A charger is a static current conversion device that uses power electronic semiconductor devices to convert AC power with a fixed voltage and frequency into DC power. In order to make it more convenient and user-friendly for users, chargers with display functions have been produced. Chargers with display functions use a mixed digital-analog method to display the power consumption, current changes, voltage changes, and other power consumption of the device on an LCD screen, which is conducive to mastering the power consumption of the device. Compared with traditional applications that use LED lights to light up, darken, and flash to indicate the charging status, chargers with display functions provide clearer and more intuitive display effects. This allows users to understand the battery charging status more accurately and better manage their devices. In addition, the display can also display other parameters of the charger, such as temperature, protection status, etc., to facilitate user operation and settings.
