Abstract: The present application discloses a display device. The display device includes a display panel and a driving module. Each grayscale includes a positive polarity voltage and a negative polarity voltage symmetrical with respect to a common voltage. A data line is configured to output corresponding data voltages to each sub-pixel respectively. The driving module includes an adjustment unit. The adjustment unit is configured to increase the voltage values of the positive polarity voltages to obtain the compensated positive polarity voltages. The data voltages are the negative polarity voltages or the compensated positive polarity voltages.
