Abstract:
A display apparatus driving circuit capable of reducing the amount of heat generated at a driving unit while suppressing degradation in image quality is provided. A display apparatus driving circuit according to the present invention includes: a source driver for driving a display unit; a heat detecting circuit for detecting amount of heat generated at the source driver, and outputting a heat detection signal when the detected amount of generated heat is equal to or larger than a predetermined reference value; and a heat reduction circuit for changing, when the heat detection signal is received, a driving method of the display unit to reduce the amount of heat generated at said source driver.
