Display panel, light emitting display device using the same, and driving method thereof
Abstract:
A light emitting display device including data lines, signal lines, pixel circuits, a data driver, and a precharger. Each pixel circuit includes a first switch, a transistor, a capacitor, and a light emitting element. The precharger supplies a precharge current of X times a data current to a corresponding data line in response to a control signal. When the first switch transmits the data current provided from the corresponding data line in response to a first level scan signal while the corresponding data line is precharged, a voltage corresponding to the data current is charged in the capacitor. A current corresponding to the charged voltage is supplied to the light emitting element through the transistor in response to a second level scan signal, and the light emitting element emits light.
