FIELD: photography.
SUBSTANCE: invention relates to image reproduction. Technical result is achieved by input stage circuit comprising plurality of control GOA sub-blocks connected in cascaded manner; circuits of intermediate stage, containing two control GOA sub-blocks, connected cascaded, while input terminal of the first stage of the control GOA sub-blocks in intermediate stage circuit is electrically connected to output terminal of last cascade of plurality of control sub-blocks GOA in input stage circuit; output stage circuit comprising plurality of control GOA sub-blocks connected cascaded, input terminal of the first stage of plurality of control GOA sub-blocks in output stage circuit is electrically connected to output terminal of last stage of control GOA sub-blocks in intermediate stage circuit.
EFFECT: technical result is to improve efficiency of control of gate driver circuit in matrix.
