Display backlight driver ic configuration

A configurable LED controller for use in a computing device, the controller comprising:

• a power on reset detector configured to determine when power is first applied to the configurable LED controller;
• a non-volatile memory configured to store initial LED controller settings;
• one or more registers configured to receive initial LED controller settings from the non-volatile memory when a power-on reset event is detected, wherein LED operation is in accordance with data written into the one or more registers;
• and
• a control signal interface configured to write data into the one or more registers prior to enabling LED output.

A system controlling an LED backlight for a computing device, the system comprising:

• a LED array configured as a backlight for the computing device;
• an LED controller comprising:
• a power on reset detector configured to determine when power is first applied to the LED controller;
• a non-volatile memory including a first set of data for configuring the LED controller in a first operational mode,
• hardware registers configured to receive the first set of data from the non-volatile memory when a power-on reset event is detected, and wherein the LED array is controlled in accordance with data written into the hardware registers, and
• a control signal interface configured to over write data in hardware registers with a second set of data for configuring the LED controller to operate in a second operational mode;
• and
• a timing controller configured to produce a pulse width modulated (PWM) signal for controlling LED brightness when operating in the second operational mode.
