Abstract
A display device including: a sensor part including sensors; a sensor driver that transmits a sensing signal to p sensors of a first area of the sensor part in a first mode and a sensing signal to q sensors in the first area in a second mode; and a display driver that transmits a light emitting signal to pixels for the pixels to have s non-light emitting periods during one frame period in the first mode, and the light emitting signal to the pixels for the pixels have t non-light emitting periods during the one frame period in the second mode, wherein p is an integer larger than 0, q is an integer larger than p, s and t are integers larger than 1, and a sum of lengths of the t non-light emitting periods is larger than a sum of lengths of the s non-light emitting periods.
Claims20
A display device, comprising:
- a sensor part including sensors;
- a sensor driver that transmits a sensing signal to a first area of the sensor part in units of p sensors in a first mode, and transmits a sensing signal to the first area in units of q sensors in a second mode;
- a display part overlapping the sensor part and including pixels;
- and
- a display driver that transmits a light emitting signal to the pixels so that the pixels have s non-light emitting periods during one frame period in the first mode, and transmits the light emitting signal to the pixels so that the pixels have t non-light emitting periods during the one frame period in the second mode,
- wherein p is an integer larger than 0,
- q is an integer larger than p,
- s and t are integers larger than 1, and
- a sum of lengths of the t non-light emitting periods is larger than a sum of lengths of the s non-light emitting periods.
A driving method of a display device, comprising:
