Abstract
A display device includes sub-pixels connected to scan lines and data lines, light-sensing pixels connected to sensing scan lines, readout lines, and a reset control line, a scan driver supplying a scan signal to the scan lines, and a controller supplying a start signal to the scan driver. The controller may supply the start signal at a first time point after a start of a frame during some frame periods among a plurality of frame periods in which a sensing signal is detected from the light-sensing pixels, and supply the start signal at a second time point different from the first time point after the start of the frame during remaining frame periods.
Claims20
A display device comprising:
- sub-pixels connected to scan lines and data lines;
- light-sensing pixels connected to sensing scan lines, readout lines, and a reset control line;
- a scan driver supplying a scan signal to the scan lines;
- and
- a controller supplying a start signal to the scan driver,
- wherein the controller supplies the start signal at a first time point after a start of a frame during some frame periods among a plurality of frame periods in which a sensing signal is detected from the light-sensing pixels, and supplies the start signal at a second time point different from the first time point after the start of the frame during remaining frame periods.
A display device comprising:
- sub-pixels, each of the sub-pixels including a light emitting element, receiving a data signal from a data line when a first scan signal is supplied to a first scan line, and initializing a gate electrode of a driving transistor when a second scan signal is supplied to a second scan line;
- light-sensing pixels, each of the light-sensing pixels including a light receiving element and detecting an external input;
- a write driver supplying the first scan signal to the first scan line in response to a write start signal;
- an initialization driver supplying the second scan signal to the second scan line in response to an initialization start signal;
- and
- a controller supplying the write start signal and the initialization start signal to the write driver and the initialization driver,
- wherein the controller does not supply the initialization start signal to the initialization driver during a plurality of frame periods in which a sensing signal is detected from the light-sensing pixels.
An electronic device, comprising:
- a processor to provide input image data;
- and
- a display device to display an image based on the input image data,
- wherein the display device comprises:
- sub-pixels connected to scan lines and data lines;
- light-sensing pixels connected to sensing scan lines, readout lines, and a reset control line;
- a scan driver supplying a scan signal to the scan lines;
- and
- a controller supplying a start signal to the scan driver,
- wherein the controller supplies the start signal at a first time point after a start of a frame during some frame periods among a plurality of frame periods in which a sensing signal is detected from the light-sensing pixels, and supplies the start signal at a second time point different from the first time point after the start of the frame during remaining frame periods.
