I am using STLD41 as backlight driver for 5.7"controllerless TFT.
Whenever STLD41 gets on it produces lines on TFT & display gets disturbed.If i give backlight power seperately from power supply Display works  fine.I checked for VDD(Main 3.3V as well as Backlight 9.5V) while STLD41 is ON,it's almost ripple free. How to handle this problem?? Please share if any body have any experience about it.

Thanks & Regards
