Image display device having functions for protecting an address driver

Abstract

Disclosed is an image display device having functions for protecting an address driver. The image display device includes a panel provided with address electrodes and data electrodes, a scaler for converting an input image signal to fit into a resolution of the panel, an address driver and a data driver for driving the address electrodes and the data electrodes, respectively, in response to an image signal from the scaler, and a luminance control unit for comparing line by line changes of the image signal outputted from the scaler, changing luminance of the image signal outputted from the scaler, and changing the number of operations of the address driver. Such an image display device decreases a parasitic capacitance in an address driver for driving a PDP, to thereby prevent the address driver from being overloaded.

Dependencies are inferred from the claim text.
