FLICKER COMPENSATING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To reduce the influence due to a temperature change in compensation of flicker and to improve productivity. SOLUTION: The flicker compensation circuit is equipped with a capacitor 31 for inputting the common voltage generated for the common electrode of a plurality of liquid crystal pixels and a variable resistor 32 for changing the central level of the common voltage inputted via the capacitor 31. Further, the flicker compensation circuit is equipped with a switch section 34 for selecting one of the first and second prescribed voltages varying from each other and output sections 33 and 35 for outputting the output of the variable resistor 32 and the output of the switch section 34 in superposition to the common electrode.
