Yunyinggu Technology (云英谷科技), which rebranded as Viewtrix Technology, is a Shenzhen-based fabless semiconductor company founded in 2012 that designs AMOLED display driver integrated circuits (DDIC) and color-rendering display solutions for smartphones and other devices. By 2024 sales volume it was the largest AMOLED display driver chip supplier in mainland China and the fifth-largest globally, with R&D and operations across Shenzhen, Shanghai, Beijing, and Hong Kong. Backed by Qiming Venture Partners (Series C and extension), Huawei, and Xiaomi, the company completed a Hong Kong IPO. It is a hardware/semiconductor business and publishes no public developer API surface; this profile is retained as a network identity record. The original yunyinggu.com domain no longer resolves and viewtrix.com is a parked domain-for-sale listing.
