Abstract: A liquid crystal display device includes a plurality of pixels arranged substantially in a matrix form, where a part of the plurality of pixels defines a pixel column block, a first scan signal is simultaneously applied to an n-th row pixel and an (n+2)-th row pixel of the pixel column block, a second scan signal, which is applied prior to the first scan signal, is simultaneously applied to an (n+1)-th row pixel and an (n+3)-th row pixel of the pixel column block, a first data voltage is applied to the n-th row pixel and the (n+1)-th row pixel, a second data voltage having a polarity different from a polarity of the first data voltage is applied to the (n+2)-th row pixel and the (n+3)-th row pixel, and the polarities of the first data voltage and the second data voltage are inverted on a frame-by-frame basis.

Abstract: A display device including pixels connected to a data line and a sensing line; a data driver supplying one of an image data signal and a sensing data signal to the data line; a sensing unit supplying an initialization voltage to at least one of the pixels through the sensing line and obtaining a sensing current value from at least one of the pixels through the sensing line; and a compensator generating compensation image data according to a sensing pixel current value among the sensing current value using an artificial neural network model learned to output reference image data corresponding to at least one reference sensing current value among the sensing current value.
