Abstract

The invention relates to the technology field of a double color LED state indicating apparatus, and provides a double color LED state indicating apparatus that comprises a cell charging management module, a cell, an LED control circuit and a CPU control module; the LED control circuit is connected with the cell charging management module and is also connected with the CPU control module, in this way, the LED control circuit can prompt the cell charging state and can control LED scintillation frequency to prompt different work states of equipment.

Description

technical field [0001] The invention belongs to the field of circuits, and in particular relates to a device capable of indicating states with two-color LEDs. Background technique [0002] In the field of consumer electronics and electronic technology, general electronic devices are powered by Ni-MH batteries or rechargeable batteries of other materials and related display units, such as digital tubes, liquid crystal displays, OLED displays, and the like. In the process of using an electronic device, whether it is turned off or turned on, when charging the electronic device, on the one hand, the electronic device needs to clearly prompt the user with status information such as charging and charging; on the other hand, in normal operation In the state, electronic equipment is required to provide easy-to-understand operating conditions and current working status information. For example, in GPS+ Beidou satellite positioning and navigation equipment or other wearable electronic...
