In this work, the intrinsic polaron dynamics in the device are comprehensively investigated in terms of the polaron and exciton behaviors through the numerical simulation with transient electroluminescence (EL). Furthermore, the degradation mechanism generated by bimolecular interaction is investigated by considering the reduction of the luminance and voltage rising. As a result, the polaron, exciton, and recombination coefficient could be quantified via numerical simulation. Based on this, it is revealed that suppressing the exciton‐polaron interaction is crucial to improving the long operational lifetime in exciplex‐forming cohost based PHOLEDs.","PeriodicalId":91069,"journal":{"name":"Digest of technical papers.

According to the application concept of product, the 360 degree hinge and flexible screen have been developed with U‐shaped out‐fold and water‐drop shaped in‐fold. Based on the finite element method, the mechanical simulation model of flexible screen is established, and the modeling method is programmed which is applied to practical engineering test. Based on Lagrange equation and multi‐body system dynamics theory, a system‐level simulation model of rigid‐flexible coupling of 360‐degree folding terminal is established to solve the complex kinematics and dynamic problems, and to achieve the optimal design of each functional module in the mechanism. Combined with the monomer bending test of the flexible screen, the simulation and test results show good consistency.
