Abstract

PURPOSE: To eliminate the fluctuation caused by the temperature and other factors by controlling the maximum and minimum levels of the application voltage so that they may be kept at the primary correlation between the intermediate level and the display brightness.
CONSTITUTION: Display signal 33 to be displayed via the liquid crystal is mixed with the signal sent from picture pattern generation circuit 31 properly at mixer circuit 32 to be supplied to liquid crystal driving circuit 27. And this output is supplied to liquid crystal display substance 28. Damping circuit 30 applies the feedback signal to circuit 27 while the signals given from circuit 31 are being applied to the liquid crystal so that the detection signal of liquid crystal action level detector 29 may be at the optimum position.
