P‐202: Research on the Effect of Anisotropic Module Layers on the White‐Angle Difference of OLEDs

This study focuses on the module layer in OLED products, which is a uniaxial anisotropic material that causes birefringence of the emitted light through the layer. After simulation and experimental investigation, it is found that this anisotropic module layer will play a role in the white angle difference (WAD) of the product. Theoretically analyzing the principle, and through systematic testing, it is determined that the effect of the module layer on the WAD of the product can be minimized under a specific optical axis angle.
