Description
Ids=kμ(Vgs−Vth)2=kμ(Vsig−ΔV)2
上記式において、k=(1/2)(W/L)Coxである。ここでWはドライブトランジスタのチャネル幅、Lは同じくチャネル長、Coxは同じく単位面積あたりのゲート容量を表している。この特性式から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圧Vsigによって決まる。換言すると、発光素子ELは映像信号Vsigに応じた輝度で発光する事になる。その際Vsigは帰還量ΔVで補正されている。この補正量ΔVは丁度特性式5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Vsigのみに依存する事になる。
