Patent number: 9541956Abstract: A supporting structure and a docking station using the same are provided. The supporting structure includes an elastic member, a sliding member, a lifting element and a damper. The sliding member having an inclined plane is connected to the elastic member. When the elastic member receives a force, the elastic member forces the sliding member to move along an axis line with the inclined plane facing to the lifting element. The lifting element is arranged over a travel path of the inclined plane and has an abutting portion. When the lifting element receives another force so that the abutting portion abuts against the inclined plane, the sliding member stops moving and the height position of the lifting element is fixed. The damper is mated with the sliding member to slow down the velocity of the sliding member.Type: GrantFiled: November 12, 2014Date of Patent: January 10, 2017Assignees: UNIVERSAL SCIENTIFIC INDUSTRIAL (SHANGHAI) CO., LTD., UNIVERSAL GLOBAL SCIENTIFIC INDUSTRIAL CO., LTD.Inventors: Ming-Jen Chen, Kuo-Kuang Liu, Yu-Chen Chu, Chang-Cheng Lin

Patent number: 7812802Abstract: An overdrive accuracy adjustment device and method for use in a liquid crystal display panel is presented. According to a current grayscale value of a pixel in an awaiting to be displayed image and a previous grayscale value of the corresponding pixel in an already-displayed image, the corresponding overdrive grayscale value is found from a look-up table. In order to more efficiently use the limited storage capacity of the look-up table as well as improve the accuracy of the overdrive, in accordance with the physical characteristics of the liquid crystal display panel in particular (in particular to the grayscale values which often require the overdrive), the gap size between the current grayscale values and/or the gap size between the previous grayscale values may be adjusted in the look-up table, without having to increase the quantity of the overdrive grayscale values stored in the look-up table.Type: GrantFiled: February 15, 2007Date of Patent: October 12, 2010Assignee: VastView Technology Inc.Inventors: Chang-Cheng Lin, Yuh-Ren Shen, Cheng-Chung Peng

Patent number: 7683877Abstract: A double-frame-rate method for reducing the time lapse of a LCD pixel between its two consecutive scans within a frame is provided. The method horizontally partitions the scan lines into (k) non-overlapping regions, each containing m1, m2, . . . , mk scan lines. The method then scans each of the regions twice before continuing to the next region and, as such, completes two passes of scanning of the entire frame. For a pixel in a region (j), the time lapse between the pixel's two consecutive scans during the frame's frame time is (mj/n) of the time lapse of conventional double-frame-rate methods.Type: GrantFiled: September 30, 2005Date of Patent: March 23, 2010Assignee: VastView Technology Inc.Inventors: Yuh-Ren Shen, Yu-Lin Lee, Chang-Cheng Lin
