本篇論文將主動式有機發光面板(AMOLED)畫素驅動電路用電晶體小訊號等效模型結合類比濾波電路系統模擬有機發光二極體(OLED)負載的電流突波現象。從先前實驗量測結果顯示,OLED負載電流訊號有明顯的突波波形產生,實驗結果透過傅立葉轉換(FFT)後,得到頻域下突波分佈於較高頻位置,此結果與濾波電路系統濾除雜訊時,頻域下雜訊分佈於高頻位置相似,因此藉由模擬濾波電路系統加入OLED負載前端與後端的波形比較,並運算有效值(RMS值)定量分析其變化。模擬結果顯示RLC類比濾波電路使OLED負載電壓有效值下降25%、電流有效值下降16%、實功率有效值下降55%、虛功率有效值下降37%;LC濾波電路則使OLED負載電壓有效值下降2%、電流有效值下降1.5%、實功率有效值下降30%、虛功率有效值下降2.5%;因此類比LC濾波電路掛載在前端,電壓與電流有效值改變較小,實功率與虛功率有效值減少較多。

This thesis research is to investigate the feasibility of suppressing the current surge signal occurred in 2T1C AMOLED pixel circuitry by applying analog filter circuitry in terms of computer simulation. The current waveform of the active-matrix OLED load in previous study disclosed an inevitable surge signal distributed in higher frequency zone after analyzed by using Fast Fourier Transform (FFT). The effectiveness of applying various analog filter in pixel circuitry is quantitatively analyzed by using the RMS values calculated from various waveforms. Our simulation results reveal that the RMS values of the voltage, current, real power, and reactive power decrease in 25%, 16%, 55%, and 37% respectively after applying RLC analog filter in pixel circuitry. The RMS values of the voltage, current, real power, and reactive power decrease in 2%, 1.5%, 30%, and 2.5% respectively after applying LC analog filter in pixel circuitry.
