hi,
I'm using LCD with stm32f107 vct6, I need 5V for backlight.
I configure GPIOC_Pin7 as GPIO_Mode_Out_OD and I connect it with 4K7 resisator and 5V.
GPIOC_Pin7  -------->-------->OUT 
                              4K7
                      ^
                         ^
                    5V 

I measure at OUT it is 3V.
