Display apparatus and driving method therefor, and electronic device

A drive method for a display apparatus which includes a pixel array section and a drive section for driving the pixel array section,

• the pixel array section including scanning lines arranged in rows, signal lines arranged in columns, pixels arranged in a matrix, and predetermined power feed lines,
• the drive section including a control scanner adapted to sequentially output control signals to the respective scanning line and carrying out line progressive scanning on the pixels in units of a row, and
• a signal driver adapted to supply the signal lines arranged in columns with a signal potential which is a video signal and a reference potential in accordance with the line progressive scanning,
• the pixel including a light emitting element, a sampling transistor, a drive transistor, and a holding capacitance,
• the sampling transistor having a gate connected to the scanning line, one of a source and a drain connected to the signal line, and the other of the source and the drain connected to the drive transistor,
• the drive transistor having one of a source and a drain connected to the light emitting element and the other of the source and the drain connected to the power feed line,
• the holding capacitance being composed of a display apparatus connected between the source and the gate of the drive transistor, the method comprising the steps of:
• allowing, after the sampling transistor is turned ON at a first timing when the control signal has risen, during a sampling period from a second timing when the video signal has risen from a reference potential to a signal potential to a third timing when the control signal has fallen and is turned OFF, the sampling transistor to sample the signal potential and write the signal potential in the holding capacitance,
• allowing the sampling transistor to also carry out negative feedback on a current flowing into the drive transistor during the sampling period to the holding capacitance and apply a correction with respect to a mobility of the drive transistor on the signal potential written in the holding capacitance,
• allowing the drive transistor to supply a drive current to the light emitting element in accordance with the corrected signal potential to emit light, and
• allowing the signal driver to adjust the second timing for the video signal supplied to the respective signal lines to correct a backward shift of the third timing due to a transmission delay along the scanning line of the control signal output from the control scanner.
