Posted on September 03, 2012 at 05:47In my application I want to reduce the power consumption as much as possible, so after a while of no activity detected in the board the system turns off the screen, just writing a cero in the PWM which controls the screen backlight.
After that, the system should goes into the standby mode, when this happens the screen lights up again.
In order to fix it, I turn off the display from the register of the screen, writing a cero in the register 7 of the color LCD, but when it goes into the standby mode, the screen has the same behavior and turns on again, but this time with nothing in the screen, just a white background.
