Color Management Controller with Integrated RGB Photosensor

Data Sheet

Description

Features

The ADJD-J823 is a CMOS mixed-signal IC with integrated

RGB photosensors designed to be the optical feedback

device of an RGB LED-based backlighting system. A

typical system consists of an array of red, green and blue

(RGB) LEDs, LED drivers and the ADJD-J823. The device

samples the light output from the RGB LED array, pro-

cesses the color information and adjusts the light output

from the RGB LEDs until the target color is achieved. To

achieve this, the device integrates an RGB photosensor

array, an analog-to-digital converter front-end, a color

data processing logic core and a high-resolution 12-bit

PWM output generator.

• Integrated RGB photosensor

• Integrated color management feedback controller

• Serial Interface

• Direct interface to standard I2C EEPROM

• 3-channel 12-bit PWM output –

Red, Green and Blue LED channels

• Built-in oscillator

Applications

• LCD Backlighting

By employing a feedback system and the ADJD-J823,

the light output produced by the LED array maintains

its color over time and temperature. In addition, using

a serial interface, specifying the color of the LED array’s

light output is as simple as picking the target color co-

ordinates from the CIE color space and writing several

bytes of data to the device.

The sensitivity of the device to light can be adjusted

through an automated process. The PWM output signals

control the on-time duration of the red, green and blue

LEDs. That duration is continually adjusted in real-time

to match the light output from the RGB LED array to the

target color.

ESD WARNING: Standard CMOS handling precautions should be observed to avoid static discharge.
