The interview with Yu Ping was surprisingly smooth, and they went through all the processes inside and outside the Bird's Nest except for the scrolls that needed the LED display. Pen & Fun & Pavilion www.biquge.info

Every time he arrives at a process, Yu Ping will talk to Leyuan about a large number of technical difficulties, and then ask Leyuan whether the technology of Leyuan Star Company can solve these difficulties, and Leyuan of course gave a positive answer one by one.

In fact, of course, Yu Ping knows that Star Company can solve these technical difficulties, just from the LED runway that Star Company built for Nike. What Yu Ping really wants to hear is whether Star can perform better on the basis of solving these technical difficulties.

If this is not the case, the previously proposed effect, you can find other companies to make LED displays, why bother to find Leyuan?

Finally, they walked to the center of the bird's nest, and Yu Ping pointed to the ground and said, "During the opening ceremony, there will be a large LED display screen here to display a large picture, which is 147 meters long and 27 meters wide.

And in addition to this, two cylindrical shaped LED displays are required, the diameter of this cylinder is about two meters, and the length is 27 meters.

In fact, the spacing of the screen is not the most important, the important thing is that the LED display spread on the ground must be waterproof and able to withstand the stepping of the actors. ”

Leyuan nodded thoughtfully and asked Yu Pingdao, "Do all the 127 by 22 display ranges use LED displays?"

Yu Ping wondered, "Hmm, what else can you use without an LED display?"

Leyuan shook his head, "Nothing, I'll be sure." ”

In fact, the answer that Leyuan wanted, Yu Ping's doubts had already answered him. In the last life, there were actually different theories about the scrolls of the Yenching Olympics.

Some say that the entire scroll is made up of LED displays, but there is another way of saying that only the middle one is an LED display, and the rest of the places are assisted by pani lights.

At that time, on this issue, Leyuan also deliberately revisited the clip where the scroll appeared several times, but because the picture was switched and the lens was too far away, Leyuan did not find very strong evidence from the video to explain what the structure of the scroll was.

Only in the later show, when the reel was full of actors, Leyuan felt that it was more likely that the entire reel was LED.

Because the actors standing on both sides do not have the light and shadow projected by the Pani lamp.

The pani lamp is a kind of projector, which needs another light source to emit light and shadow and project it onto the ground to form a picture.

Just like the projector used in a movie theater, if something or someone is blocked between the light source and the display area, the light and shadow will be blocked by the thing or person in the middle, making the display area appear shadowy.

And the reel in the video at that time did not appear in this case, so Leyuan felt that it should be more likely to be full LED, and Yu Ping's reaction just now also illustrated a point.

After determining this problem, Leyuan said, "Team Leader Yu, the few requirements you said can be solved by Star Company, but there is one problem, have you ever thought about it, that is, the power supply problem of the LED display." Such a large LED display, the amount of power required must be huge, and according to your design, it is definitely impossible to connect to the external power supply, so you must install a battery under the LED display. ”

Yu Ping frowned, of course their technical team had thought of this question, the opening ceremony of the Olympic Games lasted for several hours, although the LED display was not always on, but the power required was also very huge.

He nodded, "The problem you mentioned, we are contacting the battery manufacturer, and we should be able to solve it." ”

Leyuan raised his eyebrows, "Have you already contacted us, if it is not confirmed, I think our company can package them and solve them together." ”

"Your company, also have batteries?"

Leyuan nodded indifferently, "Well, it's still in the research and development stage, but it shouldn't be a problem to solve the power supply problem of this LED display." ”

Yu Ping took the design drawing in his hand and walked back and forth on the runway a few times, probably thinking about something.

Leyuan saw that he was thinking about things, but he didn't bother, and began to observe the internal structure of his nest at will.

Although it has not been completed, the interior has been completed, including the steel frame structure above, and there are some details that can be seen to have been done.

"Mr. Le," Yu Ping finally finished thinking, he said with some words to say, "I won't tell you, not only the battery, including the LED display screen, Director Zhang found a company at the beginning of the year, but because their progress is too slow, Director Zhang is afraid of problems, so they came to you, and now the battery thing is ......."

Yu Ping didn't finish speaking, but Leyuan already knew the general meaning, and it turned out that they were just second-hand preparations.

Director Zhang in Yu Ping's mouth, of course Leyuan knows who it is, Director Zhang Yimou and Director Zhang Da, he took over the chief director of the opening ceremony of the Olympic Games, which is a household name.

Yu Ping's words can actually analyze two meanings, first, in fact, on the LED display, the official must be biased towards cooperating with the star company, otherwise Yu Ping would not have said this when Leyuan proposed to contract the battery, and it should have been clear that he still had a competitor.

Second, the battery matter should not consider the star company, and the battery company that I contacted before should have been able to solve the problem of power storage. Or, they are not looking for a private company at all, but a state agency.

If it is really a state agency, Leyuan has no intention of fighting, it is of little significance, and it may offend people.

However, there are some things that Leyuan should mention still to be raised, and he said to Ping slowly, "Team Leader Yu, I brought up the matter of the battery, not to get business for myself, but I'm afraid that you can't find a company to solve this problem." ”

"Hehe," Yu Ping laughed, "This Mr. Le will rest assured, the other party has made it clear that there is no problem, and the battery will be made by the end of this year." ”

Leyuan also laughed, "That's good, I'm worried about the redundancy, but you must tell the other party that we are using the P1.6 display this time, and the power needed is not comparable to the power required by P10, which is an exponential increase." ”

"Exponentially ......"

Leyuan nodded, "Doubled, about six times, that is to say, the performance of the battery should be improved by six times on the basis of the original." ”

Yu Ping was completely stunned, although he was the leader of the technical group, but he really didn't know about the LED display, it was indeed a battery according to P10 before, but now after Leyuan said this, he knew what he had ignored.

After thinking for a while, Yu Ping said: "Mr. Le, I still have to communicate with Director Zhang about this matter." ”

Le Yuan smiled and walked out, "It's not too early, let's wait for our company's technicians to come over and study the details." ”

Yu Ping nodded and walked out, but when he saw the back of Leyuan in front of him, he still felt a little strange, but he just couldn't figure out what was wrong.
