Selectable Cooling Mechanism of LCD Monitor

   Disclosed is LCD Monitor's cooling fan control system.The system controls suitable internal air flow path for monitor's landscape and portrait position by changing each fan's rotating direction and speed automaticaly by hardware or software.

Fig.1 and Fig.2 shows typical example of a case managing landscape and portrait position's fan cooling with the monitor's fan set. This is a case that there are free opening hole. Opening hole's characteristic wheather it's suction inlets or discharge outlets depends upon the condition of fans' set, A, B, and C. Fig. 1 shows rear view of monitor's landscape position. There will be a case that A anb B are the fans at suction inlets. C is the fan at discharge outlet. Fig. 2 shows rear view of monitor's portrait position. B and C are the fans at suction inlets. A is the fan at discharge outlet. Comparing fans' condition at landscape and portrait position, fan A and C 's rotating direction are reversed.

Fig.3 and Fig.4 shows typical example of a case without opening holes. In this case, all internal air flow is controlled directly by fan set, Fans A, B, C, and D
