It was not until a few years ago, in 2014 or 2015, that Huawei hisilicon's chips barely kept up with The Times, and Huawei used some of its own domestic chips in its products

After all, Huawei is a global strategy, has always been based on purchased chips, independent development replacement, in case of today's supply interruption, it will not be paralyzed, the recent US ban on Huawei, so that Huawei mobile phones officially began to turn to domestic chips, but it takes time, that is, until today, Huawei mobile phones still have a large part of the use of imported chips. The time needed to replace all Huawei mobile phones with domestic chips is calculated on an annual basis, and this matter cannot be rushed at once, we must be patient
Most of them are homegrown. Recently, the first international intelligent terminal development conference was held in Yibin, China Academy of Information and Communications Technology deputy chief engineer Shi Denian said that at present, our processor chip design capability has reached the world's leading level, the domestic mobile phone market chip localization rate is 23.6, and the proportion of domestic smart phone screens is 67.5%.
Among them, the domestic mobile phone processor refers to Hisilicon Kirin, while the mobile phone screen refers to BOE, Tianma, Vicinosa, Huaxing Optoelectronics and other manufacturers. Huawei and BOE recently reached a strategic cooperation agreement in Chongqing, and the two sides said they will further expand cooperation areas. With the continuous growth of Huawei mobile phones, it will also drive the faster progress of domestic mobile phone chips and domestic screens.
