  • Gate driver and method for adjusting output channels thereof
    Patent number: 10049606
    Abstract: A gate driver and a method for adjusting output channels thereof are provided. The method includes: setting a target number of the output channels; dividing the output channels into a first channel chain and a second channel chain; enabling a scanning operation of the first channel chain according to a clock signal and counting the clock signal to obtain a counting value; and when the counting value reaching a threshold value, enabling a scanning operation of the second channel chain, wherein the threshold value is determined according to a difference value between the target number and the physical number.
    Type: Grant

  • Speech synthesis method and apparatus for electronic system
    Patent number: 9087512
    Abstract: A speech synthesis method for an electronic system and a speech synthesis apparatus are provided. In the speech synthesis method, a speech signal file including text content is received. The speech signal file is analyzed to obtain prosodic information of the speech signal file. The text content and the corresponding prosodic information are automatically tagged to obtain a text tag file. A speech synthesis file is obtained by synthesizing a human voice profile and the text tag file.
