Have you ever seen the time in the dark via mobile phone?In this case,bright backlight and dark environment are in sharp contrast.which makes eyes uncomfortable.Therefore, it is necessary to adopt ICON mode,that's to say,it displays LCD panel time or the user defined picture through tiny current.If this must be realized by PWM brightness control,then the processor generates a continuous low frequency PWM signal in standby mode.In NCP5602, the function is realized by using hardware and commanding figures.The typical RGB LED driver chip application circuit with I2C interface is showed as the picture.
