Patent number: 11978417Abstract: A pixel array substrate includes multiple data lines, multiple scan lines and multiple pixel structures. The scan lines include an m-th scan line and an (m+1)-th scan line arranged in sequence, and m is a positive integer. The pixel structures include first to twenty-fourth pixel structures. A control terminal of a transistor of the seventh pixel structure and a control terminal of a transistor of the eighth pixel structure are electrically connected to the (m+1)-th scan line and the m-th scan line respectively. A control terminal of a transistor of the thirteenth pixel structure and a control terminal of a transistor of the fourteenth pixel structure are electrically connected to the (m+1)-th scan line and the m-th scan line respectively.Type: GrantFiled: June 26, 2023Date of Patent: May 7, 2024Assignee: AUO CorporationInventors: Shiuan-Hua Huang, Lin-Chieh Wei, Chun-Min Wang

Patent number: 10775672Abstract: A display device includes a first substrate, first signal lines, second signal lines, active elements, pixel electrodes, a second substrate, a black matrix, a first spacer, and a second spacer. The active elements are electrically connected with the first signal lines and the second signal lines. The black matrix includes first portions and second portions. The first portions overlap the first signal lines. The second portions overlap the second signal lines. The first spacer overlaps a source and a drain of one of the active elements. The second spacer overlaps a source and a drain of another one of the active elements. The shortest distance between the center of the first spacer and the center line of the closest one of the first portions is different from the shortest distance between the center of the second spacer and the center line of the closest one of the first portions.Type: GrantFiled: October 8, 2019Date of Patent: September 15, 2020Assignee: Au Optronics CorporationInventors: Wei-Ren Chen, Lin-Chieh Wei

Patent number: 10388244Abstract: A display panel includes multiple gate lines and a gate driver. The gate driver includes multiple shift registers. Each of the shift registers includes a pull-up circuit, a driving circuit, and a pull-down circuit. The pull-up circuit charges a first node in the shift register. The driving circuit is coupled to the first node, and outputs, according to a voltage signal of the first node, a driving pulse signal to a corresponding gate line. The pull-down circuit is coupled to the driving circuit, and discharges one of the gate lines according to the voltage signal of the first node. The shift register includes a first shift register provided on a first side and a second shift register provided on a second side. The pull-down circuit in the first shift register discharges a gate line corresponding to the second shift register according to the voltage signal of the first node.Type: GrantFiled: February 23, 2018Date of Patent: August 20, 2019Assignee: AU OPTRONICS CORPORATIONInventors: Chun-Min Wang, Lin-Chieh Wei
