Patent number: 8542224Abstract: A display clip system and a timing clip control method thereof are provided. The clip system is connected to a gate driver circuit, and includes a timing controller and a clip module. According to a system input signal and its frame rates, the timing controller generates an enable signal, a clip trigger signal, and a base working signal. The clip module adjusts the base working signal by using the enable signal and the clip trigger signal. Then, the base working signal carries a first clip voltage to output to the gate driver circuit. When the frame rate changes, the timing controller adjusts trigger points and trigger time lengths of the enable signal and the clip trigger signal, and the clip module adjusts the base working signal. Then, the base working signal carries a second clip voltage equal to the first clip voltage to output to the gate driver circuit.Type: GrantFiled: May 31, 2011Date of Patent: September 24, 2013Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chung-Chih Hsiao, Chiao-Lin Huang

Publication number: 20130057520Abstract: A display, a timing controller, and an operation method thereof are provided. The operation method includes following steps. A first row image data and a second row image data are received sequentially. A row display data and a horizontal clock signal are outputted according to the first row image data. The first row image data and the second row image data are compared. When the first row image data and the second row image data are equal, the output of the horizontal clock signal and the row display data generated based on the second row image data discontinues. When the first row image data and the second row image data are not equal, the horizontal clock signal and the row display data generated based on the second row image data are outputted.Type: ApplicationFiled: November 29, 2011Publication date: March 7, 2013Applicant: CHUNGHWA PICTURE TUBES, LTD.Inventors: Chung-Chih Hsiao, Chih-Jung Chien

Publication number: 20130038586Abstract: A liquid crystal display device including a liquid crystal panel, a gate driver unit, a source driver unit and a clock generator and a method thereof are disclosed to improve display quality. The liquid crystal panel comprises a pixel array for displaying images. The gate driver unit for generating plural driving signals drives the pixel array. The source driver unit for generating plural driving signals drives the data of the image signals. The clock generator electrically coupled to the gate driver unit generates clock signals to control an operation of the gate driver unit. A bright line is likely to occur in an image area since the last two gate driver output lines of the last two stages are not coupled to the liquid crystal panel. A solution with the duty cycle of a clock signal generated by the clock generator is adjusted to solve the aforementioned problem.Type: ApplicationFiled: November 18, 2011Publication date: February 14, 2013Applicant: Chunghwa Picture Tubes, LTD.Inventors: CHUNG-CHIH HSIAO, Chun-cheng Hou

Patent number: 8308935Abstract: The present invention relates to a bio-sensing device capable of automatically detecting a sensing code and a sensing method thereof. The bio-sensing device has a bio-sensing strip and a process-and-display unit. The bio-sensing strip has a passive component, wherein a physical value of the passive component is able to present a sensing code. When the bio-sensing strip is inserted into the process-and-display unit, the process-and-display unit reads the sensing code to produce an appropriate compensation value of a sample. Moreover, by the sensing method, the process-and-display unit is able to detect the sensing code of the bio-sensing strip, and automatically, to access, calculate, compensate, and display the sensing code of the sample.Type: GrantFiled: January 25, 2010Date of Patent: November 13, 2012Assignee: R3dstar Biomedical Corp.Inventors: Chun-Yu Chen, Chung-Chih Hsiao, Chung-Ping Tang

Patent number: 8269711Abstract: An LCD (Liquid Crystal Display) Device of improvement of flicker upon switching frame rate and method for the same are proposed. The LCD device includes a pixel matrix, a timing controller and a gate driver. The timing controller outputs a first Gate-On-Enable signal to the gate driver, when the LCD device displays frame according to a first frame rate. When the first frame rate is switched to a second frame rate, the timing controller outputs a second Gate-On-Enable signal to the gate driver to cause a charge time of the pixel matrix to be unchanged. It is appreciated that a pulse width of the second Gate-On-Enable signal is equal to a summation of a pulse width of the first Gate-On-Enable signal and an adjusted pulse width.Type: GrantFiled: October 12, 2009Date of Patent: September 18, 2012Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chung-Chih Hsiao, Jiao-Lin Huang, Ming-Xian Li
