Abstract:
An electro-luminescent display comprising:a substrate; a gate line on the substrate; a data line crossing the gate line; a first TFT for selecting an arbitrary pixel by a gate signal, wherein a gate of the first TFT is connected to the gate line; a current mirror for outputting a signal to the arbitrary pixel selected by the first TFT by receiving a data signal from the data line at the same time that the current mirror is being voltage driven, wherein the current mirror includes a second TFT and a third TFT; wherein a drain of the third TFT is connected to a drain of the first TFT, a source of the first TFT is connected to a gate of the third TFT, and the gate of the third TFT is connected to a gate of the second TFT; an electro-luminescent diode connected to the current mirror, wherein the diode is driven by the output signal of the current mirror.
