Abstract: A display device includes a controller that generates first and second sub-frame image signals based on a frame image signal. The first and second sub-frame image signals respectively correspond to sub-frames. The controller includes a filter, a signal generator, and a signal output. The filter outputs a high frequency image signal, obtained by increasing a high frequency component in the frame image signal, and a low frequency image signal obtained by decreasing the high frequency component in the frame image signal. The signal generator generates an excess signal from a portion of the high frequency image signal having a grayscale value equal to or greater than a maximum allowable grayscale value. The signal output selectively outputs the first sub-frame image signal based on the excess signal and the high frequency image signal and the second sub-frame image signal based on the excess signal and the low frequency image signal.

Abstract: A sensor controller includes a neural network processing unit to receive a sensing signal from an input sensor and to output one of a first sensing result and a second sensing result using a prediction model. The sensor controller further includes a first input processing unit and a second input processing unit. The first input processing unit is to receive the first sensing result and to determine whether a first input is present based on the first sensing result. The second input processing unit is to receive the second sensing result and to calculate a coordinate signal for a second input based on the second sensing result.

Abstract: A display device includes a display panel, an input sensing layer disposed on the display panel and which outputs a sensing signal in response to an external input and an approach of an object, and a sensing controller which controls a drive of the input sensing layer and receives the sensing signal from the input sensing layer. The sensing controller includes a location sensing block which generates a location information signal including location information of the external input in response to the sensing signal, and an approach sensing block which determines whether the object approaches in response to the sensing signal and generates an approach information signal.

Abstract: An image processor of a display device includes: an image sticking object detector which classifies a class of an input image data and outputs inference data including image sticking object information based on the classified class; a memory which stores previous inference data; a post-processor which calculates accumulative inference data, based on the inference data and the previous inference data received from the memory and generates corrected inference data, based on the accumulative inference data; and an image sticking prevention part which outputs an image data subjected to an image sticking prevention process, based on the corrected inference data.
