一种有源有机发光显示屏(AM-OLED)驱动电路的设计 总被引:2,自引:2,他引:0
介绍一种有源有机发光显示屏(AM-OLED)的驱动电路的设计方法。像素驱动电路采用常用的两管电路结构,依据此像素驱动电路,提出一种利用多晶硅TFT将部分外围驱动电路集成于衬底的设计方法和电路结构。采用互补的多晶硅TFT管设计屏上移位寄存器,传输门等模块,将部分外围驱动电路集成于OLED显示屏的衬底上,极大地减小了数据信号线的数目,降低了屏内信号线布线和屏外驱动电路的复杂程度。进一步讨论了利用复杂可编程逻辑器件(CPLD)设计驱动AM-OLED显示屏专用集成芯片的设计方案。 相似文献

We present a robust filter SQP algorithm for solving constrained optimization problems. This algorithm is based on the modified quadratic programming proposed by Burke to avoid the infeasibility of the quadratic programming subproblem at each iteration. Compared with other filter SQP algorithms, our algorithm does not require any restoration phase procedure which may spend a large amount of computation. The main advantage of our algorithm is that it is globally convergent without requiring strong constraint qualifications, such as Mangasarian–Fromovitz constraint qualification (MFCQ) and the constant rank constraint qualification (CRCQ). Furthermore, the feasible limit points of the sequence generated by our algorithm are proven to be the KKT points if some weaker conditions are satisfied. Numerical results are also presented to show the efficiency of the algorithm. 相似文献

On the Relation between Constant Positive Linear Dependence Condition and Quasinormality Constraint Qualification 总被引:1,自引:0,他引:1
R. Andreani J. M. Martinez M. L. Schuverdt 《Journal of Optimization Theory and Applications》2005,125(2):473-483
The constant positive linear dependence (CPLD) condition for feasible points of nonlinear programming problems was introduced by Qi and Wei (Ref. 1) and used in the analysis of SQP methods. In that paper, the authors conjectured that the CPLD could be a constraint qualification. This conjecture is proven in the present paper. Moreover, it is shown that the CPLD condition implies the quasinormality constraint qualification, but that the reciprocal is not true. Relations with other constraint qualifications are given.This research has been supported by PRONEX-Optimization Grant 76.79.1008-00, by FAPESP Grants 01-04597-4 and 02-00832-1, and by CNPq. The authors are indebted to two anonymous referees for useful comments and to Prof. Liqun Qi for encouragement. 相似文献
