Abstract: A display apparatus includes a controller which generates control signals and outputs image data, a compensating circuit which receives a portion of the control signals from the controller and generates a compensation signal, a voltage generating circuit which converts an input voltage to a driving voltage and increases or decreases a voltage level of the driving voltage in a frame period in response to the compensation signal, a driving part which receives the control signals and the image data from the controller and receives the driving voltage from the voltage generating circuit to generate a panel driving signal, and a display panel which receives the panel driving signal from the driving part to display an image.
