  • Patent number: 9710875
    Abstract: An image transmission apparatus for providing a low voltage differential signaling (LVDS) data stream to a display panel is provided. The image transmission apparatus includes a transmitter and a graphic processing unit (GPU). The transmitter obtains an extended display identification data (EDID) according to an inter integrated circuit signal from the display panel. The GPU provides configuration data according to the EDID, and provides a display port (DP) data stream according to an image data. The transmitter obtains a transfer parameter according to the configuration data, and converts the DP data stream into the LVDS data stream according to the transfer parameter.

  • Patent number: 9361824
    Abstract: A graphics display system is provided with a graphics processing module and a display module. The graphics processing module detects whether first frame data is equal to second frame data subsequent to the first frame data, and in response to the first frame data being equal to the second frame data, stops outputting any frame data after outputting the second frame data and a mode switching command. The display module displays graphic images according to the first frame data, and stores the second frame data as temporary data and continuingly displays the graphic images according to the temporary data in response to the mode switching command.

  • Patent number: 8868811
    Abstract: One embodiment is a method for establishing a link between a source device and a sink device. The method comprises enabling a hot plug detect (HPD) handler in the source device, utilizing the HPD handler to receive an HPD interrupt upon the sink device being coupled to the source device, applying one or more predetermined parameters corresponding to the HPD interrupt to establish the link between the source device and the sink device, and adjusting the one or more predetermined parameters if the link between the source device and the sink device is not established.

  • Patent number: 7800605
    Abstract: Multi-view video switching control methods and systems are disclosed. It is determined whether a VBI (vertical blanking interval) of signals respectively transmitted by a first GA (graphic array) and a second GA is detected. The video source of first and second GAs belongs to the same first video source. If the VBI corresponding to first GA is detected first, the video source of first GA is switched to a second video source, and the video source of second GA is switched to the second video source if the VBI corresponding to second GA is then present. If the VBI corresponding to second GA is detected first, the video source of second GA is switched to the second video source, and the video source of first GA is switched to the second video source if the VBI corresponding to first GA is then present.

  • Patent number: 7403210
    Abstract: Display mode management systems and methods. The system comprises a plurality of supported display modes, and a processing module. The processing module receives an expected display mode, and determines whether the expected display mode is among the supported display modes. If not, a specific display mode is selected from the supported display modes. The resolution of the specific display mode is smaller than and closest to that of the expected display mode among the supported display modes. The specific display mode is set as the display mode of a device.
