Abstract:
1. A method of driving an active matrix electroluminescent display device comprising a pixel provided with a switching thin film transistor formed over a glass substrate and a light emitting element, comprising: inputting a selecting signal to the switching thin film transistor; inputting a digital video signal to the pixel; controlling light emission or non-light emission of the light emitting element based on the digital video signal; and dividing frame periods into two or more subframe periods, wherein an order of appearance of the subframe periods of pixels arranged in a number K-th line (where K is a natural number) differs from an order of appearance of the subframe periods of pixels arranged in a number L-th line (where L is a natural number; L≧K), wherein the order of appearance of the subframe periods of the pixels arranged in the number K-th line is the same as an order of appearance of the subframe periods of pixels arranged in a number M-th line (where M is a natural number, M>L, and wherein, in each of the frame periods, the pixels arranged in the number L-th line are selected for the first time after the pixels arranged in the number K-th line are selected for the first time, and the pixels arranged in the number M-th line are selected for the first time after the pixels arranged in the number L-th line are selected for the first time.
