Lu Weibing stated that Xiaomi is the first domestic company to develop optical materials independently.

CCTV News' official Weibo account reported today on the Xiaomi REDMI K100 Pro series super pixel screen, stating that Chinese screen technology has achieved global breakthroughs. Xiaomi Group President Lu Weibing wrote, Xiaomi is the third global company and the first domestic company to self-develop from the light-emitting material layer. Our investment in screen technology is long-term and resolute. It is reported that last year, Xiaomi developed its own red primary material, and this year it has made breakthroughs in green primary material. The most critical part is that the fourth-generation pTSF is an innovative foundational display technology solution developed in China, which Xiaomi and the Tsinghua team brought to fruition over more than two years, transforming laboratory theory into final engineering mass production.
