Publication number: 20240120344Abstract: Embodiments of the present disclosure are directed to a display panel and a display device. A width of the fan-out wire positioned at the outer side is increased such that the impedance of the outer fan-out wire could be reduced. Furthermore, the second part of the second fan-out wire is bended in a direction away from the display region. This means that the second part only occupies the right/left redundant space and thus the second fan-out wire consumes less space of the lower side frame and the width of the fan-out region decreases. The present disclosure could achieve both comparatively low impedance of the fan-out wire and a narrow side frame.Type: ApplicationFiled: March 14, 2022Publication date: April 11, 2024Applicant: WUHAN CHINA STAR OPTOELECTRONICS TECHNOLOGY CO., LTD.Inventors: Zuoyuan Xu, Nian Hu

Publication number: 20210225598Abstract: The present invention discloses a muted key module, an electronic device and an implementation method. The key module includes a switch member, a triggering mechanism and a supporting member, wherein the triggering mechanism is arranged corresponding to the switch member. The triggering mechanism can be moved along the contacting and separating directions of the switch member, thus to realize an ON or OFF operation of the switch member. A muting layer is arranged between the switch member and the supporting member. In the present invention, the muting layer is arranged between the switch member and the supporting member, so the impact force the between the triggering mechanism and the switch member can be cushioned by the muting layer, thereby reducing the noise produced when the key is pressed, thus to improve the quality of the final product as a whole.Type: ApplicationFiled: August 7, 2018Publication date: July 22, 2021Inventors: MING LI, CHUANCHUN CAO, NIAN HU, JlNXlN DING, QIDONG LI

Patent number: 7985594Abstract: The present invention provides methods for performing dynamic nuclear polarization using biradicals with a structure of formula (I) as described herein. In general, the methods involve (a) providing a frozen sample in a magnetic field, wherein the frozen sample includes a biradical of formula (I) and an analyte with at least one spin half nucleus; (b) polarizing the at least one spin half nucleus of the analyte by irradiating the frozen sample with radiation having a frequency that excites electron spin transitions in the biradical; (c) optionally melting the sample to produce a molten sample; and (d) detecting nuclear spin transitions in the at least one spin half nucleus of the analyte in the frozen or molten sample. The present invention also provides biradicals with a structure of formula (I) with the proviso that Q1 and Q2 are different when X1 and X2 are —O—. The present invention also provides methods for making biradicals with a structure of formula (IA) as described herein.Type: GrantFiled: May 10, 2007Date of Patent: July 26, 2011Assignee: Massachusetts Institute of TechnologyInventors: Robert G.
