Claim:
1. An image transmission apparatus for providing a low voltage differential signaling (LVDS) data stream to a display panel, comprising: an LVDS connection port coupled to the display panel; a transmitter coupled to the LVDS connection port, obtaining a first extended display identification data (EDID) according to an inter integrated circuit (I2C) signal from the display panel via the LVDS connection port; and a graphic processing unit (GPU) coupled to the transmitter via a transmission line of a display port (DP) standard, providing configuration data according to the first EDID from the transmitter via the transmission line, and providing a DP data stream to the transmitter via the transmission line according to an image data, wherein 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, wherein the transmitter provides the LVDS data stream to the display panel via the LVDS connection port, wherein the GPU comprises: a storage unit, storing a plurality of EDID, wherein when the GPU obtains an identification data from the display panel via the transmitter, the GPU obtains a second EDID corresponding to the display panel from the plurality of EDID of the storage unit according to the identification data, and provides the configuration data according to the second EDID.
