Patent ID: 8552962

Claim:
A display apparatus driving circuit comprising: a source driver for driving a display unit; a heat detecting circuit for detecting amount of heat generated at said 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; wherein said heat detecting circuit receives at least part of image data on a row basis, compares first data in row p and second data in row p+1 out of the received image data so as to detect a value based on a difference between the first data and the second data as the generated heat amount, where p is a natural number, and detects, as the generated heat amount, the number of successive frames in which absolute differences of the first data and the second data in one frame is larger than a predetermined first threshold for the number of times equal to or larger than a predetermined second threshold.
