Claim Text:
1. An AMOLED (Active Matrix Organic Light Emitting Diode) panel driving circuit, comprising: an AMOLED panel, a gate driver electrically connected to the AMOLED panel, a source driver electrically connected to the AMOLED panel, a timing controller electrically connected to the source driver, and a gamma IC (Integrated Circuit) electrically connected to the source driver, the timing controller being further electrically connected to the gate driver and the gamma IC, the timing controller using two sets of gate control signal to control the gate driver, the source driver supplying a data signal to the AMOLED panel, the data signal comprising a plurality of data frames, each of the data frames comprising a plurality of sub-data-frames having equal time intervals; and further comprising a multiplexer electrically connected to the timing controller, the multiplexer comprising a high level input pin, a low level input pin, an enable control signal input pin, and a selective output pin, the gamma IC comprising a static high voltage pin, the static high voltage pin having a voltage that is constantly greater than or equal to voltages of output pins of the gamma IC, the enable control signal input pin being electrically connected to the timing controller, the selective output pin being electrically connected to the static high voltage pin of the gamma IC, the high level input pin being adapted to receive a high level signal, the low level input pin being adapted to receive a low level signal, the low level signal being 0V, whereby when the timing controller supplies a source enable control signal to the multiplexer to allow the source enable control signal to control the multiplexer to supply a 0V voltage signal to the static high voltage pin of the gamma IC, the output pins of the gamma IC output voltages that are 0V, the output pins comprising first and fourteenth output pins.
