Description
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.
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.
