Abstract
A display includes a video signal line, a current source which outputs a video signal, a voltage source which outputs a reset signal, and pixels each of which includes a drive circuit and a display element. The display executes a reset operation during a blanking period. The reset operation includes connecting the voltage source to the video signal line to write the reset signal on the video signal line while disconnecting the current source from the video signal line.
Claims6
A display comprising:
- a video signal line;
- a current source which outputs a video signal;
- a voltage source which outputs a reset signal;
- and
- pixels which are arranged along the video signal line, each of the pixels including a drive circuit which outputs a drive current at a magnitude corresponding to a magnitude of a video signal, and a display element which changes its optical characteristics in accordance with a magnitude of a current flow through the display element,
- wherein the display is configured to alternately repeat an active scanning period and a blanking period, sequentially select the pixels during the active scanning period, execute a write operation on the selected pixel, execute a display operation on each of the non-selected pixels, and execute a reset operation during the blanking period,
- wherein the write operation includes connecting the drive circuit to the current source via the video signal line to write the video signal on the drive circuit while disconnecting the display element from the drive circuit,
- wherein the display operation includes connecting the drive circuit to the display element to make the drive current flow through the display element while disconnecting the drive circuit from the video signal line, and
- wherein the reset operation includes connecting the voltage source to the video signal line to write the reset signal on the video signal line while disconnecting the current source from the video signal line.
