Optimizing OLED Pixel Structures for Consistently Low Ambient Light Reflection over Viewing Angles

Achieving low ambient light reflection is essential for OLED displays. However, inevitable surface undulation associated with pixel structures naturally induces scattering reflection over larger viewing angles, even with circular polarizers. This work reports optimized designs of OLED pixel structures for minimizing such scattering reflection and for achieving consistently low ambient light reflection over angles and enhanced viewing experiences.
