Publication number: 20240184158Abstract: A display panel and an electronic device are provided. The display panel includes a first substrate and a second substrate disposed opposite to each other, and a sealant between the first substrate and the second substrate. The light-shielding layer is located on a side of the second substrate facing toward the first substrate, and grooves are defined at positions where the sealant is. The grooves penetrate the light-shielding layer to block a path of water vapor entering the display panel through the light-shielding layer, thereby easing a problem of the intrusion path of the water vapor in current liquid crystal display panels.Type: ApplicationFiled: July 29, 2022Publication date: June 6, 2024Applicant: TCL China Star Optoelectronics Technology Co., Ltd.Inventors: Yaoxin PAN, Tuo FENG, Jintao JIANG

Patent number: 10347203Abstract: Disclosed is a GOA drive circuit, including a plurality of GOA drive units. Each trigger unit in first K GOA drive units includes a first thin film transistor, which has a gate connected to a trigger clock corresponding to the trigger unit. The trigger clock is configured to turn off the trigger unit when a scan clock of an output unit corresponding to the trigger unit is at a high level.Type: GrantFiled: May 4, 2017Date of Patent: July 9, 2019Assignee: SHENZHEN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Tuo Feng, Xiangyang Xu

Patent number: 10290717Abstract: The thin film transistor (TFT) contains a gate electrode metallic layer above a substrate, a gate insulator layer covering the substrate and the gate electrode metallic layer, a first source electrode metallic layer and a first drain electrode metallic layer above the gate insulator layer and separated by a gap, an active layer above the first source and first drain electrode metallic layers filling the gap and forming a ditch in the active layer above the gap, and a second source electrode metallic layer and a second drain electrode metallic layer above the active layer at two lateral sides of the ditch, respectively. The second source/drain electrode metallic layer contacts the first source/drain electrode metallic layer. The TFT has lower parasitic capacitance and takes up less area. As such, when the TFT is applied to a LCD, the reduced space consumed by the TFT enhances pixel's aperture ratio.Type: GrantFiled: October 26, 2015Date of Patent: May 14, 2019Assignee: Shenzhen China Star Optoelectronics Technology Co., LtdInventor: Tuo Feng
