A data driver for driving pixels in an active matrix organic LED (AMOLED) is provided the data driver includes a plurality of converters configured to convert to analog current signal digital voltage signals in order to drive the pixels to emit light. Each converter has a plurality of current mirror devices configured to generate mirrored current signals by inputting two control signals. Meanwhile, the mirrored current signals can maintain their preciseness even if deviation of the characteristics of the transistors implanted within the current mirror devices occurs during fabricating. |
