Abstract:
1. A one-stage shift register comprising: a first transistor with a drain electrode thereof connected to a corresponding one of scanning lines and with a source electrode thereof connected to a power supply; a second transistor of a same conductivity type as the first transistor, with a drain electrode thereof coupled to a common node with a gate electrode of the first transistor, with a source electrode thereof connected to the power supply, and with a gate electrode thereof connected to a first external control signal line; a third transistor of the same conductivity type as the first transistor, with a drain electrode thereof coupled to the common node of the drain electrode of the second transistor, with a source electrode thereof connected to the power supply, and with a gate electrode thereof connected to a node that uses a bootstrap effect; and a load circuit with one end thereof connected to a second external control signal line and with the other end thereof connected to the drain electrode of the second transistor.
