Which risk increases when polymers in flexible OLED screens degrade?

A)Increased singlet oxygen formation
B)Reduced excitonic energy transfer
C)Decreased electrode work function
D)Elevated quantum dot aggregation

💡 Explanation

The risk of decreased excitonic energy transfer increases with polymer degradation because chain scission weakens Covalent bonds reducing energy transfer efficiency; therefore excitons can't readily move to the emissive layer; rather than creating light, energy dissipates more through destructive thermal pathways.
