Patent number: 11983052Abstract: A display device and a bezel thereof are provided. The display device includes a display panel and a bezel. The display panel has a first surface and a second surface. The first surface includes at least one pixel pad section, and the second surface includes at least one circuit pad section. The bezel includes a first surface connecting portion, a second surface connecting portion and at least one conductive wire. The edge of the display panel having the pixel pad section and the circuit pad section is accommodated between the first surface connecting portion and the second surface connecting portion. Each conductive wire has a first end and a second end. The first end is disposed on the first surface connecting portion and the second end is disposed on the second surface connecting portion. The part of the first connecting portion having the first end corresponds to the pixel pad section, and the part of the second connecting portion having the second end corresponds to the circuit pad section.Type: GrantFiled: May 28, 2021Date of Patent: May 14, 2024Assignee: AU OPTRONICS CORPORATIONInventors: Yi-Fan Chen, Che-Chia Chang, Shang-Jie Wu, Yu-Chieh Kuo, Yi-Jung Chen, Yu-Hsun Chiu, Mei-Yi Li, He-Yi Cheng

Patent number: 8749723Abstract: A driving method for a panel structure including at least two liquid crystal layers is disclosed. The liquid crystal layers display different colors. When the panel structure includes a first liquid crystal layer and a second liquid crystal layer, the first and the second liquid crystal layers are initialized. A light source is utilized to emit the first and the second liquid crystal layers to write data to at least one of the first and the second liquid crystal layers. When the panel structure further includes a third liquid crystal layer, the first, the second and the third liquid crystal layers are first initialized. A light source is utilized to emit the first, the second and the third liquid crystal layers to write data to at least one of the first, the second and the third liquid crystal layers.Type: GrantFiled: January 29, 2010Date of Patent: June 10, 2014Assignee: Industrial Technology Research InstituteInventors: Shang-Chia Chen, Heng-Yin Chen, Chao-Chiun Liang
