Publication number: 20240161968Abstract: A planar transformer is configured on a multi-layer circuit board of a resonant converter. The planar transformer includes multiple layers of primary-side traces, multiple layers of secondary-side traces, and an iron core. The primary-side traces serve as a primary-side coil of the transformer to generate a first direction magnetic flux when the resonant converter operates. The secondary-side traces serve as a secondary-side coil of the transformer to generate a second direction magnetic flux when the resonant converter operates. The primary-side traces and the secondary-side traces surround a first core pillar and the second core pillar, and the primary-side traces and the secondary-side traces are configured in a specific stacked structure on the multi-layer circuit board, so that a magnetomotive force of the planar transformer can maintain balance during the operation of the resonant converter.Type: ApplicationFiled: November 13, 2023Publication date: May 16, 2024Inventors: Yi-Hsun CHIU, Yi-Sheng CHANG, Chun-Yu YANG, Meng-Chi TSAI

Patent number: 10104335Abstract: A device applied to a display includes a receiving circuit, a detecting circuit, an image processing circuit and a response time enhancing circuit. The receiving circuit receives an input image signal. The detecting circuit detects a frame rate of image data of a frame in the input image signal. The image processing circuit performs image processing on the image data of the frame to generate a target pixel value of multiple pixels in the frame. The response time enhancing circuit determines multiple adjusted pixel values of the multiple pixels according to the frame rate, and outputs the adjusted pixel values to a display panel. For a pixel, the adjusted pixel values generated for the pixel under different frame rates are different.Type: GrantFiled: March 8, 2017Date of Patent: October 16, 2018Assignee: MSTAR SEMICONDUCTOR, INC.Inventors: Meng-Yu Tsai, Dien-Shen Chiang

Patent number: 9320835Abstract: Provided are a polymer composition on a substrate and a surface modification method which is non-selective to substrate materials. Chemical vapor deposition polymerization is used to deposit a maleimide-functionalized poly-p-xylylene coating on a substrate. The substrate is readily available to perform a thiol-maleimide coupling reaction under mild conditions so as to modify the surface thereof. Furthermore, through a tailored thiol-terminal molecule, a designer surface can be created via thiol-maleimide coupling on a substrate, and the resulting surface can exhibit various desired biological functions for biotechnological applications. Therefore, this modification technique can be applied to biological fields extensively.Type: GrantFiled: March 15, 2013Date of Patent: April 26, 2016Assignee: National Taiwan UniversityInventors: Hsien-Yeh Chen, Sheng-Tung Huang, Meng-Yu Tsai
