A display panel driving apparatus includes an interface, a timing controller, a gate driver, and data driver. The interface includes a data determiner to determine whether or not input image data has a communication error and to process a packet of a data stream of the input image data, even though the input image data has the communication error. The timing controller receives the processed input image data from the interface and generates a data signal, a gate control signal, and a data control signal. The gate driver generates a gate signal based on the gate control signal. The data driver generates a data voltage based on the data control signal and the data signal.
