Re-visiting a classic laptop recycling manoeuvre in an age of more complicated backlight drivers
Here’s a better photo of the modified LCD driver. The LED backlight driver is an ADD5201 (https://www.analog.com/media/en/technical-documentation/data-sheets/ADD5201.pdf). I changed the configuration resistors to put it in direct-PWM mode then tied the backlight enable and PWM pins high (to the 3.3v rail conveniently generated inside the driver IC).
And uhhh cut off the useless remainder of the PCB with some scissors. Which was satisfying.
