Description
Technical field
This application involves electronic circuit technology fields, more specifically to a kind of driving side of mobile device indicator light
Method, driving device and mobile device.
Background technology
The mobile devices such as current smart mobile phone, tablet computer are more next as personal movement and multimedia application terminal, function
More powerful, the prompt message shown by human-computer interaction interface is more and more abundant.Although the display function of the screen of mobile device
It is powerful, but due to the high power consumption of screen and the characteristic that must be driven by master controller so that pass through the display reminding of screen
The power consumption of information is larger, and therefore, general prompting message function is all completed by indicator light.In general, indicator light prompts
Information it is relatively more, such as be in charged state in mobile device, have missed call, there is short message and do not check Application Hints message
When, indicator light all can into line flicker, be always on or prompt user in " breathing " illuminating state, wherein " breathing " illuminating state
Refer to being connected with preset color during needing to carry out information alert and gradually increasing brightness to most bright state, most bright
Brightness is continuously decreased after state certain time until the state extinguished, this " breathing " illuminating state are the same not only like breathing
With having the rhythm and pace of moving things, periodically light on and off, and light on and off handoff procedure changes according to certain curve smoothing show " exhaling of personalizing
Inhale " effect.
Realize that the indicator light of " breathing " illuminating state is usually made of three LED light emitting diodes (or LED lamp bead), this
Three LED light emitting diodes are usually respectively used to transmitting blue light (B), feux rouges (R) and green light (B).In actual application, often
The forward conduction voltage V of a LED light emitting diodesFIt is not strict conformance, so, generally use constant current source driving circuit is LED
Light emitting diode provides driving current.For above-mentioned indicator light, the color showed is by respectively flowing through R/G/B tri-
The current component ratio of LED light emitting diodes determines.It is brightness change in respiratory to keep colored breath light, and
Color keep is constant, mostly uses pulse code modulation scheme (PWM) and carrys out output of the synchronous control to three LED light emitting diodes
The duty ratio of driving current, duty ratio is bigger, and the brightness of output is higher, and duty ratio is smaller, and total brightness is lower, regardless of any bright
Grade is spent, the ratio of tri- current components of R/G/B remains unchanged.
In the prior art the driving process of the indicator light of mobile device mainly by LED drive chip control and driving electricity
Road is completed, and when needing start indicator lamp, the master controller of mobile device sends external command to LED drive chip, configuration or
The state parameter of indicator light is changed, then starts LED drive chip to indicator light output driving current.External command is sent
Afterwards, master controller enters suspend mode, and the driving circuits only relied in LED drive chip work independently, so that mobile
Equipment maintains lower power consumption state, also precisely in order to avoiding master controller frequent operation, if there are many information feelings simultaneously
When condition, such as when having missed call, unread short messages simultaneously, not reading wechat and need prompt, in LED drive chip in the prior art
Driving circuit a kind of lamp effect can only be selected to be shown according to priority, that is to say, that when there are much informations to need to carry out
When prompt, a kind of information can only be prompted, the much information for needing to prompt can not be prompted comprehensively.
