Patent number: 11881171Abstract: An electronic device including a substrate and a pixel circuit is provided. The substrate includes an active area and a peripheral area. The peripheral area is adjacent to the active area. The pixel circuit is disposed in the active area on the substrate. The pixel circuit includes an amplifier circuit and a tunable element. The amplifier circuit includes a non-inverting input terminal, an inverting input terminal, and an output terminal. The output terminal is electrically connected to the inverting input terminal, so that the amplifier circuit is a negative feedback circuit. The tunable element is electrically connected to the output terminal of the amplifier circuit.Type: GrantFiled: November 9, 2022Date of Patent: January 23, 2024Assignee: Innolux CorporationInventors: Ming-Chun Tseng, Kung-Chen Kuo, Lien-Hsiang Chen, Yong-Zhi Liu, Po-Syun Chen
