Control connection power supply processing unit and signal processing unit, the isolated location include connecting bridge, and the power supply processing unit leads to
Cross connecting bridge connection signal processing unit；Signal input module, the signal input module connect with signal processing unit, are used for
Signal is passed to；DID splices module, and the power supply processing unit and signal processing unit splice module with DID
Connection shows for exporting.
Preferably, the signal input module includes HDMI ports, DVI ports, VGA port, AV ports and DP
Port.
Preferably, the DID splicings module includes backlight constant current unit and screen body TCON logic card lists
Member.
Preferably, the power supply processing unit receive 176V~265V/50Hz alternating voltages be transformed to 5V, 12V,
The DC voltage of 24V.
The advantageous effect of two-in-one DID mosaic screens board card device is disclosed in the utility model：OSD menu list is controlled in MCU
Control connection power supply processing unit and signal processing unit, power supply processing unit pass through the connecting bridge inside isolated location to member respectively
Connection signal processing unit, isolated location effectively block interference of the power supply processing unit to signal processing unit, lead to simultaneously
It crosses connecting bridge and realizes power supply processing unit and signal processing unit is powered, simplify structure, therefore reduce Material Cost,
Mounting structure is simplified, reduces installation procedure, improve production efficiency and improves the convenience of after-sales service.
Description of the drawings
Fig. 1 is the structure diagram of the two-in-one DID mosaic screens board card device of the utility model.
Specific embodiment
The utility model is further elaborated and illustrated with reference to specific embodiment and Figure of description：Please refer to figure
1, a kind of two-in-one DID mosaic screens board card device, including two-in-one combination board card module 10, signal input module 20 and DID
Splice module 30.
It is single that two-in-one combination board card module 10 includes control OSD menu unit 11, power supply processing unit 12, isolation in MCU
Member 13 and signal processing unit 14, in MCU control OSD menu unit 11 respectively control connection power supply processing unit 12 to electric current, electricity
The output amplitude and signal processing unit 14 of pressure handle the signal of external world's input, and isolated location 13 includes connecting bridge 131,
Power supply processing unit 12 passes through 131 connection signal processing unit 14 of connecting bridge.Isolated location 13 effectively blocks power supply processing
Interference of the unit 12 to signal processing unit 14, while power supply processing unit 12 is realized to signal processing by connecting bridge 131
