This invention provides a shift register, a driving circuit, a display panel, and a display device. In the shift register: a first input unit is used to write a signal to a first node; the control terminal of a first output unit is coupled to the first node, a first terminal of the first output unit receives a first voltage signal, and a second terminal of the first output unit is coupled to a signal output terminal; a second input unit is used to write a signal to a second node; the control terminal of the second output unit is coupled to the second node, a first terminal of the second output unit receives a first clock signal, and a second terminal of the second output unit is coupled to a signal output terminal; the output terminal of a sustaining unit is coupled to the second node, and the sustaining unit is used to maintain the potential of the second node at least during the period when the first output unit is off and the second output unit is on, ensuring that the potential of the second node is maintained during the period when an enable signal is output at the signal output terminal, thus ensuring the output state of the signal output terminal.

The utility model discloses a backlight module capable of preventing an EMI (Electro-Magnetic Interference) shielding film from being reversely pasted, which comprises a lower frame, an FPC (Flexible Printed Circuit) and a rectangular EMI shielding film, the FPC is bent to the lower surface of the lower frame, and a component area is arranged on the FPC; the rectangular EMI shielding film is attached to the lower surface of the FPC, the rectangular EMI shielding film comprises a rectangular black aluminum foil and an insulating layer arranged on the upper surface of the black aluminum foil, the insulating layer completely covers the lower surface of the component area, the rectangular black aluminum foil is attached to the lower frame and the lower surface of the FPC, and the rectangular black aluminum foil is attached to the lower frame and the lower surface of the FPC. And a fool-proof gap is arranged at one vertex angle of the rectangular black aluminum foil. Due to the fact that the fool-proof notch is formed in one vertex angle of the rectangular black aluminum foil, namely, the design that the notch is formed in the right-angle position of one end of the rectangular black aluminum foil is adopted, an assembling worker can clearly check whether the drawing is pasted reversely or not when checking the drawing after pasting, the fool-proof effect is achieved, and meanwhile operation of the assembling worker is facilitated.
