Method for generating control signal, control-signal generation circuit, data-line driving circuit, element substrate, optoelectronic device, and electronic apparatus

A data-line driving circuit to supply an image signal to a pixel circuit provided at a position corresponding to an intersection of a data line and a scan line via the data line, the data-line driving circuit comprising:

• a shift register to control outputting of a sampling signal supplied via a sampling-signal line;
• a capacitive element having a first terminal connected to the sampling-signal line, a second terminal, and a capacitance provided therebetween;
• an image-signal line to transmit an image signal;
• and
• a switching element controlled by a control signal output from an output unit connected to the second terminal in response to the sampling signal supplied to the first terminal via the sampling-signal line, the switching element being turned on when the control signal is supplied, whereby the image signal transmitted through the image-signal line is transmitted to the data line via the switching element.

A control signal generation circuit to output a control signal to control transmission of a scan signal supplied to a pixel via a scan line or a data signal supplied to the pixel via a data line, the control signal generation circuit comprising:

• a signal conversion unit having a first terminal and a second terminal;
• a first sampling signal line connected to the first terminal, which supplies a first sampling signal;
• and
• a second sampling signal line connected to the second terminal, which supplies a second sampling signal;
• the control signal being generated based on a first potential at the first terminal and a second potential at the second terminal,
• the first potential at the first terminal being controlled by the first sampling signal;
• and
• the second potential at the second terminal being controlled by the second sampling signal.
