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.

Abstract: A display device and a driving method thereof are proposed, the display device including an image conversion apparatus receiving a first image signal from the outside and outputting a second image signal by converting a luminance of the received first image signal; a controller generating image data based on the second image signal; a source driver outputting data signals based on the image data; a display panel including a plurality of sub-pixels that emit light based on the data signals; and a memory, wherein the image conversion apparatus generates the second image signal by converting the luminance of the first image signal in such a manner a to satisfy a reference maximum luminance value stored in the memory.
