Simple model for the hysteretic behavior of thin-film electroluminescent devices

The hysteretic behaviour of TFEL (thin-film electroluminescent) devices can be simulated relatively well with the numerical model introduced by W.E. Howard et al. (1982). An approximate model is developed by introducing a time-independent space-charge distribution. With this method, steady-state solutions can be calculated very efficiently. Hysteretic curves obtained with this method are given for different frequencies, and the results are discussed.<
