近期而言,主動矩陣式有機發光二極體(AMOLED)由於其非常優異的特性而受到市場上相當的矚目,例如,高亮度、輕質量、快的反應速度和廣視角等等的優勢。低溫多晶矽薄膜電晶體是被廣泛的應用於當主動矩陣式有機發光二極體中設計的驅動元件由於其相當高的電流驅動能力。當電子移動率較高時,在一個給定的畫素設計面積時將可以獲得較大的開口率,或是在一個給定的開口率時將可以獲得較高的解析度,於是可以用來設計更高畫質的顯示器。更可以用來將原有的一些外部電路進一步的整合於面板內,制造出更輕質便利且美觀的顯示器。
    然而,在實際上,低溫多晶矽薄膜電晶體因為在製程中經過分子雷射的退火再結晶會導致一些電性上的不均勻,這是一個非常嚴重且不可避免的問題。在傳統的2T1C畫素電路中,便可以很清楚的發現由於以上電性的問題造成全畫面影像的不均勻和品質的衰退。且當有機發光二極體經過長時間的操作,會使其造成內部結晶造成一些亮度衰退,而這也會造成顯示器畫面品質的影響。
    因此,我們發表了三個新型的電壓編碼補償的畫素電路,二個5T1C與一個6T1C,並且這三個電路都可以針對以上的電性衰退進行有效的補償。而電路也已經經由AIM-SPICE軟體的驗證和模擬。
    在第一個5T1C畫素電路中,經由軟體的模擬驗證可得知其平均電流錯誤率在驅動元件臨界電壓偏移±0.33伏特下約為0.5%,其平均電流錯誤率在發光元件臨界電壓偏移+0.33伏特下約為10%,還有其電流平均錯誤率在IR DROP為0.3伏特時為8%,尤以上數據顯示不管驅動元件和發光元件已經發生衰退且電性不均勻情況下,其輸出的有機發光二極體電流可以穩定的被控制。
    在第二個5T1C畫素電路中,經由軟體的模擬驗證可得知其平均電流錯誤率在驅動元件臨界電壓偏移±0.33伏特下約為0.8%,其平均電流錯誤率在發光元件臨界電壓偏移+0.33伏特下約為4.7%,還有其電流平均錯誤率在IR DROP為0.3伏特時為5.8%,尤以上數據顯示不管驅動元件和發光元件已經發生衰退且電性不均勻情況下,其輸出的有機發光二極體電流可以穩定的被控制。
    在6T1C畫素電路中,經由軟體的模擬驗證可得知其平均電流錯誤率在驅動元件臨界電壓偏移±0.33伏特下約為3.7%,還有其電流平均錯誤率在IR DROP為0.3伏特時為8.9%,尤以上數據顯示不管驅動元件和發光元件已經發生衰退且電性不均勻情況下,其輸出的有機發光二極體電流可以穩定的被控制。
    由以上的結果顯示,由於有機發光二極體是一個電流控制元件,所以其發光亮度和輸出的電流是呈現正相關對比的,我們可以得知經由去補償驅動元件和發光元件的電性而達到了預期的顯示畫面品質。因此,我們肯定的相信在此論文所發表的兩個新型畫素電路設計是有著相當不錯的穩定電流驅動能力且也是相當適合於應用在大尺寸和高解析度的主動式有激發光二極體顯示器面板中。
Active matrix organic light-emitting diode (AMOLED) has recently attracted much attention due to its high brightness, light weight, fast response-time, and wide viewing angle. Low-temperature polycrystalline-silicon (LTPS) thin-film transistors (LTPS-TFTs) have been widely considered as pixel elements for AMOLED due to their high current-driving capability. The high electron mobility of LTPS-TFTs can achieve larger aperture ratio for a given pixel size of AMOLED and a higher resolution display to get the better image quality. Furthermore, a very light-weight display with few external interconnections is possible, because the peripheral circuits and the pixel driver circuits both using LTPS-TFTs can be integrated onto the same substrate.
However, the LTPS-TFTs still have the issue of non-uniformity of threshold voltage due to the excimer laser annealing (ELA) process. In the conventional two-TFTs pixel circuit for AMOLED, various threshold voltages of driving TFT (DTFT) cause the non-uniform gray-scale over the display area. In addition, the long time operation for OLED will cause the brightness to drop off as the OLED threshold voltage degradation.
Therefore, in order to overcome the above-mentioned issues, we have proposed three novel voltage-modulated structures for AMOLED pixel circuit as 5T1C, 5T1C* and 6T1C. These circuits can compensate both the DTFT threshold voltage deviation and the OLED degradation. The proposed circuits are also verified by SPICE simulator.
In the 5T1C simulation, results show that the average OLED current error rate under ΔVTH = ±0.33 V is 0.5%, the average OLED current error rate underΔVTH_O = +0.33 V is 10% and the average current error rate under IR Drop voltage = 0.3 V is 8%. It can effectively reproduces almost identical OLED current regardless of the DTFT threshold voltage deviation and OLED degradation.
In the 5T1C* simulation results show that the average OLED current error rate under ΔVTH = ±0.33 V is 0.8%, the average OLED current error rate underΔVTH_O = +0.33 V is 4.7% and the average current error rate under IR Drop voltage = 0.3 V is 5.8%. It can effectively reproduces almost identical OLED current regardless of the DTFT threshold voltage deviation and OLED degradation.
In the 6T1C simulation results show that the average OLED current error rate under ΔVTH = ±0.33 V is 3.7%, and the average current error rate under IR Drop voltage = 0.3 V is 8.9%. It can effectively reproduces almost identical OLED current regardless of the DTFT threshold voltage deviation and OLED degradation.
The above results show that the image non-uniformity of AMOLED can be effectively improved at the same time by compensating the DTFT threshold voltage deviation and the OLED threshold voltage degradation. Thus, we believe that the proposed pixel circuit design has very high driving capability and is a promising candidate for the large size, high resolution AMOLED panels.
