Abstract:
1. A driving circuit for a display device, comprising a first trigger signal generating stage, a second trigger signal generating stage, . . . , and an n-th trigger signal generating stage, where n is an integer larger than 0, wherein: the first trigger signal generating stage comprises a first shift register to perform a tri-state inversion on an external input signal to obtain a first tri-state inversion signal and the tri-state inversion on the first tri-state inversion signal to obtain an input signal of the second trigger signal generating stage, and further to generate a first scanning signal according to a second logic signal of the second trigger signal generating stage; and the i-th trigger signal generating stage comprises an i-th shift register and an i-th logic gate, where i is an integer between 2 and n, wherein the i-th shift register performs the tri-state inversion on an input signal of the i-th trigger signal generating stage generated by the (i−1)-th trigger signal generating stage to obtain an i-th tri-state inversion signal, and then performs the tri-state inversion on the i-th tri-state inversion signal to obtain an input signal of the (i+1)-th trigger signal generating stage; the i-th logic gate generates an i-th logic signal according to the i-th tri-state inversion signal and the input signal of the (i+1)-th trigger signal generating stage; and the (i−1)-th trigger signal generating stage generates the (i−1)-th trigger signal according to the i-th logic signal.
