- Tunghsu Optoelectronic Technology Co., Ltd. (000413.SZ) engages in the research, development, production, and sale of optoelectronic display materials and related products primarily in China. The company offers core products and services including rare earth phosphors for plasma display panels (PDPs), field emission displays (FEDs), and vacuum fluorescent displays (VFDs); indium tin oxide (ITO) conductive films; electronic pastes such as silver pastes, dielectric pastes, and black pastes; color filters; and LED packaging materials, serving the display panel manufacturing and optoelectronics industries with a focus on high-end materials for large-size screens and energy-efficient lighting. Headquartered in Guiyang, Guizhou province, the company was founded in 1995 and operates mainly within China, with production facilities and R&D centers concentrated in the domestic market targeting electronics manufacturers and display producers.
In recent developments within the last 1-2 years, Tunghsu Optoelectronic has expanded its strategic partnerships, including collaborations with leading display panel makers for advanced phosphor and conductive film technologies; pursued funding for next-generation mini-LED and micro-LED materials R&D; and launched new product lines in quantum dot films and high-conductivity ITO targets to capitalize on the shift toward OLED and QLED displays. The company has also undertaken operational enhancements, such as capacity expansions at its Guiyang base and investments in green manufacturing processes to meet stringent environmental standards. No major name changes or reorganizations have been reported recently, but Tunghsu continues to strengthen its position in the optoelectronics segment amid China's push for semiconductor self-sufficiency.
