Mouthful, differential signal unit is shown by reinforcing a video card in mainboard video card rgb signal output end, connects two kinds of data-interfaces respectively
Display, realize simultaneously support two kinds of complete different sizes display device, reduction design cost.
To achieve the above object, the technical solution adopted in the utility model is：A kind of mainboard shows to LVDS displays with EDP
Show that the compatibility interface of device, including video card show differential signal unit, monitor signal output interface, the video card shows difference letter
Number unit includes shared output driver, LVDS chips, EDP chips, constant-current source output driver；
The shared output driver is provided with rgb signal input port, LVDS signal output ports, EDP signal output parts
Mouthful, mainboard video card rgb signal output end is connected on outside the rgb signal input port, the LVDS chips are defeated by LVDS signals
Exit port is connected with shared output driver, and the EDP chips are connected by EDP signal output ports and shared output driver
Connect；
The constant-current source output driver is provided with motherboard power supply input port, two constant-current source output ports, the mainboard
Be connected on motherboard power supply output end outside power input port, the LVDS chips, EDP chips respectively by constant-current source output port with
Constant-current source output driver connects；
The LVDS chips, input of the EDP chips respectively with monitor signal output interface are connected.
Wherein, the LVDS chips, EDP chips are connected by a pair of difference PCB lines with constant-current source output driver respectively.
Wherein, the monitor signal output interface includes LVDS signal output interfaces, EDP signal output interfaces, described
LVDS chips are connected with the input of LVDS signal output interfaces, and the input of the EDP chips and EDP signal output interfaces connects
Connect.
The beneficial effects of the utility model are：Shown by reinforcing a video card in mainboard video card rgb signal output end
Show differential signal unit, the module can carry out the processing of two kinds of different size data to the rgb signal of mainboard video card output simultaneously.
The video card shows that differential signal unit integrates LVDS chips and EDP chips, the LVDS chips by with shared output driving
The RGB data signal that video card rgb signal exports is converted to the serial LVDS differential signals of low-voltage, the EDP by device synergy
RGB data signal is directly converted to EDP differential signals by chip, and exports corresponding signal by monitor signal output interface
Onto display.Therefore, the signal for exporting two kinds of different sizes simultaneously is realized, and can be in same mainboard according to use environment
The different displays for supporting two kinds of different sizes, reduce the waste of resource.
