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 processor 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.
