The present invention relates to technology which can provide a pixel compensation function, and compensate for data based on previous sensing data when pixel compensation fails. The present invention provides a display device comprising: a display panel in which data lines and gate lines are formed, sub-pixels are formed at respective points at which the data lines and the gate lines intersect each other, and sensing lines which are connected to circuits in rows of the sub-pixels every one or more rows of the sub-pixels; a data drive unit which provides data voltages to the data lines; an analog digital converter (ADC) which converts sensing voltages measured via sensing channels corresponding to each of the sensing lines into sensing data in a digital form; and a timing controller which controls the data drive unit, and performs pixel compensation which changes data to be provided to a corresponding sub-pixel based on the sensing data, and changes the data to be provided to a corresponding sub-pixel based on previous sensing data when the sensing data is abnormal. |
