Description:

A black matrix (BM) made of Ytterbium nanoparticles (Yb NPs) is patterned directly on the cathode using cathode patterning materials (CPMs). The CPM-Seed and CPM materials ensure high transmittance and low absorption, maintaining display brightness and efficiency. This approach minimizes the gap between the BM and cathode, improving contrast, viewing angles, and optical performance, offering a new solution for advancing the Color Filter on Encapsulation (COE) technology.
