摘要
The present invention relates to a method for compensating voltage drop of a display device, a system for voltage drop compensation, and a display device including the same. A method for compensating a voltage drop of a display device including a display panel, a maximum compensation voltage table MLEC LUT for voltage compensation when a voltage drop is a maximum in the display panel, and a voltage drop coefficient table LEC LUT representing voltage drop coefficients with respect to total output currents during one frame according to an embodiment of the present invention comprises: receiving an input image signal; gamma-converting the input image signal to obtain a pre-compensation data voltage; obtaining a first total output current flowing in all pixels PX of the display panel during one frame based on the input image signal; obtaining a first voltage drop compensation voltage V_LEC based on the voltage drop coefficient table LEC LUT and the maximum compensation voltage table MLEC LUT; and adding the first voltage drop compensation voltage V_LEC to the pre-compensation data voltage to obtain the post-compensation data voltage.
