Technical Field
The utility model relates to a computer mainboard device technical field, concretely relates to can realize computer mainboard that many screens show.
Background
The existing computer mainboard only supports single-screen display generally, and because the Intel chipset does not directly support the double-EDP, double-LVDS and EDP + LVDS display functions, the computer configuration is low, and more user requirements cannot be met. Therefore, in order to meet different requirements of customers and meet diversified requirements of the market, the invention provides a computer motherboard supporting dual-screen display, such as a motherboard supporting dual-EDP, dual-LVDS and EDP + LVDS display.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of prior art existence, through utilizing the existing signal of Intel chipset, change circuit design to collocation software configuration reaches simple structure, and the configuration is nimble and with low costs characteristics, realizes supporting two EDP, two LVDS, EDP + LVDS etc. and shows the demand.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a can realize computer motherboard of multi-screen display, includes main chip and the LVDS1 display interface, LVDS2 display interface, EDP1 display interface and the EDP2 display interface that are connected with it, it has EDP2 converting circuit to communicate between main chip and the EDP2 display interface, it has switching circuit to communicate between main chip and LVDS2 display interface and the EDP1 display interface, it has LVDS2 converting circuit still to communicate between switching circuit and the LVDS2 display interface.
Further low, the EDP2 display interface is connected to the main chip through EDP2 conversion circuitry.
Further, the LVDS2 display interface and the EDP1 display interface share a display channel output from the main chip, and the LVDS2 or EDP1 function is selected by a switching circuit.
Implement the utility model provides a can realize computer mainboard that many screen display show has following profitable technological effect:
1. the circuit design can be changed by utilizing the existing signals of the Intel chipset, and the characteristics of simple structure, flexible configuration and low cost are achieved by matching with software configuration, so that the display requirements of dual EDP, dual LVDS, EDP + LVDS and the like are met;
2. the LVDS1 signal is a natively supported LVDS1 display interface, and additional circuits are required for the LVDS2 signal, the EDP1 signal and the EDP2 signal. The LVDS2 signal and the EDP1 signal share a display channel output from the main chip, and the LVDS2 or the EDP1 function is selected through a switching circuit;
3. EDP2 uses the display channel of a master chip alone. To ensure that each display interface functions properly, some of the control signals from the LVDS1 need to be used by the LVDS2, the EDP1, and the EDP 2.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only one embodiment of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
FIG. 1 is a schematic diagram of a computer motherboard capable of implementing multi-screen display according to the present invention;
fig. 2 is a circuit diagram of a computer motherboard capable of displaying multiple screens.
In the figure: the display device comprises a main chip 1, a display interface 2 LVDS1, a display interface 3 LVDS2, a display interface 4 EDP1, a display interface 5 EDP2, a conversion circuit 6 EDP2, a switching circuit 7 and a conversion circuit 8 LVDS 2.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: a computer main board capable of realizing multi-screen display comprises a main chip 1, an LVDS1 display interface 2, an LVDS2 display interface 3, an EDP1 display interface 4 and an EDP2 display interface 5, wherein the LVDS1 display interface 2, the LVDS2 display interface 3, the EDP1 display interface 4 and the EDP2 display interface 5 are connected with each other, an EDP2 conversion circuit 6 is communicated between the main chip 1 and the EDP2 display interface 5, a switching circuit 7 is communicated between the main chip 1 and the LVDS2 display interface 3 and the EDP1 display interface 4, an LVDS2 conversion circuit 8 is further communicated between the switching circuit 7 and the LVDS2 display interface 3, the EDP2 display interface 5 is connected with the main chip 1 through the EDP2 conversion circuit 6, the LVDS2 display interface 3 and the EDP1 display interface 4 share a display channel output from the main chip 1, and the LVDS2 or EDP1 function is selected through the switching circuit 7.
The utility model discloses a can realize computer mainboard that many screens show can utilize the existing signal of Intel chipset, changes circuit design to the configuration of collocation software reaches simple structure, disposes nimble and characteristics with low costs, realizes supporting two EDP, two LVDS, EDP + LVDS etc. and shows the demand.
The LVDS1 signal is a natively supported LVDS1 display interface, and additional circuits are required for the LVDS2 signal, the EDP1 signal and the EDP2 signal. The LVDS2 signal and the EDP1 signal share a display channel output from the main chip, and the LVDS2 or EDP1 function is selected by one switching circuit. EDP2 uses the display channel of a master chip alone. To ensure that each display interface functions properly, some of the control signals from the LVDS1 need to be used by the LVDS2, the EDP1, and the EDP 2.
