Abstract: An object of the present disclosure is to prevent burn-in of a display panel by using a combination of RGBW data maintaining the same color and brightness as an original image.

Abstract: Disclosed are a display device and an operating method therefor. According to an aspect of the present disclosure, a display device comprises a video decoder; a display configured to output videos; and a processor configured to control the video decoder, wherein, when a first video frame to be output through the display having a resolution different from that of the previous frame is detected among the video frames decoded by the video decoder, the processor is configured to control a resolution of the first video frame and at least one second video frame which is adjacent to the first video frame to be changed.

Abstract: A method for displaying a three-dimensional (3D) image includes: alternately displaying a left eye image and a right eye image; calculating a luminance value of a displayed image to detect a peak value of a luminance value; comparing the detected peak value and a stored peak value, and when the detected peak value corresponds to a right eye peak value, determining that a current image is a right eye image, and when the detected peak value corresponds to a left eye peak value, determining that the current image is a left eye image; outputting a synchronization signal according to the determination result; and making the left eye image and the right eye image reach a user's left eye or right eye according to the synchronization signal.
