Hi,

Backlight is controlled by pins "A" and "K", pins 40 & 41, not throught the ILI9341.

You have different ways to control the backlight:

1) No control over brightness, via a resistor hard wired.

2) A PWM signal generated by your micro, or through an light sensor.

Have a look at the CAT4139 for controlling backlight.

Thanks,

Thanks for the quick response.

We will refer to the CAT4139.

Thanks again.
