A kind of tiled display control method, for the mosaic screen be spliced to form by several display units, connected in turn between each display unit by Serial Port Transmission line, described method comprises:
A display unit incoming control signal is chosen arbitrarily from several display units;
Control signal by control signal forward and reversely transfer to the next display unit of selected display unit and a upper display unit respectively, and is transferred to the inside of selected display unit by Serial Port Transmission line by selected display unit simultaneously;
Next display unit control signal is transferred to its inner and by Serial Port Transmission line by control signal again forward transfer to again next display unit, more next display unit again to control signal transmit until all be connected to selected display unit in turn after display unit all receive control signal till;
Control signal is transferred to that it is inner and by Serial Port Transmission line, control signal another mistake is gone up a display unit again to transferring to by a upper display unit, a upper display unit again to control signal transmit until all be connected to selected display unit in turn before display unit all receive control signal till.
Another technical scheme of the present invention is:
A kind of tiled display control system, comprise the mosaic screen be spliced to form by several display units, connected in turn by Serial Port Transmission line between each display unit, each display unit is internally connected with for the control signal receiver module of incoming control signal and the control signal commutation circuit that is connected with control signal receiver module, described control signal commutation circuit is used for from control signal receiver module reception control signal or from the upper display unit forward reception control signal of the display unit belonging to it or the reverse reception control signal of next display unit from the display unit belonging to it, then the control signal received is transferred to its inner also forward and transfer to the next display unit of display unit belonging to it and/or the reverse upper display unit transferring to display unit belonging to it.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Control signal of the present invention not only can be transmitted by forward, all right reverse transmission, any one display unit when not changing signal wiring in mosaic screen can incoming control signal, and control signal is by the display unit forward of this access and/or reversely transfer to each display unit step by step.Because control signal of the present invention can pass through any one display unit Access Control whole system, no longer be limited to some display units, when control signal point changes without the need to changing the connecting line of system, convenient and simple, enhance practical and the extendability of splice displaying system control.
