Abstract: Disclosed an organic light-emitting diode display device in which the number of signal lines is minimized by sharing a predetermined signal line between adjacent pixels in a display panel having a plurality of signal lines formed therein, thereby improving an aperture ratio. The organic light-emitting diode display device includes a display panel defining pixels, a gate driver, a data driver, a multiplexer (MUX) electrically connecting an output terminal of the data driver and the pixels into a 1:1, 1:N (N is a natural number) or N:N structure, and a timing controller. Accordingly, the MUX is provided between the data driver and the pixels, and each pixel and signal lines are selectively connected through the MUX, so that it is possible to reduce the number of Integrated chips (ICs) provided by allowing a compensation circuit built in the data driver.

Abstract: A light emitting display apparatus includes a pixel driving circuit including a driving transistor and an anode reset capacitor connected to a gate of the driving transistor and a light emitting device configured to emit light with a current supplied through the driving transistor. An anode reset period, where a data voltage is not supplied to the driving transistor, is between refresh periods where the light emitting device emits the light with the data voltage supplied to the driving transistor, and an anode reset voltage supplied to the anode reset capacitor in the refresh period is higher than an initial voltage which is input to the gate of the driving transistor in the refresh period.
