近幾年來,光電資訊產業發展蓬勃,對於更輕薄的平面顯示器之需求更是日益增加,因此在可撓曲塑膠基板上製作有機發光二極體元件(OLED)無疑是下一世代平面顯示器的主流。目前許多圖案製作技術當中,壓印技術(imprinting lithography)可以改善光學微影蝕刻的多項缺點,而其優點在於設備與操作成本低、生產彈性大、可做立體的蝕刻技術;故本研究中將利用壓印技術應用於四吋可撓曲OLED面板的製作,此外由於OLED非常怕其水氣與氧氣的侵入而造成元件的衰退,所以也對OLED的封裝膜進行探討。
此外,為解決熱壓印(hot embossing)技術中殘留層太厚及壓印時間過長的問題而開發了逆式壓印(reversal imprinting),其是利用具有雙官能基之界面活性劑(surfactant)將所使用的阻劑完全填入模版的凹槽內部,再利用基板與之緊密貼合,最後模板的圖案可忠實的轉移至基板上,目前480μm~100nm都已經可以完整轉印出來。
以上述的壓印方式來製備OLED顯示面板,並利用電漿聚合的方式沉積MMA/HMDSO多層複合封裝層於其元件上,其封裝與未封裝的元件相比具有4.2倍壽命(Life-time)的延長效果 ,且經由定電壓隨時間變化,利用OM去記錄其影像,可發現在未封裝時元件在一小時之後,元件皆有因水氣經電化學反應而產生氣泡(H2)所造成的暗點,且幾乎佈滿整個元件,而封裝後的元件在五天的測試後只有因TPD結晶所造成暗點擴大的現象,完全無氣泡產生。所以在以複合封裝膜保護的元件下,可以增加其元件的穩定性,且可有效的阻抗水氣的侵入。
Recently, optoelectronic industry developed rapidly to increase the requirement of thinner and lighter flat panel display. Undoubtedly, the fabrication of organic light emitting diode (OLED) on flexible plastic substrate was the major technique in the next plat display generation. To date, many patterning techniques have been developed and imprinting technique was one of these. Imprinting lithography has many advantages including low cost, large manufacturing elasticity and ability of 3-D construction. In this study, the imprinting lithography was employed to manufacture 4” flexible OLED display. Additionally, OLED devices were easily affected by the humidity and oxygen and decayed the device performance. Therefore we also studies the encapsulation technique for OLED device.
In order to solve the thick residual layer and the long time process in hot embossing lithography, the reversal imprinting was developed in this study. The principle of reversal imprinting is on using two functional groups surfactant to modify the mold surface. The hydrophilic side would pull the resist into the groove of the mold. Finally, the treated mold need to give a perfect contact with the substrate. Then the conformal pattern can be transferred. Now, the pattern of 480μm to 100nm can be successfully transferred.
The OLED display was fabricated by reversal imprinting and MMA/HMDSO muti-layer were deposited by using plasma poly -merization to passivate OLED devices. The Life-time of passivated device protend 4.2 times than un-passivated one, and the device was test under the constant voltage and the morphology was recorded by optic microscopy (OM). After one hour, the dark spots were observed for devices without passivation layer and cover full of the device. The dark spots were estimated by electrical chemical reaction of water vapour, and the bubbles (H2) would form. However, the passivated device can be stored at constant voltage without any bubble formation after five days. A few dark spots were observed by OM and these spots formed by TPD crystallization. Therefore the muti-layer thin film could effectively protect the device to inhibit the water or oxygen diffusion.
