Patent number: 12170057Abstract: A light-emitting circuit includes a first transistor, a second transistor, a light-emitting element, a first switching circuit, a second switching circuit, a first capacitor, a current source, and a third switching circuit. The first switching circuit, the second switching circuit, and the third switching circuit are synchronously turned on or synchronously turned off. This not only controls the current flowing through the first switching circuit through the first capacitor, the second switching circuit and the current source to the third power line, and but also controls the current flowing through the third switching circuit, the second transistor through the first capacitor, the second switching circuit and the current source flow to the third power line. Since the current passes through the first transistor and the second transistor, the current flowing through the light-emitting element is reduced, improving adverse effects of parasitic capacitance and wire resistance to the two transistors.Type: GrantFiled: December 17, 2023Date of Patent: December 17, 2024Assignee: Shenzhen China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Yamei Bai, Tianhong Wang

Publication number: 20230154427Abstract: The present invention discloses an array substrate and a display device. The present invention employs a flip pixel framework of a DD+G wiring method, and a design of disposing a GOA circuit on a source electrode driver side. Because two of the data lines adjacently and parallelly enter an AA region, the gate electrode fanout wire and the two data lines are not adjacent to each other but parallelly extend in AA region, which prevents coupling between the gate electrode fanout wire and the data lines signal. The method of using the width of two pixel units to perform a layout of a GOA circuit of one level further facilitates achievement of the narrow border.Type: ApplicationFiled: August 4, 2020Publication date: May 18, 2023Applicant: TCL China Star Optoelectronics Technology Co., Ltd.Inventors: Tianhong WANG, Yunxiao ZHONG, Ilgon KIM
