13 RT4831 is a multifunctional device that can provide power to the LCD display
14 and LCD backlight.
16 For Display Bias Voltage DSVP and DSVN, the output range is about 4V to 6.5V.
17 It's sufficient to meet the current LCD power requirement.
19 For the LCD backlight, it can provide four channel WLED driving capability.
