Patent number: 7286217Abstract: A power driven coaxial-rotating fast-orientation system and method is disclosed herein. The system includes a shiftable plate, an X-Y-axis driving device, a coaxial-rotating device, a coordinate indicator and a fixed microscope. The driving device moves the shiftable plate in X and/or Y-axis direction. The coaxial-rotating device load the display panel and enabling a coordinate alignment process performed thereto. The coordinate indicator is used to show the coordinate of the observed cell even if the panel is moving, so the object TFT cell can be located with reference to the value on the coordinate indicator. The cross mark from the view provided by the microscope can be used as a reference coordinate when adjusting the position of the display panel, and also available when searching intersection of the gate-lines and signal-lines with the corresponding numbers relating to the defective object cell on the display panel.Type: GrantFiled: May 3, 2004Date of Patent: October 23, 2007Assignee: AU Optronics Corp.Inventor: Chiao-Chung Huang

Publication number: 20070057934Abstract: A voltage converter includes a pulse width modulation circuit and a feedback circuit. The pulse width modulation circuit provides output voltages in the form of pulses and changes the value and frequency of the output voltages by changing the width, frequency and distribution of the pulses. The feedback circuit includes a resistor string formed by a plurality of resistors. One end of the resistor string is coupled to a variable voltage source. An input end of the pulse width modulation circuit is coupled to two adjacent resistors of the resistor string. The voltage converter adjusts the output voltages by adjusting the variable voltage sources.Type: ApplicationFiled: December 1, 2005Publication date: March 15, 2007Inventors: Xuan-Ce Jia, Chiao-Chung Huang, Xin-Lu Yang

Publication number: 20060169110Abstract: An apparatus for splitting a test piece. The apparatus includes a base, two pillars and a sliding piece. The base has a centerline. The pillars are disposed on the base. The connection line between the pillars is perpendicular to and divided equally by the centerline. The sliding piece disposed on the base has two fingers parallel to the centerline, and the connection line between the tips of the fingers is perpendicular to and divided equally by the centerline. When splitting a test piece, the sliding piece is pushed to split the test piece along the slits by the fingers and the pillars.Type: ApplicationFiled: September 18, 2003Publication date: August 3, 2006Inventors: Chiao-Chung Huang, Kuo-Kang Yeh, Ming-Hann Tsai, Po-Tsun Chen, Kuo-Ming Huang

Publication number: 20040241329Abstract: A method for rubbing alignment films and an apparatus for processing the same are introduced. The method includes a step of providing a glass substrate coated by an alignment film and further having a visible region and an invisible region, a step of moving the glass substrate along a predetermined direction, and a step of rubbing the alignment film by an inversed roller with cloth on a surface thereof along an in-stream direction the same as the predetermined direction while the glass substrate is moving. By reverse rolling upon the alignment film, chips rubbed off the alignment film can be made not to hard contact with the alignment film on the visible region which has been rubbed by the cloth.Type: ApplicationFiled: January 22, 2004Publication date: December 2, 2004Applicant: AU Optronics Corp.Inventor: Chiao Chung Huang

Patent number: 6800409Abstract: A method and system of TMAH concentration adjustment. Absorption values A1, Y1 to Ym of a recycled developer solution at wavelength 210 nm and m wavelengths between 220 nm and 250 nm are measured respectively, wherein m is equal to or greater than 2. Y1 to Ym are input to an nth-degree polynomial to generate a wavelength-absorption relationship Y=C1Xn+ . . . +Cn−1X+Cn, wherein X is wavelength, n is a positive integer and C1 to Cn are coefficients of the relationship. Wavelength 210 nm is input into the wavelength-absorption relationship to generate an absorption value Y210. A difference A3 between the A1 and Y210 is calculated as the absorption value of TMAH in the developer solution and A3 is then input to an absorption calibration curve of TMAH at 210 nm to generate a corresponding TMAH concentration. TMAH is then added to provide the corresponding TMAH concentration.Type: GrantFiled: September 24, 2003Date of Patent: October 5, 2004Assignee: AU Optronic Corp.Inventor: Chiao-Chung Huang
