The LED chips are disposed on and electrically connected to the carrier. An equivalent wavelength of the first light emitted from the LED chips and divided into groups is ?. A variation of peak wavelengths of the LED chips in one group is smaller than 5 nm. ? meets an equation: ? = ? 1 n ? ( ? ? ? i × Ni × Ki ) ? 1 n ? Ni × Ki n is an integer equal to or larger than 2. ?i, Ni, and Ki are respectively an average peak wavelength, an quantity, and an average output efficiency of the LED chips in one group. The variation of ?i in different groups is ??i. 5 nm???i?30 nm. The wavelength converting material is excited by the first light to emit a second light.

Patent number: 7061117Abstract: A bump layout on the active region of a driver IC for increasing overall bump count. The layout fits IC packages that have a narrow and long body profile. Bumps are positioned close to the long side and central regions of the active region so that low marking pressure on the shorter sides of the package during chip-glass bondage is avoided. Dummy bumps may also be positioned close to the shorter sides of the package so that pressure distribution is optimized during chip-glass bondage.Type: GrantFiled: March 18, 2004Date of Patent: June 13, 2006Assignee: Au Optronics CorporationInventors: Wen-Chih Yang, Feng-Cheng Su, Chin-Chen Yang

Patent number: 6590555Abstract: A LCD panel driving circuit, comprising a gate driver for outputting a scan signal, a data driver for outputting a video signal, a switch circuit, and a temperature sensor. The temperature sensor detects the operating temperature of the LCD panel to determine whether or not the detected temperature is over a switch temperature and produces a selection signal. The switch selects a 1-line dot inversion control signal or a 2-line dot inversion control signal according to the selection signal and outputs a polar control signal, thereby controlling the selection of the outputted video signal polarity.Type: GrantFiled: March 2, 2001Date of Patent: July 8, 2003Assignee: Au Optronics Corp.Inventors: Feng-Cheng Su, Chun-Chin Tseng
