The invention discloses a display panel correction method and correction module for applying the aforementioned display panel correction method to a display panel which has a plurality of pixels so as to correct output values of the output pixels. The display panel correction method includes the following steps: a step of dividing in which the pixels of the display panel are divided according to a set unit in order to set a plurality of unit blocks; a step of setting in which a plurality of detail regions which are configured in an identifical form corresponding to the configurations of the pixels which are contained in the unit blocks in order to separately set a correction display checkup table having correction values for each detail region; and a step of generation in which values of decimal parts of the parts in exception of integer part are derived from an average output value of the pixels that are output from each of the unit block in order to generate a representative value from the interger part, and the correction display checkup table corresponding to the values of decimal parts is applied to the pixels with each unit block so as to generate a correction output value for performing correction and carry out correction.
