SHIFT REGISTER UNIT, SHIFT REGISTER AND DISPLAY DEVICE

摘要

The present invention relates to the technical field of displays, and particularly relates to a shift register unit, a shift register and a display device. The shift register unit in the present invention comprises a first transistor, a second transistor, a third transistor, a fifth transistor, a sixth transistor, a seventh transistor, an eighth transistor and a storage capacitor. Noise reduction is achieved by the shift register unit in the present invention using fewer transistors on the basis of the original signal transfer function, so that not only the output errors probably caused by the drift of the threshold voltage of the transistors themselves, and by the interference of the adjacent transistors and the like are effectively suppressed, but also a narrow frame of a liquid crystal display is realized, the power consumption of a driving circuit is reduced as well, and the output characteristic of the shift register and the service life of the transistors are further improved.
