Abstract:
1. An active matrix display device comprising: a plurality of pixel units arranged in a matrix on a substrate, each of the pixel units including a display element and a pixel circuit which supplies a driving current to the display element; a plurality of video signal lines connected to columns of the pixel units, respectively; and a signal line driving circuit which supplies a first signal current to the pixel circuit via the video signal line and then supplies a second signal current to the pixel circuit via the video signal line, each of the pixel circuits including a first memory section which stores, in a write period of the pixel unit, a first driving current corresponding to the first signal current and then outputs the stored first driving current, and further stores a second driving current corresponding to the second signal current, and a second memory section which stores the first driving current which is output from the first memory section in the write period of the pixel unit, and each of the pixel circuits being configured to output, in a light emission period of the pixel unit, a difference current between the second driving current stored in the first memory section and the first driving current stored in the second memory section to the display element as the driving current.
