Method of driving a display panel, and display apparatus for performing the method
View Patent ↗Disclosed is a method of driving a display panel, which includes a plurality of data lines, a plurality of gate lines, a first pixel column electrically connected to an N-th gate line and a second pixel column electrically connected to an (N+1)-th gate line adjacent to the N-th gate line (wherein N is a natural number). In the method, compensation data of the first pixel for compensating for a kickback deviation between the first and second pixel columns is generated using first data and second data corresponding to the first and second pixel columns, respectively. The compensation data of the first pixel column and the second data of the second pixel column are converted to data voltages of an analog type to output the data voltages to the data lines.
