Display burn-in prevention device and method with motion analysis

摘要

Provided is a display device including a video signal analysis block (110) for analyzing a video signal and determining a type of video from an analysis result, a function control block (120) for controlling a gain value of the video signal according to the type of video, a video signal control section (122) for adjusting the video signal on the basis of the gain controlled by the function control block, and a display panel (300), having a plurality of pixels arranged to self-emit light according to the video signal, for displaying a video on the basis of the video signal adjusted by the video signal control section (122).

主权项

1. A display device comprising:
circuitry configured to
determine a type of video data of a video signal as corresponding to a still image, a partial moving image or a moving image based on a generated a motion vector of a feature point between a plurality of frames of the video signal and histograms of each of the plurality of frames of the video signal;record a duration of a still image if it is identified that the video signal corresponds to a still image;control a gain value of the video signal according to the type of video data;adjust the video signal based on the gain value; andcontrol a display panel to display a video image based on the adjusted video signal.
