It is confirmed that Huawei HiSilicon’s first self-developed OLED screen display driver chip has been taped out in 2020 and has entered the trial production stage. It is expected to be officially delivered to suppliers by the end of this year. Huawei’s own products are also expected use. Huawei confirmed to the outside world a few years ago that it will begin to deploy chip products in the OLED field in 2018, and has also established a related chip research and development department. According to public information, OLED display driver chips are difficult to manufacture, and they are specially customized according to the needs of the self-luminous characteristics of screen materials. Therefore, foundries cannot achieve mass production. OLED screen driver chips have been monopolized by giant companies such as South Korea's Samsung and LG, occupying 90% of the world's share, while TSMC has only 9%. At present, the OLED screen driver chips used in the market in my country have been dependent on overseas imports. Now that Huawei's self-developed OLED screen driver chip has succeeded, this unexpectedly relies heavily on South Korean companies' embarrassment is expected to be alleviated.
