Patent number: 11887529Abstract: A pixel array is provided. The pixel array includes a plurality of pixels, wherein each of the pixels includes a light emitting diode, a first transistor, a second transistor, a third transistor, a fourth transistor, and a fifth transistor. The first transistor receives a first data signal and a first scan signal. The second transistor is coupled to the first transistor and an anode of the light emitting diode. The third transistor receives a system high voltage and a first control signal, and is coupled to the second transistor. The fourth transistor is coupled to an anode of a light emitting diode of an adjacent pixel, a control terminal of the third transistor, and a cathode of the light emitting diode. The fifth transistor is coupled to the cathode of the light emitting diode, and receives a second control signal and a system low voltage.Type: GrantFiled: April 19, 2022Date of Patent: January 30, 2024Assignee: Au Optronics CorporationInventors: Ya-Jung Wang, Jing-Wun Jhang, Rong-Fu Lin, Nien-Chen Li, Hsien-Chun Wang, Che-Chia Chang, June Woo Lee, Hsin-Ying Lin, Chia-Ting Hsieh, Chien-Fu Huang, Sung-Yu Su

Patent number: 11011105Abstract: A pixel circuit includes a light-emitting device, a first transistor, a second transistor, a first capacitor, a third transistor, a fourth transistor, and a fifth transistor. The first transistor and the fourth transistor are controlled by a light-emitting signal. The third transistor and the fifth transistor are controlled by a scan signal. The light-emitting device, the first transistor, the second transistor, the fourth transistor, and the fifth transistor are serially connected between a system high voltage and a system low voltage. The third transistor is coupled between a data signal and a control terminal of the first transistor. The first capacitor is coupled between a control terminal and a downstream terminal of the second transistor. The fifth transistor is coupled between the downstream terminal of the second transistor and a charging reference voltage. A current of the charging reference voltage is less than a current of the system low voltage.Type: GrantFiled: March 24, 2020Date of Patent: May 18, 2021Assignee: Au Optronics CorporationInventors: Hsien-Chun Wang, Ya-Jung Wang, Jing-Wun Jhang, Chen-Feng Fan, Wan-Heng Chang, Sung-Yu Su
