Patent number: 8648337Abstract: A stratified organic light-emitting diode structure includes a thin-film transistor and an organic light-emitting diode (OLED). The OLED is fabricated on a planarization layer that has a top surface substantially parallel to the substrate, and the layers in the organic light-emitting diode (OLED) are substantially parallel to each other. The major part of each OLED layer has a uniform thickness so that the OLED produces a uniform brightness. The planarization layer covers the thin-film transistor entirely and the planarization layer on top of the thin-film transistor is also covered by an insulation layer. In order to electrically connect the top electrode of the OLED to the drain terminal of the thin-film transistor, an opening is made through both the top insulating layer and the planarization layer to expose part of the drain terminal. Spacers with uniform height are fabricated on the top insulating layer to protect the pixel structure.Type: GrantFiled: April 3, 2012Date of Patent: February 11, 2014Assignee: AU Optronics CorporationInventor: Hsing-Hung Hsieh

Patent number: 6905977Abstract: The present invention discloses a method of improving an electroluminescent efficiency of a MOS device by etching a semiconductor substrate thereof. A chemical etching process is performed to remove surface states or surface defects located on the surface of a silicon substrate before a nanoparticle layer and a conducting layer is formed on the silicon substrate, in order that the non-radiative electron-hole recombination centers located on the surface of silicon substrate is suppressed. Accordingly, the percentage of radiative electron-hole recombination is heightened and the electroluminescent efficiency of a MOS light emitting device is drastically enhanced. Advantageously, the chemical etching step is able to create a nanostructure on the surface of the silicon substrate to increase the probability of the collision of electron-hole pairs and phonons, and the electroluminescent efficiency of a MOS light emitting device is improved as well.Type: GrantFiled: March 26, 2003Date of Patent: June 14, 2005Assignee: National Taiwan UniversityInventors: Ching Fuh Lin, Wu Ping Huang, Hsing Hung Hsieh, Eih Zhe Liang
