Display device and image display device including same

An image display apparatus comprising:

• a display device;
• and
• a signal processing device configured to output an image signal to the display device,
• wherein the display device comprises:
• a plurality of light emitting diodes arranged in a matrix form;
• a plurality of first switching drivers configured to supply a scan signal or a voltage of a first level to anodes of the plurality of light emitting diodes for each first line based on a switching operation during a display mode period;
• a plurality of second switching drivers configured to supply a voltage of a second level less than the first level to cathodes of the plurality of light emitting diodes for each second line based on the switching operation during the display mode period;
• a first switch configured to output the scan signal or the voltage of the first level during the display mode period and not output the scan signal or the voltage of the first level during a sensing mode period separate from the display mode period;
• a second switch configured to output the voltage of the second level during the display mode period and output a current flowing in at least one of the plurality of light emitting diodes based on a pointer light during the sensing mode period;
• and
• an amplifier configured to amplify a difference between a first line voltage and a second line voltage based on the current flowing in the light emitting diode during the sensing mode period.
