The first EDP interface 190 and the second EDP interface 320 may employ BTW connectors. The display 400 may employ the display 400 having a single channel LVDS signal interface or a dual channel LVDS signal interface.

As for the EDP interface and the LVDS interface, the host 300 having only the EDP interface cannot be electrically connected to the display 400 having only the LVDS interface. Specifically, the EDP to LVDS signal module 180, the first EDP interface 190 and the first LVDS interface 210 are disposed on the substrate 110 of the screen adapter board 100, so that the second EDP interface 320 on the host 300 is electrically connected to the first EDP interface 190 on the screen adapter board 100, the second LVDS interface 450 on the display 400 is electrically connected to the first LVDS interface 210 on the screen adapter board 100, and the EDP to LVDS signal module 180 on the screen adapter board 100 converts the EDP signal output by the host 300 into an LVDS signal and transmits the LVDS signal to the display 400.

The display 400 with the first LVDS interface 210 can be used with a different host 300 with the second EDP interface 320 through the screen adapter board 100, and the screen adapter board 100 improves the compatibility between the display 400 and the host 300 and reduces the cost of the host 300. If the display 400 with the first LVDS interface 210 is used with a different host 300 with the second EDP interface 320, the host 300 needs to be modified to change the EDP interface to the LVDS interface, or the host 300 is added with the LVDS interface, which increases the cost of the host 300, and the host 300 is connected to the display 400 with the first LVDS interface 210 after adding the LVDS interface, which causes the second EDP interface 320 on the host 300 to be idle, resulting in waste of resources. Similarly, the host 300 with the second EDP interface 320 can be used with a different display 400 with the first LVDS interface 210 via the screen adapter board 100.

In addition, since the display 400 with one size has an optimal resolution, when different hosts 300 and displays 400 are used in combination, if the optimal resolutions recorded on different hosts 300 are different, only the optimal resolution of one of the hosts 300 is the same as the optimal resolution of the display 400, then when the hosts 300 are used in combination with the display 400, only the host 300 with the optimal resolution that is the same as the optimal resolution of the display 400 can optimize the display effect of the display 400, while the other hosts 300 cannot optimize the display effect of the display 400, the compatibility between the display 400 and the hosts 300 is poor, and since each host 300 is recorded with an optimal resolution, resources are wasted and costs are increased. Therefore, by burning the optimal resolution of the display 400 with the corresponding size on the EDP to LVDS signal module 180 of the screen adapter plate 100, each display 400 can display the optimal resolution under the condition that the displays 400 with the same size are connected to different hosts 300 through the screen adapter plate 100, thereby improving the compatibility between the display 400 and the host 300, saving resources and reducing cost.
