Abstract

In a backlight module, a liquid crystal display screen, and a using method thereof provided, the liquid crystal display screen includes a liquid crystal display panel, a backlight module switchable between a transparent state and a backlight state, and an optical component. Without disrupting full screen display and increasing a possibility of cellphone damages, the backlight module may solve a problem that the liquid crystal display screen is opaque to light, such that the screen is normally displayed, and the optical component is operated on the same liquid crystal display screen.
