Abstract: A display device is capable of sensing a user's touching or inputting by a laser pointer on a display panel, by means of arranging a photo transistor in some pixels of the display panel to sense off-current of the photo transistor according to a change in the quantity of external light. In addition, a common electrode overlapping a data line is arranged separately from a common electrode overlapping a read-out line from which a sensing signal is detected, thereby improving the sensing performance carried out simultaneously with the display driving, owing to reduced influence of noise caused by the display driving to the sensing signal.

Abstract: A display device can include a display panel having an display area and a dummy area surrounding the display area, a plurality of sub-pixels disposed in the display area, a plurality of dummy sub-pixels disposed in the dummy area, a pixel circuit disposed in the plurality of sub-pixels, and at least a pair of low potential power supply lines disposed in each of the plurality of sub-pixels and the plurality of dummy sub-pixels. Therefore, it is possible to reduce or minimize transfer issues of light emitting elements in an outer portion of the display area by forming the low potential power supply lines for self-assembling the light emitting element in the dummy area.
