Abstract
A method and an apparatus for setting a gamma reference voltage, and a driving circuit are provided, which decrease a driving voltage of a display apparatus and reduce power consumption by resetting the gamma reference voltage of the display apparatus. The method comprises: acquiring a dielectric constant of a liquid crystal capacitor according to a first gamma reference voltage (); acquiring a value of the liquid crystal capacitor according to the dielectric constant of the liquid crystal capacitor (); acquiring a feedback voltage according to the value of the liquid crystal capacitor, acquiring a second gamma reference voltage according to the feedback voltage, and updating the first gamma reference voltage to the second gamma reference voltage (). The method and apparatus for setting a gamma reference voltage, and the driving circuit may be applied to production and manufacture of a liquid crystal display.
