The AS3824 is a 16-channel LED TV backlight controller which performs local dimming of sections of a display screen to provide both improved picture quality and valuable power savings of up to 20% to 30%.
The AS3824 backlight controller is intended for use in the latest high-definition (HD) and ultra-high-definition (UHD, or 4K) televisions, as well as high dynamic range (HDR) monitors and displays.
The AS3824 includes a fully flexible 12-bit PWM generator for each of its 16 channels, to enable sections of a display screen to be dimmed independently. Each PWM generator may be synchronized with an external synchronization signal.
The local dimming enabled by the AS3824 also provides for additional system power savings compared to global backlight controllers.
