Patent number: 10579186Abstract: A method and a detection circuit for selecting a touch detection time are provided. The method for selecting a touch detection time includes the following steps: detecting a noise signal of a touch panel in a first display frame period; determining whether signal strength of the noise signal in a first time segment in the first display frame period is greater than a first noise threshold; and when the signal strength of the noise signal in the first time segment in the first display frame period is less than the first noise threshold, performing touch control in a second time segment in a second display frame period corresponding to the first time segment.Type: GrantFiled: July 24, 2018Date of Patent: March 3, 2020Assignee: AU OPTRONICS CORPORATIONInventors: Szu-Che Yeh, Chi-Cheng Chen, Feng-Ming Hsu, Gui-Wen Liu

Patent number: 9558698Abstract: A driving method for driving a display apparatus including a plurality of pixels, a plurality of data lines and a data driver. The data driver includes a first latch outputting a first sample data signal to a second latch, the second latch, a first charge sharing line and a second charge sharing line. The method includes performing a first charge sharing when a polarity of one of the pixels changes so as to output a first calibrated data signal to the data line electrically coupled to the pixel, and executing a second charge sharing when the most significant bit of the first sample data signal is different from the most significant bit of the second sample data signal so as to output a second adjusted data signal to the data line.Type: GrantFiled: December 10, 2014Date of Patent: January 31, 2017Assignee: AU OPTRONICS CORP.Inventors: Wei-Jyun Chen, Chun-Fan Chung, Szu-Che Yeh

Publication number: 20110075043Abstract: In one aspect, the present invention relates to a method of processing images. In one embodiment, the method includes the steps of processing an image having a plurality of image pixels expressed in grey level values, GLIN(i), of n bits in a RGB color domain so as to obtain the maximum gray level value among the gray level values of all RGB colors of the plurality of image pixels, determining a color shift compensation coefficient, ?M, according to the maximum gray level value of the image, and transforming the image into an output image having grey level values, GLOUT(i), that satisfies the relationship of GLOUT(i)=?M×GLIN(i)?N.Type: ApplicationFiled: September 28, 2009Publication date: March 31, 2011Applicant: AU OptronicsInventors: Ming-Fon Chien, Hao-Chung Hsu, Szu-Che Yeh

Patent number: 7903073Abstract: A display is provided. The display includes a first timing controller, a second timing controller and drivers. The first timing controller receives and transmits a first portion of pixel values, in which the first portion of the pixel values includes the pixel values of at least two non-adjacent pixels. The second timing controller receives and transmits a second portion of the pixel values, in which the second portion of the pixel values includes the pixel values of at least two non-adjacent pixels. Each of the drivers receives respectively a part of the first portion of the pixel values transmitted by the first timing controller and a part of the second portion of the pixel values transmitted by the second timing controller. A method of transmitting image data in the display is also disclosed.Type: GrantFiled: November 29, 2007Date of Patent: March 8, 2011Assignee: Au Optronics CorporationInventors: Chun-Fan Chung, Sheng-Kai Hsu, Yung-Tse Cheng, Szu-Che Yeh, Li-Ru Lyu, Chih-Sung Wang
