Which outcome results to an organic LED when bias weakens?

💡 Explanation

Exciton formation diminishes greatly because reduced bias provides less energy; therefore the weaker external electric field will inhibit electron–hole attraction and formation, rather than assisting charge carrier mobility or pushing radiative recomination by a different source.
