Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 10:
11. A display device comprising:
a display panel including a plurality of pixels which are connected to a plurality of data lines and a plurality of scan lines;
a data driving circuit which drives the plurality of data lines;
a scan driving circuit which drives the plurality of scan lines; and
a driving controller which receives a control signal and an input image data of a current frame, controls the scan driving circuit such that an image is displayed on the display panel, and provides an image data to the data driving circuit,
wherein the driving controller includes:
an image sticking object detector which classifies a class of the input image data and outputs inference data including image sticking object information based on the classified class;
a memory which stores previous inference data accumulated up to a previous frame;
a post-processor which calculates final accumulative inference data based on the inference data of the current frame and the previous inference data accumulated up to the previous frame and received from the memory and generates corrected inference data based on the final accumulative inference data; and
an image sticking prevention part which outputs the image data subjected to an image sticking prevention process based on the corrected inference data,
wherein the memory stores the final accumulative inference data as the previous inference data for a next frame.
