Display device, image signal correction system, and image signal correction method

An image signal correction system, comprising:

• a luminance and color measurer that measures luminance and color of a display unit having a plurality of pixels that emit light according to a test image data signal transmitted to the display unit;
• a sample acquisition unit that acquires at least one luminance measured value and color measured value among luminances and colors of the display unit;
• a correction operator comparing the acquired luminance measured value and color measured value with a luminance target value and a color target value corresponding to the predetermined test image data signal, and generating a look-up table that represents a correction amount of the test image data according to the comparison result;
• and
• a memory unit storing the look-up table.

An image signal correction method, comprising:

• transmitting a test image data signal to a display unit;
• measuring luminances and colors of the display unit emitting light according to the test image data signal;
• acquiring at least one luminance measured value and color measured value among the luminances and colors;
• comparing the acquired luminance measured value and color measured value with a luminance target value and a color target value corresponding to the test image data signal;
• generating a look-up table that represents a basic correction amount of the test image data according to the comparison result;
• and
• controlling an image data signal supplied to the display unit according to the look-up table.
