Abstract
Provided are an organic light emitting display device and a driving method thereof. The display device includes data lines, first detection lines, first compensation detection circuits, a display driving chip, a compensation chip and a control chip. Each data line is electrically connected to a corresponding first detection line through at least one first compensation detection circuit. The display driving chip sends a reference data signal to the data lines in a detection stage. The compensation chip acquires signals collected by the first detection lines and sends the signals to the control chip in the detection stage. The control chip determines a data signal compensation parameter according to the received signals, and controls the display driving chip to provide a display data signal to the data lines in a display stage according to the data signal compensation parameter.
