Abstract:
Disclosed are an organic light emitting diode (OLED) display device and a method for driving the same, which are capable of simplifying the configuration of an overcurrent prevention circuit while preventing overcurrent generation at an image display panel, and achieving a reduction in production costs. The OLED display device includes an image data converter for analyzing input image data, to reduce the possibility of overcurrent generation and to prevent overcurrent generation, modulating image data and a grayscale voltage level (or a gamma voltage level) of a next frame when overcurrent is generated, and outputting the modulated image data and the modulated grayscale voltage (or the modulated gamma voltage), and a timing controller for arranging the image data from the image data converter to match a size of an image display panel, supplying the arranged image data to a data driver, and generating a data control signal to control the data driver.
