The CF structure includes a nanostructure layer including multiple nanostructures and a light guide structure layer including multiple light guide structures, sequentially provided on the base. Each light guide structure is in a corresponding pixel region, and includes multiple light guide sub-portions. Each light guide sub-portion is in a corresponding sub-pixel region. Each sub-pixel region corresponds to a nanostructure, and each nanostructure is in a corresponding sub-pixel region. Each of the light guide sub-portions in one pixel region is configured such that light incident on the light guide sub-portions exits at different angles and enters into the nanostructure in the sub-pixel region corresponding thereto. Each nanostructure is configured such that light exiting from the sub-pixel region corresponding thereto has a predetermined color.Type: ApplicationFiled: May 20, 2020Publication date: January 20, 2022Inventors: Chengpeng YAO, Lei GUO, Zhendong LI, Wei ZHANG, Xia SHI, Jiaqing LIU

Patent number: 10866613Abstract: Disclosed are a conductive particle, an anisotropic conductive film, a display device, and a method for fabricating the same so as to detect the extent to which the conductive particles are cracked in a heating and pressurizing process, to thereby improve the ratio of finished products while the display device is being manufactured. A core of the conductive particle is a fluorescent resin core. In the conductive particle according to this disclosure, the core of the conductive particle is a fluorescent resin core, and the extent to which the conductive particle is cracked can be detected by detecting varying fluorescence in a heating and pressuring process, to thereby alleviate such a phenomenon from taking place that the conductive particle has a poor electrical conductivity due to an insufficient pressure, or the conductive particle is cracked, and thus loses its electrical conductivity, due to an excessive pressure.Type: GrantFiled: August 18, 2017Date of Patent: December 15, 2020Assignees: BOE Technology Group Co., Ltd., Hefei Xinsheng Optoelectronics Technology Co., Ltd.Inventors: Huan Ni, Fengzhen Lv, Xinxia Zhang, Xiao Guo, Qun Li, Xiaolong Xie, Chengpeng Yao, Mingguang Li

Patent number: 10712604Abstract: The present invention provides a display panel and a method for manufacturing the same. The method comprises steps of forming a black matrix and forming a sealant, wherein the black matrix layer contains a thermochromic material at the position corresponding to the sealant, so that when the sealant is cured with ultraviolet light, the thermochromic material layer is transparent. In such case, a side of the first substrate away from the sealant can be irradiated and ultraviolet light passes through the first substrate and the thermochromic material to cure the sealant, thus achieving a uniform irradiation of ultraviolet light and a high curing efficiency. After the sealant is cured, the thermochromic material can become black by changing the temperature thereof so as to avoid the light leakage.Type: GrantFiled: October 31, 2017Date of Patent: July 14, 2020Assignees: BOE TECHNOLOGY GROUP CO., LTD., HEFEI XINSHENG OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Huan Ni, Fengzhen Lv, Xinxia Zhang, Chengpeng Yao, Xiao Guo, Xiaolong Xie, Qun Li, Kui Lv
