Abstract
The present invention provides a display device comprising: a display panel including data lines, gate lines, a sub-pixel formed in every point where the gate lines and the data lines cross, and a sensing line formed in every sub-pixel row or every two or more sub-pixel rows, the sensing line being connected to a circuit in the sub-pixel row; a data driving unit that provides a data voltage to the data lines; an Analog Digital Converter (ADC) that converts a sensing voltage measured through a sensing channel corresponding to each sensing line into sensing data of a digital type; and a timing controller that controls the data driving unit, and performs a pixel compensation which changes data provided to a corresponding sub-pixel based on the sensing data, and when the sensing data is abnormal, changes the data provided to the corresponding sub-pixel based on previous sensing data.
