Abstract

The invention discloses a power supply discharge circuit, a display module and a display device. The power supply discharge circuit comprises at least one discharge branch, at least one discharge branch is in one-to-one correspondence with at least one voltage output end, and the discharge branch comprises a first switch and a second switch; the first ends of the first switches are electrically connected with the corresponding voltage output ends, and the second ends of the first switches are electrically connected with the power utilization module; the first end of the second switch is electrically connected with the second end of the first switch, the second end of the second switch is grounded, and the control end of the second switch is electrically connected with the power-off signaloutput end; The power supply discharge circuit comprises a control module which is electrically connected with the power-off signal output end; the first end of the control module is electrically connected with the control end of the first switch, and the second end of the control module is connected with a conduction signal; and the conduction signal is used for conducting the first switch. According to the embodiment of the invention, the power utilization module can be rapidly discharged.

Description

technical field [0001] Embodiments of the present invention relate to discharge technology, in particular to a power supply discharge circuit, a display module and a display device. Background technique [0002] With the development of electronic technology, the application of power supply is becoming more and more extensive, and accordingly, the discharge requirements between the power supply and the power consumption module are also getting higher and higher. [0003] However, the existing power supply cannot quickly discharge the power consumption module after the power is cut off, and the power consumption module will be affected by the residual charge when it is powered on again, seriously affecting the performance of the power consumption module. Contents of the invention [0004] The invention provides a power supply discharge circuit, a display module and a display device for rapid discharge when the power is cut off. [0005] In the first aspect, an embodiment of...
