我国液晶面板产业迎来新机遇期 产量已位居全球第二

2017-05-24 16:08:07   经济参考报

欧阳钟灿说,超高清显示技术不仅仅应用在电视机产业,更将带动医疗显示、数字标牌、安防监控、车联网等行业的发展。预计到2020年,8K超高清影像产业将超过1万亿人民币。在医疗显示领域,日本从2014年便开展了8K内窥镜临床研究手术实验,利用比人眼成像分辨率更高的超高清技术对病灶进行精细显示。

据介绍,8K超高清显技术达到了人类肉眼分辨的极限,是新一代全球产业竞争的关键技术。京东方8K超高清显示屏研发团队负责人黄应龙说,京东方2012年底决定研发8K技术的时候,就对难度有了预判,但是创新研发过程之难还是超出想象。

“第一批显示屏做出来的时候,一块屏仅有十六分之一亮了,当时真的感到非常失落”。黄应龙说,“那段时间,工程师们每天工作15个小时以上,进行了300多个小时极为艰难的调试和改进,最后终于让整块屏都亮了起来!”

需防范产能过剩加速产业升级

据国际权威机构预测,2021年,全球液晶面板需求将达2.15亿平方米,而液晶面板供给将达2.45亿平方米,呈现产能过剩态势。

季可彬认为,未来面板的供需平衡和面板厂的产能利用率取决于有多少条新的高世代线会最终量产。如果有过多高世代线投建并量产,那么全球面板制造商的年产能利用率将可能进入不健康区段。

有关专家表示,当前应进一步强化对国内产业统筹规划,防范产能过剩风险,集中优质资源投入战略性技术、材料和产品的研发。

而液晶面板产业的过度投资也已引起了国家方面的关注,并提醒地方政府不要盲从。

在去年11月举行的2016国际显示产业高峰论坛上,工业和信息化部电子信息司处长王威伟指出了显示产业发展的弊端。他认为,显示产业的产业链配套能仍然很弱,70%的上游材料依赖进口。同时,产品还不能完全满足下游新兴应用的需求,比如VR对屏的分辨率要求很高,现在的产品距离应用还有一定的差距。此外,我们的产品附加值低且投资主体相对分散,产品同质化较为严重。

王威伟说,未来国家将会在政策上加以调整,重点支持新一代显示技术的研发。现在,显示产业要加速产业升级,从“提量”变成“提质”,同时在下游拓展新兴显示器的应用领域,而不是低水平的重复建设。
