Patent number: 10950156Abstract: A timing controller of a display panel includes a spread spectrum clock generator (SSCG) and a control circuit block. The SSCG performs a spread spectrum operation on a clock signal to output a modulated clock signal having a varying frequency that varies with a fixed pattern, wherein a complete cycle of the frequency variation occurs in a frequency modulation period. The control circuit block outputs display data for the display panel within a data output period related to the modulated clock signal, and outputs a synchronization signal to another timing controller of the display panel, such that the another timing controller synchronizes a spread spectrum operation performed thereby with that performed by the SSCG.Type: GrantFiled: May 14, 2020Date of Patent: March 16, 2021Assignee: NOVATEK MICROELECTRONICS CORP.Inventors: Tzu-Chien Hsu, Yu-Lin Hsu

Publication number: 20140008652Abstract: A through-substrate via structure including a substrate, a conductive layer, and a parasitic capacitance modulation layer is provided. The substrate has at least one opening. The opening is filled with the conductive layer. The parasitic capacitance modulation layer is disposed between the conductive layer and the substrate. The parasitic capacitance modulation layer is placed around the through-substrate via to reduce the depletion capacitance and further reduce the parasitic capacitance of the through-substrate via. Therefore, during transmission of signals with high frequency, the parasitic capacitance around the through-substrate via is rather small and thereby the operation speed of devices is increased.Type: ApplicationFiled: August 20, 2012Publication date: January 9, 2014Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Tzu-Chien Hsu, Tzu-Kun Ku, Cha-Hsin Lin

Patent number: 8299942Abstract: The present invention discloses a composite-image parking-assistant system, which is installed in a vehicle. When a driver drives his vehicle to passes at least one parking space, the system of the present invention uses camera devices to capture images involving the parking space. A processing unit converts the images into bird's eye view images and integrates the bird's eye view images into a composite bird's eye view surrounding map via the common characteristics thereof. A display device presents the surrounding map to the driver. The processing unit adjusts the coverage the vision field of the surrounding map according the relative position of the vehicle and the parking space to make the magnification of the vision field inverse proportional to the relative position. Thereby, the driver can park his vehicle efficiently and avoid collision.Type: GrantFiled: October 6, 2009Date of Patent: October 30, 2012Assignee: Automotive Research & Test CenterInventors: Ming-Kuan Ko, Hsin-Pin Yu, Tzu-Chien Hsu
