a The structure of large-area WLED, where heterophase γ/δ-CsPb(I/Cl)3 film acts as an emitting layer. b A structure diagram of large-area WLED with the overlapped 1 cm × 1 cm emitting area of patterned ITO and Al electrode. EL performance of large-area WLED. J–V–L (c), EQE (d), and CE curves (e) of the control and champion devices. EL quality of large-area WLED. CIE coordinates (f), CRI (g), CCT (h), and Duv (i) of a typical device driven by different applied voltages.
