SHIFT REGISTER, DRIVE CONTROL METHOD OF SAME, AND DISPLAY DRIVING DEVICE PROVIDED WITH SAME

摘要

PROBLEM TO BE SOLVED: To provide a shift register which allows a stable circuit operation to be performed, a drive control method of the same, and a display driving device provided with the same.

SOLUTION: Each stage of shift circuits in this shift register is provided with a TFT11 which makes a Node A high-level when an output signal out (k-1) is input from a preceding stage shift circuit to an input terminal IN; a TFT17 which outputs a high-level output signal out (k) when the potential of the Node A is set to a high level; a TFT12 which lowers the potential of the Node A, when an output signal out (k+1) is input as a control signal from a following stage to a reset terminal RST; a TFT16 which raises the potential of a Node B in response to the potential fall of the Node A; a TFT19 which quickly raises the potential of the Node B in response to the input of an output signal out (k+1); and a TFT18 which makes the output signal out (k) low-level when the potential of the Node B is set to high level.
