Publication number: 20240127623Abstract: The present application discloses a display panel and a display device. The display panel includes a fingerprint recognition area. The display panel includes a cover plate and an optically transparent layer. The optically transparent layer at least covers a portion of the cover plate located in the fingerprint recognition area. A refractive index of the optically transparent layer is greater than a refractive index of air and less than a refractive index of a finger. A thickness of the optically transparent layer is an even multiple of a half-wavelength of a fingerprint recognition light ray. Half-wave loss and interference of light are used to improve fingerprint recognition performance.Type: ApplicationFiled: May 18, 2021Publication date: April 18, 2024Inventors: Chuan SHUAI, Guiyang ZHANG, Yaqiong LONG

Patent number: 8829659Abstract: An integrated circuit connection comprises a substrate, first and second transmission lines, a die, and a conductive ribbon. The first transmission line has a first end and is arranged on the substrate. The die is spaced from the first end. The die has a first surface, which is arranged on the substrate, and a second surface, which is opposite to the first surface and which has the second transmission line arranged thereon. The second transmission line has a second end. The conductive ribbon electrically couples the first and the second ends.Type: GrantFiled: August 4, 2010Date of Patent: September 9, 2014Assignee: Sony CorporationInventors: Xiaobing Sun, Yaqiong Zhang, Yugang Ma

Publication number: 20130104387Abstract: A method which relates to fabricating a dielectric waveguide (WG) on a PCB for RF communication between ICs on the PCB. The WG can replace a baseband copper bus and resulting in the PCB being smaller and/or cheaper. The WG may be printed, stamped, cut or prefabricated onto the PCB.Type: ApplicationFiled: August 17, 2012Publication date: May 2, 2013Applicant: Sony CorporationInventors: Yu Gang MA, Ching Biing Yeo, Hisashi Masuda, Yaqiong Zhang

Publication number: 20130049883Abstract: Conventional technologies using copper tracks to couple integrated circuits (ICs) disposed on printed circuit boards (PCBs) face limitations in scaling beyond a certain transmission rate, restricting their future applications. Described herein is a waveguide network, in which the network comprises ICs on a PCB coupled via a dielectric waveguide, which advantageously overcomes these limitations. The dielectric waveguide is able to transmit radio frequency (RF) signals and has a bandwidth of at least 100 GHz, among other features. Further, the network can be arranged with different topologies such as ring, star or bus based, and is also couplable to other equivalent networks on the PCB using suitable waveguide-based networking devices.Type: ApplicationFiled: August 17, 2012Publication date: February 28, 2013Applicant: Sony CorporationInventors: Yu Gang MA, Ching Biing Yeo, Hisashi Masuda, Yaqiong Zhang
