DRIVING CIRCUIT OF LIQUID CRYSTAL DISPLAY PANEL

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of an overshoot and an undershoot caused by an excessive correction in the driving circuit of a liquid crystal panel that applies a correction voltage in which the change in a transmissivity is emphasized. SOLUTION: The transmissivity of liquid crystals at the completion of a previous display period is beforehand estimated from the display data of the previous display period within a certain range. Using the above fact, a voltage which causes no undershoot/overshoot is applied to the liquid crystals in a current display period even though the transmissivity of the liquid crystals is a maximum value or a minimum value within the range.
