Patent number: 7951965Abstract: The present invention discloses a phenanthrene derivative having the following structure: wherein Ar1 and Ar2 independently are phenyl, nathphyl, heterocyclic group, polycyclic aromatic or polycyclic heterocyclic group with at least one conjugated substituent. The conjugated substituent can be an electron withdrawing group or electron donating group. The phenanthrene derivatives have semiconductor properties of electron transfer, electroluminescence (EL), and photoluminescence (PL). Intermolecular stacking can be avoided and electron-luminescent emission stability is enhanced when the derivatives are applied as a light-emitting material in organic EL devices due to the presence of the two stereo cyclopentane rings, such as a host compound or a dopant emitting blue light.Type: GrantFiled: February 4, 2005Date of Patent: May 31, 2011Assignee: Industrial Technology Research InstituteInventors: Chi Shen Tuan, Zong-Wei Tsai, Ching-Ian Chao, Shyue-Ming Jang, Chia-Kuo Yen

Patent number: 7285912Abstract: An organic electroluminescence device with a low reflectivity includes organic electroluminescence layers, a transparent electrode, a thin metal electrode, a control layer, and an auxiliary electrode. The transparent electrode and the thin metal electrode are sited on both sides of the OEL layer, respectively, in order to excite it to emit light. The auxiliary electrode and the thin metal electrode are mostly separated by a control layer. Both the auxiliary electrode and the thin metal electrode are locally connected to maintain electrically connected. Therefore, the control layer is not necessarily conductive and its material selection is not restricted by the requirement of work function matching with adjacent layers. The disclosed OLED device with a low reflectivity does not require a circular polarizer. It can be used for both active-matrix and passive-matrix OLED displays. The reflection of ambient light can be largely reduced to increase the contrast of the display panel.Type: GrantFiled: August 17, 2004Date of Patent: October 23, 2007Assignees: Industrial Technology Research Institute, WorldLED Co., LtdInventors: Ching Ian Chao, Chia Kuo Yen, En-Chung Chang
