On October 27, 1980, after a year of construction, Li Yixuan's first OLED factory was finally completed and began to enter the mass production stage, and the patents related to OLED were also approved.

Looking at the stacks of patent books, Li Yixuan, who was sitting in the chair, let out a sigh of relief, and now he can throw off his arms and do it.

OLED is an organic light-emitting diode, English name organic light-emitting diode, abbreviated as OLED. Using organic polymeric materials as semiconductor materials in light-emitting diodes, ultra-thin film technology is used, with transparent conductive film as the anode, Alq3 as the light-emitting layer, triarylamine as the hole transport layer, and Mg/Ag alloy as the cathode, and the double-layer organic light-emitting device is fabricated.

OLED sounds high-end, but its history dates back to pre-liberation.

In 1947, Hong Kong-born Chinese-American professor Deng Qingyun discovered organic light-emitting diodes, that is, OLEDs, in the laboratory, and launched research on OLEDs, so Professor Deng is also known as the "father of OLEDs".

OLED is divided into two major technical systems, one is Japan, South Korea, and Taiwan low molecular screen technology, which is the AMOLED screen we are most familiar with, and the other is the polymer screen technology mainly concentrated in Europe, PMOLED screen, referred to as PLED.

Compared with the two technical systems, PMOLED has the advantages of simple structure and low cost, but the disadvantage is that it is difficult to make a large size technology, and in order to maintain the brightness of the entire panel, it is necessary to increase the brightness of each pixel and increase the operating current, which will reduce the life of the OLED device.

At the same time, PMOLED can only achieve monochrome display, and it is difficult to achieve color display, even if it is realized, the saturation, richness, contrast and brightness of the color cannot be compared with AMOLED.

PMOLED is like NT and SNT liquid crystals.

AMOLED is equivalent to TFT liquid crystal, its true color, size can be large or small, more power-saving, high resolution, longer panel life, data driver design is simpler. The disadvantage is that the process is more complex and the TFT variability is high.

Li Yixuan's production line belongs to the PMOLED system, which is completely enough as the screen of the "China Cube" machine, and he will only go to the AMOLED screen when he wants to go to the real handheld.

At that time, he will not eliminate the PMOLED line, which can be used as a display screen for daily household appliances, such as rice cookers, range hoods, water heaters, electric fans, electric razors and other white goods and small household appliances.

In the future, the LCD screen market is huge, not only mobile phones, computer monitors and TVs, including all kinds of small household appliances, if there is no LCD screen on it, it will be very unpopular.

Press an LCD screen on household appliances, and the forcing of electrical products will be improved.

The electrical appliance is pressed on a large screen, even if the functions of the product are the same, it will also give consumers a sense of high-end atmosphere and grade.

If the LCD screen on the appliance is not only large, but also OLED, it can be called the most cutting-edge technology product, and it is properly equipped with a sharp weapon.

Li Yixuan's "China Cube" machine is actually the famous "Tetris Machine" in history, which is the predecessor of the famous GB handheld series.

Historically, after Nintendo bought out the rights to the block game, it did not initially move it to the handheld platform, but sold it as a home console game. It wasn't until '89 that the game was moved to the GameBoy handheld platform.

Why did it take so long, because with the chip manufacturing process technology at that time, it was not possible to make "Tetris" on the handheld.

In the 80s, if you wanted to make a handheld game console, you would face several major technical difficulties.

First, when there were no energy-efficient CPUs and GPUs for handhelds and mobile phones, ARM was not yet born, and its predecessor, Acorn Computer Company, was still racking its brains for CPUs on the next generation of Acorn desktop educational computers. GPU has no such statement, at that time, the handheld was still used on the portable computer, the performance was very limited, and the first condition of the handheld could not be realized.

The second is that the NT LCD process at that time was not mature, and the screen could not be made bigger, so it could only be used as a display screen for electronic watches and portable calculators.

The third restriction is cassette technology, due to the size of the handheld, the cassette that has been used by the game carrier, and the capacity and price of the memory chip on the cassette determine the popularity of the handheld.

The handheld cassette is different from the general host cassette, because the handheld is battery-powered, the memory chip on the cassette must first consider energy saving, if the host cassette chip is directly used, the battery is not moving.

Handheld cartridges generally use flash memory chips, which are the same type of memory chips on our mobile phones.

You must know that by 82 years, the storage core discharging capacity has just exceeded 128K, which is still used on the host cartridge, and flash memory technology has not yet appeared, if DARM is to be used normally on the handheld, the storage capacity will often be sacrificed, and slightly larger games cannot be installed.

As a result, the handheld was born in the 90s instead of the 80s. Because with the semiconductor chip process technology in the 80s, it is not possible to make memory chips with a capacity of more than 1M.

Even if Li Yixuan is a traverser, he can't increase the capacity of the memory without improving the memory chip process.

But he is a traverser after all, and he has his own way to take out the flash memory technology in advance.

Anyone who has studied computer science knows that memory is divided into primary memory and external memory. The main memory is the memory, which is used to temporarily store random data, and the data disappears when the power is off, while the external memory is the hard disk, and the data can be retained permanently.

The same is true for flash memory technology, which is divided into two categories: NOR type and NAND type. The former is used as the memory of the mobile phone, the latter can be used as the hard disk of the mobile phone, and the other FC card, SD card, U disk, etc. are all NAND flash memory, which has the advantages of low cost and large capacity.

Li Yixuan's plan is to make him into a cube machine and sell it on the market first, and after a few years, the chip manufacturing process will progress to below 1 micron, and he can launch a real handheld machine.

In December 1980, Li Yixuan came to Taipei again, this time to inspect the production of the "China Cube" machine.

Since Guo Taiming got the sample of the "China Cube" machine, Octavia's market insight realized that this little thing was backfired. Therefore, after signing the OEM contract with Li Yixuan, Guo Taiming directly lived in the factory, ate and lived with the workers, and supervised the production of the "China Cube" handheld.

The factory used to produce handheld computers is the steel structure workshop that Li Yixuan helped him build last year.

Walking into the production area, I saw a handheld machine coming down from the assembly line and being sent to the packaging workshop next to it.

Li Yixuan picked up the finished handheld that had just come off the assembly line, installed the battery, and said: "Yes, it has fully met the design requirements, how much can your monthly production capacity reach now?"

"The current monthly production capacity can reach 50,000 units, and my workers are fully skilled, as long as your chip and LCD panel supply is sufficient, the monthly production capacity can be increased to 100,000 units at any time. Terry Gou replied.

"No, the production capacity has to continue to increase. Li Yixuan shook his head and denied: "Our chip and LCD panel production lines have all been debugged, the monthly production capacity has exceeded 300,000, the new production line has been stationed, and the monthly production capacity will exceed 1 million in the future, you have to continue to improve." ”

"With such a high output, can you sell it?" Guo Taiming was surprised. What is the concept of a monthly output of 1 million? It is an annual output of 12 million, such a large shipment, he seriously doubts whether the market can digest it.

"Don't worry, you can eat as much as the market. Li Yixuan said indifferently.

You must know that Nintendo's "Tetris" handheld has sold more than 200 million units in history, and this does not include pirated handhelds. If you count this part, Tetris definitely has more than 1 billion players.

And Li Yixuan sold the "China Cube" handheld more than eight years in advance, so he is naturally confident that he will sell better results......

The only thing that worries him is capacity.

"It takes time. Guo Taiming is full of bitterness.

Oranges is Foxconn's largest customer, and 80% of the factory's production capacity is used for Oranges products. In order to meet the order requirements of Oranges, Terry Gou has been building factories in recent years.

But he found that no matter how many factories he built and how much production capacity he provided, Oranges could eat it.

Now that Li Yixuan has put forward such a large production capacity request, Guo Taiming really can't think of any other tricks for a while.

After all, even if the construction speed of the steel structure workshop is fast, it will take several months, it is impossible to build it in one day, plus the early stage of land, planning and later equipment procurement, commissioning, worker training to be fully proficient, how to take more than a year, production capacity can not be raised in a short period of time, not to mention such a large production capacity, just the recruitment of workers will have to tens of thousands.

"What if you provide the production molds and let your brother's mainland factories join in?" Li Yixuan knows that the reason why Foxconn can become the top OEM company in the world is because of the unique mold opening technology.

Mold opening technology is the foundation of Guo Taiming's life, Li Yixuan will not be stupid enough to let the other party take out this technology, just let him provide the mold, let Guo Taiqiang's Zhengwei enterprises add in.

"Yes!" Guo Taiming finally agreed, after all, he is his younger brother, and they are all a family.

To increase production capacity, more factories need to be built, and capital is needed. Guo Taiming did not mention the acquisition of Foxconn shares from Li Yixuan, and Li Yixuan also pretended not to know, after all, the more the shares are held in his own hands, the more one day the appreciation will be. He will be able to sell the shares for a good price in the future.

After the negotiations, Li Yixuan stayed for another two days before returning to Hong Kong.
