According to media reports, Huawei HiSilicon has developed an OLED driver chip, which is expected to be produced by a domestic chip foundry in the 28nm or 40nm process as soon as next year. This move will break the monopoly of OLED driver chips by foreign companies. Huawei is currently facing difficult difficulties. It is undoubtedly admirable that it can still create another miracle.
Although Huawei is in a difficult situation, it will once again create chip miracles
China has created a miracle in the LCD panel industry. In more than 10 years, China has become the world's first from scratch. BOE and TCL Huaxing are the top two LCD panel companies in the world. With the development of China's LCD panel industry, South Korea Of panel companies chose to retreat from the LCD panel industry.
After retreating in the LCD panel industry, South Korean panel companies are now committed to consolidating their leading advantages in the OLED panel industry.Samsung has a market share of more than 70% in the small and medium-sized OLED panel market, and LGD has achieved more than 9% in the large-size OLED panel market. Market share.
Faced with the advantages of South Korean panel companies in the OLED panel industry, Chinese panel companies are catching up, among which BOE is undoubtedly the vanguard. At present, BOE has four small and medium-sized OLED panel production lines, and has achieved more than 10% market share in the global small and medium-sized OLED panel market, becoming a strong competitor of South Korea's Samsung.
However, the data provided by the media shows that OLED panel driver chips are mainly controlled by South Korean companies. China's self-produced OLED panel driver chips only occupy 1% of the market share. For this reason, BOE purchases more than 90% of OLED driver chips every year. Import.
Although Huawei is in a difficult situation, it will once again create chip miracles
In order to change the monopoly of OLED driver chips by foreign companies, Huawei HiSilicon has taken on the important task of changing this situation and developed an OLED driver chip, which is technically comparable to the OLED driver chip of Korean companies.
Huawei HiSilicon chose to develop OLED driver chips because this chip has relatively low requirements for chip manufacturing processes. It is reported that the most advanced technology used in OLED driver chips is only 28nm, and China's chip foundries have mature chip manufacturing processes. Among them, the 40nm process is about to be fully autonomous, and there is no need to look at the face of the United States.
Due to Huawei's experience since the second half of 2019, China's chip manufacturers and chip industry chain are working hard to promote the autonomy of chip manufacturing technology. It is reported that the 55nm process has achieved complete autonomy, and all parties are currently working together to promote 40nm and 28nm processes. According to Huawei’s plan to start production of OLED driver chips next year, it may mean that the 40nm process and 28nm process can be fully autonomous next year.
Although Huawei is in a difficult situation, it will once again create chip miracles
Huawei is currently facing huge difficulties. Its published performance in the first half of this year showed that its sales revenue was 320.4 billion yuan, a year-on-year decrease of 29%. In such difficult circumstances, it still keeps in mind its mission to develop independent chips and break the monopoly of foreign companies on OLED driver chips. The situation shows that this company is tenacious.
In addition to continuing to strengthen independent research and development in chips, Huawei is also actively expanding new businesses, developing 5G applications, smart cars and other businesses. Dilemma.
