Electro-luminescent display including a current mirror |
摘要 |
An electro-luminescent display includes a current mirror for supplying uniform drive currents to the electro-luminescent diodes of the electro-luminescent display. The current mirror is not effected by the various threshold voltages VTH of the switching devices in the electro-luminescent display so that uniform current is output to the electro-luminescent diodes throughout the display. The electro-luminescent display includes a gate line, a data line intersecting the gate line, a first TFT for selecting an arbitrary pixel by a gate signal from the gate line, wherein a gate of the first TFT is connected to the gate line, and a current mirror for outputting a signal to an arbitrary pixel selected by the first TFT by receiving a data signal from the data line at the same time the current mirror is being driven by applied voltage. The current mirror includes a second TFT and a third TFT, and an electro-luminescent diode driven by the signal output from the current mirror.
