Description
図1は、実施の形態1における画像表示装置100の構成図である。画像表示装置100は、入力した画像信号を補正する画像信号補正回路50と、補正された画像信号を表示する画像表示部10とを備える。
(条件2)基準電圧Vref<低圧側電圧Vss+電圧Vled+閾値電圧Vth
本実施の形態においては、基準電圧Vref=1(V)、初期化電圧Vint=−1(V)である。しかしこれらの数値は表示装置の仕様や各素子の特性に応じて変動し、駆動電圧は表示装置の仕様や各素子の特性に応じて上記の条件を満たす範囲で最適に設定することが望ましい。
時刻t1において、制御信号CNT22(i)、CNT24(i)をローレベルにしてトランジスタQ22、Q24をオフ状態とするとともに、制御信号CNT21(i)、CNT23(i)、CNT25(i)をハイレベルにしてトランジスタQ21、Q23、Q25をオン状態とする。するとトランジスタQ25を介して節点Tp1に基準電圧Vrefが印加され、トランジスタQ21を介して節点Tp2にも基準電圧Vrefが印加される。
時刻t2において制御信号CNT23(i)をローレベルにしてトランジスタQ23をオフ状態とし、制御信号CNT24(i)をハイレベルにしてトランジスタQ24をオン状態とする。すると駆動トランジスタQ20のゲート・ソース間には閾値電圧Vthよりも高い第2コンデンサC22の端子間電圧(基準電圧Vref−初期化電圧Vint)が印加されているために駆動トランジスタQ20に電流が流れる。しかし有機EL素子D20のアノードの電圧は基準電圧Vrefから閾値電圧Vthを減じた電圧よりもさらに低く、条件2に示したように、基準電圧Vref−閾値電圧Vth<低圧側電圧Vss+電圧Vledであるので、有機EL素子D20には電流は流れない。そして駆動トランジスタQ20に流れる電流により第2コンデンサC22の電荷が放電され、第2コンデンサC22の端子間電圧が低下しはじめる。しかし第2コンデンサC22の端子間電圧は依然として閾値電圧Vthより高いので駆動トランジスタQ20には電流が減少しつつも流れ続ける。そのため第2コンデンサC22の端子間電圧は徐々に低下し続ける。このようにして第2コンデンサC22の端子間電圧は閾値電圧Vthに漸近する。そして第2コンデンサC22の端子間電圧が閾値電圧Vthに等しくなった時点で駆動トランジスタQ20に電流が流れなくなり、第2コンデンサC22の端子間電圧の低下も止まる。このように第2コンデンサC22は、対応する駆動トランジスタQ20の閾値電圧Vthを補正する補正コンデンサである。
時刻t3において制御信号CNT25(i)をローレベルにしてトランジスタQ25をオフ状態とし、制御信号CNT24(i)をローレベルにしてトランジスタQ24をオフ状態とする。その後、制御信号CNT22(i)をハイレベルにしてトランジスタQ22をオン状態とする。すると節点Tp1が画像信号電圧Vsg(j)となり、第1コンデンサC21の端子間は電圧(画像信号電圧Vsg−基準電圧Vref)に充電される。以下では、この電圧(画像信号電圧Vsg−基準電圧Vref)を画像信号電圧Vsg’と記載する。
時刻t4において、制御信号CNT22(i)をローレベルにしてトランジスタQ22をオフ状態とし、制御信号CNT21(i)をローレベルにしてトランジスタQ21をオフ状態とする。すると節点Tp1〜Tp3は一旦フローティング状態となる。そして制御信号CNT24(i)をハイレベルにしてトランジスタQ24をオン状態とする。すると、駆動トランジスタQ20のゲート・ソース間には電圧(画像信号電圧Vsg’+閾値電圧Vth)が印加されているので、ソース電圧が上昇して、駆動トランジスタQ20のゲート・ソース間電圧に応じた電流を有機EL素子D20に流す。このときの電流Iは、I=μ・k・(VGS−閾値電圧Vth)^2=μ・k・画像信号電圧Vsg’^2となり、閾値電圧Vthを含まない。ただしVGSはゲート・ソース間電圧であり、μは駆動トランジスタの移動度である。またkは、駆動トランジスタのゲート絶縁膜容量C、チャンネル長L、チャンネル幅Wに依存して決まる係数であり、k=C・W/2Lで表される。
