Display device and electronic device using the same

A display device comprising:

• display pixels in a display area of a display panel;
• infrared (IR) light-emitting pixels in the display area;
• light-sensing pixels in the display area;
• a display scan driver configured to drive the display pixels to emit light;
• a light-sensing scan driver configured to drive the light-sensing pixels to sense light;
• and
• a main driver circuit configured to receive first and second light-sensing signals through first and second light sensing lines connected to the light-sensing pixels,
• wherein each of the light-sensing pixels comprises at least two photo-detecting elements spaced from each other, and
• wherein the first and second light-sensing lines are configured to transmit the first and second light-sensing signals generated from the at least two photo-detecting elements.

An electronic device including a display device, the display device comprising:

• a display panel having an image display area comprising image display pixels, infrared (IR) light-emitting pixels, and light-sensing pixels;
• a display scan driver configured to drive the image display pixels and the IR light-emitting pixels to emit light;
• a light-sensing scan driver configured to drive the light-sensing pixels to sense light;
• and
• a main driver circuit configured to receive first and second light-sensing signals through first and second light-sensing lines connected to the light-sensing pixels,
• wherein each of the light-sensing pixels comprises at least two photo-detecting elements spaced from each other, and
• wherein the first and second light-sensing lines are configured to transmit the first and second light-sensing signals generated from the at least two photo-detecting elements.
