The development of Organic Light Emitting Diode (OLED) devices has shown numerous advantages to date. To further develop and optimize OLED technology, modeling research has become crucial. However, existing OLED physical models are not conducive to industrial applications, and the accuracy of equivalent circuit models is insufficient. In this paper, a high‐precision segmented OLED device model is introduced, dividing the voltage into four regions for construction. This model can simulate and accurately predict the current‐voltage characteristics and capacitance‐voltage characteristics of OLED devices. Finally, the proposed model is imported into software for fitting, and simulation results show very small overall and partition errors, demonstrating good predictive performance in terms of voltage scalability.
