Active matrix display apparatus having a change in lighting power source before the end of a writing period and driving method thereof

摘要

An active matrix display apparatus includes two-dimensionally arranged pixel circuits, each of which includes a display element, and a plurality of signal lines and scanning lines connected to the pixel circuits. Each of the pixel circuits include a drive transistor and a capacitor, with one terminal of the capacitor being connected to a control terminal of the drive transistor and a second terminal of the capacitor being connected to a first main conductive terminal of the drive transistor and a lighting power source. In a writing operation period, a current flowing to the signal line is conducted into the drive transistor, and in a lighting operation period, a current conducting in the drive transistor is injected into the display element. At a time during the writing operation period, a potential of the lighting power source is changed toward a potential of the signal line to depress the current conducting in the drive transistor and is kept for a period, during which the current conducting in the drive transistor partially recovers from the depression. After the writing operation period, the potential of the lighting power source is restored.
