Abstract:
1. A method of driving a light emitting device comprising: selecting a first gate signal line electrically connected with a first gate signal line driver circuit to turn ON first and second TFTs; flowing a first current corresponding to an image signal into a source signal line, the first TFT, and a third TFT, wherein a voltage between a gate electrode of the third TFT and a source region of the third TFT is V de-selecting the first gate signal line to turn OFF the first and second TFTs, wherein the V selecting a second gate signal line electrically connected with a second gate signal line driver circuit to turn ON a fourth TFT; and flowing a second current corresponding to the V wherein the third TFT is operated in a saturation range during a period when the first current or the second current flows into the third TET.
