Description
Technical Field
The present disclosure relates to the field of electronic circuit technologies, and more particularly, to a method and an apparatus for driving an indicator light of a mobile device, and a mobile device.
Background
At present, mobile devices such as smart phones and tablet computers are used as personal mobile and multimedia application terminals, functions are more and more powerful, and prompt information displayed through a human-computer interaction interface is more and more abundant. Although the display function of the screen of the mobile device is powerful, the power consumption of displaying the prompt message through the screen is large due to the high power consumption of the screen and the characteristic that the screen must be driven by the main controller, and therefore, the general message reminding function is completed through the indicator lamp. Generally, the indicator light prompts a lot of information, for example, when the mobile device is in a charging state, has a missed call, has a short message, and does not view an application prompting message, the indicator light flashes, lights up normally, or is in a "breathing" lighting state to prompt the user, where the "breathing" lighting state refers to a state where the indicator light is turned on in a preset color and gradually increases the brightness to the brightest state in a process of needing information prompting, and gradually decreases the brightness until turning off after the brightest state lasts for a certain time, and the "breathing" lighting state not only lights up and off regularly and periodically like breathing, but also the lighting and turning-off switching process smoothly changes according to a certain curve, thereby presenting a personified "breathing" effect.
The indicator light for achieving the "breathing" lighting state is generally composed of three LED light emitting diodes (or LED beads), which are generally used to emit blue light (B), red light (R), and green light (B), respectively. In practical application, the forward conducting voltage V of each LEDFIt is not strictly uniform, so a constant current source driving circuit is usually used to provide the driving current for the LED. For the indicator lamp, the presented color is determined by the proportion of current components flowing through the three LED light-emitting diodes of R/G/B respectively. In order to keep the color breathing lamp to change only in brightness and keep the color unchanged during breathing, a pulse code modulation (PWM) technology is mostly adopted to synchronously control the duty ratios of the driving currents output to the three LED light emitting diodes, wherein the higher the duty ratio is, the higher the brightness of the output is, the smaller the duty ratio is, the lower the total brightness is, and the proportion of the three current components of R/G/B is kept unchanged regardless of any brightness level.
In the prior art, the driving process of the indicator lamp of the mobile device is mainly completed by a control and driving circuit in an LED driving chip, when the indicator lamp needs to be started, a main controller of the mobile device sends an external instruction to the LED driving chip, configures or modifies state parameters of the indicator lamp, and then starts the LED driving chip to output driving current to the indicator lamp. After the external instruction is sent, the main controller enters a sleep mode, and only the control and driving circuits in the LED driving chip work independently, so that the mobile device is maintained in a low power consumption state, and just in order to avoid frequent work of the main controller, if various information conditions exist at the same time, as the situation that missed calls, unread short messages, unread WeChat messages and the like need to be prompted, the driving circuit in the LED driving chip in the prior art can only select one lamp effect according to priority to display, that is, when various information needs to be prompted, only one information can be prompted, and various information needing to be prompted cannot be comprehensively prompted.
