Display Panel Hollow Area Reduces Reflectivity

The patent removes the thin film electrode from the light transmission path by extracting it from between the PFA layer and color film layer. Instead, the DBS electrode setting is retained in its original position, eliminating the additional light interface that caused increased reflectivity while preserving the improved pixel opening rate achieved through the transparent conductive layer design.

The patent introduces the DBS electrode as an intermediary element positioned between the PFA layer and color film layer. This mediator structure serves dual functions: maintaining the electrical connection needed for pixel operation and reducing light reflection by providing a refractive index transition that minimizes optical impedance mismatch, thereby solving the reflectivity problem while preserving the high pixel opening rate.

The patent extracts the harmful light interface created by the thin film electrode from the optical path. By removing this additional interface that caused reflectivity and display degradation, the patent allows light to pass more directly through the pixel area, thereby maintaining the high pixel opening rate while significantly improving the display effect through reduced optical interference.

The patent converts the potential harm of having multiple light interfaces into a benefit by strategically positioning the DBS electrode setting. The electrode structure is designed to create controlled refractive index transitions that, rather than increasing reflectivity, actually reduce it by providing gradual optical impedance matching, thus turning what could be a harmful multi-interface structure into a beneficial anti-reflection mechanism that improves display effect.
