Display power savings

Present liquid crystal displays require drive voltages up to 30 V depending on the type MOS integrated circuits are therefore quite suitable to drive them. As liquid crystal displays also consume very little power, it follows that power-saving driver circuits should also be used [61, 62]. 

The backlight control can adapt to the illumination situation in various environments. Furthermore, power-saving displays are also possible. 

Only large gas turbines of multi-MWei size and low rpm diesel engine generators of 1 MW and more can display efficiencies above 40% [11], thus competing with modem coal-fired power plants. Nevertheless, considering the avoidance of grid losses and the dramatically increased total conversion efficiency, a clear case can be made for CHP units with respect to reductions in CO2 emissions and fossil fuel savings.
