  2. After introducing the background and the trend of research on ppv thin film light - emitting diodes ( leds ) and the structure of ppv device and its characterizes, the theoretical model of the leds * light - emitting efficiency was presented. based on this model, the formula of light - emitting efficiency was deduced to be : the injecting - currents and the recombining - efficiencies were calculated nwnerically, we found the calculated results agreed very well with the experimental results under the electric field from 0. 5 x 106 to 1. 5 x 106v / cm, the numeral calculations and theoretical analyzes of the light - emitting efficiency were done. the conclusions were as follows : ( 1 ) the basic mechanism of the injection transportation and recombination of the carriers which were presented in this paper were proved to be right ; ( 2 ) the electroluminescence in ppv thin film is the result of exciton recombination, the light - emitting efficiency was affected by many factors
