【摘要】：在硅基OLED微顯示器中,為了解決很小的像素驅(qū)動(dòng)電流的難題,論文提出了一種像素電路。此像素電路由2個(gè)PMOS、2個(gè)NMOS、1個(gè)存儲(chǔ)電容、1個(gè)OLED和4根信號(hào)線組成。并且利用HSPICE基于TSMC 0.35μm CMOS 5V工藝的參數(shù)進(jìn)行了仿真驗(yàn)證。在此像素電路中,當(dāng)OLED發(fā)光時(shí)流過(guò)OLED的電流是恒定的,并且通過(guò)控制OLED的發(fā)光時(shí)間來(lái)實(shí)現(xiàn)不同的灰度。此像素電路完全由數(shù)字信號(hào)控制,能實(shí)現(xiàn)精確的灰度調(diào)節(jié)。通過(guò)6個(gè)子場(chǎng),實(shí)現(xiàn)了21級(jí)灰度,進(jìn)而論證了實(shí)現(xiàn)64級(jí)灰度(0~63)的可能性。當(dāng)OLED發(fā)光時(shí),流過(guò)的恒定電流是35.3nA。
[Abstract]:In order to solve the problem of small pixel driving current in silicon-based OLED microdisplay, a pixel circuit is proposed in this paper. The pixel circuit consists of two PMOS,2 NMOS,1 memory capacitors, one OLED and four signal lines. The parameters of HSPICE based on TSMC 0.35 渭 m CMOS 5V process are simulated and verified. In this pixel circuit, the current flowing through OLED is constant when OLED emits light, and different grayscale is realized by controlling the luminous time of OLED. This pixel circuit is completely controlled by digital signal and can realize accurate gray adjustment. Through six subfields, 21 grayscale is realized, and the possibility of realizing 64 grayscale (0 鈮，
