Display apparatus and driving method therefor, and electronic device
View Patent ↗After a sampling transistor is turned ON at a first timing when a control signal has risen, during a sampling period from a second timing when a 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 samples and writes the signal potential in a holding capacitance, and negatively feeds back a current flowing into a drive transistor during the sampling period to the holding capacitance and applies mobility correction of the drive transistor on the written signal potential. A signal driver adjusts the second timing for the video signal supplied to respective signal lines to correct a backward shift of the third timing due to a transmission delay along a scanning line of the control signal output from the control scanner.
1. A display apparatus comprising:
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, and pixels arranged in a matrix, 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 with a video signal in accordance with the line progressive scanning, the signal driver adjusting a timing when the video signal has changed from a reference potential to a signal potential for the video signal supplied to the respective signal lines to correct a backward shift due to a transmission delay along the scanning line of a control signal output from the control scanner and to maintain a total period of a writing period and a mobility correction period constant.
