It is known that in the application of VMS product,only less than 40 percent area of entire screen is actually operating in working mode. A large number of unused integrated circuit chips are consuming energy. For general VMS product, in black area, an 8mA current will always flow in each IC output channel without sleep mode. For our YHT-VMS product,in the same blank area, only a 10uA current will flow in each channel under sleep mode. A sample calculation for energy saving is showingas follows:For general VMS product, power consumption by each IC driver of 16 output channels will be: 16pin*0.008A*5V=0.64W.For our YHT-VMS product, power consumption by IC driver is reduced to 16pin*0.000010A*5V = 0.0008W. Our YHT-VMS product will save 0.64W/0.0008W=800 times for every single IC driver!
