Patent number: 11908395Abstract: An electronic device including a panel, a Chip on Film and a flexible circuit board is disclosed. The panel includes a first gate driver, a switch transistor and a driving transistor. An output terminal of the switch transistor is coupled to a control terminal of the driving transistor. The first gate driver is used for receiving an AC signal and a DC signal and outputting a control signal to a control terminal of the switch transistor. The Chip on Film is electrically connected to the panel and used for transmitting a data signal to an input terminal of the switch transistor and transmitting the AC signal to the first gate driver. The flexible circuit board is electrically connected to the panel and used for transmitting a power signal to an input terminal of the driving transistor and transmitting the DC signal to the first gate driver.Type: GrantFiled: February 8, 2023Date of Patent: February 20, 2024Assignee: InnoLux CorporationInventors: Chun-Hsien Lin, Jui-Feng Ko, Geng-Fu Chang

Patent number: 11527217Abstract: A display panel including a first current source and a first pixel unit is provided. The first pixel unit includes a first switch and a first light-emitting diode. The first switch is coupled to the first current source and receives a first scan signal. When the first scan signal is enabled, the first switch is turned on and receives a first current provided by the first current source. The first light-emitting diode is coupled to the first switch. When the first switch is turned on, the first current passes through the first light-emitting diode to turn on the first light-emitting diode.Type: GrantFiled: June 23, 2017Date of Patent: December 13, 2022Assignee: INNOLUX CORPORATIONInventors: Geng-Fu Chang, Tsau-Hua Hsieh, Jui-Feng Ko, Tung-Kai Liu, Hirofumi Watsuda
