Rebirth of Northern Technology

In April 1991,

Georgia became independent from the Soviet Union. Gulf War: The UN Security Council officially declared a ceasefire.

————————

LED production line 1.0, under the idea that people can conquer the sky, the completion speed is still very fast. The L manual production line of Optoelectronics was quickly put into use.

Most of the equipment in this production line is partially modified using existing laboratory equipment. In some process positions, the result of the fixture design may be wrong, resulting in unsatisfactory results. But this kind of thing can be changed even if it is changed, and it can be improved while producing. The purpose of this production line is to verify the concept!

This kind of forcibly launching the manual production line without waiting for the equipment made the Philip staff who came to visit dumbfounded.

With the joining of Wang Qingshan, Cheng Yongxing also temporarily escaped from LED performance improvement and equipment design. Considering things other than LED production, that is the design and manufacturing of large-screen LEDs.

————————

The front line of optoelectronic scientific research is also getting longer and longer. After a period of time, business should be split once, and then each business unit is responsible for its own business.

Under this idea, Cheng Yongxing formed a R&D and production team for LED large screens in addition to the LED production team.

The large LED screen is, strictly speaking, a downstream product of LED, which has its own rules of the game. For example, real-time signal processing, power supply voltage conversion.

In addition, it also has its own unique process requirements, such as how LEDs are lapped together and how to be modularized to facilitate installation, maintenance, and transportation.

Another batch of new technological processes and equipment are in front of our eyes.

Cheng Yongxing is not a superman, it is impossible to cover the world with everything, and the technical difficulty of this large-screen LED is not that great. Therefore, this part of the work will be completed by outsourcing.

This outsourcing task includes a series of development and production tasks such as modules, sub-circuit boards, main circuit boards and signal converters.

The optoelectronic research projects are already very famous. Several related cooperation projects have been well received. In the process of cooperating with optoelectronic scientific research, the various departments are basically fame and fortune. Therefore, the optoelectronic research projects are the best choice in the eyes of all departments.

After the plan was widely publicized, many requests for cooperation were fed back through various channels.

Due to some special reasons, Cheng Yongxing knows many more female classmates and female seniors. Or in other words, many female seniors know him! The typical figure here is Luo Weining.

The design of the circuit board, the design of the module and the issue of the signal conversion circuit board were hijacked by Luo Weining and transferred to the Department of Electronics. Several majors in the Department of Electronics have established corresponding research teams for research and development.

As a result, there is a group of close partners led by beautiful women in optoelectronic research.

These technical teams were later named as the Optoelectronic Beauty Corps, which contrasted with the technical core team of Optoelectronics Research, the Boy Scouts.

—————————

In the development of these peripheral devices, the agreement between the two parties was that the technical results were produced, and the results belonged to each department and specialty. Both property rights and economic benefits are shared. The initial development cost is paid by Optoelectronics Research.

This cooperation mode is also a common mode for optoelectronic scientific research outsourcing projects. These non-core technologies, more sharing, can fully mobilize the enthusiasm of partners.

The LED module is very simple, the initial design uses a 40x30 array. Such a large screen probably needs 342 modules to form a complete 720x570 resolution screen.

In order to reduce costs, the research team has developed a set of low-resolution modules. Each module is 24x19 and requires 255 modules. The appearance size of the two color screens is 4 meters x 3 meters.

The cost of the first large-screen LED was very high. One reason was that the waste of raw materials was very obvious because of manual manufacturing. Another reason is the lack of precision of the core equipment, the lithography machine.

When the formal production line is fully completed, this situation will change significantly. But even so, in this era, a full-resolution large screen requires LED manufacturing costs to reach more than 500,000. For low-resolution models, the LED cost is at least 120,000 yuan.

Of course, as output increases, some consumption in the production process can continue to decline. In addition, the price of raw materials should also drop significantly, and the profit margins of products will continue to expand.

—————————

In terms of company operations.

The total number of employees in optoelectronic research is slowly increasing, and departments such as procurement and production have been established successively.

With the gradual spread of the news of LED technology breakthroughs, more and more companies from outside the field are also preparing to enter this field, starting to contact optoelectronic research and seeking patent authorization.

But these are not short-term considerations for Optoelectronics. The current LED market is almost monopolized by several patent alliance members, and everyone does not want new players to enter the market.

—————————

Preparations for the production of LED modules have slowly begun. The third floor of Daqiao Shopping Mall is already under renovation.

But always renting a house like this is not a matter. The company then began the stage of large-scale construction.

The wealthy photovoltaic research company, while choosing a site to build a factory, bought a piece of land on the west side of the school to build its first staff dormitory.

The current construction cost is two to three hundred yuan per square meter. It is calculated based on 60 square meters for each apartment type and 48 households in a building. The cost of a building is only more than 900,000, and the synthetic dollar is only a matter of 100,000 US dollars.

At this time, there is no land sale. Through the relationship between the school, the photoelectric company purchased an idle warehouse of a railway subsidiary company, applied for a change of use, and built a staff dormitory.

The warehouse is not far from the school. It takes about 20 minutes to walk from the west gate, and it is very close by bike. It's a little regrettable that the location is a bit off. There is a small machinery factory next to it. The exit is almost blocked. When you go out and enter, you have to walk a half circle around the wall of this factory.

The warehouse and yard look quite big. If you build a house close to the existing boundary and work hard, you can build 5 houses.

Thinking well, when it comes time to find someone to help design. The teacher of the University of Architecture said that this land was built with two buildings at most, and there was a lot of talk about the passage and fire prevention.

This is the end of the matter and I can't regret it, so I have to build a building before talking about it.

Residential buildings in this era are mostly the same, with matchboxes measuring about 50 square meters. Cheng Yongxing didn't like these layouts, so he did it himself and designed two apartment types, one is a 60 square meter household type. There is also a single apartment of 30 square meters.
