  • Patent number: 9759608
    Abstract: A color measuring device includes a color difference meter module. The color difference meter module includes: a main detecting unit having an optical detecting unit configured to receive light introduced from an incident lens to generate a first current depending on a color, a first measuring unit configured to measure the first current, a sub-detecting unit having a dark detecting unit disposed adjacent to the main detecting unit and blocking the light to generate a second current in a dark state, a second measuring unit configured to measure the second current, a leakage measuring unit including a charging unit provided in the second measuring unit and charged with a predetermined set current, and measures a third current leaking from the charging unit, and a control unit that corrects the first current by reflecting the second current and the third current.
