    Abstract: The present disclosure provides a display device. The display device includes a plurality of pixels, a data driver, and a timing controller. The plurality of pixels are connected to a plurality of scan lines and a plurality of data lines. The data driver supplies a data voltage to the plurality of data lines in a light-emitting mode and supplies a neural network input voltage to the plurality of data lines in an artificial neural network mode. The timing controller is in an artificial neural network mode, and supplies a weight value control signal for performing a deep learning operation by using at least one of the plurality of pixels to the data driver. The weight value control signal is generated based on a predetermined weight value.

    Abstract: A display device and a method of operation that can reduce memory utilization during a pixel shift operation. The device includes a display panel including a first pixel and a second pixel, a processor configured to generate a first image data corresponding to the first pixel, and a first timing control signal. An image corrector is configured to generate a second image data corresponding to the second pixel based on the first image data, and shift the first timing control signal by using a positional relationship between the first pixel and the second pixel to generate a second timing control signal. A data driver is configured to generate a data signal based on the second image data and the second timing control signal.

    Abstract: A display device includes pixels, an image converter generating second image data using first image data of an N-th frame and first image data of an (N+1)th frame; and a data driver supplying a data signal corresponding to the second image data to the pixels during an (N+1)th frame period. The image converter detects a logo and a logo area using the first image data, calculates a first representative value of data corresponding to a peripheral area of the logo area among the first image data of an N-th frame and a second representative value of data corresponding to a reference area among the first image data of the (N+1)th frame, and selectively converts data for the logo among the first image data of the (N+1)th frame according to the first representative value and the second representative value to generate the second image data of the (N+1)th frame.
