The present invention relates to a technology for enabling a driving chip provided at an outer portion of an OLED panel to calculate and to compensate for the luminance deviations of pixel elements arranged in a display area through the use of a reference pixel provided at an adjacent location. The present invention comprises: a reference pixel element unit which is provided at an outer portion of a display area on an organic light emitting diode panel and operates corresponding to the pixel elements arranged in the display area; and a driving chip which is equipped in an area, in which the reference pixel element unit is included, of the outer portion of the display area, compares the luminance value of light incident from the reference pixel element unit with a reference luminance value, calculates a luminance deviation value according thereto, and controls the driving of the pixel elements arranged in the display area according to the luminance deviation value so that light, the luminance deviation of which has been compensated for, is irradiated. |
