Abstract: A method of driving a display panel includes respectively outputting first to j-th, where j is a natural number, gate signals to first to j-th gate lines disposed on a first area of the display panel during a load period when an image is displayed on the display panel due to an output of a data signal to the display panel, adjusting a blank gate voltage during a blank period between load periods to generate an adjusted blank gate voltage, generating a blank gate signal based on the adjusted blank gate voltage, and outputting the blank gate signal. Thus, display quality of a display apparatus may be improved.
