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.

Abstract: The present application provides a liquid crystal display panel, a liquid crystal display device, and an electronic device. By removing portions of a first polarizer and a second polarizer of the liquid crystal display panel that corresponds to a light-transmitting area, light can be transmitted in the light-transmitting area of the liquid crystal display panel. In addition, by setting a first liquid crystal layer in the light-transmitting area of the liquid crystal display panel to allow a portion of the liquid crystal display panel corresponding to the light-transmitting area in a display state.
