Abstract
PURPOSE: To reduce the power consumption by eliminating the route through which the current flows constantly and at the same time to increase the charging MOSFET regardless of other MOSFET's with forming no inverter within the circuit, thus increasing the scanning speed.
CONSTITUTION: Clear pulse ϕC is applied at t1, and MOSFET115 is turned on to clear the charge of the capacity for MOSFET114 and 118. Then MOSFET113 is turned on at t2 to apply start pulse ϕST to terminal 121, and thus node n1 is set to a high level. The clock ϕ2 is applied in a high level to terminal 120 at t3, and the charging current flows to MOSFET114 to turn scanning output N1 to a high level. And MOSFET117 is also turned on with node n2 set to a high level at t3. Thus output N2 is charged via MOSFET118 to be turned to a high level at t3, and output N1 is set to a low level at the end of t3.
