What kind of mobile phone can pure domestic parts make? Just don't use foreign parts and patents?

If you don't rely on foreign parts, only rely on parts produced by your own technology, can you make a mobile phone? The answer may be unexpected. First of all, it needs to be clear that what is said here is the purely domestic part, not the lack of purely domestic technology, which is unrealistic. After all, GSM technology is also a standard formulated by the European Telecommunications Association. Without this standard, mobile phones may not be able to make calls. Therefore, it is not feasible to rely entirely on foreign technology.

Therefore, if we only talk about domestic independence, the answer is yes. With our current technology, we can make our own smart phones. Fundamentally speaking, what we criticize now is only the processor, screen, memory, camera and system. Take Huawei mate30 as an example. The processor is a HiSilicon processor independently developed by Huawei and produced by TSMC. The screen is provided by BOE and made in China.

Let's talk about hardware first. At present, there are some domestic processors, high-end Kirin, low-end pine cones and Spreadtrum. There are BOE and Tianma on the screen. The camera has a Yu Shun optical system; And the battery has Desai and so on; Fingerprint has a sink, and as for other components on the motherboard, domestic substitutes can generally be found; Shell is easier. At present, what is truly irreplaceable may be memory. After all, it seems that the memory of Ziguang really can't be used on mobile phones on a large scale, which is really helpless.

In fact, Huawei has not only made great achievements in mobile phones, but also made great breakthroughs in other scientific and technological fields. The ban on Huawei during this period also made us see Huawei's strength clearly. After Google announced the suspension of cooperation with Huawei, Huawei announced its independent development? HarmonyOS system? In fact, Huawei began to develop its own patented technology a long time ago, and after several years of continuous efforts, it finally achieved results.

The ISP, RF decoding, audio, charging and other chips in the mobile phone have all been replaced by purely domestic parts. It can be said that Huawei mate 30 series is currently the largest number of smartphones in China. But there are two key parts that are not made in China, one is the camera and the other is the flash memory chip.

Mate30' s camera sensor was jointly developed with Sony. Flash memory is provided by Samsung and Hynix. Can we find a family substitute? In fact, it can be provided by domestic enterprises such as Shenzhen Eurofilm Technology Co., Ltd., lt, Sunshine and Guangbao. Overhall technology, which we are familiar with, is the company with the strongest technical strength. This company first started in the United States, and was later acquired by China. It also has the same convenient technology on the camera.

Flash memory chips may not be optimistic. At present, the top three flash memory chip manufacturers in the world are Samsung, Hynix and MgO, accounting for more than 95% of the global flash memory market supply. However, with the breakthrough of flash memory technology by Ziguang and manufacturers, it is no longer a dream to break the original market monopoly of flash memory. Therefore, in terms of cameras and flash memory, even if they do not reach the world's top level, there is no problem in normal use. With the increase of R&D investment in Huawei and other manufacturers, we believe that these technological monopolies will be broken one by one.
