Which risk increases when organic LED (OLED) materials exhibit poor orbital overlap?

💡 Explanation

When OLED materials have poor orbital overlap, exciton formation probability decreases due to less efficient charge carrier recombination via quantum mechanical tunneling because spatial separation reduces wave function interaction. This causes reduced light emission efficiency, rather than other issues which result from different failure mechanisms.
