Abstract
A display apparatus includes an image analyzer that analyzes image data and outputs an interrupt signal at a period during which the image data of a low frequency change to the image data of a high frequency, a frequency detector that detects the high frequency, a frame rate controller that outputs a vertical synch signal of the high frequency in response to the interrupt signal, a polarity compensation controller that determines a last frame of the low frequency based on an interrupt period at which the interrupt signal is generated, generates a reversed polarity signal with respect to a polarity signal of the last frame and outputs the reversed polarity signal during a polarity compensation period close to the interrupt period, and a data driver circuit that outputs a data signal based on the reversed polarity signal to a data line during the polarity compensation period.
