Patent number: 10998069Abstract: An electronic device includes an active area and multiple shift registers. The active area comprises multiple pixel circuits. Each of the multiple shift registers is configured to output a first control signal, a second control signal, and a third control signal to a part of pixel circuits of the multiple pixel circuits. A duty ratio of the third control signal is greater than a duty ratio of the second control signal, and the duty ratio of the second control signal is greater than a duty ratio of the first control signal. A part of the multiple shift registers and other part of the multiple shift registers are substantially symmetrically disposed at two sides of the active area, respectively.Type: GrantFiled: February 14, 2020Date of Patent: May 4, 2021Assignee: AU OPTRONICS CORPORATIONInventors: Ling-Ying Chien, Kuang-Hsiang Liu, Chee-Wai Lau

Patent number: 9030399Abstract: A gate driver for driving a TFT-LCD panel includes a number of gate-driver circuits arranged in groups and stages. Each gate-driver circuit has a main driver and an output section. The main driver is used to provide a charging signal to the output section which has two or more output circuits. Each of the output circuits is configured to provide a gate-line signal in response to the charging signal and a clock signal. The gate-driver circuit uses fewer switching elements, such as thin-film transistors, than the conventional circuit. When the gate driver is integrated in a TFT-LCD display panel and disposed within the periphery area around the display area, it is desirable to reduce or minimize the number of switching elements in the gate driver so that the periphery area can be reduced.Type: GrantFiled: February 23, 2012Date of Patent: May 12, 2015Assignee: AU Optronics CorporationInventors: Chien-Chang Tseng, Kuang-Hsiang Liu, Sheng-Chao Liu, Che-Chia Chang, Ling-Ying Chien
