Abstract
A color liquid-crystal display panel has a red filter segment in each red sub-pixel and a blue filter segment in each blue sub-pixel, but no green filter segment in green sub-pixels. The liquid-crystal display panel has a backlight source for illuminating, and the backlight source has green light producing components alternately switched on and off in consecutive frames. The backlight source also has white or red/blue, or purple light emitting components alternately switched on and off in consecutive frames in complementary phase to the green light producing components. When the liquid crystal layer segments associated with all the three color sub-pixels are operated in a light non-blocking state, only the white or red/blue light producing components are turned on, and when the liquid crystal layer segments associated with the red sub-pixels are operated in a light blocking state, only the green light producing components are turned on.
