1. A light emitting display apparatus comprising:
an analyzing circuit configured to analyze at least one of image change amount and current change amount by analyzing input image data, and to generate a driving frequency control signal according to analysis results;
a control signal generator circuit for generating driver control signals for changing a period of outputting data voltages according to the driving frequency control signal, transmitting a gate control signal of the driver control signals to a gate driver, and transmitting data control signals of the driver control signals to a data driver; and
a data aligning circuit for generating image data by rearranging the input image data transmitted from the analyzing circuit according to a structure of a light emitting display panel, and for outputting the image data to the data driver,
wherein the analyzing circuit comprises a scaler provided in a control driver together with the control signal generator and the data aligning circuit or configured to change image information received through a communication network into a signal recognizable by the control driver.
