The driving scheme can provide different current levels for the OLED while compensating for long-term (and gradual) instabilities caused by material defect metastability which will make it amenable for use in AMOLED displays. Moreover, since the threshold voltage is known in this method, it can be used to compensate for the time-dependent errors of the charge injection and clock feed-through effects. Therefore, the error for a 3V shift in the VT of T1 is almost zero. More importantly, it has low power consumption because the line capacitance is charged just one time during the programming cycle. For example, the total power consumption of a QVGA array (240*320) is expected to be less than 1.5W.","PeriodicalId":131387,"journal":{"name":"The 3rd International IEEE-NEWCAS Conference, 2005.","volume":"16 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123263796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through analyses made at synthesis and silicon measurements levels, it is shown that the best results are obtained by optimizing the SOI technology for the targeted power supply voltage. At the nominal 1.2V supply voltage, this is achieved by setting a higher threshold voltage V/sub T/ to limit the cut-off currents. The power gains are in the order of 25% to 30% for the same performance. To further reduce the power dissipation, targeting the ultra-low-voltage range (0.5V) is very attractive when performance is not an issue. Using low-V/sub T/ SOI transistors allows significant gains in terms of speed and power. The power-delay product of a 16-bit multiplier is improved by a 2.4 factor.","PeriodicalId":131387,"journal":{"name":"The 3rd International IEEE-NEWCAS Conference, 2005.","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122277021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
