Our group has been working on the development of OLED materials for more than 20 years.  This flat panel is extremely thin and light, that achieves excellent color reproduction and a flexible shape, and is seen as a clear departure from both LCD and plasma display technologies.<br \/>\nHodogaya Chemical has developed Hole Transport Materials (HTM) and Electron Transport Materials (ETM) for OLED applications using our long experience in synthesis technologies, including ultrapure organic chemicals such as Organic Photo Conductor (Charge Transport Materials), as well as computer-based molecule design technology.  Other OLED materials such as Emitting Materials and Hole Injection Materials are under development.<br \/>\nOur unique OLED materials will help to extend the life and stability of OLED devices.  We are also working on the development of Capping layer materials(CPL) that achieves high and low refractive index by utilizing optical simulation technology.<br \/>\nAs a leading manufacturer of OLED materials, the Hodogaya Chemical group supplies materials to major panel manufacturers both in Japan and overseas.<\/p>\n<\/div>\n<div class=\"boxInner mb50\">\n<h2 class=\"mt40\">Applications<\/h2>\n<div class=\"flexbox_image\">\n<div class=\"prdct_bg-box01\">\n<div class=\"prdct_bg-img1\"><img class=\"prdct_photo1\" src=\"https:\/\/www.hodogaya.co.jp\/english\/wp\/wp-content\/themes\/hodogaya\/img\/products\/01_01_01.png\" ><\/div>\n<p class=\"prdct-cap\"><i class=\"fas fa-camera-retro\"><\/i>&ensp;Smart Phone<\/p>\n<\/div>\n<div class=\"prdct_bg-box02\">\n<div class=\"prdct_bg-img2\"><img class=\"prdct_photo1\" src=\"https:\/\/www.hodogaya.co.jp\/english\/wp\/wp-content\/themes\/hodogaya\/img\/products\/01_01_02.png\" ><\/div>\n<p class=\"prdct-cap\"><i class=\"fas fa-camera-retro\"><\/i>&ensp;OLED TV<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"boxInner mb50\">\n<h2 class=\"mt40\">Spotlight on Products and Technologies<\/h2>\n<p class=\"tit_6\">Basic Principles of OLED Technology<\/p>\n<p class=\"mb30\">\u2018EL\u2019 stands for electroluminescence, which is a light emitting system featuring organic compounds that emit light when electric current is applied.<br \/>\nAn OLED display is a laminated construction, which consists of three layers, namely a hole transport layer (HTL), an emitting layer (EML) and an electron transport layer (ETL).  The HTL transports holes (plus), the ETL transports electrons (minus), and the holes and electrons are brought into the EML, and combined to emit light.<\/p>\n<div class=\"prdct_bg-box03\">\n<p class=\"tit_6\">OLED System<\/p>\n<p><img class=\"prdct_photo1\" src=\"https:\/\/www.hodogaya.co.jp\/english\/wp\/wp-content\/themes\/hodogaya\/img\/products\/01_01_03_25.png\">\n<\/div>\n<\/div>\n<div class=\"boxInner mb50\">\n<p class=\"tit_6\">Core technologies and strengths of the Hodogaya Chemical Group<\/p>\n<p class=\"mb20\">Hodogaya Chemical manufactures mainly Hole Transport Materials (HTM) that are used in the hole transport layer.  HTM technology is based on Charge Transport Materials (CTM) which were developed for electrophotography and printers.<br \/>\nWe have the advantage of being able to provide distinctive OLED materials through the synergy between Hodogaya Chemical&#8217;s strengths in HTM and the Light Emitting Materials developed and manufactured by our Korean group company SFC.<br \/>\nWe are also developing Electron Transport Materials (ETM) used in electron transport layers, and Capping layer materials(CPL).  From dyestuffs to imaging materials, and from imaging materials to OLED materials, Hodogaya Chemical is charting its course along with the flow of the times.<\/p>\n<p class=\"notes\">*Charge Transport Materials (CTM): Materials for the Organic Photo Conductor (OPC) drums that are a key component of electrophotographic copiers and printers.<\/p>\n<p><\/p>\n<p class=\"prdct-cap\">Subsidiary: <a class=\"text-link icontxtlink\" href=\"http:\/\/www.sfc-dye.com\/\" target=\"_blank\" rel=\"noopener\">SFC CO.,LTD.<\/a>\u3000<br \/>\nHODOGAYA CHEMICAL KOREA CO.,LTD.<\/p>\n<\/div>\n<div class=\"boxInner mb50\">\n<h2 class=\"mt40 clear\">Products<\/h2>\n<ul class=\"prdct-ul\">\n<li><a class=\"prdct-url_trtk\" href=\"https:\/\/www.hodogaya.co.jp\/english\/seihin\/htm\/\">Hole Transport Materials (HTM)<span><i class=\"fas fa-external-link-square-alt\"><\/i><\/span><\/a><\/li>\n<li><a class=\"prdct-url_trtk\" href=\"https:\/\/www.hodogaya.co.jp\/english\/seihin\/etm\/\">Electron Transport Materials (ETM)<span><i class=\"fas fa-external-link-square-alt\"><\/i><\/span><\/a><\/li>\n<li><a class=\"prdct-url_trtk\" href=\"https:\/\/www.hodogaya.co.jp\/english\/seihin\/htm-for-wet-process\/\">Hole Transport Materials for wet-process<span><i class=\"fas fa-external-link-square-alt\"><\/i><\/span><\/a><\/li>\n<li><a class=\"prdct-url_trtk\" href=\"https:\/\/www.hodogaya.co.jp\/english\/seihin\/oled-materials-2\/\">Other (Hole Injection Materials, Emitter Hosts, Emitting Materials)<span><i class=\"fas fa-external-link-square-alt\"><\/i><\/span><\/a><\/li>\n<\/ul>\n<\/div>\n<div class=\"prdct-cntact_box\">\n<ul>\n<li class=\"prdct-cntact1\"><i class=\"fas fa-paper-plane\"><\/i>Life &#038; Electronics Materials Division<\/li>\n<li class=\"prdct-cntact2\"><a href=\"https:\/\/www.hodogaya.co.jp\/english\/eng_cntct\/\"><i class=\"far fa-envelope\"><\/i>CONTACT<\/a>\n<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>OLED Materials Imaging Material Advanced Device Materials The arrival of the OLED display era These days, OLED [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":36,"menu_order":4,"comment_status":"closed","ping_status":"closed","template":"page.php","meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/pages\/44"}],"collection":[{"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/comments?post=44"}],"version-history":[{"count":7,"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/pages\/44\/revisions"}],"predecessor-version":[{"id":4564,"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/pages\/44\/revisions\/4564"}],"up":[{"embeddable":true,"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/pages\/36"}],"wp:attachment":[{"href":"https:\/\/www.hodogaya.co.jp\/english\/wp-json\/wp\/v2\/media?parent=44"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
