Other Parts Discussed in Thread: DM3730, TPS61165
Hi,all
platform:DM3730
OS:WINCE 6.0
Backlight Driver IC:TPS61165
I used GPMC_nCS5(a pad in DM3730) to implement PWM LCD backlight Brightness control. when I waked up my systerm afte suspending,the LCD backlight flicker for a moment,
but the LCD backlight will stop flickering after a period of time. i.e. The LCD backligth would be ok as long as I don't suspended and waked up the systerm. I checked the
pwm signal by Oscilloscope,The pwm signal was normal.my design has been attached here(i.e. backlight_pwm.pdf), who can give me some ideas? why the LCD flicker?
