亲爱的读者和显示朋友们:我谨代表美国信息显示协会项目委员会,热烈欢迎参加5月11日至16日在加州圣何塞举办的第62届显示周。我很高兴与大家分享本次活动精彩节目的一些亮点。由于全球显示行业和学术界的参与创历史新高,研讨会计划已增至98场会议,因此需要在5月16日星期五全天举行会议,以适应增加的论文数量。研讨会涵盖了一系列技术专业,您将在下面的预览文章中看到这些专业。这些会议包括常规、受邀和最新新闻,将报道行业的进展和创新,包括下一代技术和显示、传感和成像的应用,仅举几例。四个专题将突出选出具有当前战略重要性的领域。“包括成像机器学习在内的人工智能”将重点介绍改变显示设计、制造和新应用的新兴软件技术。“超高带宽显示数据传输和处理”将解决未来沉浸式显示的关键挑战,具有更高的分辨率和刷新率,以及扩展现实、全息和光场显示中的3D应用。2025年,“新兴应用的异构集成”将包括平板显示器和半导体制造之间的协同效应,为高性能电子封装,下一代显示器和非显示应用提供新的机会。“可持续显示和绿色技术”将聚焦全球在产品制造和生命周期中最大限度地减少对环境的影响的努力,使显示的光明未来惠及每一个人,每一代人。其他学习和交流的机会包括短期课程、研讨会,以及2025年新推出的“展示101”计划,该计划是为进入该领域的人设计的。周一的活动将包括年度商业会议,重点关注供应链和商业主题,以及2025年与OpenCV合作举办的计算机视觉和人工智能会议,以补充研讨会中的人工智能/机器学习领域。周二,一定要参加备受期待的主题演讲和展览厅的开幕式,包括I-Zone和新的XR馆(详细信息请访问www.displayweek.org)。感谢我们的团队在幕后为大家带来这档精彩的节目。许多志愿者、项目委员会和专题小组的热情成员、SID执行委员会和总部团队使这一切成为可能。作为2025年技术计划主席,我很荣幸和高兴与扩展团队合作,与众多作者互动,并帮助汇集来自全球显示社区的令人兴奋的进步和创造力。因此,我衷心建议参加这次会议。特别是对于学生,我希望你们能充分利用注册折扣,并利用这个机会了解美丽的展示世界,帮助我们创造未来。对于任何参加展示周的人来说,这可能是相当令人敬畏的。数百场演讲和演示被分配到指定的房间和时间,在令人印象深刻的展览区内,无论是在私人谈话还是在目睹I-Zone的可能性时,想法都层出不穷。但是所有这些创新和神奇,如果你愿意的话,都有一个起点,在那里,项目主席和一般主席、研讨会协调员、小组委员会主席和SID员工聚集在一起讨论如何将各个部分落实到位。见证论文的选择过程是相当迷人的。数十名专门的展示专家聚集在一起,审查数百篇论文,并讨论哪些主题不仅最有新闻价值或最感兴趣,而且对行业有很大影响。考虑到这一点,本文重点介绍了显示技术方面正在进行的一些最佳工作,这些工作将于5月11日至16日在加利福尼亚州圣何塞举行的2025年显示周上展出。虽然不是包罗万象,但它的目的是为那些可能对所有的产品感到有点不知所措的与会者提供一个研讨会指南。将介绍几个扩展的重点领域,以探索显示行业快速发展的发展,这些发展正在推动突破性的创新和令人兴奋的新技术的出现。今年,技术研讨会将破纪录地举办98场会议,由他们的技术重点组织。 该领域的一些热门话题将集中在薄膜晶体管(TFT)技术上,包括堆叠垂直氧化TFT,多晶氧化TFT的进展,以及用于IT有源矩阵OLED (AMOLED)应用的高迁移率金属氧化物TFT的开发。其他产品将包括驱动微型led显示器的像素电路和基于单独驱动像素方案的低功耗OLED显示技术。令人感兴趣的报告包括Mamoru Furuta等人(高知工业大学/东京电子技术解决方案)的报告,该报告将展示无氢非晶氧化物半导体TFT的概念,以解决相关的不稳定性(70.3)。shouzen Chang等人(Powerchip Semiconductor Manufacturing)将讨论通过在堆叠上蒸发OLED来制造OLED显示器,显示器显示正常运行(47.2)。Masataka Nakada等人(半导体能源实验室)将介绍水晶InOx作为底板中低温多晶氧化物(LTPO)的有前途的替代品,以及作为更大玻璃基板生产线的应用(77.2)。两个著名的海报是Sanghyun Heo等人(三星显示器)提出的7T1C像素电路,以尽量减少驱动晶体管的电流偏差(P.8),另一个是Jin Jang等人(先进显示研究中心)讨论的金属绝缘体半导体铁电(MISF)结构TFT,用于可拉伸的backplanes (P.150)。APV收到了许多关于增强现实(AR)和虚拟现实(VR)的高质量论文,这些论文研究了如何用新的光学技术改善视觉体验。一些值得注意的演讲将由Zong Qin等人(中山大学)进行,将讨论2D Alvarez透镜来纠正散焦和散光(58.4),另一个由Chang-Yeong Han等人(三星显示器)进行,将重点放在低持久性显示的运动伪影的整体评估(58.1)。此外,还将有几场关于色彩显示的演讲,包括应用色彩师Jack Holm (Tarkus Imaging)的邀请演讲,他将讨论创意专业人士如何使用宽色域(WCG)和高动态范围(HDR)以及可能的应用问题(66.1)。其他演讲将深入探讨其中一些主题,包括Farnaz Agahian和Dale Stolitzka(三星显示器美国实验室)(66.2)在自然界中出现的一些超饱和颜色的频率,以及人与人之间的差异如何与显示原色相互作用,从而在WCG显示器上产生不同的个人色彩体验,由Yoojin Kang等人(LG显示器)(66.4)。该领域将涵盖诸如全息光学元件(HOE), AR/VR光学,波导,全息薄膜,人工智能(AI)和机器学习(ML)以及微显示器(eyeware)等热门话题。偏振体全息为基于波导的AR显示提供了更高的光学效率、更宽的光谱和角带宽以及更低的彩虹效应等优点。然而,制造过程是一个瓶颈。在受邀演讲中,Cesar Clavero等人(Intermolecular/Merck KGaA)将讨论如何建立可重复的高通量沉积和图案工艺,以清除大规模生产的障碍(24.1)。丛宁等人(京东方科技集团)将讨论提高像素密度和降低单芯片成本作为微led进入主流产品的途径。它们将采用0.9英寸尺寸的6020 ppi和4000 × 4000分辨率的微型led显示屏,旨在展示尺寸,亮度和高像素密度(17.4)。Yuki Tamatsukuri等人(半导体能源实验室)将介绍90hz, 5009 ppi OLED显示器的开发,该显示器采用OLED/OS/Si结构制造,其中像素阵列和驱动器是单片堆叠的。这将使AR和VR设备具有更少的集成电路(ic)数量和更小的外壳(17.2)。其他演讲将集中在人工智能的大规模生产,显示器和光学的完美融合,以及如何处理数据时的速度。这些主题将重点介绍汽车领域的几项创新,其中许多创新侧重于可达性和安全性。平视显示器(hud)和透明显示器是今年的大热门,它们都能方便地在驾驶时消化信息。对比度改善、透明图像质量和局部调光等方面的发展也将成为重点。Markus Weber等人(大陆汽车技术公司)将引入一种新的仪表板机械扭转灵敏度指

Kim表示,目前的背板技术低温多晶硅和氧化物(LTPO)结合了氧化物和低温多晶硅(LTPS) tft的优势,将氧化物用于低功耗开关,多晶硅用于高速开关。然而,随着行业向更大的OLED面板(如8.6代IT OLED)发展,Kim认为LTPS在更大玻璃尺寸的统一加工方面面临挑战。“为了解决这个问题,”Kim说,“我们的实验室正在研究高迁移率氧化物tft,以潜在地取代大型显示器中的LTPS。如果成功,这项创新可能会导致完全基于氧化物的背板技术,实现更高效和可扩展的显示器。我们的目标是开发可靠的氧化物tft,并探索新的设备概念,以推动未来的技术,无论是在显示器还是其他领域。”工程项目面临着领先院校共同面临的挑战。一个重要的问题是空间和设施有限,无法满足对先进研究和教育日益增长的需求。此外,随着许多公司寻求尖端技术和合作,满足所有这些需求一直具有挑战性。根本没有足够的学生和实验室。为了解决这些问题,该大学已经投资扩大基础设施和升级研究设施,包括在松岛开发国际校园。此外,还努力确定伙伴关系的优先次序,并简化研究重点领域,以确保在这些限制条件下取得有影响力的成果。虽然延世大学是私立大学,但资金并不是问题。Kim表示:“作为韩国领先的私立大学,我们在获得学费、捐赠和研究补助金等各种来源的支持的同时,独立运营。虽然项目资金可能会有所不同,但延世大学在通过与行业领导者和政府拨款的合作关系为其工程和显示器相关项目争取资源方面有着良好的记录。特别是,显示技术被指定为12项核心技术之一,预计今后政府的投资将会增加。这种支持使延世大学能够继续推进其在这些关键领域的研究和教育。”该学院与领先企业的合作关系有助于获得支持,从而进一步推动研究并帮助招收新生。例如,LG显示器目前支持10多个不同的研究实验室。三星电子为了培养未来人才,与延世大学共同设立了综合显示工程系。同样,三星显示器公司也资助了一个专门的研究中心,以推进尖端的显示技术。此外,个别实验室与各种显示公司在私人项目上合作,解决特定行业的挑战(图3)。根据Kim的说法,该大学在显示研究方面的成功源于战略投资和举措,包括前面提到的集成显示工程系的建立,该系提供与显示研究和工程相关领域的本科和研究生课程。该大学还通过产学研中心与全球展示领导者合作,促进年度知识交流,为学生提供有价值的行业见解。这些公司的许多员工也回到延世大学攻读高等学位,进一步加强了延世大学与私营企业之间的联系。这种合作周期巩固了延世作为显示技术领导者的声誉,促进了创新并推动了该领域的进步。这些合作导致了几项与显示技术相关的专利,尽管没有商业化,也没有直接导致创业公司或独立公司。然而,延世大学与LG显示器公司合作设立了一个专门部门,作为就业相关计划的一部分。该项目为学生提供了与行业相关的教育和机会,许多毕业生在完成学业后在公司获得了职位。延世大学与12家不同科学学科的专业专利公司签订了协议,以管理和商业化知识产权,确保研究成果得到保护,并为社会和工业效益提供杠杆。许多硕士和博士毕业生在电子通信研究院(ETRI)和韩国科学技术研究院(KIST)等顶尖研究机构就业,或成为延世大学等机构的教授。其他毕业生继续在技术开发领域的领先公司工作。 金教授表示:“目前显示技术研究进展面临的最大挑战是显示产业本身的停滞不前。消费者更换电视和智能手机的频率降低了,而高端电视的高成本让许多人不敢升级。虽然性能在不断进步,但缺乏可负担性限制了更广泛的采用。此外,AR和VR等显示技术的新市场在技术上仍不成熟。在这些技术得到广泛采用之前,需要解决显示质量、延迟和用户舒适度等问题。这些因素共同构成了推动创新和扩大行业的挑战。”对于显示技术的哪些新兴领域最有前景,Kim认为,基于微led和量子点(QD)的显示正在塑造视觉显示的未来。他预计OLED将在至少10年内主导高端显示行业,因为微led和发光量子点技术在成为主流之前仍面临重大挑战。金教授表示:“目前,OLED技术在平板电脑和智能手机等信息技术(IT)设备上得到了广泛的应用,它具有轻薄、高画质、高能效的设计。在AR/VR中,6,000 ppi或更高的超高像素密度和高达10,000尼特的亮度水平对于身临其境和逼真的视觉效果至关重要,即使在紧凑型设备中也是如此。这些进步依赖于改进的发射材料和精确的像素结构来平衡分辨率、功率效率和亮度。“除了IT和AR/VR, OLED和微led正在彻底改变大型显示器,提供卓越的能源效率,出色的对比度和增强的色彩准确性。可模式化发射材料的创新继续解决制造和性能稳定性方面的挑战。”在研究时间之外,Kim强调充分休息的重要性,以补充精神和身体的能量储备。“虽然努力工作和保持专注很重要,但我相信休息和给自己留点时间对提神醒脑同样重要。我注意到,当我不间断地把自己逼得太紧时,我的激情和动力就会逐渐消退。“我经常在空闲时间参观艺术画廊。我特别喜欢那些创造性地重新诠释主题的作品,因为它们经常为我的研究提供意想不到的灵感。创造力是科学和工程创新的重要因素,突破往往源于探索新材料或设计其他人可能没有考虑到的新结构。虽然艺术和科学是根本不同的学科,但观察提供新鲜视角的艺术有时可以为我的工作激发独特和创新的想法。“我也鼓励我的学生花时间充电。我们的实验室组织了夏季和冬季的务虚会,在那里我们参加体育活动和其他活动来放松和缓解压力。”金教授认为,延世大学可以通过优先进行尖端研究,继续吸引优秀人才,并推进显示技术。此外,与全球显示领域的行业领导者保持甚至加强合作关系将为学生提供宝贵的机会。“在过去20年的教学生涯中,我有幸指导了大约50名毕业生。听到他们在工业界和学术界的成就,我充满了巨大的喜悦和使命感。知道我在塑造他们的旅程中扮演了一个小小的角色,这是我职业生涯中非常令人欣慰的一部分。”金教授认为,通过提供有竞争力的奖学金、保持先进的设施、培养跨学科教育,不仅可以吸引国内人才,还可以吸引世界各地的人才。此外,专注于可持续显示技术,如低功耗显示和可回收材料,将与全球趋势保持一致,并吸引创新、影响驱动的候选人。这些战略将巩固延世在显示技术研究和教育方面的领导地位。”
