Hi all,
I'm working with NHD‐C0220BiZ‐FS(RGB)‐FBW‐3VM 2x20 LCD display along with infineon TC38x Controller. I found certain programs for interfacing lcd with controller using I2C in NHD‐C0220BiZ‐FS(RGB)‐FBW‐3VM datasheet. I need some help for changing back light of the LCD. Please help, Thanks.

  Hi Dharma,
  
  The 4 LED backlight pins on the side of the display are directly connected to the LEDs.  Each of the 3 color LEDs can be connected to a pulse width modulated current source to provide the level of brightness desired by each color.  In this manner, it is possible to create the specific color you wish to display as the backlight.

  
  
  Best Regards,
