Abstract
A display apparatus comprises a display panel including a plurality of data lines and a plurality of gate lines, a data driver circuit configured to convert image data to a grayscale voltage and to output the grayscale voltage to a data line, a voltage generator configured to provide the data driver circuit to a driving voltage, and a heat blocking circuit configured to compare a load current voltage with a reference voltage and to output a control signal for controlling the data driver circuit, the load current voltage being proportionate to a load current flowing toward the data driver circuit.
