资料介绍
The LP5520 is an RGB backlight LED driver for small format
color LCDs. RGB backlight enables better colors on the display
and power savings compared with white LED backlight.
LP5520 offers small and simple driver solution without need
for optical feedback. Calibration in display module production
can be done in one temperature. LP5520 produces true white
light over wide temperature range. Three independent LED
drivers have accurate programmable current sinks and PWM
modulation control. Using internal calibration memory and
external temperature sensor, the RGB LED currents are adjusted
for perfect white balance independent of the brightness
setting or temperature. The user programmable calibration
memory has intensity vs. temperature data for each color.
This white balance calibration data can be programmed to the
memory on the production line of a backlight module.
