target="_blank" class="relatedlink">显示</a>器学会研讨会当中，“信息显示学会(SID)”的研论会上已经不再设置有关CRT的发表，12月5日～7日召开的“IDW '07（第14届国际显示器技术专题讨论会）”上的发表将是有关CRT开发的最后一次国际性发表。 <br /> <br /> 在本届IDW的“CRTs专题”上共有4场会议，发表13篇论文。其中，山崎映一（咨询师，原日立制作所）以“Invited History of CRT Development”为题，回顾了“CRT”已过百年的发展史。CRT于1897年由德国布朗（K. F. Braun）发明，“Braun tube：布朗管”因此而得名。 <br /> <br /> 电视机的先驱是1926年由日本的高柳先生实现的“イ”字影像。50年代彩色CRT被发明出来并投入使用，CRT作为图像显示装置达到鼎盛阶段。21世纪进入数字电视和高清电视的时代，CRT被LCD及PDP等<a href="http://display.oecr.com" target="_blank" class="relatedlink">平板</a>显示器取代。但在图像方面平板显示器尚有需要改进之处。 <br /> <br /> 与讨论会会场设在一起的展示会场上，展出了对电视行业具有重要意义的“藤冈收藏品”（图1、图2）。CRT实物、世界首款彩电等，会场上还用50年代的黑白电视机播放了NHK的节目。 <br /> <br /> 图1的左下方有“Model 17-T2, Columbia 1955, 100V, 80W, 600W×500D×570H, 25kg”的说明。1955年（昭和30年）生产的黑白电视机现在还能工作。看上去很像“电影《三丁目的夕阳》中铃木家的电视机”。据说，世界遗产级别的大量“收藏品”今后将在静冈大学展出。（特约撰稿人：小穴 保久，LG飞利浦LCD日本研究所） <br /> <br /> <ignore_js_op> <img id="aimg_21428"
