Abstract:
1. An electroluminescent display panel having pixel circuits for an active matrix driving system, wherein at least one of the pixel circuits has a thin-film transistor in which a portion of a pattern of a metal wiring material above a channel layer of the thin-film transistor is positioned to shield a channel region of the thin-film transistor, the portion of the pattern of the metal wiring material being connected to receive a pulse signal through a variable source line that is electrically separate from a signal line and a gate of the thin-film transistor, the gate of the thin-film transistor being connected to a write control line configured for connection to a write control scanner, wherein a potential generated by the variable source line is set to change over time according to a variation of a threshold voltage of the thin-film transistor, and wherein the write control scanner is configured to adjust a duration of a transistor-characteristic correction of the pixel circuit according to a brightness level of the pixel circuit.
