Hello, I'm new to LCD RGB. So currently, I want to control the brightness of the backlight for this LCD :

The pinout of the LCD can be seen in the picture below.

I already searched it on google, it tells me that we can control using PWM, but i dont understand how to use it. The voltage of the LCD and its backlight voltage can be seen in the picture below

The forward voltage is with 18V high. You need a power supply 20V or 24V for that. In the led circuit at 24V a resistor 150Ω 1/4W.

On the net are much schematic how to drive the leds with mosfet and arduino.
