Patent number: 11960160Abstract: A spliced screen and a display terminal are disclosed. In the spliced screen, a structural component is disposed on two adjacent display panels and covers a splicing gap between the two adjacent display panels. A lamp plate is disposed on a surface of the structural component. When the spliced screen displays an image, a plurality of luminescent bodies disposed on the lamp plate close to the display panels also emit light, thereby preventing black strips from appearing on the image. In the spliced screen, a viewing angle of the display panels and a viewing angle of the lamp plate are same, so that a brightness of the display panels and a brightness of the lamp plates are same when the spliced screen is viewed from a lateral side. As such, display quality is improved.Type: GrantFiled: December 21, 2021Date of Patent: April 16, 2024Assignee: TCL China Star Optoelectronics Technology Co., ltd.Inventors: Jun Zhao, Bin Zhao, Juncheng Xiao, Hongyuan Xu, Huajun Lu

Publication number: 20240113082Abstract: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A light absorbing layer is arranged in the first gap between at least two adjacent light emitting elements. By arranging the light absorbing layer, the side light of the light emitting elements can be partially absorbed, thereby reducing an emission angle of the light bar.Type: ApplicationFiled: December 22, 2021Publication date: April 4, 2024Applicants: HUIZHOU CHINA STAR OPTOELECTRONICS DISPLAY CO., LTD., TCL CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Huajun LU, Juncheng XIAO, Hongyuan XU

Publication number: 20070147738Abstract: A fiber-optic sensor includes a Fabry-Perot cavity, the length of which may be altered by deposition of a material of interest that may be deposited or captured on an end surface thereof. The sensor may also be tapered near the end surface to a tip diameter in the range of a few micrometers or a few micrometers by a variety of techniques which may be used singly or in combination. A tapered probe of such dimensions is of minimal intrusiveness in biological observations and can be used to probe sub-micron sized cells in vivo. By developing a multi-layer self-assembled film to immobilize a capture material such as a DNA sequence complementary to a DNA sequence of interest or other organic material such as proteins, antigens and/or antibodies materials of interest may be preferentially captured and immediately detected by alteration of spectral response of the fiber-optic sensor.Type: ApplicationFiled: December 12, 2006Publication date: June 28, 2007Inventors: Xingwei Wang, Juncheng Xu, Zhuang Wang, Anbo Wang

Patent number: 7173713Abstract: A diaphragm optic sensor comprises a ferrule including a bore having an optical fiber disposed therein and a diaphragm attached to the ferrule, the diaphragm being spaced apart from the ferrule to form a Fabry-Perot cavity. The cavity is formed by creating a pit in the ferrule or in the diaphragm. The components of the sensor are preferably welded together, preferably by laser welding. In some embodiments, the entire ferrule is bonded to the fiber along the entire length of the fiber within the ferrule; in other embodiments, only a portion of the ferrule is welded to the fiber. A partial vacuum is preferably formed in the pit. A small piece of optical fiber with a coefficient of thermal expansion chosen to compensate for mismatches between the main fiber and ferrule may be spliced to the end of the fiber.Type: GrantFiled: March 4, 2004Date of Patent: February 6, 2007Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Juncheng Xu, Anbo Wang

Patent number: 7054011Abstract: A fiber optic sensor has a hollow tube bonded to the endface of an optical fiber, and a diaphragm bonded to the hollow tube. The fiber endface and diaphragm comprise an etalon cavity. The length of the etalon cavity changes when applied pressure or acceleration flexes the diaphragm. The entire structure can be made of fused silica. The fiber, tube, and diaphragm can be bonded with a fusion splice. The present sensor is particularly well suited for measuring pressure or acceleration in high temperature, high pressure and corrosive environments (e.g., oil well downholes and jet engines). The present sensors are also suitable for use in biological and medical applications.Type: GrantFiled: August 5, 2004Date of Patent: May 30, 2006Assignee: Virginia Tech Intellectual Properties, Inc.Inventors: Yizheng Zhu, Xingwei Wang, Juncheng Xu, Anbo Wang
