Abstract
A correction device for correcting luminance of a display image based on background illuminance and transmittance of a transparent display panel, a transparent display device using the same, and a method for driving the display device are discussed. The correction device can correct luminance of a display image in real time based on a background-affected illuminance of a transparent display panel. Further, an optimal peak luminance of the display image is adjusted based on the background-affected illuminance of the transparent display panel, while adding a weight to a dark environment such that the peak luminance is further lowered, thereby reducing an amount of power consumption while maintaining display quality of the transparent display image.
