Patent number: 9710875Abstract: 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.Type: GrantFiled: January 20, 2014Date of Patent: July 18, 2017Assignee: VIA TECHNOLOGIES, INC.Inventors: Chien-Cheng Sung, Ping-Huei Hsieh

Patent number: 9361824Abstract: 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.Type: GrantFiled: December 28, 2010Date of Patent: June 7, 2016Assignee: VIA TECHNOLOGIES, INC.Inventor: Ping-Huei Hsieh

Patent number: 7800605Abstract: 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.Type: GrantFiled: August 5, 2005Date of Patent: September 21, 2010Assignee: Via Technologies Inc.Inventor: Ping-Huei Hsieh

Patent number: 7518605Abstract: Mode support systems and methods. The system comprises a storage device and an editing unit. The storage device comprises a first mode list comprising a plurality of display modes. The editing unit edits at least one supported display mode from the display modes in the first mode list, and stores a second mode list comprising the supported display mode to the storage device. The supported display mode in the second mode list is retrieved by a device.Type: GrantFiled: December 12, 2005Date of Patent: April 14, 2009Assignee: Via Technologies, Inc.Inventors: Mo-Hsuan Lin, Te-Wei Fu, Ping-Huei Hsieh

Patent number: 7403210Abstract: 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.Type: GrantFiled: October 31, 2005Date of Patent: July 22, 2008Assignee: VIA Technoologies, Inc.Inventors: Ping-Huei Hsieh, Chia-Ling Wu
