Patent ID: 8547366

Claim:
A driving device for outputting a plurality of driving signals which are sequentially asserted to a display array, comprising: a shift register comprising a plurality of stages of shift registering units coupled in series, wherein the shift registering units respectively generate a plurality of shift registering signals, and the shift registering signals are sequentially asserted; a buffer unit for receiving at least one input signal, wherein the at least one input signal is periodically asserted, and the buffer unit outputs the at least one input signal; and a plurality of switch circuits directly connected to the shift registering units to receive the shift registering signals, respectively; wherein, all of the switch circuits are coupled to the buffer unit to receive the at least one input signal, and the switch circuits sequentially output the at least one input signal to serve as the driving signals for the display array according to the assertion of the shift registering signals; and wherein each of the switch circuits comprises: a first switch element having a control terminal receiving the corresponding shift registering signal, a first terminal receiving the first input signal, and a second terminal coupled to a first node; a second switch element having a control terminal receiving the corresponding shift registering signal, a first terminal coupled to the first node, and a second terminal coupled to a ground terminal; and a third switch element having a control terminal receiving an inverse shift registering signal, a first terminal receiving the first input signal, and a second terminal coupled to the first node, wherein the inverse shift registering signal is inverse to the corresponding shift registering signal; wherein the first switch element and the second switch element are separately turned on, the first switch element and the third switch element are simultaneously turned on, and the corresponding driving signal is generated at the first node.
