Patents by Inventor Chia-Hsing Hou

Chia-Hsing Hou 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).

  • Patent number: 11804195
    Abstract: The disclosure provides a display equipment, a brightness compensation device, and a brightness compensation method. The brightness compensation device includes a variable refresh rate (VRR) detection circuit and a control circuit. The VRR detection circuit and the control circuit receive a video stream from a video source device, and the video stream includes a VRR video frame. The VRR detection circuit detects a blanking period of the VRR video frame and generates a detection result. The control circuit outputs the frame data of the VRR video frame to the display device during the valid data period of the VRR video frame. The control circuit repeatedly outputs the frame data of the VRR video frame to the display device during the blanking period of the VRR video frame according to the detection result until the blanking period ends.

  • Patent number: 9787937
    Abstract: A display apparatus that is suitable for a video wall and an operation method thereof are provided. The display apparatus includes a display panel, a memory circuit and a video processing circuit. The memory circuit is used for storing extended display identification data (EDID), and resolution information of the EDID may affect a resolution of a video frame signal of a video source. The video processing circuit transmits the video frame signal to a video output connector. Based on a video wall configuration parameter, the video processing circuit captures part or all of pixel data in the video frame signal to obtain a captured frame, and displays the captured frame on the display panel. Based on the video wall configuration parameter, the video processing circuit can adaptively change the resolution information of the EDID stored in the memory circuit.
