Title:
SHIFT REGISTER
Document Type and Number:
WIPO Patent Application WO/2024/033742
Kind Code:
A1
Abstract:
The present invention provides a novel signal output circuit. The present invention provides a shift register which has a signal output circuit that comprises a vertical channel transistor. The present invention enables the achievement of a signal output circuit which occupies a small area by using one of the gate-source parasitic capacitance and the gate-drain parasitic capacitance of the vertical channel transistor, the one having a higher capacitance, for a bootstrap capacitor. The present invention is capable of shortening the channel length by using an oxide semiconductor for a semiconductor layer of the vertical channel transistor, thereby enhancing the withstand voltage between the source and the drain. The present invention also enables a stable operation in a high temperature environment.
