“…In 2018, Weiwei Deng et al reported an OLED with solution-processed WO 3 -P 2 O 5 , which showed a lower driving voltage for 2.6 V and maximum brightness for 13,553 cd m −2 , respectively [ 62 ]. In 2019, Mangey Ram Nagar et al reported that a solution-processed OLED with MoO 3 :WO 3 showed a PE of 22.9 lm W −1 at 1000 cd m −2 , which was ascribed to the robust hole transporting ability, balanced charge carrier, and non-acidic nature of transition metal oxide HILs [ 69 ].…”

Organic light-emitting diodes (OLEDs) are widely recognized as the forefront technology for displays and lighting technology. Now, the global OLED market is nearly mature, driven by the rising demand for superior displays in smartphones. In recent years, numerous strategies have been introduced and demonstrated to optimize the hole injection layer to further enhance the efficiency of OLEDs. In this paper, different methods of optimizing the hole injection layer were elucidated, including using a suitable hole injection material to minimize the hole injection barrier and match the energy level with the emission layer, exploring new preparation methods to optimize the structure of hole injection layer, and so on. Meanwhile, this article can help people to understand the current research progress and the challenges still faced in relation to the hole injection layer in OLEDs, providing future research directions to enhance the properties of OLEDs.
