TFTs / 2.4" TFT LCD Brightness Control
« on: April 01, 2014, 05:23:24 AM »
Hello,

I am using NHD-2.4-240320SF-CTXI#-FT1 LCD which has built-in ILI9340 controller. I connected the LCD's backlight LED pins directly to a power source and they are working good (internally biased). I want to control the LCD's brightness through the ILI9340 controller's backlight control registers but am unable to change the brightness level using those registers.

I want to know, can the LCD's backlight be controlled through ILI9340 registers or do I need to control the brightness externally through some circuit.

Thanks!
