With the rapid development of mobile devices in recent years, the applications of the flexible touch phones, panels, and flexible laptops not only satisfy multiple needs with improved convenience but also result in the demand for high-end materials. Our film solutions are compatible with the MOI (Metal on ITO) equipment process while enabling cost reduction with the self-developed high sensitivity etchant and technological support. Bypassing 400,000 times of the bending tests (R = 1mm), our films have sensors with line and space reaching only one-third of the traditional narrow border sensors (L/S=10/10um), which successfully pushed the limits of the present specifications.
