The both ends of one group of distribution channel are all uniquely corresponding to be arranged in the corresponding connector, when the both ends of the distribution channel are distinguished
When being arranged in two connectors, the connector of the distribution channel one end is input, and the distribution channel is in addition
The connector of one end is output end, the internal wiring switching system by switching the conducting states of some groups of distribution channels,
The transmission direction of signal, electric current in control display screen, in the internal wiring switching system simultaneously only one group of distribution channel
In the conduction state, the connector is to carry out the signal between the display screen of arbitrary neighborhood, electric current transmits.
A kind of 10. power supply signal free switching method as claimed in claim 9, it is characterised in that：Internal wiring switching system
Some groups of distribution channels of system include three kinds of conducting states, are respectively conducting up and down, left and right conducting and right angle conducting, this is straight
Angle conducting is divided into upper right conducting, bottom right conducting, bottom left conducting and upper left conducting, four connectors and is separately positioned on the casing
Upper and lower, left and right lateral surface on,
The internal wiring switching system includes internal electric source switch unit and internal signal switch unit, wherein, inside electricity
Source switch unit is to switch the transmission direction of electric current in the display screen, and the internal signal switch unit is switching the display screen
The transmission direction of middle signal,
The internal electric source switch unit includes power switcher and some groups of current paths, if the power switcher passes through switching
The conducting state of the dry group current path, the transmission direction of electric current in the display screen is controlled, in the internal electric source switch unit
Only one group of current path is in the conduction state simultaneously,
The internal signal switch unit includes signal shifter and some groups of signal paths, if the signal shifter passes through switching
The conducting state of the dry group signal path, the transmission direction of signal in the display screen is controlled, in the internal signal switch unit
Only one group of signal path is in the conduction state simultaneously, and the current path and the signal path are arranged on the circulation simultaneously and led to
Lu Zhong.
