摘要:
It is difficult to obtain a good image display by using an organic EL display panel. An EL display apparatus includes EL elements 15 and driving transistors 11a placed like a matrix, a voltage gradation circuit 1271 for generating a program voltage signal, a current gradation circuit 164 for generating a program current signal, and a drive circuit means of applying a signal to the driving transistors 11a, having switches 151a and 151b for switching between the program voltage signal and the program current signal.
