Product Summary
The ADJD-J823 is a color management controller with integrated rgb photosensor 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 ADJD-J823 samples the light output from the RGB LED array, pro­cesses the color information and adjusts the light output from the RGB LEDs until the target color is achieved. To achieve this, the ADJD-J823 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.
