復旦大學科研團隊成功將顯示器件的制備與織物編織過程相融合,實現(xiàn)了大面積柔性顯示織物和智能集成系統(tǒng)。相關成果近日在線發(fā)表于《自然》雜志。
According to Peng Huisheng, leader of the team and a professor from Fudan’s macromolecular science department, it developed transparent conductive weft fibers and luminescent warp fibers. When woven together, they form micrometer-scale electroluminescent units similar to those on a digital display screen.
科研團隊負責人、復旦大學高分子科學系教授彭慧勝介紹說,團隊研制的“發(fā)光經(jīng)線”和透明的“導電緯線”交織時,可形成微米級電致發(fā)光單元,與數(shù)字顯示屏的電致發(fā)光單元類似。
“發(fā)光經(jīng)線”(luminescent warp fibers),外觀與生活中的尋常紗線類似,但通電后即可發(fā)出明亮的光。“發(fā)光經(jīng)線”的直徑可在0.2毫米至0.5毫米間精確調(diào)控(its diameter can be accurately adjusted between 0.2mm and 0.5mm),賦予了其超細超柔的特性(make it super thin and soft),以此梭織而成的衣服,可緊貼人體不規(guī)則輪廓,并保證輕薄、透氣(light and breathable)。
The team has produced a 6-meter-long and 25-centimeter-wide display textile. It contains 500,000 electroluminescent units and is capable of meeting the resolution requirements of some practical applications.
團隊目前已在實驗室實現(xiàn)長6米、寬0.25米、約含50萬個“像素點”的顯示織物,已能初步滿足部分實際應用的分辨率需求。
【單詞講解】
Display可以用作動詞或名詞,均表示“展示,展現(xiàn),顯示”等意思,比如:public display of affection (PDA)就是“公開展示感情”,即“秀恩愛”,fireworks display(煙花秀),window display(櫥窗展示);display one's skill(展示某人的技能), Toys were displayed in the store window(玩具在商店櫥窗里展示)。而在電視、電腦、手機等電子設備領域,我們更常見的是display screen(顯示屏)。
The brightness between electroluminescent units deviates by less than 5 percent and remains stable even when the textile is bent, stretched or pressed.
交織發(fā)光點亮度變動范圍控制在5%以內(nèi),織物在對折、拉伸、按壓等外力作用下也能保持亮度穩(wěn)定。
It can withstand hundreds of times of machine washing.
可耐受上百次的洗衣機洗滌。
應用前景廣闊
Based on flexible textiles, the team developed an integrated system with functions such as display, sensing and power supply. It shows promising prospects in various areas including real-time positioning, intelligent communication and healthcare.
該科研團隊基于編織方法,還實現(xiàn)了儲能織物、觸摸傳感織物與顯示織物的功能集成系統(tǒng)。該系統(tǒng)在實時定位、智能通訊、醫(yī)療輔助等方面展現(xiàn)出良好應用前景。
People with linguistic disabilities, for instance, could efficiently and conveniently communicate with others in the future by wearing the display fabric.
比如,語言障礙者把“顯示器”穿在身上,就能與人實現(xiàn)高效便捷溝通。
