  • Circuit for updating firmware of display apparatus and method thereof
    Patent number: 8375378
    Abstract: The present invention relates to a circuit for updating firmware of a display apparatus and a method thereof. An optional update unit may be used for initializing the updating process. The first firmware information of the first display apparatus is transmitted to the second display apparatus for updating the second firmware information of the second display apparatus. Hence, reliability is enhanced and problems of incompatibility will not occur. In addition, no extra burning devices will be necessary, thus reducing extra cost.
    Type: Grant
    Filed: August 2, 2007
    Date of Patent: February 12, 2013
    Assignee: Realtek Semiconductor Corp.
    Inventors: Ching-Tzong Wang, Szu-Ping Chen
  • Synchronization control apparatus and method
    Patent number: 7623185
    Abstract: A synchronization control apparatus for driving a display module in an interlacing scan mode includes: a delay circuit for delaying an input vertical sync (IVS) signal to generate a delayed signal; and a multiplexer coupled to the delay circuit for selecting one of the IVS signal and the delayed signal according to an odd/even field indication signal to generate an output vertical sync (OVS) signal.

  • METHOD OF GENERATING VIDEO DRIVING SIGNAL AND APPARATUS THEREOF
    Publication number: 20080001939
    Abstract: A method of generating a video driving signal is disclosed. The method includes: compressing the first image data to generate a compressed data; delaying the compressed data; decompressing the compressed data to generate a decompressed image data; and comparing a second image data and the decompressed image data to generate an overdrive signal; wherein the overdrive signal corresponds to the second image data.
