Abstract
PURPOSE: To ensure the operation of the liquid crystal element even at a low temperature by varying the element driving voltage according to the temperatures.
CONSTITUTION: The output of temperature sensor 1 is supplied to switch circuit 4, and circuit 4 supplies the output of low voltage circuit 2 to outside in the form of the liquid crystal driving voltage in case the ambient temperature exceeds the fixed level. When the ambient temperature lowers less than the fixed level, sensor 1 detects the lowering to make circuit 4 supply the output of high voltage circuit 3 to outside. As a result, the increase of the threshold voltage of the liquid crystal element under the fixed temperature and then the increment of the operation time can be compensated by increasing the driving voltage, thus ensuring the driving of the liquid crystal element even under the low temperatures
