Display device and electronic equipment

摘要

A display device is disclosed. The display device includes: a pixel array unit and a driving unit which drives the pixel array unit. The pixel array unit includes rows of first scanning lines and second scanning lines, columns of signals, pixels in a matrix state arranged at portions where the scanning lines and the signal lines cross each other and power supply lines and ground lines supplying power to respective pixels. The driving unit includes a first scanner performing line-sequential scanning to pixels by each row by supplying a first control signal to each first scanning line sequentially, a second scanner supplying a second control signal to each second scanning line sequentially so as to correspond to the line-sequential scanning and a signal selector supplying a video signal to rows of signal lines so as to correspond to the line-sequential scanning.

主权项

1. A display device, comprising:
a first voltage line, a second voltage line, a third voltage line, and a plurality of pixels, at least one of the plurality of pixels comprising:
a light emitting element;a sampling circuit;a first switching circuit connected between the third voltage line and the light emitting element;a pixel capacitor; anda control circuit connected to the light emitting element between the first voltage line and the second voltage line, wherein a compensation current is configured to flow to the pixel capacitor via the control circuit to subtract from a potential stored in the pixel capacitor while an image signal is applied to the at least one of the plurality of pixels, wherein the control circuit is configured to supply a drive current to the light emitting element according to the subtracted potential in the pixel capacitor, and wherein the control circuit includes a first transistor whose size ratio W/L is at least 0.5, where W is a channel width and L is a channel length.
