When it comes to navigation hosts, this profit is very large, a complete set of navigation hosts, replaced in the 4S store in the previous life, at least tens of thousands of yuan, even 2, 30,000 is not unusual, even more outrageous I heard that there are 100,000.

This is in stark contrast to the aftermarket navigation host that costs thousands of yuan. Why would they buy it so expensive? It's all the same functional entertainment system, and the cost performance is too far apart, right?

Ye Kai used to be very curious, and he also had an in-depth understanding of the difference between the two, and there are roughly the following points that can prove the reason why people buy so expensive.

First of all, the navigation host in the front-loading market needs to perfectly match the ECU protocol of the original car, not only to send instructions to the ECU, but also to receive ECU information. For example, the analysis and display of air conditioning information and control, fuel consumption, vehicle speed, and even the data analysis and display of the odometer, and some can even control the lighting system.

Secondly, the navigation host in the front-loading market does not have the reset key of the after-installed navigation host, which makes the motherboard circuit of the navigation host more complex circuit design, longer aging test, and higher requirements for the selection of components.

After that, the car manufacturer has a very low failure rate requirement for the navigation host provided by the OEM, and if it exceeds the ruler line, it will not get money, but will lose money. Therefore, OEMs use the navigation host they manufacture, from design to component selection, as well as the grade of the circuit substrate, according to the best use. In this way, the cost naturally increases.

Finally, since it is an OEM, it is necessary for the OEM to produce the navigation host, which can only be supplied to the corresponding car factory, and must not be circulated in the market, otherwise it will be caught, there is no two words to say, two words: lose money.

Such a back and forth, coupled with the exclusive dealers of the car factory, 4S shop in the middle of the link in the continuous increase in price, the pre-installed market navigation host is not expensive to think of the price is impossible.

Not only that, as an OEM developer, it is also very cunning, if one of the car manufacturers provides the main engine, then the other car manufacturers, the circuit board of the host does not need to be redesigned, only need to replace the software and shell. Even some panels and the host are separated and provided by different companies, so they don't even bother to change the shell of the host, so they save R&D and production costs.

Therefore, if the OEM provides the main engine for more car manufacturers, then he earns more.

In addition to the joint venture company, Ye Kai's current car factory also has an Aaudi company that is about to be included in the bag, and at least one car factory in the future is already in Ye Kai's plan, in short, Ye Kai's idea is to try to take other people's paths, so that others don't say that there is no way out, at least they need to find another way.

After talking about the navigation host, then we have to talk about its display.

In the previous life, the display screen of the navigation host was a liquid crystal display, which is commonly known as a thin film field effect transistor liquid crystal display.

This is a display that evolved from the TNS LCD display and has been used for decades. It controls the opening and closing of the thin-film field-effect transistor by using the line field timing signal, so that the voltage representing the picture signal passes through the transistor and the liquid crystal molecule to the ground wire to form a loop, so that the liquid crystal molecule is deflected, and the backlight is deflected through the corresponding trichromatic filter and restored to a color image.

Although the picture of liquid crystal display is not as clear as the clarity, vividness and responsiveness of the glass picture tube, its thinness, compactness, large viewing area, and no radiation still make it quickly popular with people and enter thousands of households.

This is a huge market all over the world, so huge that people can't imagine, whoever goes first to occupy the mountain, who can call the wind and rain in this market, lead the trend, and establish a brand effect.

However, in the previous life, in this market that calls for wind and rain, the big brother who has been a big brother for many years still needs to turn around after 84 before he begins to turn around and develop this technology that makes them eat and make a lot of money.

And now Ye Kai wants to develop this technology in advance, which is not without heritage and advantages.

His background comes from Fairchild, because to produce LCD screens, you first need a lithography machine, which is different from the lithography machine produced by chips, although the principle is similar. However, with a slight improvement of the lithography machine that can make chips, it is possible to make an exposure machine for liquid crystal thin-film transistor circuits.

His advantage is that he knows the history of the development of LCD technology and various improvement technologies, and he only needs to follow the development direction of his previous life step by step, the only difference is that he will advance the time a little earlier.

As for the other components of the LCD screen, the chip factory that can provide chemical materials for the lithography machine must have chemical talents. The only thing that is needed is time.

For the research and development of LCD screens, Ye Kai thought about it and transferred people from Fairchild Company to set up separately. As for the navigation unit, oh, it should only be called a head unit now, because the only sound sources that can be used in the car are tapes and radios.

Therefore, the circuit structure is relatively simple, nothing more than a microprocessor, a magneto-electric conversion audio integration block, a radio module integrated with radio and demodulation, an electronic volume control integration block, a 4-channel power amplifier integration block and a digital liquid crystal display driver integration block, and other peripheral components constitute the audio host.

The only improvement was to replace the mechanical tape movements, which were now prevalent, with light-touch electric movements. The only big change was to wait for the development of its own 8cm CD portable player, and then combine the sound technology of simplified Bose and Harman Kardon to launch its own premium car audio system.

However, these technologies must be found as soon as possible to start research and development, because technology does not have its own golden finger, and can achieve a qualitative leap, or need to be developed step by step, so that the future can go further, and the R & D team will be more substantial.

Fortunately, the people in the R&D team are ready-made, that is, the Harman company that was sold by Harman Kardon because of its participation in politics has been dilapidated in the hands of the new owner, and the former R&D team must be panicked.

As for the acquisition, Ye Kai never thought that with the collapse of the Carter administration, Harman, who had withdrawn and left, would naturally turn around and buy back the company he once was. The current Ye Kai is still very weak, it is the best time for low-key development, and it is naturally not in Ye Kai's current interests to collide with Harman, who has a wide range of connections.

Although the previous Harman company was under the leadership of Harman, it was awesome in the audio market, but Ye Kai also knew that technology was still one thing, but Harman's connections were also one of the key factors that helped him become famous.
