Abstract
It is provided a method of controlling a shift register in which a plurality of transfer unit circuits, each having a storage unit and a writing unit, are connected in series. The storage unit has a hold gate and stores a logical level of a pulse when the hold gate is in an active state, and the writing unit has a writing gate and stores a pulse in the storage unit when the writing gate is in an active state. The method includes: performing control such that the writing gate is shifted from the active state to the non-active state and then the hold gate is shifted from the non-active state to the active state, when the writing gate is shifted from an active state to a non-active state and the hold gate is shifted from a non-active state to an active state; and performing control such that the hold gate is shifted from the active state to the non-active state and then the writing gate is shifted from the non-active state to the active state, when the writing gate is shifted from the non-active state to the active state and the hold gate is shifted from the active state to the non-active state.
