Abstract

The invention provides a drive circuit and an electronic device. A soft start module is used for receiving an externally input first signal and outputting a second signal; rising speed of voltage of the second signal meets a first preset condition. A voltage stabilizing module is used for controlling stable voltage for the second signal output by the soft start module and outputting a stabilized voltage third signal to a circuit board. The voltage stabilizing module is connected with both the soft start module and the circuit board. Therefore, damage of devices in the circuit, caused by changes in input voltage, can be avoided, and normal use of the electronic device is ensured.

Description

technical field [0001] The present invention relates to the field of electronic technology, and specifically may relate to a driving circuit and an electronic device. Background technique [0002] Existing electronic devices are composed of several circuits (or circuit boards) capable of realizing different functions, such as various circuit boards and chips included in liquid crystal displays. [0003] However, in the existing circuit boards and chips, there are some devices or circuits that are sensitive to changes in the external input voltage. When the external input voltage changes greatly, there may be damage and breakdown of the devices or circuits. The normal use of the electronic device is affected. Contents of the invention [0004] The invention provides a drive circuit and an electronic device, thereby avoiding damage to devices in the circuit due to changes in input voltage and ensuring normal use of the electronic device. [0005] The present invention prov...
