Abstract:
A semiconductor integrated circuit and corresponding display panel and electronic apparatus. A pixel element includes a self-luminous element and a drive transistor connected to a power supply line. In an emission period of the self-luminous element, an active voltage and an intermediate voltage are sequentially applied between the power supply line and a potential line with a pulse-shaped waveform such that a predetermined luminance duration is obtained in the emission period. In a non-emission period of the self-luminous element, an off-state voltage is applied between the power supply line and the potential line so as to maintain the self-luminous element in a non-emission state.
