Display device and checking system including the same

A checking system comprising:

• a display device configured to display a stereoscopic image through a display panel to which an optical member is attached;
• and
• a checking device configured to detect optical characteristics of a display image for each viewing viewpoint of the display panel and configured to generate and output a correction coefficient for each viewing viewpoint according to the optical characteristics for each viewing viewpoint,
• wherein the checking device is configured to:
• modulate an optical path of the display image for each viewing viewpoint by reflecting and refracting the display image that is displayed on the display panel for each viewing viewpoint,
• generate optical characteristic detection signals by detecting the optical characteristics of the display image for each viewing viewpoint in which the optical path is modulated, and
• extract a correction coefficient for each viewing viewpoint according to an analysis result of the optical characteristic detection signals for each viewing viewpoint and supply the extracted correction coefficient to the display device.

An electronic device including a display device,

• wherein the display device comprising:
• a display panel including a display area and a plurality of sub-pixels disposed in the display area;
• an optical member bonded onto the display panel;
• and
• a display driving unit configured to receive a correction coefficient for each viewing viewpoint of the display panel from a checking device of the display panel, to which the optical member is bonded, configured to correct image data for each viewing viewpoint using the correction coefficient for each viewing viewpoint, and configured to drive the display panel so that an image according to the corrected image data is displayed in the display area, wherein the correction coefficient is obtained by comparing an optical characteristic of a display image for one viewing viewpoint with an average optical characteristic value of remaining viewing viewpoints for the display image.
