Abstract

According to the backlight module, the liquid crystal display screen and the using method of the liquid crystal display screen, the liquid crystal display screen comprises a liquid crystal display panel, a backlight module capable of being switched between a transparent state and a backlight state, and an optical element; by means of the backlight module capable of being switched between the transparent state and the backlight state, the technical problem that an existing liquid crystal display screen is difficult to transmit light can be solved without damaging the integrity of a full screenand increasing the damage possibility and the maintenance cost of a mobile phone, and normal display and use of the optical element can be achieved on the same liquid crystal display screen; and possibility is provided for realizing a real liquid crystal display full screen without a mechanical structure.

Description

technical field [0001] The present application relates to the display field, in particular to a backlight module, a liquid crystal display screen and a method for using the liquid crystal display screen. Background technique [0002] At present, full-screen technology has become the main direction of LCD screen development. Full-screen has the advantages of large viewing area, high screen-to-body ratio, and good visual effects, and has attracted widespread attention in applications such as mobile phones. [0003] However, for the demand for front optical components in these devices, such as selfie cameras, optical fingerprints, light / distance sensors, infrared cameras, etc., traditionally designed LCD screens can only be reserved on the screen due to their difficulty in transmitting light. The bangs or opening area, or in a lifting manner, pops up the various optical elements mentioned above. The former of these two solutions destroys the integrity of the full screen, while...
