Patents by Inventor Chang-Pao Chang

Chang-Pao Chang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Display apparatus and data driving integrated circuit thereof
    Patent number: 11443667
    Abstract: The disclosure provides a display apparatus and a data driving integrated circuit thereof for removing the interference patterns caused by radio wave interference. In the disclosure, a data driving integrated circuit includes a gamma voltage generating circuit, power terminals for receiving power voltages of the gamma voltage generating circuit. The data driving integrated circuit couples dummy terminals to the power terminals, so as to decrease the equivalent impedance of the power terminals through a parallel connection between the I/O ESD protection circuits. Therefore, the DC offset of the power voltages caused by the radio wave interference may be decreased.
    Type: Grant
