Smic CEO Liang Mengsong has said that SMIC's \"28nm, 14nm, 12nm and N1 technologies have entered large-scale mass production, and the development of 7nm technology has been completed, and it can immediately enter risky mass production next April.\" This means that the domestic chip foundry industry can support OLED driver chip foundry.
However, this does not mean that OLED driver chips developed by domestic manufacturers can achieve mass production.
In fact, because different products need different sizes of OLED screens, so each OLED driver chip needs to be customized, chip foundries can not large-scale production, obtain low profits, so many foundries are unwilling to accept orders.
In addition, according to industry sources, the current domestic OLED driver chip is not without, such as Yingtang Zhikong, Yi Siwei and other companies as early as 2016 to develop domestic OLED driver chip. However, because the domestic OLED driver chip is not mature enough in design, manufacturers dare not use it in high-end products.
Not only that, according to the latest news reports, Huawei Hisilx's self-developed OLED driver chip faces difficulties in obtaining 40nm process closed test capacity and high-end chip test support.
