Patent ID: 8120598

Claim:
A driving apparatus of a display device comprising a plurality of stages connected to each other, wherein: each stage comprises a respective first plurality of transistors and a respective second plurality of capacitors; each stage has respective terminals respectively coupled for receiving a scanning start signal, at least one clock signal, and first and second gate-off voltages Voff 1 and Voff 2 of different magnitudes, where the magnitudes of the first and second gate-off voltages are for application to gates of one or more of said transistors for turning off the respective transistors; at least a first of the first plurality of transistors of each stage is operatively coupled to the respective terminal that is coupled to receive the first gate-off voltage Voff 1 ; and at least a second of the first plurality of transistors of each stage is operatively coupled to the respective terminal that is coupled to receive the second gate-off voltage Voff 2 .
