Abstract
According to one embodiment, a display apparatus includes a plurality of pixels and a plurality of control lines. A pixel circuit of each of the pixels includes a driving transistor, an output switch, a pixel switch and a storage capacitance. A number of pixels PX of the plurality of pixels which are adjacent to one another in a column direction share the output switch.
Claims19
A display apparatus comprising:
- a plurality of pixels each comprising a display element connected between a high-potential power supply and a low-potential power supply and a pixel circuit controlling driving of the display element, the pixels being provided in a matrix along a row direction and a column direction;
- and
- a plurality of control lines comprising a plurality of reset lines and extending in the row direction to connect to the pixel circuits of the plurality of pixels,
- the pixel circuit comprising:
- a driving transistor comprising a source electrode connected to the display element, a drain electrode connected to the reset line, and a gate electrode;
- an output switch connected between the high-potential power supply and the drain electrode of the driving transistor and configured to switch a state between the high-potential power supply and the drain electrode of the driving transistor to an electrically continuous state or an electrically discontinuous state;
- a pixel switch connected between a video signal line and the gate electrode of the driving transistor and configured to determine, in a switchable manner, whether to load a signal provided through the video signal line onto the gate electrode side of the transistor;
- and
- a storage capacitance connected between the source electrode and the gate electrode of the driving transistor,
- wherein a number of pixels PX of the plurality of pixels which are adjacent to one another in the column direction share the output switch.
