Description
Ids=(1/2)μ(W/L)Cox(Vgs−Vth)2・・・式1
このトランジスタ特性式1において、Vgsはソースを基準としてゲートに印加されるゲート電圧を表わしており、Vthはトランジスタの閾電圧である。又μはトランジスタのチャネルを構成する半導体薄膜の移動度を表わしている。その他Wはチャネル幅を表わし、Lはチャネル長を表わし、Coxはゲート容量を表わしている。
Ids=kμ(Vgs−Vth)2=kμ(Vsig−ΔV)2・・・式2
上記式2において、k=(1/2)(W/L)Coxである。この特性式2からVthの項がキャンセルされており、発光素子ELに供給される出力電流IdsはドライブトランジスタTrdの閾電圧Vthに依存しない事が分かる。基本的にドレイン電流Idsは映像信号の信号電位Vsigによって決まる。換言すると、発光素子ELは映像信号の信号電位Vsigに応じた輝度で発光する事になる。その際Vsigは負帰還量ΔVで補正されている。この補正量ΔVは丁度特性式2の係数部に位置する移動度μの効果を打ち消すように働く。したがって、ドレイン電流Idsは実質的に映像信号の信号電位Vsigのみに依存する事になる。
