Holst中心和IMEC推出下一代柔性O(shè)LED顯示器

近日，Holst中心和IMEC推出其下一代的柔性O(shè)LED（有機(jī)發(fā)光二極管）顯示器的新研究方案，基于其成熟的技術(shù)跟蹤記錄，并在相關(guān)領(lǐng)域如有機(jī)氧化物晶體管和柔性O(shè)LED照明等現(xiàn)有合作研究中伙伴的良好基礎(chǔ)，新方案的主要目標(biāo)是建立一個經(jīng)濟(jì)可伸的路線，以及大批量的柔性有源矩陣 OLED顯示器的制造。共享程序與其合作者將匯集來自整價值鏈的解決方案，如高分辨率，低功耗，大面積，靈活性和重量輕等。

最先進(jìn)的 OLED顯示器小巧并且使用靈便，應(yīng)用在智能手機(jī)和平板電腦中，它們的特點(diǎn)與傳統(tǒng)的LCD由OLED像素發(fā)出只在激活時更加激烈的黑色形成強(qiáng)烈的反差。此外，OLED具有更快的響應(yīng)時間，消除圖像的滯后性。同時，基于配置文件OLED的功率消耗更低，相比傳統(tǒng)的LCD能夠提供更好的對比度和可視角度。OLED在設(shè)計上和較少的組件相比LCD也簡單得多，并在大量的程序中降低成本。

The ambition of the new program is work towards flexible, high-resolution OLED displays. The program will tackle the individual challenges towards the next-generation of OLED displays: a mechanically flexible encapsulation film and TFT backplane; and printed, high-efficiency OLEDs. New materials and processes that allow for cheaper production, better quality, lower power, more robustness and more flexibility will be developed. Moreover, the design of the drivers, pixel circuits and TFT backplane matrix will be reconsidered as increasing display area influences the amount of pixels-per-inch or the refresh rates. Finally the program scope includes the development of new manufacturing equipment such as fine patterning equipment for backplanes and tools for integrated roll-to-roll manufacturing.?

Gerwin Gelinck (Holst Centre), Program Manager of the OLED Display Program: ” Holst Centre and its partners continuously look for new application domains for the generic flexible electronic technologies that have been developed. This ensures our research stays tangible, application-oriented and relevant for industry and society. Flexible displays represent an enormous economic and technical opportunity for flat panel manufacturers and its supply chain. As such they are seen as an attractive landing place for many new technologies. Flexible displays are therefore becoming a top priority research effort for many companies worldwide, including many of our current industrial partners.”?

Paul Heremans (imec), Program Manager of the OLED Display Program: “With this program in mind, we already have been working more and more towards integrating separate building blocks and have realized OLED displays using both organic and metal oxide TFT backplanes. Thin, plastic substrates were used, and the displays were fully encapsulated using our state-of-the-art barrier technology. Part of this was done with other research institutes in a European project called FLAME, but we could really pull this off because of intense collaboration with some of our industrial partners. We will demonstrate some of these display prototypes in 2012.”
