A light-emitting device avoids a cross-talk phenomenon. The device includes a precharge controlling circuit and a precharge circuit. The precharge controlling circuit provides a precharge controlling signal in accordance with display data input from an external source. The precharge circuit applies a precharge current corresponding to display data and a scan line resistance to the data lines in accordance with the precharge controlling signal transmitted from the precharge controlling circuit. As a result, precharge current is applied to data lines according to a pixel cathode voltage, and thus cross-talk occurs is eliminated or at least substantially reduced in the device.
