Patent number: 8803833Abstract: A touch panel includes a display module, a touch sensor and a signal processing unit. The display module includes a timing control circuit and a data driving circuit, wherein the timing control circuit outputs latch signals to the data driving circuit, and the display module generates surface noises. The touch sensor is disposed above the display module and outputs abnormal signals, wherein the abnormal signals include a sensing signal and the surface noises. The signal processing unit is electrically connected to the touch sensor and receives the abnormal signals, wherein the signal processing unit calculates a predetermined time by utilizing a rising edge or a falling edge of the latch signal, suspensively processes the sensing signal during the predetermined time, and then continuously processes the sensing signals beyond the predetermined times so as to keep away from each period of the surface noises.Type: GrantFiled: June 22, 2012Date of Patent: August 12, 2014Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Chien-Lin Yeh, Chun-Cheng Hou

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
