Abstract: A light-emitting structure, a backlight module, a display module, and a display device are provided. The light-emitting structure includes a circuit substrate, including a first surface and a second surface sequentially arranged along a light-exiting direction of the light-emitting structure. The circuit substrate also includes a light-transparent substrate and a wiring structure located on a side of the light-transparent substrate in a thickness direction. The light-emitting structure also includes a plurality of light-emitting elements, arranged in an array on one of the first surface or the second surface of the circuit substrate. The plurality of the light-emitting elements is electrically connected to the wiring structure. The light-emitting structure also includes a heat sink, located on a side of the first surface of the circuit substrate. The heat sink is configured for dissipating heat generated by the plurality of the light-emitting elements.

Abstract: A shift register includes a forward/backward scan-control module, configured to transmit a signal of a forward-scan-signal terminal or a signal of a backward-scan-signal terminal to a first node; an interlock module, configured to transmit a signal of a first voltage terminal to a second node, and transmit a signal of a second voltage terminal to the first node; a pull-down module, configured to transmit the signal of the first voltage terminal to a gate-signal output terminal; an output module, configured to transmit a signal of a second clock-signal terminal to the gate-signal output terminal; and a reset module, configured to transmit the signal of the second voltage terminal to the first node, and transmit the signal of the first voltage terminal to the gate-signal output terminal. The disclosed shift register can prevent leakage of the first node, and thus improve the quality and the performance of the shift register.
