Figure 9. (A) The conventional OLED module structure (left) and pol-less OLED module structure (right). Excluding the polarizer necessitates the introduction of a black matrix on the color filter and a UV-blocking adhesive; (B) The UV-blocking adhesives were prepared via visible-light-driven polymerization. With UV-block adhesive, the luminescence and voltage change were negligible after UV exposure test^[27]. Reproduced with permission. Copyright © 2024 Springer Nature.
