DISPLAY DEVICE AND DRIVING METHOD THEREOF

The present disclosure relates to a display device and a driving method thereof. The display device includes a display panel including a plurality of data lines, a plurality of gate lines, and a plurality of pixel lines connected to the data lines and the gate lines and having pixels arranged therein; a sensing unit configured to sense electrical properties of each of the pixels; a timing controller including a compensation unit configured to modulate pixel data to be written to the pixels based on sensed data from the sensing unit, a sensing error processing unit configured to analyze the sensed data to detect a sensing error, and a gate control unit configured to output a gate timing control signal; a level shifter configured to convert a voltage of the gate timing control signal; and a gate driver configured to receive the gate timing control signal from the level shifter to supply a gate signal to the gate lines, wherein the sensing error processing unit resets the timing controller when the sensing error is detected..
