Description
しかし大抵の場合、表示する画像によって画素毎に表示される階調が異なり、そのため各画素の発光素子の劣化に差が出てしまい、輝度にばらつきが生じる。そして、電圧または電流を供給するための電源を各画素に対応して設けるのは現実的ではないので、全ての画素または幾つかの画素毎に電圧または電流を供給するための共通の電源を設けている。そのため、劣化に伴う発光素子の輝度の低下を補うために、共通の電源から供給される電圧または電流を単純に大きくすると、該電圧または電流が供給された画素全てにおいて平均的に発光素子の輝度が高くなるが、各画素毎の発光素子の輝度のばらつきは解消されない。
本発明の発光装置によって、発光期間の差による発光素子の劣化を回路側で補正し、輝度ムラのない均一な画面の表示が可能な発光装置を提供することが出来る。
本実施例では、本発明の発光装置の補正部における、映像信号の補正方法について説明する。
画素201は、その発光期間または階調数の累積したデータから、画素202に比べて画素203との劣化の進み具合の差が大きいと予測されるため、画素202よりも大幅な階調数の補正がなされる。
(T.Tsutsui, C.Adachi, S.Saito, Photochemical Processes in Organized Molecular Systems, ed.K.Honda, (Elsevier Sci.Pub., Tokyo,1991) p.437.)
そして、半導体膜780は、第3濃度の一導電型不純物領域783と、チャネル形成領域784を有している。
がオフ電流の低減に効果的である。
従って、LDD領域937は完全にゲート電極に重ねてしまい、極力抵抗成分を少なくすることが望ましい。即ち、いわゆるオフセットはなくした方がよい。
本実施例の場合、発光層45で生成された光は上面側に向かって(TFTの上方に向かって)放射されるため、陽極は透光性でなければならない。透明導電膜としては酸化インジウムと酸化スズとの化合物や酸化インジウムと酸化亜鉛との化合物を用いることができるが、耐熱性の低い発光層や正孔注入層を形成した後で形成するため、可能な限り低温で成膜できるものが好ましい。
