Patent number: 9070891Abstract: A white color light source of an organic light emitting diode is provided and is suitable for irradiating on plants. The white color light source includes a first color light and a second color light. A peak in the frequency spectrum of the first color light is within a first wavelength range. A peak in the frequency spectrum of the second color light is within a second wavelength range. The white color light source is at least formed by mixing the first color light and the second color light, wherein an intensity of a frequency spectrum of a wavelength range from 520 nm to 580 nm is substantially equal to or less than 20% of a total intensity of a frequency spectrum of the white color light source.Type: GrantFiled: May 22, 2012Date of Patent: June 30, 2015Assignee: Au Optronics CorporationInventors: Ting-Yi Cho, Po-Hsuan Chiang, Wen-Huei Chen

Publication number: 20130342503Abstract: A signal enhancing method for capacitive touch panel of mobile device provides a reference potential by a reference bar that is next to a sensor bar, wherein when the reference potential is a ground potential, the reference bar becomes a ground (GND) bar. The sensor bar and GND bar may comprise a plurality of tiny sensor bars and a plurality of tiny GND bars, respectively; and may further comprise fishbone sensor bars and fishbone GND bars. The plurality of tiny sensor bars and plurality of tiny GND bars are arranged in an alternative disposition. In this way, when a touch panel is touched, a tiny sensor bar and adjacent tiny GND bar are both touched so as to obtain a large coupling capacitance.Type: ApplicationFiled: June 19, 2013Publication date: December 26, 2013Inventors: Chun Yu CHEN, Chang Kuang CHUNG, Ming Hui HUNG, Po Hsuan CHIANG

Publication number: 20130240849Abstract: An organic electroluminescent apparatus is provided. A first electrode layer is disposed above a substrate. A first color luminescent layer is disposed above the first electrode layer. A second color luminescent layer is disposed above the first color luminescent layer. A third color luminescent layer is disposed on the second color luminescent layer. A first color light emitted from the first color luminescent layer, a second color light emitted from the second color luminescent layer and a third color light emitted from the third color luminescent layer are mixed to form a white light. A first fluorescent layer is disposed on the substrate. The first fluorescent layer is excited by the first color light so as to emit the second color light, the third color light or a fourth color light.Type: ApplicationFiled: March 4, 2013Publication date: September 19, 2013Applicant: Au Optronics CorporationInventors: Po-Hsuan Chiang, Chung-Chia Chen, Chun-Liang Lin

Patent number: 8476624Abstract: In one aspect of the invention, an organic light emitting diode device has a substrate, a cathode formed on the substrate, an anode spaced-apart from the cathode, a plurality of electroluminescent units stacked between the cathode and the anode, and a plurality of charge generation layers, each of which is formed between two adjacent electroluminescent units. Each electroluminescent unit has an electron-transport layer, an emission layer formed on the electron-transport layer, and a hole-transport layer formed on the emission layer. The electron-transport layer of the first electroluminescent unit is formed on the cathode, defining a first energy barrier, and the anode is formed on the hole-transport layer of the last electroluminescent unit, defining a second energy barrier. The first energy barrier is higher than the second energy barrier. The first electroluminescent unit has a lifetime longer than that of each of the rest electroluminescent units.Type: GrantFiled: June 1, 2012Date of Patent: July 2, 2013Assignee: Au Optronics CorporationInventors: Chang-Yen Wu, Ting-Yi Cho, Meng-Ting Lee, Meng-Huan Ho, Po-Hsuan Chiang, Chieh-Wei Chen

Publication number: 20130146908Abstract: An illumination device including a substrate, a first conductive layer, a second conductive layer, a self-illuminating layer, and a first auxiliary conductive pattern layer is provided. The first conductive layer and the second conductive layer are disposed on the substrate. The self-illuminating layer is located between the first conductive layer and the second conductive layer to define an illumination region on the substrate. The first auxiliary conductive pattern layer is in contact with the first conductive layer and has an impedance smaller than that of the first conductive layer. A ratio of a perimeter (um) of the first auxiliary conductive pattern layer occupied in the illumination region to an area (um2) of the illumination region is greater than about 0 and smaller than or equal to about 0.0262 (1/um).Type: ApplicationFiled: February 9, 2012Publication date: June 13, 2013Applicant: AU OPTRONICS CORPORATIONInventors: Chen-Chi Lin, Po-Hsuan Chiang, Chang-Yen Wu, Chun-Liang Lin
