Title:
SHIFT REGISTER CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/016557
Kind Code:
A1
Abstract:
A shift register circuit and an electronic device, related to the technical field of integrated circuits. The shift register circuit comprises a number m of cascaded flip-flops, clock input terminals of at least some of the flip-flops among the 2nd stage to the m-th stage of flip-flops being provided with a clock control circuit, the clock control circuit receiving an initial clock signal, coupling a data input terminal of an n-th stage of flip-flops and a data output terminal of an (n+1)-th stage of flip-flops, and being used to control the (n+1)-th stage of flip-flops to perform data sampling when an instruction signal received at the data input terminal of the n-th stage of the flip-flops is an effective level, and to control the (n+1)-th stage of flip-flops to stop data sampling after the effective level of the instruction signal is outputted by the (n+1)-th stage of flip-flops. A shift register circuit capable of reducing power consumption is provided.
