED screen, remind users that if some discomfort can choose to return during the return period.

In addition, in order to avoid the damage of the mobile phone, Hong Meng 4 has a lot of reminders. For example, the mobile phone uses more than 2 hours, the phone will take a rest reminder, when the user uses the mobile phone, the phone will remind the user to use it best to turn on the light. In addition, when the user tunes the brightness, Hong Meng 4 will also remind to avoid using a mobile phone for a long time, because PWM dimming is more serious in low brightness.

You know, most users are actually not sensitive to this thing, you don't say, he didn't feel it at all, but the wind group still chose, putting an unconfirmed risk but is indeed a hidden thing, this Little is very smart. "

At this time, Samsung feels that the wind group is smart, but the Samsung as an OLED can also do this but don't do it.

The Samsung, who once killed theory, is harmless. I don't know this. It's like this person. It is a few users who are sensitive to screen. Most users have no feelings, and even some non-sensitive users, you put LCDs. The screen and the OLED screen are in front of him, he doesn't feel any difference.

So this is a small range that does not have theoretical support. It is said that this thing is in turn, and there will be some users who have worrying the OLED screen injury eye choosing the LCD screen mobile phone, affecting the sales of their own sales Samsung Do it.

But Meng Qian is willing to do this, because Meng Qian always believes that the user has a brain, there is a judgment, you will clear what you will know from the beginning, they will judge.

And even if this is the lack of OLED, the advantage of OLED is also very obvious, give the right to the user, let them do itself.

In the end, the most important reason for mobile phone injury is still because it is too long.

In the face of Meng Qian's "self-explosion" behavior, Samsung will take the pole screen without any way, can only find way to handle the public relations issue of SuperaMoled.

At this time, the wind Sony Optoelectronics suddenly said to open a conference.
